UTILITIES DIRECTOR REPORT
Kiely Nose, Interim Director of Utilities, delivered the Director's Report.
On January 25, 2025, the City Council held its annual retreat to select their priorities for 2025 as
well as review community input and key accomplishments for 2024. Council established the
following four priorities: Implement housing strategies for social and economic balance, climate
action and adaptation, natural environment protection, economic development and retail
vibrancy; and public safety, wellness, and belonging. The Council approved the formation of the
Utilities Advisory Commission Minutes Approved on: Page 2 of 29
following four committees for the 2025 calendar year: Climate Action and Sustainability
Committee, Retail Committee, Rail Committee, and Cubberley. On February 24, 2025, the
Council will discuss the objectives, projects, and work plans associated with their four priorities
as well as the scope of the ad hoc committees. After February 24, 2025, committees and
commissions will work on their 2025 work plans. The UAC’s 2025 work plan will go to Council
for approval in March or April.

ITEM 2: DISCUSSION: Reliability and Resiliency Strategic Plan: Update on Studies
Utilities Advisory Commission Minutes Approved on: Page 3 of 29
Karla Dailey, Assistant Director of Utilities Resource Management Division, addressed the UAC.
The Reliability and Resiliency Strategic Plan (RRSP) was a collaboration between Utilities,
Engineering, and Resource Management and was part of a larger interdepartmental team led
by Jonathan Abendschein, Assistant Director of Climate Action. The Utilities leads on this part of
the project were Shiva Swaminathan from Resource Management and Mohammad Fattah from
Engineering. The RRSP goal was to improve reliability and resiliency for the community via
upgrading distribution equipment and strategies such as distributed energy resources. Council
approved the RRSP in April of 2024. In the fall of 2024, staff came to the UAC to obtain
feedback on the scope for consultants. Staff returned today to provide an update per the UAC’s
request and to request feedback on parts of the RRSP.

those technologies could contribute benefit to the community. In September, staff was asked
whether energy efficiency could be included. Staff considered the idea but felt it was
duplicative to have Buro Happold analyze energy efficiency because CPAU partnered with other
publicly owned utilities (POU) throughout the California Municipal Utilities Association to do a
study on energy efficiency measures.

Commissioner Tucher looked in September and December’s meeting materials and was unable
to easily find if an assessment has been performed to identify areas of weakness in reliability
and resiliency. Mr. Abendschein said the grid modernization study was a basic assessment that
identified areas needing work. Mr. Abendschein suggested watching the February 2024 Council
Study Session on reliability. Commissioner Tucher hoped to find a map showing the trouble
areas in Palo Alto or a document explaining how reliability and resiliency were assessed and
what the weak points were. Commissioner Tucher thought the grid was resilient, Palo Alto did
not have a lot of outages, the duration of outages was not bad, and customers were generally
satisfied. Mr. Abendschein encouraged Commissioner Tucher to email him so staff could share
further information.
Relative to the S/CAP and the list of technologies, Commissioner Phillips asked if climate change
impact was considered or if it would be looked at separately. Mr. Abendschein explained that
the carbon impact was integrated into the supply cost analysis because markets were
structured in California to have high costs when carbon emissions were high, so the supply cost
included the carbon benefits on the grid in avoided gas generation. Commissioner Phillips asked
if the cost was high because the marginal cost of gas generation was a proxy for or equaled the
cost we would assign to the carbon emission. Mr. Abendschein stated that the market cost of
carbon was included but staff will take Commissioner Phillips’s comment into consideration
when looking at the supply cost analysis. When staff comes back to the UAC, they will address
the question on whether a higher carbon cost should be allocated to avoided gas generation in
the electric system.
On Slide 5, Commissioner Phillips was surprised to see time-of-use rates and demand response
did not impact resiliency because he thought it would make the system more resilient. Outages
tend to happen at certain times of the day because of peaking, so charging higher prices for
that time of day would dampen local demand and possibly cause industrial to shift away from
those times to reduce the impact. Commercial was 85 percent of the load. Mr. Abendschein
clarified that the resiliency column on Slide 5 was about what happened when an outage
occurred. Demand response indirectly could contribute to reductions in outages, so it
qualitatively improved reliability and resiliency of the system.
Commissioner Gupta asked if the assessment of the technologies listed on Slide 5 might inform
how we approach grid modernization. Commissioner Gupta recalled a member of the public
commented about using meter socket adaptors as a means of reducing the need to increase
the capacity to a home because it bifurcated the circuit from your electric vehicle (EV) and the
rest of your house. Mr. Abendschein replied that meter socket adaptors would be talked about
in Buro Happold’s presentation. The E3 analysis was to assess whether technologies or efficient
electrification could allow for changes in the grid modernization implementation, which would
be talked about in depth in Item 2C.
Commissioner Gupta asked for definitions of the technologies listed on Slide 5. Mr.
Abendschein responded that EV managed charging was a technology used to limit the
Utilities Advisory Commission Minutes Approved on: Page 6 of 29
maximum draw from the distribution system at any one time. Demand response was when
people stopped EV charging in response to grid events. Vehicle to home was the ability to back
up a home using a vehicle. Vehicle to grid was the ability to have your EV discharge or charge in
response to grid signals.

