No action is requested. EXECUTIVE SUMMARY This report has been prepared to keep the Utilities Advisory Commission (UAC) apprised of the major issues that are facing the water, gas, electric, wastewater collection and fiber utilities including legislative/regulatory issues, utility-related capital improvement programs, operations, reliability impact measures and a utility financial summary. This updated report does not include information about energy efficiency and water conservation programs; that information is provided in an annual Demand Side Management Report attached to the Q2 Utilities Quarterly Report. The UAC will be provided with copies of a separate quarterly climate report containing information about greenhouse gas reduction programs such as electric vehicle charger installations and heat pump water heater replacements. Items of special interest in this report are summarized below: Vacancies and Staffing – Appendix B The Utilities Department has 43 vacant positions out of 269 authorized positions or a 16% vacancy rate at the end of FY 2025 compared to 48 vacancies or 18% vacancy rate in December 2024. Six of the 43 vacant positions are currently on hold. Three of the positions were added in FY 2024 to support fiber- to-the-premises (FTTP). These FTTP positions are on hold depending on the outcome of the FTTP pilot. The other three positions are meter readers which are being held due to the rollout of advanced meters. Electric Utility: Supply cost for FY 2025 was $76.2 million, a 2% decrease compared to budget primarily driven by increased revenue from renewable energy credit and resource adequacy sales. (Section 1.1.1) Staff will recommend Council approval of a standalone battery energy storage system (BESS) and is pursuing some additional solar energy resources. (Section 1.1.3) Palo Alto’s reliability compares favorably to that of Pacific Gas & Electric Company (Section 1.3) Electric sales volumes in FY 2025 were 12.4% higher than forecasted, mainly driven by new data center load. (Section 1.4.1) Gas Utility: Gas prices have been relatively low and stable. (Section 2.1) Two gas main replacement projects and a repair are underway. (Section 2.2) Item #1     Packet Pg. 4     Staff Report: 2501-4079 – Page 2 of 45 Gas sales in FY 2025 were 13% lower than forecasted due to a late start to the heating season. (Section 2.4.1) Water Utility: As of August 1, Regional Water System storage was 93% of maximum. (Section 3.1) Water sales for FY 2025 were close to the forecast. (Section 3.4.1) Wastewater Utility: Actual wastewater sales revenues for FY 2025 tracked closely with the budget. (Section 4.3.1) Fiber Utility: Dark fiber sales in FY 2025 were $3.7 million or 8% higher than forecasted due to a large one-time connection fee. (Section 5.4.1) The permit for the fiber hut has been approved. Construction of the foundation at Colorado power station will begin in September 2025. The fiber hut is anticipated to be delivered by end of 2025. (Section 5.1) Legislative and Regulatory: Changes to the state’s Cap & Trade Program beyond 2030 are expected. (Section 7.1) Legislative: o AB 825 (Petrie-Norris) was amended to replace SB 540 as the vehicle for Pathways legislation to establish a regional day-ahead electricity market and change the language to be more favorable for a successful market. The Governor signed AB 825 into law on September 19th. o AB 1207 (Irwin)1 – This amended Cap-and-Trade bill was signed into law on September 19th. The bill extends the Cap-and-Trade program until 2045 and explicitly states that there should be no impact on how POUs utilize existing allowances. This legislation would also shift some allowances from gas corporations to electrical distribution utilities, but those additional allowances would have to be distributed to ratepayers as a credit. The legislative language is silent on whether the California Air Resources Board (CARB) can change allowance allocations distributed to utilities in the future, but major changes would have to be brought back to the legislature. o SB 2542 (Becker) – This bill was signed into law on September 19th. SB 254 would, among other things, reduce the frequency of wildfire mitigation plan reporting requirements to once every four years. Cap & Trade Revenues: An update regarding the proceeds from the sale of allocated allowance to the Electric and Gas Utilities is provided. (Appendix D) Infrastructure Reports: The Electric and Water Utilities Annual Infrastructure Maintenance and Replacement Reports are provided (Appendixes E and F) 1 AB 1207 (Irwin)

Its electric supply portfolio is 100% carbon neutral. The City maintains and operates an electric distribution system but does not operate any transmission lines or any generating capacity on its own. Instead, the City belongs to Northern California Power Agency (NCPA) which operates its Calaveras hydroelectric generating plant and provides power scheduling services for its other generating resources. This carbon free power is supplied through power purchase agreements with various generation operators. 1.1 Electricity Supply and Transmission Below is an update on electricity supply and transmission services. 1.1.1 Forecasted Supply Costs The electric net supply cost for FY 2025 was $76.2 M, which represents a 2% decrease from the Adopted Budget level of $77.0 M. The most significant change to the net supply cost was an increase in revenue from renewable energy credit (REC) and resource adequacy (RA) sales, but these were partially offset by a decrease in surplus energy revenue. Additionally, RA and market purchases cost less than expected. For FY 2026, electric net supply cost is projected to increase to $99.2 M, driven primarily by an increase in Western Restoration Fund costs, transmission costs, and RA purchase costs. During Q4 of FY 2025, net supply cost was about $1.5 M lower than the adopted budget. Figure 1: FY 2025 Financial Plan Supply Cost Forecast vs. Actuals Item #1     Packet Pg. 9     Staff Report: 2501-4079 – Page 7 of 45 1.1.2 Hydroelectric Conditions The City receives power from two hydroelectric projects, the Calaveras project and the Western Base Resource contract for federal hydropower from the Central Valley Project.5 The watershed for Western hydropower is primarily in the northern end of California, while the watershed for the Calaveras project is in the Central Sierras. Following the wet water year of 2023-2024, reservoir levels across the state began this water year at above average levels. As we approach the end of water year 2024-2025, precipitation levels have been near average levels. As of July 31, precipitation in northern California is about 5% above average for this time of year, while central California is 33% below average. As a result of these conditions, hydro generation levels were roughly average for FY 2025 and are expected to be slightly above average for the following two years, with total output of about 125% of the long-term average level for FY 2026 through FY 2027. Figure 2: Hydro Generation: FY 2025-2027 Actuals & Projections (GWh) 1.1.3 Renewable Energy Procurement As discussed at the July 2025 UAC meeting, staff actively participated in NCPA’s 2024 Request for Proposals (RFP) for new renewable energy and storage projects6, ultimately recommending a contract for a 50 MW share of the Trolley battery energy storage system (BESS). After negotiations for a solar-plus-storage project fell apart near the finish line, staff has begun discussions with another municipal utility about acquiring a portion of their solar portfolio that they no longer need. Staff will continue to actively pursue these discussions, as well as participate in NCPA’s 2026 RFP for renewable energy and storage resources and will report back to the UAC as new developments arise. 1.2 Capital Improvement Plan Status The following capital projects are currently in progress or have been recently completed: EL-17001 (East Meadow Circles 4/12kV Conversion) This project is scheduled to be completed in several phases. Phase 1 is completed. Phase 2 engineering design is completed. Phase 2 construction will be completed June 2026. EL-10006 (Rebuild Underground 24) This project is in the design phase and scheduled to be completed in December 2025. Construction will be completed by December 2026. EL-16000 (Rebuild Underground 26) 5 The Calaveras project is a hydropower project located in Calaveras County that is maintained and operated by the Northern California Power Agency on behalf of the City and other project participants. The City is also one of several public entities with contracts with the Western Area Power Administration for “Base Resource” electricity, which is the hydroelectric power available from the federal government’s Central Valley Project (operated by the Bureau of Reclamation) after accounting for power used for Central Valley Project operations and power delivered to certain “preference” customers. 6 NCPA’s RFP yielded a total of 29 proposals – nine for standalone solar projects, nine for standalone battery energy storage systems (BESS), and 11 for solar-plus-storage projects.

