CITY COUNCIL STAFF REPORT
Meeting: November 16, 2010
Subject
Report on the status of the Solar Power Purchase Agreement (SPPA) project.
Recommended Action
Receive report and provide direction to staff.
Description
The SPPA will allow the city to purchase renewable energy generated among carport
photovoltaic arraysat City Hall, Corporation Yard, and the Quinlan Community Center, which
will beconstructed and maintained by two unique vendors.
A Solar Power Purchase Agreement (SPPA) is a financial arrangement in which a third-party
developer owns, operates, and maintains the photovoltaic (PV) system and a host customer
agrees to site the system on its roof or elsewhere on its property (i.e. carport structure) and
purchase the system’s electric output for a predetermined price and period. Power purchase
agreements address many of the traditional barriers to adoption for organizations looking to
install solar systems including high up-front capital costs, system performance risk and complex
design and permitting processes.
Challenges of Siting Renewables
One of the major barriers for local governments topurchaserenewable energy systems is the
high upfront costs involved. Although purchasing a renewable energy system outright is
generally considered to be the most cost effective strategy in the long-term, the high up front
capital costs are often prohibitive. An alternative method of financing was pursuedin order to
utilize renewable energy and thereby decrease energy costs. In the past five years, the financial
sector and renewable energy providers have partnered to develop innovative third party
ownership financing structures, such as Power Purchase Agreements, to take advantage of the
tax incentives available to the private sector. However, historically these financing structures
require significant legal, procurement, property management, and engineering expertise to
execute leading tohigh transaction costs that have presented a barrier to local governments.
The Opportunity of Regional Aggregation
In order to reduce the transaction costs associated with Power Purchase Agreements and to
support the regional expansion of renewable energy generation, the members of the Joint
VentureSilicon Valley-convenedClimate Protection Task Force created a collaborative
procurementprocess, lead by Santa Clara County. By leveraging the contractual resource
investment of the lead agency and creating a procurement pool, this approachenabled an
affordable group purchase of renewable energy for all participating agencies.The Association of
Bay Area Governments (ABAG) and the Department of Energy (DOE) later joinedthis effort,
offering programmatic support and applying unique areas of subject matter expertise.
ThisRegional Power Purchase Agreement (RPPA)is one model which provides an opportunity
to reduceboth the upfront capital barriers to direct ownership and the transaction costs associated
with third party financing:to moveour community and organization closer to siting solar and
setting a leadership example throughout the Bay Area. Additionally, by creating a regional PPA
rather than individual PPAs for each city, the costs of developing the agreement are reduced
significantly for all parties involved. This method not only conserves funds, but also accelerates
the financing process and deployment of renewable energy technologies, promotes energy and
tax-dollar savings, and supports local economic development.
Since the summer of 2008, the collaborative has researched solar power purchase agreement
issuances, and developed RFQ and RFP documents. The overall objective of this effort has been
multifaceted; to reduce transaction costs associated with development and negotiation of RPPA
contracts, to obtain favorable pricing and terms through a large scale regional aggregate
purchase, to rapidly deploysolar and other renewable technologies, and to enable participation in
RPPA contracts for small governmental entities that would otherwise be unable to participate in
RPPA financing structures due to the size of project sites.
Over 22 jurisdictions in Santa Clara and San Mateo County expressed an interest in
“piggybacking” on the RPPA effort. On February 2, 2010 Cupertino’s Council authorized a
Memorandum of Understanding for Cooperative Purchasing of Power with the County of Santa
Clara, allowing Cupertino’s participation in a County solicitation, a Request for Proposals for a
th
Regional Renewable Power Purchase Agreement (RFP# RRPPA-001-310) issued March 29,
2010. The first Request for Proposals (RFP) issuance included nine participating public
agencies, including the cities of Cupertino, Los Gatos, Milpitas, Morgan Hill, Mountain View,
and Pacifica, along with the County of Santa Clara, the Valley Transit Authority, and the South
Bayside Waste Management Authority.
