Community Choice Energy

Walnut Creek Joins Clean Energy Program MCE

To address climate change and implement its Climate Action Plan, the City of Walnut Creek has joined MCE to offer residents and businesses additional electric energy choices.

MCE is a public, not-for-profit electricity provider offering a Community Choice Energy program that enables the City to partner with other local governments to purchase cleaner electricity for Walnut Creek residents and businesses. MCE gives consumers more options for their electricity provider, competitive rates, and cleaner energy.

Community Choice Energy is a hybrid approach between private investor-owned utilities and public municipal utilities that was approved by the California legislature through AB 117 in 2002. Since September 2016, MCE has become the default electricity provider. PG&E continues to be responsible for transmitting and distributing electricity through the grid, maintaining infrastructure, billing customers, and providing customer services. Learn more about MCE by visiting MCE's website or calling 1 (888) 632-3674.



 MCE_how it works



MCE's goal is to have rates that are competitive with PG&E. Rates are approved by MCE's Board of Directors, made up of an elected official from each participating City and County. Check MCE's and PG&E's websites for the most up-to-date rates. MCE's website has a residential and commercial sample cost comparison.

Discount Customers

CARE, FERA, and Medical Baseline customers are unaffected by enrollment; these customers automatically receive the same discount with MCE as they would with PG&E.  Contact PG&E and MCE for more information about how overall rates compare.


Customers with rooftop solar, or who are interested in going solar, can learn more about MCE's solar Net Energy Metering policy, rates, and incentives here. For detailed questions about solar rates or Time of Use rates, please call MCE's call center at 1 (888) 632-3674.


PG&E will still send your monthly bill, but instead of one fee that combines both your electric delivery fees and electric generation fees, your bill will show separate charges – one for PG&E electric delivery and one for MCE electric generation. MCE’s generation rates will simply replace PG&E’s generation rates; they are not an added fee.

 Unincorporated Walnut Creek

Contra Costa's Board of Supervisors voted on March 15, 2016, in favor of moving ahead with studying the potential for a local Contra Costa County Community Choice Energy program. In Spring 2017, the County's Board of Supervisors voted to join MCE. Several other Contra Costa County cities have also recently voted in 2017 to join MCE. Residents and businesses in unincorporated areas switched to MCE's service in Spring 2018, with an opportunity to opt-out and remain with PG&E.