The project will be completed in multiple phases and will take additional years to complete. All engineering design phases are expected to be completed by February 2026. Construction will be completed by December 2026. EL-19004 (Wood Pole Replacement) CPAU staff and contract consultants are continuously working on pole replacement designs for construction. In FY 2025, 66 poles were replaced. The replacement of poles will continue to be prioritized in the Grid Modernization area. EL-16003 (Substation Physical Security). This project is scheduled to be completed in two phases. Substation Security lighting and camera contract was awarded in June 2022. The installation for the first phase was completed for 7 of the 9 substations in December 2024. The bid package for the 2nd phase and final two substations is being prepared for solicitation. Construction is expected to be completed by December 2026. EL-17002 (Substation 60kV Breaker Replacement) This project funds the purchase and replacement of both 60kV and 12kV substation circuit breakers that are reaching the end of their useful life expectancy. Council approved the purchase request for the sixteen 12KV circuit breakers and eight 60kV breakers. The installation of the 12kV breakers is complete. The project to purchase the eight 60KV breakers was approved by City Council on May 20, 2024. The engineering design and installation of the 60kV breakers will begin in FY 2026 and is anticipated to be completed in conjunction with other planned work at the Colorado Substation. EL-21001 (Foothills Rebuild) This project will underground approximately 9 miles of overhead line in Foothills Park, as necessary to lower the risk of wildfires due to overhead electric lines. Staff has completed 39,200 feet of substructure work and de- energized an equivalent amount of overhead electric lines. Substructure for Phase 1 was completed in Spring 2022 and the substructure for Phase 2 was completed in June 2023. Phase 3 construction is 100% complete with substructures and cable installed and energized. Phase 4 construction has completed 12,000 feet of the planned 22,000 feet. Council recently approved of an easement that will allow construction of the remaining 10,000 feet. Phase 5 substructure installation along Arastradero road is 100% completed with all substructure and cable installed and energized. All work is expected to be complete before the end of fiscal year 2026 All substructure work remaining on Phase 4 and the installation of long-lead time, pad-mounted equipment is planned for completion by the end of fiscal year 2026. Utility Pole removal in Phases 1, 2, 3, and 5 is planned for completion by end of calendar year 2025. Utility pole removal in phase 4 is planned for completion by the end of fiscal year 2026 The expanded scope to underground residential service drops is planned for completion by the end of fiscal year 2026 EL-02011 (Electric Utility Geographic Information System (GIS)) The project scope includes on-going maintenance/technical support of the existing GIS system and implementation of the new GIS platform, ESRI. EL-24000 (Grid Modernization) The Pilot project was completed in April 2025. 66 poles have been replaced in the Grid Modernization Pilot area. Additionally, 908 homes in the Pilot area are ready for electrification. Engineering design and material procurement is in progress for the remainder of Phase 1. Target date for Engineering design is December 2025 and construction to follow (12-18 months). 1.3 Reliability CPAU tracks electric power outages through industry recognized indices; System Average Interruption Duration Index (SAIDI), System Average Interruption Frequency Index (SAIFI), and Customer Average Interruption Duration Index (CAIDI). The chart below summarizes outage indices for Palo Alto. With this quarterly update, staff is presenting both outage indices with and without the impacts of “major event days” (MED). For Palo Alto, a MED is defined as a 24-hour period that impacts more than 10% of Palo Alto’s electric customers. By including and excluding MED, staff can review both the impact of major events versus more typical day-to-day operations.

The pie chart to the right presents the number of sustained unplanned outages by their primary cause. For CPAU, most unplanned outages are related to equipment (failure, damage or worn out). The next two largest causes of power outages are trees outages and outages where the cause could not be determined (unknown). Equipment failures continue to be the leading cause of outages, indicating a need for ongoing planned equipment replacements through funding of the City’s Capital Improvement Program.

In June 2024, Council approved the FY 2025 Electric Utility Financial Plan9 , that approved a residential system average rate increase of 9% and a transfer of $17 M from the Electric Operations Reserve to the Hydroelectric Stabilization reserve. This transfer was completed in FY 2024 and will enhance the utility's ability to manage supply cost volatility in the future. Staff provided a financial forecast projection to the Council in June 2025 (Staff Report 2411-3776, Item 2210). According to staff’s latest forecast, the operations reserve balance at the end of FY 2025 is projected to be $29 M, which reflects approximately a $3 M reduction from the prior year and is below the minimum guideline range of $34 M.11 However, by the end of FY 2026 staff forecasts that the operations reserve with return to $51 M, which is close to the target level of $55 M and that the reserve will remain within the guideline range throughout the forecast period. 9 Staff Report 2404-2842, Attachment D, Exhibit 2: https://www.cityofpaloalto.org/files/assets/public/v/2/agendas-minutes-reports/reports/city- manager-reports-cmrs/attachments/2024-rates/electric-utility-financial-plan-fy25.pdf 10 Staff Report 2411-3776 https://cityofpaloalto.primegov.com/viewer/preview?id=0&type=8&uid=35104f06-6925-4fe3-89c7-b0e53e6eec42 11 Staff Report 2411-3776, Attachment D, Exhibit 1 FY 2026 Electric Utility Financial Forecast and CIP Detail https://www.paloalto.gov/files/assets/public/v/2/agendas-minutes-reports/agendas-minutes/city-council-agendas- minutes/2025/june-16/rates-attachments/finalized-attachment-d-exhibit-1-fy26-electric-utility-financial-forecast-and- cip-detail.pdf Item #1     Packet Pg. 14     Staff Report: 2501-4079 – Page 12 of 45 2 Gas Utility The City’s gas utility serves all residential and non-residential gas demand in Palo Alto. The City maintains and operates a system of low-pressure gas lines for delivering gas but does not operate any transmission lines. Costs for the gas utility are split approximately two thirds for the operation, maintenance, and capital improvement and one third for the cost of the gas commodity, PG&E gas transmission, compliance with the State’s Cap and Trade Program and the City’s Carbon Neutral Gas Program. 2.1 Gas Supply and Transmission After experiencing a notable price spike during winter 2022-2023, natural gas prices have seen a significant decline, returning to more typical ranges. This shift can be attributed to several factors, including milder temperatures and above average gas storage levels nationwide. The combination of these factors has kept natural gas prices low, and we do not expect an extreme price spike to occur in the near future. The chart below shows Palo Alto’s gas commodity rates from July 2021 through June 2025. Figure 6: Palo Alto Gas Commodity Rates Item #1     Packet Pg. 15     Staff Report: 2501-4079 – Page 13 of 45 2.1.1 Actual and Forecasted Supply Costs Actual supply costs in FY 2025 were approximately 22% lower than budgeted in the FY 2025 Financial Plan. This variance was primarily driven by low natural gas prices, which remained well below initial forecasts. In June 2025, actual costs exceeded budget due to increased activity in the industrial segment. About half of the increase was due to higher consumption, which normalized in July; the remainder resulted from a billing issue that charged one customer for two months in a single cycle. Figure 7: Gas Supply Costs ($), Actual vs Budget, FY2025 2.2 Capital Improvement Plan Status The following capital projects are currently in progress: GS-15000 – GMR 25 (Gas Main Replacement 25) The GMR 25 project will replace approximately 26,000 linear feet of gas mains on Ross Road from Colorado Avenue to East Meadow Drive and surrounding streets, as well as North and Southampton Drive and surrounding streets, and Walter Hays Drive and surrounding streets. Construction on the project is anticipated to begin in early 2026 and finish in mid-2027. A $16.5 million reimbursable grant from the Pipeline and Hazardous Material Safety Administration was awarded for this project. GS-25001 – Gas Line Repair at Arastradero Creek During the 2023 winter storms, portions of Arastradero Creek eroded away and exposed a gas pipeline crossing Arastradero Creek. This project completed the data gathering phase and will begin the design and permitting phase of the work. A permanent solution will be presented to the permitting agencies (Water Board, CDFW, USACE) in August 2025 for input. Construction on this project is anticipated in mid-2026 through mid-2027. All work will take place in the Pearson Arastradero Preserve. GS-16000 – GMR 26 (Gas Main Replacement 26) The GMR 26 project will replace approximately 26,000 linear feet of gas mains in the Midtown, Palo Verde, Fair meadow, and Evergreen Park neighborhoods. The project is currently in design with construction anticipated in mid-2027. 2.3 Reliability The City of Palo Alto tracks all gas service interruptions. A summary chart of these interruptions can be found below. Gas service interruptions are usually due to repairs of broken or damaged gas services and mains. This kind of damage is often caused by excavation by outside parties digging in the City. In FY25 Q1 we recorded higher numbers in our gas service Item #1     Packet Pg. 16     Staff Report: 2501-4079 – Page 14 of 45 interruption tracking due to the division allocating more resources to resolve existing gas leaks. These leaks are small and are monitored, however expected changes in gas legislation will require them to be resolved more quickly. The gas division has been proactively working to meet upcoming compliance goals before the new rules go into effect.

