Peninsula Clean Energy Rate Selection Guide
Peninsula Clean Energy (PCE) is a not-for-profit Community Choice Aggregator that supplies clean electricity to San Mateo County and Los Banos. Customers are auto-enrolled in PCE generation while PG&E continues to deliver power and issue bills. Energy usage, billing, and 15-minute interval data are available through PCE's UtilityAPI-powered Data Connect platform and PG&E's Share My Data / Green Button programs.

Rate Recommendations by Use Case
Large commercial/industrial facility
Large C&I accounts get the strongest absolute savings from PCE's lower generation rate, since generation is a large share of a high-volume bill.
On B-19SV, PCE ECOplus generation ($0.06208/kWh) is roughly half PG&E's ($0.11754/kWh); delivery is identical either way. The TOU delivery structure rewards load-shifting away from peak.
- Stay on ECOplus unless 100% renewable is a procurement requirement
- Use Data Connect 15-minute data to shift load off PG&E delivery peaks
- Model the PCIA when comparing PCE vs PG&E bundled
Small/medium business
Small and medium commercial sites benefit from PCE generation savings with no action required beyond default enrollment.
PCE ECOplus generation on B-10S ($0.06952/kWh) is about 46% below PG&E's ($0.12971/kWh), lowering the all-in rate from ~$0.336 to ~$0.324/kWh.
- Pull billing history via Data Connect to confirm rate class
- Authorize an energy consultant through UtilityAPI for benchmarking
- Consider ECO100 if sustainability reporting needs 100% renewable
Sustainability / ESG-driven organization
Organizations with renewable-energy or carbon goals can upgrade to ECO100 for verified 100% renewable supply.
ECO100 adds only ~$0.01/kWh over ECOplus while delivering 100% renewable generation, useful for Scope 2 reporting.
- Quantify the ECO100 premium against your kWh before upgrading
- Document the renewable claim for GHG inventories
- Pair with on-site solar interconnected through PG&E
Historical Rate Trends
PCE adjusts its generation rates roughly annually and has historically priced generation below PG&E to deliver member savings while expanding renewable content. PG&E delivery rates, which PCE does not control, have risen steadily and are the main driver of total-bill increases on the Peninsula.
January 1, 2025
PCE set ECO100 at roughly 1.5 cents/kWh above ECOplus and maintained generation rates below PG&E.
n/aOverall trend: PCE generation has stayed consistently below PG&E generation; total bills are pushed up mainly by rising PG&E delivery and PCIA, not by PCE generation.
Next expected change: PCE typically reviews generation rates annually; PG&E delivery and PCIA update on PG&E/CPUC cycles.
Cost Optimization Strategies
Because PCE controls only generation, the biggest commercial savings levers are choosing the right PCE product, managing PG&E delivery demand charges, and shifting load using interval data.
Stay on ECOplus unless 100% renewable is required
For: All C&I accounts
ECOplus is already 100% carbon-free and prices below PG&E generation; only upgrade to ECO100 when a renewable claim is needed.
Manage PG&E delivery demand charges
For: Demand-metered B-10S/B-19 accounts
Delivery and demand charges are set by PG&E and often exceed generation cost; reducing peak kW lowers the largest part of the bill.
Use Data Connect interval data to shift load
For: TOU-billed accounts (B-19)
Export 15-minute data and move flexible loads off TOU delivery peaks.
To implement these strategies, you need your 15-minute interval data. Learn how to download Peninsula Clean Energy interval data →
Deregulated Market Shopping
This is not full retail choice. The only supplier decision is between PCE (default CCA generation) and PG&E bundled generation; PG&E always provides delivery and billing. Customers are auto-enrolled in PCE and may opt out to PG&E at any time.
How to Compare Peninsula Clean Energy Suppliers
- 01Compare PCE ECOplus/ECO100 generation rates against PG&E generation using the Joint Rate Comparison
- 02Confirm your PG&E rate class (B-1, B-6, B-10S, B-19) on your statement
- 03Decide between ECOplus (default) and ECO100
- 04Opt out to PG&E generation only if you have a specific reason
Contract Terms for Peninsula Clean Energy Supply Agreements
- No fixed-term contract; CCA enrollment is month-to-month
- Opt-out available at any time
- ECO100 upgrade can be elected or dropped
Common Pitfalls When Shopping Peninsula Clean Energy Rates
- The PCIA / Franchise Fee surcharge applies to CCA customers and narrows nominal savings
- PG&E delivery and demand charges are unaffected by the PCE choice
- Opting out to PG&E forgoes PCE's lower generation rate
Frequently Asked Questions
Does Peninsula Clean Energy set my whole electric rate?▾
No. PCE sets only the generation portion of your bill. PG&E sets delivery, demand charges, the PCIA/Franchise Fee, and taxes, and PG&E issues the single combined bill. For B-10S small/medium business, PCE ECOplus generation is $0.06952/kWh versus PG&E generation of $0.12971/kWh (Feb/Mar 2026), while the PG&E delivery rate of $0.21582/kWh is identical either way.
How does a business get its usage and billing data from PCE?▾
Through the Data Connect platform (powered by UtilityAPI) at data.peninsulacleanenergy.com. Businesses can view and export 4+ years of billing and 15-minute interval data in CSV, JSON, or Green Button XML, and can authorize consultants through UtilityAPI. PG&E delivery-side records are also available via PG&E Share My Data / Green Button.
What is the difference between ECOplus and ECO100 for commercial accounts?▾
ECOplus is the default product (about 50% renewable and 100% carbon-free). ECO100 upgrades to 100% renewable energy for roughly one cent more per kWh (e.g., B-10S generation $0.07952/kWh vs $0.06952/kWh). Delivery and other charges are unchanged.
Can third parties access PCE data through an API?▾
Yes. PCE supports Green Button Connect My Data through UtilityAPI. Vendors register at utilityapi.com/register/pce, pass PCE review, and pull billing and interval data via a JSON REST API or Green Button XML once a customer grants OAuth consent. There is no public EDI program; Green Button XML is the standards-based alternative.
Is there full retail electricity competition in PCE's territory?▾
No. PCE territory uses California's CCA model, which is partial choice: businesses choose PCE generation (the default, with opt-out to PG&E) but cannot select an unrelated competitive retail supplier. PG&E always provides delivery and billing under CPUC regulation.
