UTILITIES DIRECTOR REPORT
1. Bay Area SunShares Solar PV & Zero-Emissions Vehicle Program
This is the last month to sign up for the Bay Area SunShares program, which offers
discounted rates on solar PV systems and zero-emissions vehicles. By harnessing the bulk
buying power of homeowners and vehicle buyers, SunShares aims to make it simpler and
cheaper to go solar or purchase a zero-emissions vehicle. Participation is open to residents
and employees of companies located in any of the nine Bay Area counties, as well as Yolo
and Sacramento counties. The last day to join is November 4. Details and registration are
available at cityofpaloalto.org/SunShares or bayareasunshares.org
2. No Better Time to Go Solar!
With Council direction to revise the method to calculate the Net Energy Metering (NEM)
cap, Palo Alto’s NEM cap increased 13% from 9.5 megawatts (MW) to 10.8 MW. Solar
customers can still take advantage of the NEM rate, which offers full retail value for their
solar production, before the program closes. The City could reach the new NEM cap within
the next six months, after which new solar customers will be placed on the NEM Successor

rate. The expansion of the NEM cap and the availability of the SunShares program make
now the best time to go solar! Information on Palo Alto’s solar programs is available at
cityofpaloalto.org/solar
3. Georgetown University Energy Prize Competition
The City continues its participation in the Georgetown University Energy Prize competition
which culminates at the end of December 2016. Utilities is collaborating with the Palo Alto
Unified School District to develop programs designed to engage residential customers. At
the core of the programs is CPAU’s new Utility Portal, an online tool that enables customers
to learn about their energy and water use, efficiency measures and tips to reduce usage. In
order to increase Portal engagement, Utilities is developing an Energy Passport initiative for
elementary schools, as well as a Portal Sign-Up campaign for middle schools and high
schools. PAUSD is also connecting its curriculum with the real-life information on energy
and water use. More at www.cityofpaloalto.org/georgetown

UNFINISHED BUSINESS
1. Selection of Potential topics for the Joint Study Session with Council
Noting that the date for the joint meeting with the Council has to be rescheduled, Vice Chair
Danaher said that he and Chair Cook would meet with the Mayor and Vice Mayor to discuss
topics for the meeting.
NEW BUSINESS
ITEM 1: ACTION: Recommendation that the Utilities Advisory Commission Recommend that
Council Adopt a Net Energy Metering (NEM) Transition Policy
Assistant Director Jane Ratchye noted that, in accordance with the UAC’s recommendation,
Council adopted the proposed Net Energy Metering (NEM) Successor Program on August 22,
2016, but requested that staff return to Council with options for the NEM Transition Policy. She
added that Council also directed staff to use an alternate method to calculate the NEM cap.
Ratchye indicated that the original staff proposal for the NEM Transition Policy was that
customers would remain in NEM for 20 years from the date of interconnection and that
customers may expand their systems by up to 10% and still remain in NEM. However, solar
Utilities Advisory Commission Minutes Approved on: November 2, 2016 Page 3 of 6
photovoltaic (PV) system expansions larger than 10% would result in the entire system being
under the NEM Successor Program. Ratchye indicated that a community group, Carbon Free
Palo Alto, developed an alternative for the system expansion aspect of the Transition Policy
such that systems could expand and remain under NEM, but that the transition period would
be proportionally reduced by the amount of the increase. Ratchye said that the proposal is now
staff’s new recommendation. She explained that staff’s original proposal accommodated
increased systems that would be prompted by the need to replace a failed panel or two in a
system. The revised expansion policy accommodates larger PV system expansions that could be
prompted by the desire to increase a system size since the price of PV panels has decreased or
because electric use has increased with the addition of an electric vehicle (EV), or after
electrification of an appliance.
Ratchye indicated that the revised methodology for calculating the NEM cap is 5% of the sum of
the customer class non-coincident peak loads, rather than 5% of the overall system load. The
revised calculation increases the NEM cap from 9.5 megawatts (MW) to 10.8 MW providing
more room under the cap for the
Vice Chair Danaher described the NEM program as one that pays the retail rate for all PV
generation and noted that the program will transition to the NEM Success
Commissioner Johnston clarified that the original proposal allowed an expansion of a system by
up to 10% without any change in the transition period, but the new proposal would shorten the
transition period even with a system expansion of up to 10%. Ratchye said that this statement
was correct.