This was due to one-time expense items deferred from FY 2023 to FY 2024, such as carbon offset purchases and Cap and Trade revenue transfers, together with the impact on reserves from the unprecedented gas price spike in FY 2023. In June 2024, Council approved the FY 2025 Gas Utility Financial Plan15 that included a 12.5% increase in gas rates in FY 2025 to gradually restore reserves to within guideline levels and cover rising costs. Staff provided a financial forecast projection to the Council in June 2025 (Staff Report 2411- 3776, Item 2216). Based on staff’s latest forecast, the operations reserve balance at the end of FY 2025 is projected to be $11.7 million, which is within the guideline range and reflects an increase from the prior year.17 15 Staff Report 2404-2842, Attachment C, Exhibit 1: https://www.cityofpaloalto.org/files/assets/public/v/2/agendas-minutes-reports/reports/city- manager-reports-cmrs/attachments/2024-rates/gas-financial-plan-fy25.pdf 16 Staff Report 2411-3776 https://cityofpaloalto.primegov.com/api/compilemeetingattachmenthistory/historyattachment/?historyId=35104f06- 6925-4fe3-89c7-b0e53e6eec42 17 Staff Report 2411-3776, Attachment C, Exhibit 1 FY 2026 Gas Utility Financial Forecast and CIP Detail https://www.paloalto.gov/files/assets/public/v/2/agendas-minutes-reports/agendas-minutes/city-council-agendas-minutes/2025/june-16/rates- attachments/finalized-attachment-c-exhibit-1-fy26-gas-utility-financial-forecast-and-cip-detail.pdf Item #1     Packet Pg. 18     Staff Report: 2501-4079 – Page 16 of 45 3 Water Utility The Water Utility serves water to virtually all Palo Alto residential and non-residential customers. All potable water in the City is from the San Francisco Public Utilities Commission (SFPUC) Hetch Hetchy Water System. This system delivers high quality water from the Sierra Nevada and uses no pumping to deliver water to the City. Palo Alto uses a small amount of recycled water for irrigation of the Municipal Golf Course and a few other sites near the Regional Water Quality Control Plant. The City also maintains a system of reservoirs and wells that enable Palo Alto to serve water during an interruption of the Hetch Hetchy system. Costs for the Water Utility are split approximately half for the operation, maintenance and periodic replacement of Palo Alto’s water system and half for the costs of the water purchased. 3.1 Water Supply and Transmission As of August 1, 2025, cumulative Hetch Hetchy Weather Station precipitation for Water Year (WY) 2025 was 87% of median, and the Regional Water System total storage operated by the San Francisco Public Utilities Commission (SFPUC) was at 93% of maximum storage and the Water Bank was full. In the figure below, the solid black line shows storage in the Regional Water System for the past 12 months (color bands show contributions to total system storage) and the dashed black line shows total system storage for the previous 12 months. Regional Water System Storage is 1,375 Thousand Acre Feet (TAF) as of August 1, 2025. Figure 11: Regional Water System Storage The figure below shows water usage for the South Bay/East Bay (including Palo Alto) compared to several benchmarks, including 2015, 2023 and a five-year average. For the South Bay/East Bay region as well as systemwide, demand for 2025 has been similar to the average of the last five years and generally higher than the same months in 2023, which had historically wet weather.

Figure 14: Water Sales Volume (CCF), FY 2025 Figure 15: Water Sales Revenue ($), FY 2025 Item #1     Packet Pg. 21     Staff Report: 2501-4079 – Page 19 of 45 3.4.2 Financial Position At the end of FY 2024, the Water Operations Reserve balance was $7.1 million, which is below the minimum guideline range of $8.4 million. Additionally, the rate stabilization reserve had $4 million remaining at the end of FY 2024. In June 2024, Council approved the FY 2025 Water Utility Financial Plan21, which approved a 9.5% rate increase in FY 2025 to pay for rising costs and offset decreased sales revenues. Staff provided a financial forecast projection to the Council in June 2025 (Staff Report 2411-3776, Item 2222). According to staff’s latest forecast, the operations reserve balance at the end of FY 2025 and FY 2026 is projected to decline further to $6.1 million and $5.6 million, respectively as the utility continues to use reserves to pay for operating costs.23 During this time, the remaining $4 million from the Rate Stabilization Reserve will also be used to pay for operating costs. As rates increase over time, by FY 2027, the operations reserve will begin to restore and by the end of FY 2028 the operations reserve is projected to be $10.2 million, which is within the guideline range. 21 Staff Report 2404-2842, Attachment B, Exhibit 1: https://www.cityofpaloalto.org/files/assets/public/v/1/agendas-minutes-reports/reports/city- manager-reports-cmrs/attachments/2024-rates/water-financial-plan-fy25.pdf 22 Staff Report 2411-3776 https://cityofpaloalto.primegov.com/api/compilemeetingattachmenthistory/historyattachment/?historyId=35104f06- 6925-4fe3-89c7-b0e53e6eec42; 23 Staff Report 2411-3776, Attachment B, Exhibit 1 FY 2026 Water Utility Financial Forecast and CIP Detail https://www.paloalto.gov/files/assets/public/v/2/agendas-minutes-reports/agendas-minutes/city-council-agendas- minutes/2025/june-16/rates-attachments/finalized-attachment-b-exhibit-1-fy26-water-utility-financial-forecast-and-cip- detail.pdf Item #1     Packet Pg. 22     Staff Report: 2501-4079 – Page 20 of 45 4 Wastewater Utility The Wastewater Utility includes the system of sewer pipes that collect and transport wastewater to the Regional Water Quality Control Plant (RWQCP) operated by the City of Palo Alto under a partnership agreement with several surrounding communities, as well as Palo Alto’s share of the cost of operating the RWQCP. The RWQCP provides treatment and disposal of wastewater for Palo Alto. Costs for the Wastewater Utility are split approximately half for the operation, maintenance and periodic replacement of Palo Alto’s sewer collection system and half for the costs of wastewater treatment at the RWQCP. 4.1 Wastewater Treatment Updates and Capital Planning Status The RWQCP, operated by Palo Alto's Public Works Department, provides wastewater treatment to Palo Alto, Mountain View, Stanford, Los Altos, East Palo Alto, and Los Altos Hills. The Palo Alto Wastewater Collection Utility contributes approximately 37% of the costs (projected for FY 2025). Capital costs, driven by necessary upgrades to aging equipment and changing environmental regulations, are a major factor in cost increases. With plant equipment over 50 years old, significant rehabilitation and replacement are required to maintain safe, compliant wastewater treatment operations. 4.1.1 Treatment Cost Trends RWQCP staff project a 5.5% average annual increase in treatment costs paid by Palo Alto’s Wastewater Utility from FY 2025 to FY 2035. The main drivers are capital projects, materials, and debt service (including loan repayments). Treatment capital expenses, including debt service, are expected to rise by about 30% per year on average to fund equipment replacement and major upgrades. Larger increases in capital expenses are anticipated starting in FY 2030 due to new debt for major projects. The figure below outlines Palo Alto’s share of estimated treatment costs, with upcoming capital projects and planned debt service payments shown in the "Planned Debt Service" bar. Item #1     Packet Pg. 23     Staff Report: 2501-4079 – Page 21 of 45 Figure 16: Palo Alto’s Share of Estimated Wastewater Treatment Expenses (Projection and Planned CIP) The figure above shows annual CIP reinvestment including Existing Debt Service, and pay-as-you-go CIP expenses and also shows treatment operations costs. While operations costs make up the bulk of treatment expenses, they are growing more slowly than planned debt service. The largest increase in planned debt service in FY 2030 is primarily due to the debt service repayments beginning on the Secondary Treatment Upgrades, which is a $193 million capital project to remove nutrients from the wastewater (denitrification) in order to meet upcoming regulatory requirements. Nutrient removal is important to reduce algae blooms that kill fish and other aquatic life. The Secondary Treatment Upgrades project will also replace critical, aging mechanical and electrical equipment. Not included in Figure 17 is the remaining unencumbered and authorized amount for the future pay-as-you-go capital. This amount is estimated to be $3.5 million in FY 2025. The wastewater collection utility needs to hold this amount in reserves until it is needed by the treatment plant. In June 2024, the Council approved a Cost-Sharing Agreement with the Santa Clara Valley Water District for the Guiding Principle 5 grant program, which funds future RWQCP27 projects. The program supports communities like Palo Alto, where taxpayers pay State Water Project property taxes but rely on non-Valley Water supplies for most of their water. Staff estimates a total of $11.2 million in grant funding for Palo Alto’s share of approved RWQCP projects, directly benefiting local customers. Four upcoming projects are eligible for this funding: Outfall Line Construction Headworks Facility Replacement 12kV Electrical Power Distribution Loop Improvements Joint Intercepting Sewer Rehabilitation 27 Staff Report 2404-2877, June 3, 2024 https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=82864 Item #1     Packet Pg. 24     Staff Report: 2501-4079 – Page 22 of 45 4.1.2 Regional Water Quality Control Plant Capital Planning Status The RWQCP continues to undergo significant capital improvements to address aging infrastructure, respond to evolving regulations, and meet future capacity needs. These efforts are guided by the Long-Range Facilities Plan (LRFP), which was originally adopted in 2012 and is now undergoing a comprehensive update, anticipated for completion in 2027. The RWQCP’s current capital work in-progress includes an estimated $495.9 million in projects. The following table summarizes these ongoing projects and provides their status and costs.