The initial RFP was to procure 14MW of renewable power through power purchase agreements.
The Department of Energy, Optony (an independent solar consulting firm) and Joint Venture
Silicon Valley assisted the County of Santa Clara in assembling an evaluation panel consisting of
members of the collaborative. The panel reviewed bid proposals from nine vendors,several of
which submitted proposals for more than one bid bundle (grouping of sites for procurement
purposes). This process officially closed on September 8, with the selection of qualified firms
for five bundled project types: large (>650kW/site), medium (160kW –650kW/site), small
(<160kW/site), small rooftop installations (<220kW/site), and other systems (solar thermal PV,
fuel cell, micro-wind turbine).
Cupertino sites included in this RFP were all for solar canopy/carport parking installations at
City Hall, Quinlan Community Center and the Corporation Yard. Prior to participating in the
RFP, Cupertino worked with City staff, Siemens(through the previous Detailed Energy Audit),
and Critigen to evaluate the solar potential of these sites. A summary of findings are as follows:
FacilityAnnual kWh Generated Average Annual kWh % Met by
by PV SystemUsed at SiteSystem
City Hall475,005524,65091%
Quinlan Community Center140,564495,59528%
Corporation Yard450,503143,595314%
Renewable Energy Financing Options
This pilot project considered several available financing structures to installrenewable energy
systemsamong participating Bay Area agencies including: owned, leased or Power Purchase
Agreement. Each financing structure has advantages and disadvantages:
1.City-Owned-The City would own the solar power generation system. Advantages include
eligibility for incentive funds and ownership of tradable emission credits. Disadvantages
include significant up-front capital costs, annual maintenance expenses for approximately 20
years, and the replacement of inverters between years 10 and 13. Owned systems are
generally considered appropriate for sites where security and access are restricted.
2.Lease-to-buy-Advantages include no up-front capital expenses, and long-term leases that
allow amortization of costs with the potential for ownership. There is a growing market of
lenders and brokers interested in leasing solar installations.
3.Solar Power Purchase Agreements(SPPA) -This option creates a long term agreement for
the purchase of power generated from the solar installation. Typically SPPA's have 20 year
terms with prices determined through negotiations. In the past several years, local
governments throughout California have funded renewableenergy projects through lease to
purchase, and Solar Power Purchase Agreements (SPPA). These types of financing structures
provide the opportunity to obtain solar power without the up-front capital investment as the
power generation system is designed andinstalled by a third party provider and financed
through a third party financier. The governmental entity benefits from capped or slowed
growth in electricity rates, as the normal utility bill is paid to the financier through terms
established in the SPPA. In California, at least ten jurisdictions have issued SPPA’s in the
past two years. These issuances include the California Department of General Services, City
of Fresno, San Francisco Public Utilities Commission, County of Solana, County of San
Diego, and County of Ventura, among others. Project staff reviewed all ten SPPA issuances
to compare terms and conditions.
The proposalcurrently being negotiated is working towards the creation of a SPPA.
Project Steps and Status
1.Issue Request for Information-COMPLETE
The purpose of the RFI was to test the assumptions and information gathered to date on different
financing mechanisms and procurement approaches. The RFI required vendors toshow their
experience with financing mechanisms, the extent of that experience, possible terms that the
County could expect, how the market would respond to bundled projects, whether additional
sites should be considered and whether collaborative procurement at scale would deliver
significantly reduced power purchase prices.
Nineteen vendors responded to the RFI. Most firms have experience with a variety of financing
methods. Installed price per kwH power varies as a reflection of the cost of capital, theFederal
tax incentive for private sector investment and state solar incentives, and economies of scale in
supply and financing. The attached RFI Summary Graphs provide general information from the
responses to the RFI. Preliminary observations provided bythe County include:
Most respondents indicated that their firm had been in business between 2 and 5 years -The
significance of this finding is that traditional municipal government procurement criteria
require extensive years of experience. Doing so in the renewable energy market would
preclude most firms from competition.
