HomeMy WebLinkAboutG-2.1. Semi-Annual Report on ALWs Energy Portfolio
INFORMATION ITEM G-2
TO: HONORABLE CHAIRPERSON AND MEMBERS OF THE AZUSA UTILITY BOARD
FROM: RICHARD TORRES, ASSISTANT GENERAL MANAGER – RESOURCE
MANAGEMENT
DATE: JUNE 24, 2024
SUBJECT: SEMI-ANNUAL REPORT ON AZUSA LIGHT AND WATER'S ENERGY
PORTFOLIO
BACKGROUND:
The recently adopted 2024 Energy Risk Management Policy sets refreshed guidelines and limits for
purchasing and selling energy-related products. Certain policy deliverables include establishing a risk
management committee and providing a semi-annual report to the utility board covering risk and hedging
topics and incorporating projected costs, market changes, and potential changes in projected costs.
RECOMMENDATION:
Staff recommends the Utility Board take the following action:
1) Receive and file the Semi-Annual Report on Azusa Light and Water’s Energy Portfolio
ANALYSIS:
A key component of the Energy Risk Management Policy is providing a semi-annual report to the Utility
Board. This semi-annual report includes issues related to hedging, projected costs, changes and
probability in projections, market changes and opportunities, and potential stress events.
-Current Azusa Light & Water (ALW) Portfolio
The ALW portfolio currently consists of participation in two wind projects, one small hydro project, five
solar projects, one natural gas plant, one large hydroelectric project, and one nuclear project. ALW staff
schedules six of these resources.

-Projected Costs
The ALW power resource portfolio has changed due to two power purchase agreement terminations and
a new resource addition. As of the beginning of 2024, ALW no longer receives small hydro generation
from its Metropolitan Water District purchase agreement or wind output from its High Winds agreement.
However, the addition of the Mesa Wind facility not only replaces but adds to ALW’s renewable profile.
Recognizing that the actual metered output of Mesa Wind needs to be recorded and assessed, staff has
conservatively projected its output. Based on initial projections, staff feels comfortable that the ALW
portfolio is roughly 60% to 100% hedged, mainly depending on the seasonal nature of its renewable
energy output. From its projections, staff sees most remaining energy needs affecting the period of July
through December. The lowest wind patterns are seen in the fall and winter, thus creating energy gaps in
the ALW portfolio. According to the Energy Risk Hedging Policy, staff will hedge these remaining energy
needs from its initial projections. Finally, as Mesa metered generation data is gathered, staff will continue
tuning its hedging needs.
-Energy Markets
Forward energy market pricing have somewhat eased compared to previous years. This is mainly due to
milder weather, healthier hydrological conditions, and new online resources. The charts below provide a
view of the market showing signs of a healthier energy supply.

-Market Changes
In contrast to the relatively stable energy markets, the forward capacity market costs have increased
significantly. Resource Adequacy capacity, also known as the amount of megawatts required to be
ready for dispatch to maintain stable grid operation, has become an issue for many utilities that do not
own dispatchable generation. The capacity market is scarce due to low northwest rainfall (less hydro to
share), more variability in renewable energy, hot southwest power demands, and less gas-based
dispatchable generation. The dispatchable energy storage buildout pace is insufficient to compensate for
the scarcity. The California Independent System Operator (CAISO) and the Energy Commission are
aware of this market change. Assembly bill (AB1373) proposes the State (via the Electricity Supply
Strategic Reliability Reserve Program) to serve as a central procurement entity for capacity and
allocating costs to utilities that did not fully meet their capacity needs.

-Changes in Projections
The Mesa Wind project “capacity value” will lessen some of the procurement burden to ALW. The
final value from Mesa Wind is yet to be formally set by the CAISO causing some changes in the
projected remaining needs for ALW capacity.
The above is a snapshot of what brokerage firms see in the capacity market. These prices are
exponentially higher than 5-10 years ago. Staff, however, sees these “quotes” move quickly, and at
times, the cost to procure is lower as the trading month is near.
In February of this year, staff recommended, and the UB approved the Bonanza Power Agreement,
which includes ALW’s interest in 10 MW of battery storage capacity. The expected date for the
solar/battery facility's operation is the fall of 2027. This investment will help provide cost stability to
ALW’s capacity needs. In the meantime, staff will continue procuring capacity from their counterparties
at the best reasonable cost.
-Potential Stress Events
Some stress events that impact ALW are project construction delays, severe weather conditions,
including cold fronts and wildfires, and gas fuel scarcity. Mesa Wind construction delays stressed
ALW’s ability to generate corresponding renewable energy primarily in 2023. This stress event has
impacted the annual renewable composition for 2023, showing that 28.7% of ALW’s retail sales were
derived from renewable energy resources. It is key to state that despite the lower percentage from 2023,
ALW has procured sufficient Renewable Energy Credits to supplement any gaps to meet its obligations
for the entire mandated Renewable Portfolio Standard (RPS) compliance period of 2021-2024.
Unfortunately, public state reports such as Power Source Disclosures and Power Content Labels are not
congruent with RPS filings. In summary, ALW will fully comply with meeting its renewable targets per
the RPS regulations.

-Summary
From an energy supply perspective, the ALW portfolio is well hedged and compliant with the Risk
Management policies. Supplemental energy purchases will continue to fill the periods of lower
renewable output. Staff will procure short-term capacity and soon recommend an additional battery
storage proposal to the Board. Regarding its renewable progress, the staff sees little to no risk in
achieving current and future RPS targets. In the next semi-annual report, staff will report any changes in
projections that differ from this report.