The Local Advanced Water Purification System (AWPS) Project, also under construction, aims to reduce salinity in recycled water, enabling expanded non-potable use and supporting future additional reuse efforts. As part of a broader campus-wide approach to meet future space needs, the RWQCP is evaluating the purchase of neighboring properties and, following Council approval of a 20-year lease agreement in May 2025, has initiated design and construction of tenant improvements at a leased facility located at 2470 Embarcadero Way to provide necessary laboratory and office space. The RWQCP plans to fund these capital projects through a combination of mechanisms including pay-as-you-go, State Revolving Fund loans, and revenue bonds. Several sources of funding will be used for the Local AWPS: Valley Water will provide $16 million, Palo Alto was awarded a $12.9 million grant from the United States Bureau of Reclamation’s WaterSMART program, which allocates Title XVI Program funding under the Water Infrastructure Improvements for the Nation (WIIN) Act, and the remaining project costs will be funded through a State Revolving Fund loan along with contributions from the City of Mountain View. The Horizontal Levee Pilot Project is expected to receive funding from the Environmental Protection Agency, Department of Water Resources, Association of Bay Area Governments and the Coastal Conservancy.

Figure 18: Wastewater Sales Revenue ($), FY 2025 4.3.2 Financial Position Treatment costs were higher than forecasted in FY 2023 and FY 2024. Additionally, Palo Alto began Sanitary Sewer Replacement project 31 with an earlier start date in FY 2023 instead of FY 2024. This project was completed in FY 2024. Completing this sewer replacement earlier than previously anticipated was necessary in order to coordinate with Caltrans to limit or avoid digging into newly paved street on El Camino Real. In June 2024, Council approved the FY 2025 Wastewater Collection Financial Plan29 that included a 15% rate increase in FY 2025 and a short-term loan of $3 million from the Fiber Optics Fund Reserve for FY 2024 to cover the cashflow needs of the Wastewater Collection Utility. Although the Wastewater Collection Operations Reserve remained low at the end of FY 2024, the utility’s overall cash balance was $0.34 million due to the $3 million short-term loan. The short-term loan is expected to be paid in FY 2026. Staff expects revenues to cover rising costs in FY 2025 and begin to replenish the utility’s reserves.

Staff anticipates advancing an item for Council consideration in October to take advantage of placing fiber as developments occur citywide. 5.3 Reliability There were no unplanned fiber outages or events to report in Q3 and Q4 of FY 2025. 5.4 Financial Health Below is a summary of the financial position for the fiber utility. Item #1     Packet Pg. 29     Staff Report: 2501-4079 – Page 27 of 45 5.4.1 Fiber Sales Actual dark fiber licensing sales in FY 2025 were $3.7M and $0.2M or 5% above the revenue forecast of $3.5M. The City received a large one-time customer connection fee of $0.2M from Adobe Creek Networks (Staff Report 2407-322735). Adobe Creek Networks is a non-profit founded in 2022 to provide fiber broadband internet to Upper Page Mill Road in Palo Alto, and adjacent areas. Operating fiber expenses were $3.3M and $1.1M or 24% below forecast. The primary cost driver of expenses being below budget is vacancy savings of four open positions. The Fiber Fund added four new positions in FY 2024 to support FTTP. Three of the four new positions are on hold depending on the success and financial sustainability of the FTTP pilot. The City will reassess whether these positions will need to be filled in FY 2026 after staff reports back to UAC and Council with key metrics of the pilot. 5.4.2 Financial Position The ending FY 2024 Fiber Optic Utility Rate Stabilization Reserve is $8 million and an additional $25.5 million of CIP commitments and reappropriations. In addition, the Fiber Fund loaned the Wastewater Collection Fund $3 million in FY 2024. The Wastewater Collection utility will repay the short-term loan in FY 2026 (or sooner) at a rate equal to the City’s portfolio rate plus 0.25%. Based on staff’s forecast, the total reserve for the fiber utility is expected to decline $3M from $33.5 million in FY 2024 to $30.5M in FY 2025 including the $3 million loan to the Wastewater Collection utility. Of the $3 million decrease, $1.5M has been encumbered for construction labor and material for the FTTP pilot. 35 Staff Report 2407-3227: Dark license fiber agreement with Adobe Creek Networks to build dark fiber in the foothills. https://recordsportal.paloalto.gov/Weblink/DocView.aspx?id=83022 Item #1     Packet Pg. 30     Staff Report: 2501-4079 – Page 28 of 45 6 Communications This section summarizes communications highlights, updates on major campaigns and noteworthy events.

Annual Gas Leak Survey: CPAU began the annual walking and mobile gas leak survey of the City. This routine inspection of our gas distribution system is conducted to ensure the safety of all who live and work in Palo Alto. Two types of gas leak surveys are performed every year: a walking survey of half of the residential areas and a mobile survey of all business districts and mains. Approximately one-half of the City is covered every year by the walking survey so the entire gas distribution system can be reviewed in a two-year period. This year the walking survey covers the southern section of Palo Alto. NCPA and NWPPA Federal Policy Conference: Vice Mayor Vicki Veenker and CPAU staff attended the Northern California Power Agency (NCPA) and Northwest Public Power Association (NWPPA) Federal Policy Conference in Washington DC April 28 through May 1. Attendees met with regulators, commissioners, representatives, and staff from various federal agencies to advocate for the interests of NCPA and NWPPA members. CMUA Board of Governors: In May, Palo Alto Utilities was elected to the California Municipal Utilities Association (CMUA) Board of Governors. CMUA advocates for the interests of 84 publicly owned utilities who provide water service to 75% of Californians and electric service capacity to 25% of the state. New Electric Transmission Corridor: On May 22, the California Independent System Operator (CAISO) Board of Governors approved the 2024-2035 Transmission Plan including the NASA Ames to Palo Alto 115 kilovolt (kV) project. This is a major milestone toward establishing a second transmission corridor serving Palo Alto. City Manager Ed Shikada addressed the Board advocating support for the project, as it is critically important to reliability for the entire City of Palo Alto. Audit of Natural Gas Distribution System: The California Public Utilities Commission (CPUC), on behalf of the Federal Department of Transportation, conducted a natural gas safety inspection of CPAU’s natural gas distribution system from May 12 through May 23. The audit included a 3-year (2022-2024) comprehensive review of all gas safety programs and plans, field records of gas pipeline inspections, and the operations of utility field staff. The auditors acknowledged staff’s commitment to operate a safe and reliable natural gas utility with a couple minor recommendations to modify existing procedures. Fred Eyerly Tower Well Park Dedication: Tower Well Park was dedicated and renamed as Fred Eyerly Tower Well Park. Fred Eyerly had a long history of public service for the City of Palo Alto as city council member, mayor, first UAC Chair, NCPA commissioner and commission chair, and acting NCPA manager. He was instrumental in securing key utility resources for Palo Alto such as the Calaveras Hydroelectric Project and water supply from the San Francisco Public Utilities Commission. Annual Consumer Confidence Report: Every year, CPAU produces a consumer confidence report on water quality conditions for the previous calendar year. The 2024 water quality report was published online at paloalto.gov/waterresources in English, Spanish and Traditional Chinese, or in print upon request. Municipal Service Center (MSC) Open House: On July 26, the City hosted an open house at the MSC to showcase the work we do for the community. Nearly 1,000 people attended demonstrations and displays, food trucks, free ice cream, and the opportunity to talk with staff to learn about City services and programs. Program and Event Support: CPAU communications staff provide ongoing annual, monthly, and daily support for outreach to residential and non-residential customers about issues pertaining to sustainability, energy and water efficiency, solar, Item #1     Packet Pg. 31     Staff Report: 2501-4079 – Page 29 of 45 electric vehicles and eBikes, beneficial electrification, capital improvement projects, operations and maintenance, customer service, and technological innovations for utility customers.