Most respondents are specialized in either solar ground-mount or rooftop systems. A few
firms offer expertise in two or more technology areas, but they tended to be large vendors.
The majority of respondents indicated that the installed cost of power for systems in
general was below $0.19 per kwH. Many firms in lower cost ranges were newer market
entrants.
Most respondents indicated that economies of scale exist in collaborative procurement, and
that these are quantifiable around 5% for bundled project packages of 10 MW, 15 % for
packages of 20 MW, and 20% for packages of 50 MW. These discounts are incorporated to
be compared to the cost per kwH of PG&E rates over the 20 year term of powerpurchase
agreements.
2.City Signs Memorandum of Understanding – COMPLETE
In order to obtain commitments, County staff requested a Memorandum of Understanding
(MOU) from all jurisdictions. The MOUs were due tothe County on February 5, 2010. Staff
th
held a mandatory meeting with City attorneys and staff on December 4, 2009 to review PPA
document terms, the RFP process and other issues. At this meeting 12 jurisdictions indicated that
they wanted to participate in the first RFP issuance. These include; VTA, Morgan Hill, Mountain
View, Cupertino, Sunnyvale, Los Gatos, Milpitas, County of San Mateo, Pacifica, Burlingame,
Foster City and the Silicon Valley Waste Management Authority.. The MOU was finalized
th
through the review of the Board of Supervisors on February 9.
3.Conduct Detailed Solar Site Survey - COMPLETE
Per Section 2.C. of the aforementioned Memorandum of Understanding, to participate in the bundled
PPA project, cities were required to submit proposed real property sites that may accommodate
renewable energy installations (individually, a “Site Survey”, and collectively the “Site
Surveys”) prepared by a licensed engineer in a uniform, industrystandard format. To achieve
this requirement, the city joined neighboring jurisdictions to work with CH2M Hill (now Critigen,
LLC) to conduct solar site surveys by piggyback upon the competitively bid contract won by the
company to analyze Santa Clara County-owned assets.
The survey was solar site analysis and electrical and structural analysis. The city completed this
process with three sites and abutting parking lots, Community Hall, Quinlan Community Center and
the Corporation Yard. Work concluded in February and the results of the study are included in
Attachment C.
4.Issue Request for Proposal (RFP) for Power Purchase Agreements COMPLETE
The Request for Proposals to procure an initial 4MW of renewable power for county sites
th
through power purchase agreements was issued on March 29through BidSync. This
th
Solicitation was managed in two steps: Step 1 –Pre-Qualification due by 3PM on May 7, 2010
and Step 2 –Final Selection for Renewable Power Generating (RPG) Systems Bundles due by
3PMon June 29, 2010.
5.Evaluate Vendor Proposals COMPLETE
The proposals for seven qualified firms were reviewed between the RFP deadline by the
project’s leadership team which included the following members:
Siva Darbhamulla, Chief of Design Services, County of Santa Clara
Ben Foster, Vice President, Optony
Caroline Judy, Assistant Director, Government Support Services, County of Alameda
Jerry Lahr, Power Program Manager, Association of Bay Area Governments
Kara Gross, Vice President, Joint Venture: Silicon Valley Network
Rachel Massaro, Associate Director of Climate Initiatives, Joint Venture: Silicon Valley
Network
Steve Mitra, County Counsel, County of Santa Clara
Lin Ortega, Utilities Engineer/Program Manager, County of Santa Clara
Chris Schroeder, Purchasing Agent, City of Milpitas
Mary Tucker, Energy Program Manager, City of San Jose
A detailed summary of the RFP evaluation criteria is provided on pages 27 –29 in the RFP
document, but focus primarily within four categories: firm and team qualifications, relevant
project experience, technical expertise and proposed system cost. Using these factors, the
Evaluation Committee determined the responsiveness and best value quality of the proposal.