Commissioner Croft asked whether staff had looked at all the grids in Palo Alto, such as energy
generators and arrays on schools. Commissioner Croft looked on Google Maps to see which
companies or buildings had big solar arrays. Commissioner Croft inquired if there had been any
consideration to negotiating with the owners of those arrays to have them be a backup source
of energy to the City or perhaps connected to storage as part of the resiliency plan. Mr.
Abendschein made note of Commissioner Croft’s comment for staff to consider.
ITEM 2A: DISCUSSION: Supply and Resiliency Cost/Benefit Analysis and Program Ideas
Utilities Advisory Commission Minutes Approved on: Page 8 of 29
Commissioner Metz asked about capacity cost, RA cost, and other CPAU costs. Mr. Miramontes
replied that the cost per megawatt hour encompassed transmission and distribution but he
thought the RA was built in. Mr. Miramontes offered to follow up with the exact parameters
included. Commissioner Metz was interested in the financial cost beyond the kilowatt hour
energy cost and the benefits beyond financial benefits. Mr. Abendschein explained that supply
costs included energy costs and a renewable energy dimension, a greenhouse gas cost, losses,
as well as transmission, distribution, and generating capacity, which were costs based on
needing to meet a peak. Transmission was charged to Palo Alto on a kilowatt hour basis and
spread across the year, so the summer peak was not as steep as the statewide model. Palo Alto
buys generating capacity that other utilities do not need. Palo Alto does not build and own
large, new generators. Other utilities may put the cost of new generation into their peak
capacity value; however, that is not an economic value we can realize in Palo Alto. Statewide,
the zero value on the chart due to new generation was hours of solar over-generation. The
City’s avoided cost model did not show a zero cost because we pay to transmit energy and
transmission is on an hourly basis.
Commissioner Phillips inquired if it was possible to arbitrage, which would also capture some of
the social value. Mr. Abendschein will get back to Commissioner Phillips with a response. Shiva
Swaminathan, Senior Resource Planner, explained the disparity was primarily driven by
transmission constraints and the State needing to invest in transmission. Transmission capacity
was embedded into an easy-to-model framework but energy arbitrage was on an energy basis.
You cannot arbitrage capacity in the market. The difference was due to transmission and
generation capacity, not the energy component alone. Adding generation capacity through
technologies could avoid Utility costs. Palo Alto sells surplus generation into the market to
make money but has to buy from the market at a higher price when we are short. The capacity
was a transparent market. Mr. Abendschein remarked that the State’s valuation model looked
at the cost of building a new transmission line or generator, which was more costly than the
market value of capacity. Almost never was the price of building a new transmission line or
generator reflected in the market, so it made arbitrage difficult. Mr. Swaminathan agreed with
Mr. Abendschein’s explanation and added that the modeled results were for 2025, 2030, 2035,
2040, and 2045, which included new capacity needing to come online.
Vice Chair Mauter asked if it was the marginal cost of acquiring a new unit. Mr. Abendschein
answered yes for the long-term marginal cost, although the marginal price was not always
reflected in the market. Vice Chair Mauter thought it might help for the Commission to know
that this did not include local distribution avoided cost. For example, there could be a citywide
variation in costs for a microgrid. Mr. Abendschein agreed and stated that the set of studies
would capture supply, distribution, and resiliency benefits.
Commissioner Croft queried what was the difference between 2025 and 2030, and if batteries
coming online would reduce the statewide peak. Mr. Abendschein replied that the disparity
would remain but would probably change. Mr. Miramontes remarked that in the 2035 and
2040 models, the peaks tended to shift further toward nighttime hours likely due to more EV
Utilities Advisory Commission Minutes Approved on: Page 9 of 29
charging on the grid, so the pricing reflected additional demand. Different load shapes were
presented in the forecasted years. The modeling process incorporated technologies when
reflecting the current and future state of the grid and pricing structure. Mr. Abendschein asked
whether the divergence between the Palo Alto and statewide models narrowed, widened, or
stayed about the same. Mr. Miramontes thought it stayed about the same. Commissioner Metz
commented that Palo Alto had a diurnal load profile that peaked earlier in the day than other
parts of the state on average. Palo Alto could sell energy. Mr. Abendschein stated that Palo Alto
had generation from hydro to put into evening hours.