The catastrophic LA wildfires in January lent new urgency to addressing wildfire risks and inspired much legislation related to utility wildfire mitigation activity, electricity de-enenergization events (also known as PSPS events), system readiness, and emergency response. Pushes for utility affordability have focused on increased regulatory oversight of utilities, potential changes to regulations that increase consumer costs, permitting and CEQA streamlining, state financing or assistance for electric infrastructure, and establishment of an independent governing board for a new day-ahead wholesale electricity market. Lastly, a more adversarial federal government has moved California lawmakers to try to protect California’s leading clean energy and environmental programs, leading to a reinvigorated push for renewal of the Cap-and-Trade program. CPAU staff met with lawmakers and their staff at NCPA and CMUA’s Capitol Day event in February to advocate for utility affordability measures, Cap-and-Trade reauthorization, and certain considerations for large hydroelectric facilities. Bills of Interest AB 130 (Committee on Budget) | Housing. This bill has been signed into law and limits building code updates at both the state and local level until 2031, negatively impacting the City of Palo Alto’s ability to use building code amendments to meet climate goals. AB 825 (Petrie-Norris) | AB 825 (Petrie-Norris) was amended to replace SB 540 as the vehicle for Pathways legislation to establish a regional day-ahead electricity market and change the language to be more favorable for a successful market. The Governor signed AB 825 into law on September 19th. AB 1273 (Patterson) | Public utilities: ratesetting proceedings: local publicly owned electric utilities: California Renewables Portfolio Standard Program. This bill contains language that would extend publicly owned utilities’ ability to avoid over-procuring renewable energy in years where at least 40% of their electricity sales come from large hydroelectric generation. CPAU strenuously advocated for inclusion of this language and will benefit greatly from its passage. SB 254 (Becker) | Energy. This is the Senate’s utility affordability bill that largely addresses IOU activities but also streamlines POU wildfire mitigation plans (WMP).. It was signed into law by the Governor on September 19th. SB 840/AB 1207 (Limon/Irwin) | Greenhouse gases: report/Climate change: market-based compliance mechanism: price ceiling. These two bills are the Senate and Assembly’s vehicles for reauthorizing the Cap & Trade program beyond 2030 and addressing how funds in the Greenhouse Gas Reduction Fund (GGRF) will be spent. It was signed into law by the Governor on September 19th. 7.2 State Regulatory Activity Regulatory action has been light in the second half of FY25, apart from CARB updating and resubmitting the Low Carbon Fuel Standard (LCFS) amendments. Originally adopted in November 2024, the LCFS amendments were rejected by the Office of Administrative Law (OAL) for administrative reasons including continuity issues and lack of clarity. CARB addressed these deficiencies in a further round of amendments and despite the administrative nature of the updates, CARB delivered an unexpected piece of good news by removing the language that could have taken LCFS credits from utilities and provided them to EV manufacturers. CARB will resubmit the amendments to the OAL where they are expected to be accepted, allowing the regulations to go into effect on July 1, 2025. Item #1     Packet Pg. 33     Staff Report: 2501-4079 – Page 31 of 45 7.3 Federal Activity In recent months, federal administration actions have challenged California and clean energy efforts on a number of fronts. Multiple executive orders made sweeping declarations to legally challenge carbon reduction regulations like Cap-and- Trade and LCFS, bolster the use of fossil fuels, stymie renewable development, and eliminate essential federal staff and programs. Staff reductions at the Bureau of Reclamation (BOR) and the Western Area Power Administration (WAPA) will likely result in an erosion of operational efficiency and safety over time. Tariffs, and their fluctuating nature, have increased equipment prices and their overall instability will likely increase costs for grid-scale projects or cause developers to pull out entirely. Elimination of renewable energy tax credits are further increasing utility costs and are forecasted to reduce additions of electricity generation, while cuts to EV and energy efficiency tax credits are likely to harm the success of CPAU’s numerous utility programs. Item #1     Packet Pg. 34     Staff Report: 2501-4079 – Page 32 of 45 Appendices Item #1     Packet Pg. 35     Staff Report: 2501-4079 – Page 33 of 45 8 Appendix A: Energy Risk Management Program This appendix provides a quarterly update on the City’s Energy Risk Management Program. 8.1 Overview of Hedging Programs The City’s Utilities Department maintains a hedging program for its Electric and Gas Utilities. In the Gas Utility the program protects against short-term (intra-month) price spikes caused by weather or major incidents on the Western gas system. However, the City does not hedge its gas supply more than one month in advance, choosing instead to protect the Gas Utility’s financial position by passing gas supply costs through to customers via a charge that varies monthly based on gas market prices. As a result, the Gas Utility’s only market exposure is the amount by which gas demand deviates from forecasts within the month. This exposure is relatively small and can be managed using Gas Utility Operating Reserves. A risk assessment is performed each year as part of the Gas Utility financial planning process to ensure adequate reserves to cover all risks. The most recent Gas Utility Financial Plan was adopted June 21, 2021 (Staff Report #1224037). The City has entered into long-term contracts for its Electric Utility to ensure that the City has carbon free electricity supplies equal to 100% of Palo Alto’s annual electric demand. However, the output from these generating sources does not match Palo Alto’s electric load. In the summer, the City has a surplus of carbon free energy and it has a deficit in the winter. This exposes the City to market risk, and staff maintains a hedging program to protect against this risk. In addition, hydroelectric generators make up approximately half the City’s energy supply. During dry years these resources do not generate as much energy, creating an additional market exposure that must be hedged. Unlike the gas hedging program, which is operated by City staff, the electric hedging program is operated by the Northern California Power Agency (NCPA), a joint powers agency the City formed in partnership with several other California publicly owned electric utilities, with oversight by City staff. 8.2 Overview of Energy Risk Management Program The hedging programs described above are conducted in accordance with the City’s Energy Risk Management Program, which includes a set of Program Policies adopted by the City Council, Guidelines adopted by the City’s Utilities Risk Oversight Coordinating Committee (UROCC), and Procedures approved by the Utilities Director. In addition, for the electric hedging program, NCPA maintains its own Risk Management Program. The City is able to provide policy level oversight of this program through its seat on the NCPA Risk Oversight Committee, which is held by the City’s Risk Manager. Per the Energy Risk Management Policies, the City Council must receive quarterly reports on the City’s forward contract purchases, market exposure, credit exposure, counterparty credit ratings, transaction compliance, and other relevant data. 8.3 Forward Deals Palo Alto did not execute any Electric or Gas transactions in Q3 and Q4 of FY 2025. 37 Staff Report #12240 https://www.cityofpaloalto.org/files/assets/public/v/3/agendas-minutes-reports/reports/city-manager-reports-cmrs/year- archive/2021/06-21-21-id-12240.pdf Item #1     Packet Pg. 36     Staff Report: 2501-4079 – Page 34 of 45 8.4 Electric Market Exposure The chart below shows the City’s electric supply market exposure and committed purchases and sales to cover exposed positions.

Under CARB’s cap-and-trade rules, Palo Alto must sell all of the allowances freely allocated to the Electric Utility. For the Gas utility, Palo Alto uses some of the freely allocated allowances for greenhouse gas compliance obligations and sells the remaining allowances using the proceeds for the benefit of ratepayers, consistent with AB 32. The City Council approved a policy on the use of freely allocated allowances under the State’s cap-and-trade program (see Resolution 948741 and Reso 1007742). This City policy allows auction proceeds from the sale of Allocated Allowances to be used for renewable energy investments, energy efficiency programs, GHG emissions reduction initiatives, fuel-switching (such as electrification), and ratepayer rebates (with Council approval). Revenues from the sale of allowances freely allocated to the Electric Utility (“electric allowance revenues”) must benefit electric customers only, and similarly, revenues from the sale of allowances freely allocated to the Gas Utility (“gas allowance revenues”) must benefit gas customers. Electric Utility In calendar year (CY) 2024, Palo Alto received 142,536 freely allocated allowances from the State. All of which were sold at state-run auctions, which generated about $5 million in revenue. About $2.47 million was spent on renewable energy purchases to help meet the City’s Renewable Portfolio Standard (RPS) targets. The remaining $2.55 million was transferred to the Electric Cap and Trade reserve to fund future electric greenhouse gas emissions reduction programs. The Electric Cap and Trade reserve has about $4.12 million at the end of FY 2024.

