Unlike CCAs that offer one-time rebates, MCE provides ongoing monthly credits. This model provides steady value over time and doesn't depend on limited funding cycles.
MCE Battery Demand Response
OPENProgram requires allowing MCE to occasionally dispatch your battery during peak demand. Backup power capability is preserved.

Not all cities participate. Check your PG&E bill or mceCleanEnergy.org to verify your enrollment.
Example Cost & Value Breakdown (2026)
MCE's program provides ongoing value rather than upfront cost reduction.
At $640/year average, effective payback on a $13,500 battery is ~21 years. Add outage protection value and payback improves.
TOU Savings in MCE Territory
MCE customers pay PG&E's delivery rates. Time-of-use pricing means a battery can save money by storing cheap off-peak energy and using it during expensive peak hours.
TOU savings are typically $300–$500/year for a single Powerwall-sized battery. Combined with MCE's $240/year credit, total annual value reaches $540–$740.

What is MCE?
MCE (formerly Marin Clean Energy) is the Community Choice Aggregator serving Marin County, Napa County, most of Contra Costa County, and parts of Solano County. MCE sources your electricity while PG&E handles delivery and billing. MCE has one of the most established battery incentive programs among California CCAs.
What's MCE's battery incentive?
MCE offers a $20/month bill credit for customers who enroll their battery in their demand response program. Unlike upfront rebates, this is an ongoing payment — $240/year for as long as you participate. Over a 10-year battery lifespan, that's $2,400 in credits. The program requires allowing MCE to occasionally dispatch your battery during grid stress events.
How does MCE's battery program work?
When you enroll, MCE can signal your battery to discharge during peak demand periods (typically hot summer evenings). Your battery helps reduce grid strain instead of the utility firing up expensive peaker plants. In exchange, you receive a monthly bill credit. You retain backup power capability — your home is still protected during outages.
Is MCE's battery program currently open?
Yes, MCE's battery program is generally open to new enrollments. However, capacity limits may apply. Visit mceCleanEnergy.org or contact MCE directly to confirm current availability and enrollment requirements for your area.
What counties does MCE serve?
MCE serves Marin County (all cities), Napa County (all cities), most of Contra Costa County (Richmond, San Pablo, El Cerrito, Concord, Martinez, Walnut Creek, Pleasant Hill, Lafayette, Moraga, Danville, San Ramon, and unincorporated areas), and parts of Solano County (Benicia, Fairfield). Check your PG&E bill to confirm MCE is your generation provider.
How much is the bill credit worth over time?
MCE's $20/month credit adds up: $240/year, $2,400 over 10 years. While smaller than upfront rebates offered by some CCAs, it's ongoing and doesn't depend on limited funding cycles. Combined with TOU savings of $300–$500/year, total annual battery value in MCE territory is $540–$740.
What are the TOU savings in MCE territory?
MCE customers pay PG&E's delivery rates, which include time-of-use pricing. Peak hours are 4–9pm daily, with rates approximately $0.50–$0.60/kWh vs. off-peak at $0.35–$0.45/kWh. A battery can save $300–$500/year by shifting usage away from peak hours. Combined with MCE's $240/year credit, total annual value is $540–$740.
Is the federal tax credit still available?
The 30% Residential Clean Energy Credit for homeowner-purchased battery systems expired December 31, 2025. It is not available for systems you buy outright in 2026. If you lease a battery or use a PPA (Power Purchase Agreement), the installer may still receive the credit and pass savings to you. Ask installers about lease/PPA options.
Which batteries qualify for MCE's program?
MCE accepts major battery brands including Tesla, Enphase, Franklin, SolarEdge, and Sonnen. The battery must be permanently installed, connected to your home's electrical system, and capable of receiving dispatch signals. Check MCE's website for their current approved equipment list and technical requirements.
Can I still use my battery during outages if I'm enrolled?
Yes. MCE's program doesn't affect your backup power capability. During grid outages, your battery powers your home as designed. MCE only dispatches your battery during peak demand periods when the grid is operational. Your battery's backup reserve is protected.
What's the difference between MCE and PG&E?
MCE is your electricity generation provider — they source the power. PG&E handles delivery, billing, and grid infrastructure in MCE territory. Your bill comes from PG&E but shows charges from both entities. For battery incentives, MCE runs their own program; PG&E has no direct battery rebate for residential customers.
Does battery storage make financial sense in MCE territory?
MCE territory is one of the better markets for batteries in California. Between MCE's $240/year credit and TOU savings of $300–$500/year, annual value is $540–$740. For a $12,000–$15,000 battery, payback is 16–28 years without other incentives. Add backup power value during outages and the economics improve further.
How do I enroll in MCE's program?
Visit mceCleanEnergy.org and look for their battery storage or demand response program. You'll typically need to provide proof of battery installation and enroll through their portal. Some installers can assist with enrollment. Once approved, credits begin appearing on your PG&E bill.
Where can I verify this information?
For MCE program details, visit mceCleanEnergy.org directly. For PG&E delivery rates (which apply in MCE territory), visit pge.com/tariffs. For SGIP status, visit selfgenca.com. Program terms change — always verify directly before making purchase decisions.