ACTION:
Commissioner Forssell made a motion that the UAC recommend that Council adopt the
proposed Net Energy Metering Transition Policy. Commissioner Johnston seconded the motion.
The motion carried unanimously (4-0, with Vice Chair Danaher and Commissioners Forssell,
Johnston, and Trumbull voting yes and Chair Cook and Commissioners Ballantine and Schwartz
absent).
ITEM 2. ACTION: Staff Recommendation that the Utilities Advisory Commission Recommend
that the City Council Approve Design Guidelines for the 2017 Gas Cost of Service Analysis
Vice Chair Danaher asked staff to provide some background on why the City completes cost of
service analyses (COSAs) prior to developing its rate proposals. Acting Rates Manager Eric
Keniston explained that, for gas and electric rates, the City is subject to the requirements of
Proposition 26, which requires that all rates be based on the cost of service. A cost of service
analysis allocates expenses across ratepayer groups.
Vice Chair Danaher noted that the City’s electric supplies are carbon neutral and that the
Council will consider a proposal to convert the gas supplies to be carbon neutral. He said that
the Council encourages, and the UAC supports, moving towards electrification.
Commissioner Forssell asked if the 9% projected rate increase in July 2017 will change as a
result of the COSA. Keniston responded that the system wide rate increase will be determined
by the City, but that the COSA may reveal the need to make adjustments between costs
allocated to different customer groups.
Utilities Advisory Commission Minutes Approved on: November 2, 2016 Page 4 of 6
Commissioner Johnston asked if there would be different customer groups identified. Keniston
said that this would be looked at and is addressed by proposed Design Guideline 3 (The COSA
should involve a review of all existing rate schedules for applicability in the COSA).
Senior Deputy Assistant City Attorney Jessica Mullan said that the first guideline is the overall
guiding principle and that any policies that may be considered must be compliant with the
overarching cost of service guideline and must be in compliance with Proposition 26.
ACTION:
Commissioner Trumbull made a motion that the UAC recommend that Council approve the
proposed Design Guidelines for the 2017 Gas Cost of Service Analysis. Commissioner Forssell
seconded the motion. The motion carried unanimously (4-0, with Vice Chair Danaher and
Commissioners Forssell, Johnston, and Trumbull voting yes and Chair Cook and Commissioners
Ballantine and Schwartz absent).
ITEM 3. DISCUSSION: Discussion of Energy Storage and Microgrid Applications in Palo Alto
Senior Resource Planner Shiva Swaminathan presented the study results on the application of
microgrid and energy storage systems in Palo Alto. He outlined that the study did not find any
cost-effective application for such system at present, but anticipated the proliferation of energy
storage in the coming years as cost decline and value for such services increase. He also
outlined elements of a potential storage pilot project for 125kW/500 kWh at a cost of
$250,000.
Commissioner Trumbull noted the Commission’s recent discussion of potentially encouraging
customers to switch from natural gas to electricity, and asked about reliability if a customer
used only electricity. Swaminathan acknowledged that, having two fuel sources coming to your
home—electricity and natural gas—will have diversification value in the event of an emergency
like an earthquake. However, there may be other customers who want to eliminate the smoke
coming out of their smoke stacks at home by burning gas; for them, electrification may be the
solution. Swaminathan said that it is a trade-off each person has to make.
Vice Chair Danaher asked staff to explain the State’s establishment of storage mandates.
Swaminathan explained that the State is interested in storage to manage intermittent
renewables like solar and wind. Since storage is a fast-acting resource and can respond to the
vagaries of intermittent resources, storage is expected to take on a larger role in the coming
years.
Commissioner Forssell noted that backup power is one value stream shown in the analysis, but
there are other values too such as frequency regulation. Swaminathan concurred.
Commissioner Forssell asked which customers value backup generation. Swaminathan
indicated that many customers such as hospitals and location with computer servers need
higher reliability service. He said that if a customer is totally reliant on electricity and does not
use natural gas, they may wish to have energy storage systems to improve reliability.