On a scale from 1 to 10, Commissioner Gupta wanted to know the confidence level on the
assumptions made about costs, which would be helpful for the Commission to keep in mind
when assessing the benefits of these technologies at a later stage. Mr. Abendschein stated that
all inputs were reviewed, staff provided a lot of the inputs, and these were the best estimates
but there was always uncertainty. A change in market conditions could change the cost/benefit
assessment. Because of uncertainty, the quantitative analysis was not meant to be the only
consideration when deciding whether to run these programs.

sector referred to low-probability, high-consequence, disruptive impacts with a duration of
hours to months, often had a much wider scale of regional or statewide impact, and often had
cascading impacts in other parts of the economy. For this study, the scope was focused on
outages in the range of two to eight hours, and the technologies typically provided outage
prevention within 24 hours.

improve data accuracy. Depending on when it is released, Buro Happold can easily update it in
their model.

however, the data in the current model was not recent. Commissioner Phillips asked for a list of
what was included, such as if median income was split between residential and commercial.

much higher value of resiliency. Chair Scharff commented some qualitative benefits were
comfort, the ability to take a shower and flush your toilet if you do not have electricity.

The C40 studies were quantitative but addressed financial and sustainability impacts.
Commissioner Metz recommended evaluating resilience using a scenario approach starting with
business as usual, a normal interruption from minutes or hours, and an emergency such as an
earthquake with days or weeks of disruptive interruption. The analysis of emergencies needed
to be coordinated with the Office of Emergency Services (OES). Commissioner Metz and
Commissioner Gupta had some discussions with Ken Dueker and other folks at the OES. The
OES had strong and well-informed opinions about design emergencies we should be preparing
for and Commissioner Metz did not see those reflected in this study. Commissioner Metz
believed it was important for CPAU and the City to coordinate its definition of and preparation
for an emergency with the OES.

as low probability and the strategic plan was called Reliability and Resiliency yet it would not
study resilience in that context.

found across the state. Programs with a component for Disadvantaged Communities (DACs)
were denoted, such as higher incentive rates for low-income customers or customers residing
in a DAC-designated area. The most common amongst Palo Alto’s peers was battery programs.
This research will be used to inform program design.
ACTION: None.

could be done as a behind-the-meter system, which he did not think was common when
crossing parcels, so a Utility Power Purchase Agreement (PPA) was probably more appropriate
for crossing parcels. Commissioner Tucher asked if staff was contemplating going to a partner
or customer and saying the City wanted to install a microgrid for you. Mr. Abendschein stated
that in Commissioner Tucher’s scenario it would be used fulfill part of the City’s energy
portfolio.

outage and being able to run critical loads for a longer period. Mr. Abendschein stated he was
told by Shiva Swaminathan that the airport did not have backup generation.

clear on their position on microgrids. Mr. Abendschein replied that a microgrid was a
combination of generation and loads that can run off-grid for some period of time. One house,
a small commercial building, and a campus can be run as a microgrid but Stanford University
was not. Mr. Abendschein thought there were maybe one or two microgrids in Palo Alto but he
was not aware of campuses or large facilities in Palo Alto being run as microgrids. Customers
can have a microgrid but CPAU had connection rules and regulations. CPAU did not have a
position for or against microgrids.

Abendschein replied that after the study was completed, they will tell the UAC the economics
and whether it made sense. Chair Scharff was convinced cheaper EV charging could be done by
using garages with solar panels so people can charge in an emergency.

delay using the available diesel through the use of solar and storage, although it had to provide
other economic benefits.

Mayor Lauing, UAC Liaison, addressed Commissioner Tucher’s question about policies. There
were no policies in most cases, which was why the UAC and staff were working on this. There
were not a lot of climate policies in place, so the Climate Action Committee was working on
creating policies, programs, and financing for everything that has to be done. Commissioner
Tucher asked for an example of a microgrid policy. Mayor Lauing replied that they had a neutral
policy but an example of a policy could be to actively subsidize microgrids or an incentive
program to promote microgrids with a goal to have X number of microgrids or X megawatt
capacity through microgrids built within a specified amount of time. Some of this will be
addressed through the S/CAP committee to Council as well.
ACTION: None.

our website and through our Qmerit service that helps people find contractors to install EV
charging.

not guaranteed because it depended on staff’s time and the UAC’s agenda. Staff planned to
present fiber rates and packages, and provide the UAC an opportunity to ask questions about
fiber-to-the-premise. It was a three-month process to go from the UAC to the Finance
Committee and then to Council. The goal was to have it done this fiscal year. The soonest that
rates could be adopted by the Council was June of 2025, which meant a program would be
instituted the following month. As part of the discussion with the UAC, staff will provide a
broader and more firm response on the timing.

send a copy of Commissioner Tucher’s letter to the UAC and include it in the next UAC package.
Chair Scharff stated there could be an agenda item about whether the UAC wanted to agendize
it. Commissioner Croft pointed out there were four raised hands in response to the straw poll.
Commissioner Metz verbally stated he would like to agendize the letter. It was the consensus of
the Commission, so Chair Scharff asked staff to agendize it.