Using this criteria the following firms were selected for the following bundles:
Large –>650kW/site
Medium –160kW –650kW/site
Small –<160kW/site
Small Rooftop –<220kW/site
Other -solar thermal PV, fuel cell, micro-wind turbine
Relevant to Cupertino, the evaluation team selected Borrego Solar Systems, Inc.
(www.borregosolar.com) to contract with cities to site medium sized bundles and Ecoplexus
(www.ecoplexus.com) todevelop the City’s small sites.
6.Negotiate Final Contract Initiated: October2010, Anticipated: November 2010
Over the course of the month of October, legal and environmental representatives from each
participating agency have participated in a series of joint contract negotiations with SPPA
vendors. The coordinating committee convened this process to save both staff time and leverage
the collective bargaining power of representative public agencies. Staff met in advance of
initiating the vendor negotiation to discuss each agency’s key contracting requirements and
establish a strategy to ensure all parties achieved mutually beneficial joint outcomes from the
process. Vendor negotiations are scheduled to continue through November 10.
7.Project Commissioning andConstruction,Anticipated: December 2010 –December 2011
Staff propose the consulting firm, Optony, which has been assisting the County and partner
agencies in the solar renewable energy procurement project to date, be retained throughout the
design, engineering and construction phases of the project. In this role, Optony will ensure that
the renewable energy system is (1) optimized through the review of system drawings and plans,
is (2) constructed using the same components required through the contract, (3) meets industry
standards for installation and production, and is (4) properly maintained to achieve all applicable
warrantees. In partnership with staff, Optony will also work with Pacific Gas and Electric to
develop an interconnection plan and verify that all California Solar Initiative (CSI) milestones
are being met with rebates and deposits transferred back to the City. Furthermore, supporting
staff will work with the vendor to ensure that parking lot closures are minimized during the
construction phase and that vendor strictly adheres to the arborist’s tree mitigation plan and
procedures.
8.Monitor and report on system production ONGOING
The RFP clearly states that the firm must also provide for real-time monitoring and verification
of power generated at each site listed during commercial operation. To achieve this requirement,
the SPPA builds in a series of activities including the installation and maintenance of a meter at
the delivery point and a monitoring system for each generating facility. Meters and all metering
activities are to be provided, installed, owned and maintained, programmed and operated at the
vendor’s expense and in compliance with of all applicable Transmission Provider Tariffs and the
Buyer-PG&E Interconnection Agreement. The aforementioned monitoring system may be
provided as a web-based tool or interface to view, collect and store data, in real time, including
the energy delivered, greenhouse gas emissions reduced, AC efficiency, peak DC efficiency and
total percent of energy used from the system.

Sustainability Impact
Installing solar will eliminate fossil fuel demands at the Civic Center, Corporation Yard and
Quinlan Community Center to help the City to achieve environmental objectives, including the
Solar Action Area Goals established in the Bay Area Climate Compact to increase by 30% the
use of renewable sources for electrical energy by the end of 2013, from a 2008 baseline. This
project will reduce the city’s largest source of operational greenhouse gas emissions and air
pollutants (facilities), providing the City a head start to implementing actions that mitigate the
impactsof climate change in advance of the creation of its Climate Action Plan.Specific
considerations pertaining to the environmental attributes of the system include the following:
1.CEQA
Staff engaged two independent consultants to assess the project proposal under CEQA. In both
cases, the consultants confirmed that the solar carport system would be categorically exempt
under section 15303. Section 15303(e) consists of construction and location of limited numbers
of small new equipment or structures and specifically identifies carports within its provisions.
This is consistent with the findings of the California Energy Commission report titled
“Distributed Generation: CEQA Review and Permit Streamlining,” which notes that under 15303
“certain types of DG may qualify if they have small footprints and the site’s zoning allows power
generation to occur there.”