Utilities Advisory Commission Minutes Approved on: November 2, 2016 Page 5 of 6
Vice Chair Danaher noted to the visiting students in the audience that the City has large utility-
scale solar resources and other renewable supplies, but that the City relies on others to manage
the transmission grid to deliver this power to Palo Alto.
Vice Chair Danaher mentioned that the energy price arbitrage is a low value. Swaminathan
concurred.
Commissioner Forssell asked whether the pilot project proposal was to partner with a customer
to install storage at their site and learn from the operations. Swaminathan agreed, but
mentioned that the objective is to have more than one customer participate in the pilot.
Commissioner Johnston asked if staff had identified any customers to participate in the pilot.
Swaminathan said no, but that there have been inquiries.
Vice Chair Danaher agreed with the analysis finding that there was low value proposition at this
time and asked for the rationale for spending $250,000 for a pilot project. Swaminathan said
the objective was to learn about the technology, the permitting rules, how to optimally operate
the system, and the impact on such systems on the retail rate-making process. Vice Chair
Danaher asked if there was a way to reduce the cost. Swaminathan said that the project could
be scaled down, but the minimum size to bid ancillary services into the CAISO is 100 kilowatts
(kW), the size of the proposed pilot. Vice Chair Danaher mentioned the value is to determine
how to bid these resources into the CAISO system.
Vice Chair Danaher asked if we have control of Calaveras hydro project operation.
Swaminathan replied in the affirmative.
Vice Chair Danaher asked about the objective of a pilot. Swaminathan responded that this
technology is coming and the idea is to learn about how we could have a win-win solution in
conjunction with our customers; the question of whether we can afford such a pilot is part of
this discussion. Swaminathan indicated that staff believes that spending $50k/per year for 5
years in R&D funds may be a good use of funds to better prepare for the future.
Vice Chair Danaher asked for an explanation of the value chart. Swaminathan outlined the
multiple value chains shown in the “spider-chart” in the report.
Commissioner Trumbull again asked what storage techniques could be used to protect
customers from electrical outages if the City adopted an electrification strategy. Assistant
Director Jane Ratchye mentioned that the current reliability level is very high. She also pointed
out that no decision has been made about electrification and we are not walking down the road
of wholesale electrification yet. Commissioner Forssell added that the purpose of this
discussion today is to meet a legislative requirement under AB 25142 and not the topic of
electrification at the Commission’s prior meeting.
Vice Chair Danaher asked how Demand Response (DR) differs from storage. Swaminathan
mentioned that DR resources tend to be less expensive, but storage is faster acting and more
reliable.
Utilities Advisory Commission Minutes Approved on: November 2, 2016 Page 6 of 6
Vice Chair Danaher asked if there are other DR programs that would be more productive than
storage, such as EV batteries. Swaminathan mentioned that staff is working on a program with
EVs and expect to come to the Commission in the spring along with the storage
recommendation.
Vice Chair Danaher asked if staff could describe the City’s new technology program.
Swaminathan explained the elements of the Program for Emerging Technology (PET), which is
designed to provide an opportunity to demonstrate new technologies on City facilities or using
willing Utilities customers, at no cost to the City. Technologies tested under PET include PV on
streetlights with a grid monitoring sensor and motion sensing LED lights installed in City Hall’s
parking garage.
Commissioner Forssell said she supported the R&D pilot like Commissioner Danaher and that
she was looking forward to seeing a fleshed out pilot project proposal from staff.
ITEM 4. ACTION: Selection of Potential Topic(s) for discussion at Future UAC Meeting
Commissioner Forssell asked that she would like a discussion on the next steps on the Fiber to the
Premises (FTTP) project and stated that it could be a discussion at the UAC/Council joint meeting.
General Manager Shikada said that this would be a good topic to revisit with the Council at the
joint meeting.
Vice Chair Danaher noted that the Utilities strategic planning is also a topic that will be coming
to the UAC and could be discussed at the joint meeting.
ACTION:
None.
Meeting adjourned at 8:18 p.m.
Respectfully submitted,
