City of Richmond Snapshot
• 82.1% enrolled in MCE service, 2.5% enrolled in MCE’s Deep Green 100% renewable service option and 7.6% have solar on their home or business. • 31% enrolled in California Alternate Rates for Energy (CARE), which provides up to 35% monthly discount on electricity for qualified households.
Community Sponsorships and Collaborations
• Sponsored City of Richmond’s Juneteenth event, Drive Clean Bay Area events, and programs with Rich City Rides, Urban Tilth, Groundwork Richmond and Collaborising for California Clean Air Coalition’s Clean Air Day. • Hosted multifamily workshop with APEN and SOMAH for HOAs, affordable housing developers and CBOs throughout Contra Costa County.
• Virtual Power Plant (VPP) Program launched: an opportunity for 42 small businesses, 4 large industrial customers,10 zero net carbon homes, and 90 residential homes to participate and receive new equipment and technology. • Working with city staff to advance Contra Costa Transportation Authority (CCTA) grant to advance EV charging opportunities is select zip codes. 4 Key Drivers of Power Supply Statistics
• MCE’s Integrated Resource Plan
• Actual vs. forecasted retail sales
• Actual vs. forecasted renewable energy production
• Variable hydrologic conditions
• Product availability: RPS & GHG-Free
• AB 1110 emission accounting methodology
5 MCE Planning & Procurement Process
• MCE’s resource planning process utilizes a two-phased approach with attention given to:
• Clean-energy commitments: resource commitments and open positions are evaluated in consideration of current IRP targets.
• Price risk mitigation/budgetary certainty: resource commitments are evaluated in consideration of potential market price exposure and budgetary/rate impacts. • Clean-energy purchases/sales are pursued to align resource commitments with IRP targets on a projected basis.
• Additional clean-energy purchases or sales may be executed throughout the year to balance commitments relative to needs.
• Certain contractual commitments are specifically executed to minimize MCE’s exposure to market price volatility but may not impact power supply stats. 6 MCE Historical Retail Sales Growth

Percentage of Retail Sales Covered by Retired Unbundled RECs3: 0% 0% 0% 0% 1The eligible renewable percentage above does not reflect RPS compliance, which is determined using a different methodology. 2Unspecified power is electricity that has been purchased through open market transactions and is not traceable to a specific generation source. 3Renewable energy credits (RECs) are tracking instruments issued for renewable generation. Unbundled renewable energy credits (RECs) represent renewable generation that was not delivered to serve retail sales. Unbundled RECs are not reflected in the power mix or GHG emissions intensities above.

Clean E nergy Comparison: MCE vs. PG&E
MCE Light Green: Renewables PG&E Base Plan: Renewa bles MCE Light Green: Clea n Energy* PG&E Base Plan: Clean Energy* Other Considerations
• Renewable and Carbon-free energy supply
• PG&E Hydro Allocations
• Ongoing drought conditions have created supply constraints and uncertainty regarding future resource availability • CPUC Procurement mandates
• Increased competition amongst CCA buyers
• Supply constraints have resulted in sustained price increases • Evolving resource mix/requirements
• Hourly portfolio balancing
• Promoting reliability within a substantially carbon-free supply portfolio 15 Thank You
