If you live in Contra Costa, Marin, Napa or Solano counties, you’ve likely seen both MCE 和 PG&E on your electricity bill. You might be wondering: What’s the difference between MCE and PG&E — and which one keeps my energy costs lower?
Let’s break it down so you can make the most affordable and sustainable choice for your home or business.
MCE and PG&E Work Together
First, it’s important to know that MCE is a Community Choice Aggregation (CCA) program. That means MCE buys the electricity you use while PG&E continues to handle billing and maintaining the power lines and wires that deliver electricity to you. You’ll still get one bill from PG&E, but it includes separate line items for MCE generation charges 和 PG&E delivery charges.
In short:
- MCE = Power supplier (the source of your electricity)
- PG&E = Utility delivery and transmission provider (the poles, wires, and customer service)
Your city or town council (or county board of supervisors, if you are in an unincorporated area) voted to join MCE, making MCE your default electricity generation provider by California state law.
If you open a new PG&E account in one of our 38 个成员社区, your electricity generation service will automatically come from MCE, unless you opt out. As an MCE customer, you will continue to get your gas service, electricity delivery, billing, and power line maintenance from PG&E.
Comparing Electricity Rates: MCE vs. PG&E
When it comes to cost, MCE’s generation rates are and have always been less expensive than PG&E’s. As of 2025, MCE’s Light Green plan (60% renewable) contains more renewable energy than PG&E’s standard generation plan (23% renewable). PG&E’s added fees make MCE’s total costs about $1.50 more per month for the average home, while providing more than twice as much renewable energy and access to programs to help lower your bills and increase your home comfort and safety.
Total bill costs depend on your usage pattern, seasonal rates和 additional PG&E delivery fees, which are the same no matter who supplies your electricity. That means MCE’s advantage comes from slightly lower generation costs 和 higher renewable content, not changes to transmission or service fees.
MCE has not had a general rate increase since January 1, 2023. PG&E has executed over 10 rate changes over the last 3 years and is proposing rate increases in 2027, 2028, 2029 and 2030.
