Utilities Advisory Commission
Staff Report
From: Dean Batchelor, Director Utilities
Lead Department: Utilities
Meeting Date: January 3, 2024
Staff Report : 2309-2080
TITLE
Discussion and Update on the Fiscal Year 2025 Preliminary Utilities Financial Forecast and Rate
Projections
RECOMMENDATIONS
This item is for discussion and no action is requested. Staff seeks input from the Utilities Advisory
Commission (UAC) on its preliminary rate projections for the Electric, Gas, Water and Wastewater
Collection utilities to guide and update its recommended FY 2025 Financial Plans and proposed
rate changes.
The attached presentation describes staff’s preliminary rate projections for the various utilities;
staff will continue to update and refine these estimates in light of changing economic conditions
and supply trends, in order to ensure continued cost-based rate offerings. Staff plans to return
to the UAC with proposed Financial Plans, and rates in March of 2024.

PRELIMINARY SYSTEM AVERAGE RATE PROJECTIONS
1)-5% change includes a 21% increase to base electric rates and removal of the hydro rate adjuster
2)Based on general fund transfer of 11.9% of gross revenue in FY25; gas rate changes shown with commodity rates held constant;
actual gas commodity rates vary monthly
3)Storm Drain fees increase by CPI index annually per approved 2017 ballot measure
4)Based on an FY 2023 monthly residential bill of $369

ONGOING COST CONTAINMENT
•Consistent with the Utilities Strategic Plan, cost containment
is being instituted as an ongoing priority and annual cycle
•Winter completion of preliminary out-year rate forecasts
•Review by all Divisions for alignment of multiyear strategies
•Ongoing management review of personnel actions
•Review/revision of position classifications to match evolving needs
•Addition/Deletion of positions to reflect organizational priorities
•Review/approval to fill individual position vacancies in conjunction
with ASD Budget Office and Human Resources
•Regular review of performance metrics and expenditures
4
RECENTLY IMPLEMENTED COST CONTAINMENT
•Agreement with Valley Water: $250K to $1M/year + up to $16 million in funding for
reverse osmosis facility to improve recycled water quality
•Selling surplus Resource Adequacy and RECs ($20+ million/year)
•Negotiated improvements to Western hydroelectric contract ($2 million/year)
•Established a cross-functional field crew to install water, gas, and sewer services
simultaneously at new construction sites, reducing hours spent in the field; staff
time freed up to be reallocated to sewer replacements
•Implemented mobile workforce applications, reducing administrative data entry
time, freeing up staff for other work
•Scheduled larger CIP projects every other year to achieve efficiencies in project
management and also better bids / lower construction costs
•Expanding use of bank draft to reduce credit card fees, particularly for large accounts
•BAWSCA water bond refunding to achieve lower debt service payments for
wholesale customers, including Palo Alto beginning in 2023
5
FUTURE POTENTIAL COST CONTAINMENT
•Switch to new customer information system with reduced support costs
•Explore prepay of renewable power purchase agreements to monetize municipal tax
-exempt debt
•Negotiating layoff of transmission asset to better monetize resource
•Increased water and energy end use technical training for Customer Service
Representatives, reducing transferred phone calls and staff time
•Working to cluster gas main replacements to reduce mobilization costs for
construction contractors
•Evaluating in-house (rather than contractor) pipeline materials procurement to
reduce construction markups

FY 2025 proposal:
•5% overall increase
•Reserves recovering from 2020-2022 drawdown
•Planned repayment to Hydroelectric Rate Stabilization and Electric Special Projects
Reserves will reduce Operations Reserves below minimum levels
•Net supply costs forecast to decline from improved hydro conditions and lower natural gas
prices
•Revenues from surplus system Resource Adequacy and Renewable Energy Certificates
further reducing supply costs
Future years:
•2-4% rate increase in FY 2026-FY 2029
•Issue debt for Grid Modernization by end of FY24 with debt service starting in FY 2025

Supply Cost Drivers
•Record high load costs in FY23, double prior 4-year average
•Surplus Resource Adequacy reducing power supply costs by
$14.4 million in FY25
•Surplus Renewable Energy Credits reducing power supply
costs by $7.6 million in FY25
•Higher hydroelectric generation projections reduced
projected supply costs by nearly $4.7 million in FY24
•Transmission costs remain high – still waiting on transmission
rate case resolution, refund, and lower rates
•Geothermal Power Purchase Agreement starting 2025,
Western Base Resource costs reduced slightly
13
Distribution Cost Drivers
•Inflation
•Medical/retirement benefit costs and associated overhead
costs continue to increase
•Increased capital investment in the electric distribution
system needed due to system age
•Grid Modernization, which is currently assumed to be bond
financed
•Underground construction costs have increased substantially
•Additional contract expense for line crew until internally
staffed

Gas Utility Basics
City of Palo Alto gas distribution system:
•20,000 meters
•205 miles of mains
•18,000 service lines
23
•About one-third to two-third of the rate is
“supply-related:” gas supply, transmission,
and environmental charges. These rates
vary monthly according to market-driven
costs that are passed directly to
customers
•The remaining portion of the rate is set
based on the City’s costs for maintaining
its gas distribution system (gas mains,
services, related equipment). These rates
are being discussed here tonight.
