HomeMy WebLinkAboutE-1.1. Approval of Bonanza Power Sales Agreement with SCPPASCHEDULED ITEM E-1
TO: HONORABLE CHAIRPERSON AND MEMBERS OF THE AZUSA UTILITY BOARD
FROM: TIKAN SINGH, GENERAL MANAGER
DATE: FEBRUARY 26, 2024
SUBJECT: APPROVAL OF A RENEWABLE POWER SALES AGREEMENT BETWEEN CITY
OF AZUSA AND SOUTHERN CALIFORNIA PUBLIC POWER AUTHORITY
SOURCED FROM A CO-LOCATED SOLAR AND BATTERY PROJECT
DEVELOPED BY BONANZA SOLAR, LLC
BACKGROUND:
To maintain clean air standards, reduce greenhouse gas emissions, and provide for a sustainable energy
future, California has established Renewable Portfolio Standards (RPS) that require all electric utilities to
serve a minimum percentage of retail sales of electricity from eligible renewable energy resources, such
as wind, solar, geothermal, and small hydro. Senate Bill 100 (2018) requires Azusa to serve at least 60%
of electricity sales from renewable energy resources by 2030. Senate Bill 1020 (2022) requires Azusa to
serve 90% of electricity from zero-carbon resources by 2035. Azusa Light and Water (ALW) began its
renewable resource portfolio in 2003. Since then, a few power purchase agreements have met their useful
life and expired. To ensure continued compliance with statutory RPS requirements, it is necessary to
further contract for renewable generation.
RECOMMENDATION:
Staff recommends the Utility Board take the following action:
1) Approve Power Sales Agreement between Southern California Public Power Authority and
City of Azusa for purchase of 20 Megawatts (MW) of solar energy and 10 MW of energy
storage for 20 years; and
2)Authorize the General Manager, or his designee, to enter into the long-term Renewable Power
Sales Agreement between the City of Azusa and Southern California Public Power Authority

Under California law, all load-serving entities are mandated to serve a specific fraction of their retail load
with renewable energy resources, which is called a Renewable Portfolio Standard (RPS). The initial RPS
was signed on April 12, 2011, under Senate Bill X1 2. Before that, ALW and other utilities established
their own renewable energy goals, which were around 20%. SB X1 2 mandated all electric utilities and
entities serving electric load in California produce and/or procure specific volumes of renewable energy
products, as measured by percentage of retail electricity sales. The law further stipulated that the
minimum volume of renewable energy had to be derived from resources interconnected within, or
first scheduled directly into California. These would be called Portfolio Content Category 1 (PCC1)
resources. Other amounts of procured energy could be satisfied by imported renewable energy (Portfolio
Content Category 2) and/or by “unbundled” renewable energy credits (Portfolio Content Category 3). In
2015, the state Legislature passed SB 350, “The Clean Energy and Pollution Reduction Act” which set a
50% clean energy standard to be achieved by 2030. That bill also set new requirements for doubling
energy efficiency and for wide-scale transportation electrification. In 2018 the state Legislature passed SB
100 which set a 100 percent carbon free target by 2045 and a 60% renewable energy requirement by 2030.
In 2022 SB 1020 sets a 90% zero-carbon target by 2035 and a 95% zero-carbon goal by 2040.
Azusa’s Current Renewable Energy Portfolio
Azusa’s commitment to clean energy began in 2003 by purchasing the wind output of the High Winds
Energy Center in Solano County, CA, for 20 years. ALW’s latest participation in a renewable project
transpired with the purchase of the wind output of the Mesa Wind Project located in Palm Springs, CA.
ALW’s current renewable energy portfolio consists of:
The modeled generation output from these variable resources place ALW initially in the mid 60% RPS
range and subsequently leveling down due to the 50% range due to expiring contracts and resource
degradation. By 2030, ALW is expected to be shy of a 60% renewable resource composition, unable to
meet the SB 100 target.

Planning post-2030, staff assessed a proposed resource via a Southern California Public Power Authority
(SCPPA) Request for Proposal. Out of that proposal, the Cities of Pasadena and Azusa pursued further
interest in the Bonanza Solar and Battery Energy Storage Project. ALW values three components from
renewable projects: 1) the reasonably-priced energy output and its proximity to the load zone, 2) the
Resource Adequacy value, if any, from a renewable project, and 3) the environmental attributes for ALW
to claim the resource as RPS-eligible. The commercial operation date of a project is also important so
that ALW can promptly meet the target RPS mandates. The Bonanza project, commencing operations in
2029, fulfills ALW’s need to boost its RPS portfolio further.
The Bonanza Solar Project includes both PV solar and a Battery Energy Storage System (BESS) with a
4-hour duration. The BESS output will be offered into the market and will offset project costs. The
proposed agreement also offers “Full Capacity Deliverability Status,” a critical attribute allowing a project
to claim Resource Adequacy (RA). This status ensures full output to the California grid. This RA
commodity has become critically scarce as the grid transitions from fossil-fueled resources. The project
will be capable of providing output from the battery during the critical evening hours. The Bonanza project
costs $47.76/MWh for delivered solar energy and $16.84/kW-Month for BESS.
Adding the Bonanza resource will raise ALW’s RPS portfolio to the mid-70 % range through 2035-2036.

After agreement review and negotiations, Pasadena, ALW, and SCPPA staff recommended the project to
the SCPPA board. As offtakers to the Bonanza project, Azusa and Pasadena recommended to SCPPA,
as facilitators under the Joint Powers Agreement, to have the SCPPA Board approve a power purchase
agreement with Bonanza. In January 2024, with the condition precedent based upon the approval of the
Power Sales Agreements from the Pasadena and ALW Boards, the SCPPA board approved a Power
Purchase Agreement with Bonanza. It is recommended that the Utility Board approve this agreement with
SCPPA.
FISCAL IMPACT:
The expected cost for delivered solar generation and BESS usage is approximately $4.4 million annually.
Sufficient funds will be budgeted from Capacity and Energy Fund 33-40-775-550-6590.