To maintain employee competency with safe working practices, the City provides ten department-wide safety meetings, numerous online training courses and field assessments. During CY2024 employees collectively completed over 1,388 training courses. The City of Palo Alto continues to provide safe and reliable electric service at the lowest reasonable cost. System reliability numbers have improved primarily due to milder winter weather but also due to improvements in restoration processes following an outage. While slowed by the loss of key staff within the metering division, progress continues to complete the AMI project. Currently staff are coordinating across departments to add a new AMI base station atop City Hall providing connectivity and transmission for the downtown district, Stanford campus, and Oak Creek apartments. The base station will allow approximately 3,000 electric meters to be modernized. The Grid Modernization Pilot for the distribution system is completed. The electric infrastructure suppling roughly 908 homes has been upgraded including the replacement of 70 wood utility poles, 106 new transformers, and 22,650 feet of new low-voltage wire. The cost to complete the pilot area reached just over $10 million with contracted labor being the largest cost. Design work continues on necessary upgrades to the Colorado Substation. Recently the City Council approved of a professional services agreement with Burns & McDonnell to support the City in the redesign and replacement of aging infrastructure within the Colorado substation. Staff have begun scoping the work with Burns & McDonnell and expect to have a final high-level assessment of the substation by December of 2025. CY2025 (to-date) Electrification Permit Applications To manage increased load, CPA’s Electric Engineering is responsible for evaluating all electrification-related applications. Figure 1 provides a summary of activity levels across the five main categories. As shown, electrification and the adoption of electric appliances is increasing year over year. Figure 23 – Electrification Permits by Category Between 2019 and 2024, electrification experienced Compound Annual Growth Rates (CAGR) ranging from 12% for EVCS up to 162% for hot water heat pumps. This upward trajectory is anticipated to persist through 2025, as suggested by mid- year performance data.

Staff is briefing the Utilities Advisory Commission (UAC) on preliminary results from the Gas Transition Study to hear questions from the UAC that could inform future work on the analysis and to provide information that could inform 2026 UAC work planning efforts. EXECUTIVE SUMMARY Achieving the community’s greenhouse gas emissions reductions goals requires extensive reductions in building emissions. Regardless of how quickly the community reaches these goals, impacts on the gas utility’s financial structure and physical operations are expected. Staff is studying those impacts. The study will simulate different patterns of electrification throughout Palo Alto, identify opportunities for gas main and service abandonment and operational efficiencies, and estimate abandonment costs, changes in operational costs, and customer class cost allocations. It will prioritize gas system safety and identify parts of the gas system that may need to be retained for operational reasons even after substantial parts of the system have electrified. Staff is sharing preliminary results from the first part of the Gas Transition Study with the UAC so it can adjust course as needed as staff works to complete the study. BACKGROUND Item #2     Packet Pg. 54     Item No. 2. Page 2 of 5 Staff reviewed the methodology for this analysis with the Climate Action and Sustainability Committee (CASC) at its June 13, 2025 meeting1 and with the UAC at its September 3, 2025 meeting.

About 61% of water heating and 50% of space heating equipment in multi-family buildings is estimated to use gas. This aligns with preliminary expectations in the process of community electrification, but these numbers will likely change as results are reviewed in more detail and any data errors or omissions are identified and fixed. Item #2     Packet Pg. 56     Item No. 2. Page 4 of 5 FISCAL/RESOURCE IMPACT 3 (presented at the April 4, 2025 CASC meeting) showed that there are some scenarios in which community benefits from electrification would exceed community costs, including lost gas revenue. Staff and its consultants will complete more detailed estimates of the cost and revenue impacts to the gas utility at various levels of electrification as part of the Gas Transition Study. Staff plans to estimate the cost impacts of various levels of electrification and the impact on various customer classes in the coming months and will return to the UAC and CASC in early 2026 with the results and a list of potential mitigations for any impacts as part of the Gas Transition Study.

Estimated Quantities of Gas Equipment in Single-Family Homes Based on Gas Use Staff’s consultant, Energeia, used anonymized gas usage information from all homes and businesses in Palo Alto to estimate what gas equipment was in the homes. Seasonal usage patterns were used to estimate water heating and space heating gas use. Other data used included home sizes and whether the County Assessor’s data for the parcel noted a pool. Multi-family building equipment was estimated by looking at the combined gas use for the entire building, including the house accounts, to determine whether space and water heating equipment was centrally located or in units and whether that equipment was gas or electric. Equipment in commercial buildings was not estimated, but basic estimates of how much gas was used for space heating vs. water heating were created. Based on that information the following very preliminary estimates for populations of gas equipment were generated. Note that the total number of single-family and multi-family units identified are a bit lower than would be expected based on other sources, indicating the need to review the underlying inputs for missing data. Note that multi- family gas equipment accounts are expected to be significantly lower than the number of multi-family units in Palo Alto, since many apartment units do not have dedicated gas meters, having electric or central gas space heating and central gas water heating.

This item is for discussion only, and no action is requested. EXECUTIVE SUMMARY On September 15, 2025, the City Council approved a voluntary residential electric service time- of-use rate schedule (E-1 TOU), effective January 1, 2026.1 This report summarizes the plan for phased enrollment of the voluntary TOU rate and the communication and marketing plan. The implementation and communication plan is designed to ensure customers are informed, supported, and prepared to successfully transition to TOU rates. Additionally, the communication plan will be designed to inform the community about the new TOU rate option and to convey the beneficial impacts of switching electricity use from the high cost 4 p.m. to 9 p.m. period to the solar electricity generation period of 9 a.m. to 3 p.m. and night time (9 p.m. to 9 a.m.), irrespective of whether the customer elects to be served under the TOU rate. BACKGROUND TOU rates are a type of electricity pricing where the cost of electricity varies depending on the time of day it is used. Under this rate structure, electricity prices are typically lower during off- peak hours, when demand is low, and higher during peak hours, when the grid is under more 1 Staff Report 2505-4750; https://cityofpaloalto.primegov.com/viewer/preview?id=0&type=8&uid=031339b2- 900e-422e-96c0-b5a0be11056b Item #3     Packet Pg. 73     Item No. 3.

These rules are designed to prevent customers from gaming the system and to minimize the administrative burden of switching customers back-and-forth. 5. 6 and reduce strain on the electric grid. Single family customers with the ability to shift loads to super-off peak (solar generation hours) and off-peak hours (night hours) have the greatest potential to benefit from TOU rates. Customers with high electricity consumption can also save by switching to TOU rates7. Multi-family and low-use single-family households are less likely to benefit from switching to TOU rates, as their overall usage is lower and they have limited ability to shift consumption to lower-cost time periods. 5 All the IOUs in California and SMUD have switched all their customers to TOU rate, on an opt-out basis several years ago. When making this switch, which was many years after experimenting with volunteer TOU rate, these utilities made major investment in their customer portals. Their customer portals now display individualized assessments (based on historic hourly consumption data) of comparative customer bills for different rate options. SMUD mailed each customer a letter informing them of the impact TOU rate will have on their bill based on historic consumption patterns. Because of the complex nature of the comparative bill calculations, staff is not aware of any utility providing a customer facing bill comparison calculator. 6 CPAU staff is exploring hosting an individual appliance level relative cost assessment calculator on our website. It would include information at the level of an electric appliance to inform customers about how much money they could save from shifting the time of use of commonly used electrical appliances. An example of a tool like this is the Time-of-Day Cost Estimator from Sacramento Municipal Utilities District. Time-of-Day Cost Estimator. https://www.smud.org/Rate-Information/Residential-rates/Time-of-Day-5-8pm-Rate/Time-of-Day-Cost-Estimator 7 E1 is a tiered rate with customers with a consumption below 450kWh/month enjoying a lower rate of $0.2057/kWh, compared to the higher Tier 2 rate of $0.2294/kWh for consumption above 450kWh. The TOU rates do not have tiers and customers with an average load profile could expect to pay an average rate of $0.215/kWh, which is in between the Tier 1 and Tier 2 rate. Item #3     Packet Pg. 75     Item No. 3. Page 4 of 8 TOU rates will not be immediately available to customers with Solar PV systems, and they are unlikely to benefit from TOU without battery storage capabilities. Due to the lower TOU rates during super off-peak hours of 9 a.m. to 3 p.m. (when solar generation is typically highest), NEM customers will likely receive lower compensation under the TOU structure. NEM1 customers receive full retail credit for excess solar energy exported to the grid. Under TOU rates the NEM1 customers would see lower export credit value and likely higher bills. However, residents with solar and BESS could cycle the battery daily (by charging during solar generation hours and discharging during the 4 p.m. to 9 p.m. peak period) and benefit by switching to TOU rates. Customer Communication and Marketing Plan 11. Outreach will include the City’s website, email, bill inserts, social media, and in-person events. 11 Though Palo Alto’s electric supply is carbon neutral on an annual basis, Palo Alto's marginal electricity source is from the California grid. The state grid’s marginal carbon intensity difference of the electricity produced during solar hours (9 a.m. to 3 p.m.) and non-solar generation hours (3 p.m. to 9 a.m.) is approximately 90lbs of CO2 e/MWh. A typical EV that charges only during solar generation hours, could lower annual emissions associated with the EV's electricity consumption by ~270lbs of CO2/year.

