Item 4.b.
CENTRAL SAN
April 20, 2020
TO: REAL ESTATE, ENVIRONMENTAL AND PLANNING COMMITTEE
FROM: MELODY LABELLA, RESOURCE RECOVERY PROGRAM MANAGER
REVIEWED BY: JEAN-MARC PETIT, DIRECTOR OF ENGINEERING AND TECHNICAL
SERVICES
ROGER S. BAILEY, GENERAL MANAGER
SUBJECT: RECEIVE UPDATE ON SENATE BILL (SB) 100 CALIFORNIA
RENEWABLES PORTFOLIO STANDARD PROGRAM
Staff is providing this memo in response to Real Estate, Environmental and Planning (REEP) Committee
Chair Pilecki's request for information on how SB 100 will overall affect Central San.
SB 100 Renewables Portfolio Standard (RPS) Program, signed into law by former Governor Jerry Brown
on September 10, 2018, established the 100 Percent Clean Energy Act of 2018, which increased the
RPS requirement in California from 50 percent by 2030 to 60 percent, and created the policy of planning
to meet all of the state's retail electricity supply with a mix of RPS-eligible and zero-carbon resources by
December 31, 2045, for a total of 100 percent clean energy.
As this law only applies to electricity retailers, the potential impact to Central San may be an increased cost
for electrical grid purchases in the future. However, it is important to note that PG&E is already well
underway to achieving these renewable energy milestones. For example, in 2018, PG&E's base power
mix included 39 percent renewable energy. See Attachment 1 for details on PG&E's 2018 Power Content
Label. Plus, if Central San moves forward with its own solar energy project on the Lagiss Property, the
vast majority of Central San's future power purchases would be locked in by a long-term (typically 25
years) power purchase agreement and not subject to PG&E's increases for the cost of power. This would
not be the case for power transmission costs, as Central San would still be subject to any future PG&E
cost increases due to investments in the power grid, such as any PG&E improvements to increase system
reliability and minimize power safety shutdowns due to fire risk.
Central San's solar energy consultant, Russell Driver of ARC Alternatives, will participate in the April 20,
2020 REEP Committee meeting and offer his expert opinion on how SB 100 may affect Central San in
the future.