2.Urban Heat Island Effect
Anurban heat island(UHI) is ametropolitan areawhich is significantly warmer than its
surroundingrural areas.Sources indicate that the main cause of the urban heat island is
modification of the land surface byurban developmentwhich uses materials which effectively
retain heat. To address this concern for the solar carport project, it should first be noted that
there are twoforms of solar energy. The first is solar thermal conversion, which uses sunlight to
create heat and then electrical power (typical for solar hot water projects). The second is
photovoltaic conversion, which uses sheets of special materials to create electricity from the sun.
"Photo-" means "light," and "voltaic" means "producing electricity." Proposed for installation at
the City of Cupertino are the second form of solar technology, solar photovoltaics, not solar
thermal, which can often be associated with “waste heat” resulting from the solar thermal
conversion.
Industry best practices document solar modules collecting solar radiation and being cooled by
ambient air movement withequivalent or better than heat collection on concrete/asphalt.
Moreover, existing underlying pavement and parked cars are similar in albedo (i.e. reflectivity)
to a solar systemand support structures that are light in color, further reducing concerns that
urban heat island could result from this project.Upon furtherresearch,staff foundagencieswith
UHI subject matter expertise(i.e. EPA, Lawrence Berkeley National Laboratory) presentsolar
carport/parking structures as an urban heat island mitigation measures, in that this infrastructure
provides anideal means to provide cover thereby reducing heat transfer between pavement and
its surroundings.
3.Proposed Tree Mitigation and Replacement Plan
To ensure photovoltaic modulesmay gain access to maximum sunlight exposure, the vendor
proposed the City replace approximately 55 trees with 58 trees in an alternative location. Also
proposed for the site is the addition of shade and drought tolerant vegetative groundcover to
mitigate aesthetic changes. In an arborist report commissioned by the City, 18 trees proposed for
removal were deemed “low suitability”, 30 were deemed “moderate suitability” and 12 were
deemed “high suitability” for preservation. None of the trees are considered “protected trees’
pursuant to Section 14.18.035 of the City Code. 39 trees would require increased pruning to
ensure they do not grow above their current height. Lastly, in addition to the city’s own actions,
the vendor offers a tree replacement program as part of its service, thereby doubling those trees
proposed for replacement among the city’s sites.
Fiscal Impact
The price proposals for Renewable Power Generation System bundles are presented at a fixed
price rate (cents per kWh) with an annual escalator (in percent/year) for each kWh delivered to
and metered at the electrical interconnection point, both with and without environmental
attributes (RECs). In pricing, firms were made aware that the agencies (i.e. Cupertino) own the
environmental attributes(RECs)of the system installed, not the firm. As such, these bundles
seek to deliver the best value with rates demonstrably lower than forecasted PG&E pricing over
the 20-year lifecycle of the installed renewable power generation system.
Renewable energy power generation presents two distinct fiscal benefits for Cupertino: potential
revenue generation from the sale of generated power and expenditure savings resulting from the
use of renewable energy sources. Estimated savings from the proposed installation of carports at
the Civic Center and Corporation Yard are estimated to be $625,000 over the 20 year term.
Pricing estimates have not yet been provided for Quinlan Community Center. Furthermore, the
value of the infrastructure investment on behalf of the vendor is estimated between $1.5M and
$2M.
To achieve these savings, vendors propose the transition to a Time-of-Userate (depicted below)
to more closely follow the production of solar systems, as these schedules peak in the daytime
and summer. These (A6) rates enable over-production during peak times and allow for the
purchase of power during off-peak times at much lower rates. Through this structure, utility
customers can get to a nearly $0 electricity bill with approximately a 70% energy offset.
Savings represented above are reflective of a pricing model built upon certain assumptions that
may be subject to change based on Council and staff project-based priorities or requests.