Page 6 of 8 Lessons from other utility case studies suggest that tailored messaging boosts enrollment. Recruitment materials specific to the TOU plan perform better than generic “mass marketing.” Messaging should be direct, simple, and focused on personal financial and environmental impacts. Sharing aggregate customer savings and environmental benefits post-enrollment can sustain engagement and spur word-of-mouth adoption. While TOU rates can lead to cost savings, it's important to monitor customer satisfaction and address any negative impacts. Measures of Success Completion of Testing: Successfully complete the testing process and resolve any identified issues. Program Availability: Making the E-1 TOU rate available to all eligible customers. Customer Satisfaction: Gauging satisfaction among enrolled customers through direct feedback, tracking questions and comments, and reporting on issue resolution. Increased Customer Awareness: Measuring the increase in awareness of the beneficial impacts of switching electricity use from the high cost 4 p.m. to 9 p.m. period to solar electricity generation periods of 9 a.m. to 3 p.m. Customer Behavior Change: Observing measurable shifts in customer energy usage to lower-cost periods among those enrolled in the E-1 TOU rate. Program Impact: Estimating supply cost savings, peak load reduction, and emissions reductions based on observed changes in customer behavior.

This measured approach allows the program to be implemented within current staffing and budget constraints. Item #3     Packet Pg. 79     Item No. 3. Page 8 of 8 STAKEHOLDER ENGAGEMENT At the December 4, 2024, UAC meeting, Staff presented preliminary rate proposals for FY 2026 and provided an update on TOU rates as an informational item for discussion purposes13. On June 4, 2025, staff presented the E-1 TOU rates to the UAC and the UAC unanimously recommended approval of the rates14. On September 2, 2025, staff presented the E-1 TOU rates to the Finance Committee and the Committee unanimously voted to recommend approval to Council. On September 15th the City Council adopted the E-1 TOU rates unanimously. ENVIRONMENTAL REVIEW Discussion of Implementation Plan for Voluntary Residential Electric Service Time-of-Use Rates does not meet the definition of a project under the California Environmental Quality Act (CEQA), pursuant to the California Public Resources Code Section 21065, because it is not an activity that will cause a direct physical change in the environment.

The first goal is to increase opt-in participation from residential customers and maximize customer satisfaction. Since the new TOU rate is voluntary, staff will proactively and effectively market the benefits to customers for a successful outcome. Many customers may not be familiar with the concept of TOU and will need to learn what the rates are and what they mean for their monthly bills. The second goal is to educate all customers about the environmental benefits of consuming electricity during the 9 a.m. to 3 p.m. solar generation periods rather than during the 4 to 9 p.m. peak period. Communication materials will first define what TOU rates are. Traditionally, electric rates have been structured with average electricity prices. Collateral will be developed to explain that this type of rate aligns the changing costs of the electric supply with the rate customers pay, and that depending on supply and demand, electricity costs can change. Outreach materials will explain how TOU works, and the associated rules of the program. CPAU will reinforce that enrolling in TOU is optional, and to ease customer anxieties about trying something new, that there are no penalties for returning to standard rates. However, once a customer switches to TOU, they must stay on the rate for a minimum of six (6) months). To aid in the communication, outreach messaging may include common analogies to help explain how TOU rates compare to traditional rates. For example, TOU rates can be likened to supply and demand basics. When supplies are short and demand is high, the cost can go up. Additionally, consumers often change when they purchase items to take advantage of discounts or sales and save money. It will be helpful to provide examples of popular household items (washing machines, dishwashers, televisions, etc.) that may go on sale at certain times to compare an estimated price during peak and off-peak hours. CPAU will focus on customer-centric messaging in outreach materials, highlighting the benefits of a TOU rate for customers. TOU rates can help customers save money by shifting usage to off- peak hours and gain greater control over their utility bills, particularly for high-energy using appliances. Outreach messaging and graphic design will convey these potential savings to customers as an incentive to opt-in to the TOU rate. Messaging will also highlight that, whether a customer opts in to the TOU rate or not, shifting usage way from peak hours will contribute to a cleaner environment by supporting grid stability and renewables integration. See attachment C for drafts of potential marketing messaging that can be used across a variety of communication channels.

Item #3     Packet Pg. 82     8 9 2 8 customer-centric decision-making, and ultimately supports TOU participation growth and a stronger brand reputation. Customer survey questions will address issues of awareness, understanding, reasons for opting in to a TOU rate, ease of access and enrollment process, ability to shift energy use activities, realized benefits from shifting energy use and being on TOU, and overall satisfaction of being on a TOU rate structure.

How is it different from my current billing rate? A Time-of-Use (TOU) rate is a type of utility billing arrangement in which the amount you pay for electricity changes based on the time of day you use electricity. With the current residential electric billing (E-1) rate, you pay the same amount for electricity regardless of the time of day you use it. Your billing rate increases after you use a certain amount of electricity each month, which is called tiered pricing. With the TOU rate (E-1 TOU), your electric rate changes based on when you use power: Highest rates: 4 p.m. to 9 p.m. (peak-hours) Lowest rates: 9 a.m. to 3 p.m. (super-off-peak hours) Mid-range rates: All other times (off-peak) E-1 (Tier 1 and Tier 2) and Summer E-1 TOU Rate for Fiscal Year (FY) 2026 E-1 (Tier 1 and Tier 2) and Winter E-1 TOU Rate for Fiscal Year (FY) 2026 Item #3     Packet Pg. 87     9 2 3 7 How can I save money by switching to TOU rates? Charge your electric vehicle (EV) between 9 a.m. to 3 p.m. and not during peak hours from 4 p.m. to 9 p.m. Charge your battery between 9 a.m. and 3 p.m. and discharge it between 4 p.m. and 9 p.m. Pre-cool your home in the summer before 4 p.m. Start or program large appliances like your dishwasher, washing machine or clothes dryer to run and finish before 4 p.m. or start after 9 p.m. If you have an electric heat pump water heater or space heating system, observe when they are turning on and try to adjust your heating needs to off-peak periods. If you have programmable smart appliances or smart electric panels, program them for optimal use of appliances. : Have an electric vehicle (EV) or plan to get one. Have a battery energy storage system (BESS) or plan to get one. Can shift major electricity use between 9 a.m. to 3 p.m. and away from 4 p.m. to 9 p.m. Want to support the use of clean energy and grid decarbonization. Consume higher amounts of electricity, typically more than 600 to 800 kilowatt hours (kWh) per month. Use lower amounts of electricity, typically less than 600 kWh per month. Cannot adjust the times when electricity is used to off-peak hours. Prefer uniform pricing every hour of the day.

Item #3     Packet Pg. 88     9 2 3 7 Your bill impact under a TOU rate structure depends on how much you are able to adjust what time of day you use electricity. The more you are able to use electricity during the less expensive solar generation hours of 9 a.m. to 3 p.m., the more you can save on your monthly utility bill.

EXECUTIVE SUMMARY In August 2020, the City Council approved amendments to the electric utility’s Carbon Neutral Plan that clarified and modified policies regarding the sales and exchanges of renewable energy credits (RECs) (Staff Report 115561). The amendments permitted the exchange of Bucket 1 (primarily in-state) RECs for Bucket 3 (primarily out-of-state) RECs, provided the City maintains compliance with State Renewable Portfolio Standard (RPS) regulations. A portion of the earnings from the program were directed to be used to offset electric operational costs and mitigate the economic impacts of the coronavirus pandemic, and the remainder were reserved for local decarbonization programs. Since then, staff has purchased and sold RECs for Calendar Years (CYs) 1 Staff Report 11556: https://www.paloalto.gov/files/assets/public/v/1/agendas-minutes-reports/reports/city- manager-reports-cmrs/year-archive/2020-2/id-11566.pdf Item #4     Packet Pg. 112     Item No. 4.

