CleanPowerSF
2022 Integrated Resource Plan Progress
September 13, 2022
1 2
WHAT IS AN INTEGRATED
RESOURCE PLAN (IRP)?
An IRP is an energy planning tool to support
achieving policy goals and meeting regulatory
requirements.
State law requires retail sellers of electricity to
develop an IRP that evaluates electricity supply
and demand and identifies energy resource options
that can deliver reliable and cost-effective energy to
customers.
CCA IRPs are reviewed and certified by the
California Public Utilities Commission (CPUC),
every two years.
CleanPowerSF’s next IRP is due November 1,
2022
KEY TERMS
3 • Portfolio: collection of generation
resources used to serve electricity
demand.
• Conforming Portfolio: the specific mix
of electric generation resources that
meet CPUC requirements.
• Scenario: variations on a future state
or objective that may influence the
resources included in a portfolio.
INTEGRATED RESOURCE PLAN
PORTFOLIOS
4 Conforming
Portfolio
Uses inputs and assumptions
provided by the CPUC
Accounts for statewide goals
and targets
Minimal flexibility to incorporate
local electrification goals and
targets
Alternative
Portfolio
Uses inputs and assumptions
determined by CleanPowerSF
Accounts for local goals and
targets:
Transportation electrification
Building decarbonization
Provides flexibility to
incorporate community
preferences
COMMUNITY ENGAGEMENT:
PHASE 1 RECAP
5 What we
heard as
priorities
Reliability of sources, especially
resiliency in natural disasters
and extreme weather
More local renewable sources
Affordability of rates; ensure cost
does not become a barrier for
clean energy access
Emissions
reduction/environmental
sustainability of sources
Electrification and
decarbonization to meet climate
goals
Battery storage technology
Phase 1 Outreach
June-July
Digital Survey
• Launched June 5th; closed July 6th
• 68 responses received;
• 92.1% identified as a CleanPowerSF customer
Virtual Community Workshops
• Two workshops hosted (6/21, 6/23)
• Participation from 15 different organizations
including: 350 San Francisco, Climate Emergency
Coalition, Local Agency Formation Commission
(LAFCo), the Greenlining Institute, Sierra Club,
and Haight Ashbury Neighborhood Council.
COMMUNITY ENGAGEMENT:
WHAT’S NEXT?
Phase 2 Outreach
September-October
Goal: Solicit community feedback on the Integrated
Resource Plan modeling results to inform a Staff
recommended preferred portfolio.
Notice will be provided to 600+ community organizations in addition to Phase 1 survey respondents and
workshop attendees.

Upcoming engagement opportunities:
6 Written Public Comment Period
Modeling results will be made available for the
public to review. Written comments will be
collected via an online form.
Virtual Listening Sessions
CleanPowerSF staff will hold two virtual
listening sessions to hear from community
members and to directly answer questions.