Consideration of the following variables is underway, and will be fully accounted for in the
subsequent staff report:
1.Aesthetic Features or Additional Design Attributes Cost: TBD
Though more detailed financial information will be provided in the next staff report for
Council’s review, savingspresented
in this report were establishedby the
vendor as a base system price. More
specifically, equipment and
installation materials evaluated by
the vendor in its financial analysis
are similar in nature to the image
provided below and include, but are
not limited to the following features
open framing with module racking,
inverters, rain gutters, and
undercanopy lighting. It should be
noted that changes to this equipment
to accommodate design features or
aesthetic attributes will change the
vendor pricing, and ultimately the projected utility savings for the City. Staff are working to
evaluate suite enhanced features available for the project, and the costs attributed to these
features,to present to Council for itsconsideration.
2.Project Commissioning Consultant: Maximum Cost: $18,000
To date, the public agencies involved in this collaborative solar procurement efforthave been
heavily supported by independent solar consultant, Optony, as these agencies are both new to the
technology and financing mechanism.To advance the project through the commissioning phase,
participating agencies were provided a proposalfor Optony to provide the following hands-on
services: project inspection, project coordination, technology and installation inspections,
specification compliance, and final project certification.These services will be offered at the
discounted rate of $6,000 per site (vs. $11,000), due to the size of the project and number of
participants.
3.Ongoing Pruning Cost: TBD
Staff are currently evaluating whether or not additional staff time will be required to achieve the
pruning goals of the PPA vendor. Proposed currently for the Civic Center is to maintain, at
current height, the blackwood acacias on the eastern edge of the parking lot and the flowering
pear on the western edge/sidewalk adjacent to the parking lot. This additional pruning cost is not
part of the Power Purchase Agreement, and would, thereby, be the responsibility of the City.
4.Replanting Cost: TBD
In addition to ongoing pruning costs, staff and potential vendors are working to evaluate the cost
for replanting native and shade tolerant trees and ground cover where current trees are proposed
for replacement. Note that replacement is only suggested for foliage that will shade the proposed
solar photovoltaics (see Attachment D: Arborist Report and Tree Restoration Plan). As a means
to reduce this cost, staff are also evaluating opportunities to apply rebates available from the
Santa Clara Valley Water District for replacement of non-native water intensive plants. These
costs could be included in the Power Purchase Agreement, which would increase the vendor rate
and reduce cost savings for the City, or the City could independently finance the work.
Power Purchase Agreement Contract Terms
The approach pursued to negotiate the Solar Power Purchase Agreement is “master agreement”,
shared jointly among all participating parties within the County,with addenda for each site
including a site license (possibly separate clone agreements for each site). This approach
supportsagencies to not only achieve economies of scale among typically high legal and
contracting costs, which could ultimately drive up the PPA pricing, but also gain access to more
favorable terms and conditions not commonly offered by vendors for sites of this size and scale
(i.e. system performance cap, as described in further detail below). The following section
outlines the major terms of the proposed Solar Power Purchase Agreement.
1.Term and Buyout
20 year contract from “Commercial Operations Date”
Buyout available starting at year 6, and every year thereafter
Buyout is “Fair Market Value” based on independent appraisal
End-of-term extension for 5 year periods, if agreed
If terminated, all equipment will be removed and site restored to original condition
2.Billing & Payments
Monthly billing based on calculation of electricity generated times fixed rate (based on final
contract)
Annual escalation of fixed rate by 3-4% (based on final contract)
Payments due monthly via electronic funds transfer
3.Renewable Energy Credits
City will select to own the RECs or not at the inception of the PPA
Owning the RECs will cost an additional $0.01 to $0.02/kWh
4.Early Termination
Available from year 1
Payment schedule included with prohibitive costs through year 6
After year 6, based on FMV plus removal costs
PPA provider must remove all equipment and restore facility to original condition
5.Performance
System will perform on an annual basis to the forecasted kWh output, adjusted for weather
and Force Majeure
If the system under performs below 85%, PPA provider will reimburse City for lost savings
If the system over performs above 110%, City not required to purchase, but may if beneficial
Under-performance below 50% over full year is a default
6.System Design & Construction
System designs reviewed by Optony for best practices and appropriate size
All equipment must meet or exceed RFP specifications

City must indemnify PPA provider if City’s employees or facilities cause damage
9.Force Majeure
Weather, earthquakes, flood, accidents and other typical events included
Utility interruption or curtailment included
Equipment failure or system underperformance not included
Additional Considerations and Concerns
1.Parking Lot Closure
The installation of carport structures and required electrical wiring and conduiting will require
portions of the parking lot to close during construction, so as to maintain a safe and efficient
worksite. To minimize disruptions for civic center visitors during construction, the vendor has
proposed a phased approach to target installations for unique sections of the parking lot. The
construction initiation date is to be negotiated by the city and the vendor, and will strategically
target the time at which the civic center parking lot usage is lowest, likely in the early summer
when school is not in session. Furthermore, during this time, staff will work to evaluate and
designate alternative parking locations for library patrons.