The City has achieved its Carbon Neutral Plan objectives each year starting in 2013, and due to its pursuit of these objectives, the City’s electric supply portfolio currently easily exceeds the state’s Renewable Portfolio Standard (RPS) procurement requirements. 5 to take advantage of the significant cost difference between Bucket 1 and Bucket 3 RECs6 to generate additional revenue for the City’s electric utility and to fund local decarbonization initiatives (Resolution 99137, Staff Report 115568). The Council directed that for 2020 and 2021, two-thirds of the proceeds from this program would go to electric operating cost reductions and one-third toward local GHG emission reduction programs, and that for 2022 onward all of the earnings would be devoted to emission reduction programs9. 3 These funds have been set aside for future local decarbonization spending, but to date the funding for these efforts has come solely from Public Benefits funds, Low Carbon Fuel Standard revenues, and Gas Cap & Trade allowance revenues. 4 Resolution 9322: https://www.paloalto.gov/files/assets/public/v/1/city-clerk/resolutions/reso-9322-33835.pdf 5 The exchange of bundled RECs from the City’s in-state, long-term renewable resources (Bucket 1 RECs) for RPS- eligible, unbundled RECs (Bucket 3 RECs), which usually come from out of state sources. 6 Due to limitations on the use of Bucket 3 RECs for compliance with the state’s RPS mandate (only 10% of a utility’s RPS procurement may consist of Bucket 3 RECs), a significant financial premium currently exists for in-state bundled renewable energy resources (Bucket 1 RECs). 7 Resolution 9913: https://www.paloalto.gov/files/assets/public/v/1/city-clerk/resolutions/reso- 9913.pdf?t=40151.26 8 Staff Report 11556: https://www.paloalto.gov/files/assets/public/v/1/agendas-minutes-reports/reports/city- manager-reports-cmrs/year-archive/2020-2/id-11566.pdf 9 The exact funding mechanism for the local decarbonization spending is that an amount equivalent to at least one- third of the revenues earned from the REC Exchanges would be allocated from the City’s Cap and Trade Reserve to local decarbonization efforts. Item #4     Packet Pg. 113     Item No. 4. Page 3 of 7 8 2 4 9 In December 2022, the City Council reviewed the results of the REC Exchange Program and voted to reauthorize it. They also directed staff to return to the UAC and City Council in 2025 to provide another review of the program’s impacts, which is the subject of this report. ANALYSIS Carbon Neutral Plan Review annual accounting of the City’s load and its carbon neutral electric resources: an electric supply portfolio with “annual net zero greenhouse gas (GHG) emissions, measured at the Citygate, in accordance with The Climate Registry’s Electric Power Sector protocol for GHG emissions measurement and reporting.” At the time this definition was adopted, this was the most granular accounting approach feasible (given the lack of hourly grid emissions data) or necessary (given the small amount of solar capacity installed at that point, and the resulting emissions profile of grid electricity). hourly carbon emissions accounting standard. This modification was made because: (a) hourly grid emissions data had recently become available, and (b) the large volume of solar generation on the grid at that point had yielded a wide variation in grid emissions intensities over the course of the year and any given day. REC Exchange Program Results (2020-2025) and Projections (2026-2030) 17 These REC Exchange transactions have yielded a total of $28.7 million in net revenue, or about $4.78 million per year. 17 Staff has purchased additional Bucket 3 RECs and sold additional Bucket 1 RECs during this time period (96,198 additional RECs purchased and 49,814 additional sold); however, these are RECs that would have been bought or sold anyway. The Bucket 3 REC purchases were needed to satisfy the City’s Carbon Neutral Plan goals during a drought period (in 2021 and 2022), and the Bucket 1 RECs were sold because the City had an overall surplus of such supplies relative to its RPS procurement requirements. The analysis in this report includes only the REC transactions that were the direct result of the approval of the REC Exchange Program. Item #4     Packet Pg. 114     Item No. 4.

Actual net revenues have thus far come in significantly higher than this initial estimate, largely due to a huge spike in Bucket 1 REC prices that occurred in 2023 and 2024. Over the next five years, staff estimates that the program will yield approximately $9.5 million in total net revenue, or $1.9 million per year, as shown in Table 2 below. The REC Exchange Program’s earnings are projected to decline sharply in future years, primarily due to the ramping up of the state’s RPS requirement levels, which reduces the volume of Bucket 1 supplies the City is able to sell. In addition, the City has begun to experience load growth in recent years (including a 12% increase from 2022 to 2024), and some of the City’s older renewable energy contracts are set to expire in the coming years; both factors further reduce the volume of Bucket 1 supplies available to exchange. 155,000 177,000 130,000 48,000 8,000 3.87 4.43 3.25 1.20 0.19 0.93 1.15 0.91 0.36 0.06 2.94 3.28 2.34 0.84 0.13 50%52%55%57%60% 19 The volume of PCC1 RECs that are sold and the volume of PCC3 RECs that are purchased, pursuant to the REC Exchange Program.

Page 5 of 7 8 2 4 9 Impact on Palo Alto’s Supply Portfolio As discussed in Staff Report 1155621, although exchanging in-state RECs for out-of-state RECs has no real impact on the City’s total electricity-related carbon emissions, the downside of this strategy is that it has a negative impact on the City’s reported portfolio make-up and carbon emissions. California’s RPS law gives preferential treatment to in-state renewable resources over out-of-state resources, and the same is true of how such resources are reported to customers on the annual Power Content Label (PCL). The California Energy Commission’s (CEC’s) PCL regulations require that utilities report their out-of-state (Bucket 3) REC purchases as “unspecified sources of power” rather than under the appropriate renewable energy technology category. Furthermore, utilities are now required to report the annual average GHG emissions intensity of their electric supply on their PCLs—and again, rather than being treated as carbon- free resources like other forms of renewable energy, Bucket 3 RECs are treated as having an emissions intensity equivalent to generic market power purchases (944 lbs of CO2 per MWh, which is almost 20% greater than the average emissions intensity of natural gas generation). As a result, rather than reporting a supply mix that is over 60% renewable and nearly carbon-free,22 under the REC Exchange Program the City must report a portfolio mix that is less than 40% renewable and is responsible for a moderate amount of carbon emissions. Figure 1 below depicts the City’s projected electric supply portfolio mix in CY 2025, before and after accounting for the REC Exchange Program transactions. Meanwhile, the estimated annual average GHG emissions intensities that the City would report on its PCL for these two portfolios are 45 and 159 lbs CO2 per MWh, respectively.23 21 Staff Report 11556: https://www.paloalto.gov/files/assets/public/v/1/agendas-minutes-reports/reports/city- manager-reports-cmrs/year-archive/2020-2/id-11566.pdf 22 Although the City’s baseline portfolio mix is entirely comprised of renewables and hydroelectric resources, the CEC’s PCL regulations assign a small emission intensity to all biomass generation such as landfill gas generation, which currently accounts for about 9% of the City’s baseline electric supply mix. 23 For reference, the statewide average GHG emissions intensity for CY 2024 was 359 lbs CO2 per MWh, while the City’s average GHG emissions intensity as reported on its PCL (and accounting for the REC Exchange Program transactions) was 21 lbs CO2 per MWh. The City’s emissions intensity is projected to be higher for CY 2025 than for CY 2024 because of a significant decline in hydroelectric generation this year.

Page 6 of 7 8 2 4 9 Figure 1: Projected Electric Supplies in CY 2025, with and without REC Exchange Transactions Use of REC Exchange Funds Of the $28.65 million in net revenue that the REC Exchange Program has brought in since 2020, $3.35 million of it has been directed towards general electric operating cost reductions (in accordance with Council’s direction that two-thirds of the net proceeds should be used in this way for 2020 and 2021, to offset the impacts of the pandemic) and the remaining $25.3 million has been set aside for future spending on local decarbonization programs.27 If the recommendation to continue the REC Exchange Program is approved, all of the net revenue from the program (whose estimates are shown in Table 2) would be used for these decarbonization efforts. To date, the programs that this funding has supported include the advanced heat-pump water heater (HPWH) pilot, the Home Efficiency Genie program, and multi-family building electrification efforts. Upon the approval of the recommendation, staff will continue to execute transactions to sell the City’s in-state renewable resources and purchase out-of-state renewables for 2026 and beyond. 27 Again, the mechanism for funding the local decarbonization programs is that an amount equivalent to the net revenues earned from the REC Exchanges would be allocated from the City’s Cap and Trade Reserve to local decarbonization efforts. Although, if the REC Exchange Program’s net revenues exceed the revenues from selling the electric utility’s Cap and Trade allowances in a given year, the local decarbonization funding allocation would be limited by the Cap and Trade allowance revenue amount.