2.Parking Space Loss
The proposed designs will not eliminate any currently available parking spaces, as this has, and
will continue to be, a staff priority.
Value Proposition
All parties involved in the Solar Power Purchase Agreement seek to, and will most likely, gain
unique benefits through this collaboration. Furthermore, community membersand employees,
not currently involved in this service offering may also derivevalue, if the partner agencies elect
to expand the opportunity beyond public facilities and parking lots. Outlined below are the
potential gains for these stakeholder groups.
1.All Santa Clara County Solar Power Purchase Agreement Project Participants
This Regional Power Purchase Agreement (RPPA) is one model which provides an opportunity
for all participating agencies to reduce both the upfront capital barriers to direct ownership and
the transaction costs associated with third party financing.Additionally, by creating a regional
PPA rather than individual PPAs for each city, the costs of developing the agreement are reduced
significantly for all parties involved. In fact, pricing proposed through this collaboration are
estimated at 10-14% lower due to a group purchase. This method not only conserves funds, but
also accelerates the financing process and deployment of renewable energy technologies,
promotes energy and tax-dollar savings, and supports local economic development.
2.City of Cupertino
Beyond the benefits of a collaborative approach, this proposal to install carport structures will
offer two new opportunities for the City: (1) utility price stabilityand (2) electric power
reliability during times when backup power is needed. Moreover, the conservative estimated
savings from this generation sourceare $625,000. Approximately $30,000 of these savings could
be prioritized for reinvestment in public works-led energy efficiency, water conservation or
alternative transportation projects that further reduce the greenhouse gas emissions associated
with city operations. This cost-saving renewable energy generating system is estimated to be
approximately $2M for direct purchase, not including annual O&Mcosts
3.Cupertino Community Members –Residents & Businesses
The City is just beginning to explore the myriad of opportunities to leverage and expand this
project to residential and commercial enterprises across our community. Potential programs that
have been demonstrated around the country include: “Friends and Family” program from the
vendors, bulk negotiation on behalf of consumer groups (i.e. employees, nonprofits, schools,
neighborhoods), collaboration with local bank/credit union to finance solar projects, education
and outreach on City solar initiatives, City-funded rebates to encourage deployment, City-
subsidized feasibilities studies for businesses, and others. Proposals to advance this work are
forthcoming.
Recommended Action

If Council should direct staff to proceed, staff will take the final enabling actions to advance the
project scope:

Staff engaged two independent consultants to assess the project proposal under CEQA. In
both cases, the consultants confirmed that the solar carport system would be categorically
exempt under section 15303. Section 15303(e) consists of construction and location of
limited numbers of small new equipment or structures and specifically identifies carports
within its provisions. This is consistent with the findings of the California Energy
Commission report titled “Distributed Generation: CEQA Review and Permit
Streamlining,” which notes that under 15303 “certain types of DG may qualify if they
have small footprints and the site’s zoning allows power generation to occur there.”
