Community Choice Aggregation (CCA) Options
San Francisco's CCA. Green service (default) provides 100% renewable and/or GHG-free power at competitive rates; SuperGreen provides 100% California-certified renewable (Green-e certified) for roughly $7 more per month for a typical small business.
Current Rate Schedules
CleanPowerSF charges only for electric generation; PG&E charges separately for delivery. Effective March 1, 2026, SFPUC approved a 20-25% reduction in CleanPowerSF generation rates (25% for residential and large commercial E-19/B-19 classes, 20% for all others). For a typical small-business B-1 account using ~1,225 kWh/month, CleanPowerSF Green generation averaged $132.29/month versus PG&E default generation of $150.29/month and CleanPowerSF SuperGreen of $138.42/month (PG&E delivery of ~$360.57 is the same regardless of generation provider). Commercial generation rates are published by rate class and mirror the PG&E schedule (B-1, B-6, B-10, B-19, B-20) the account takes for delivery.

Rate Recommendations by Use Case
Small business / small commercial (B-1)
Most San Francisco small businesses are auto-enrolled in CleanPowerSF Green, which the published B-1 comparison shows is cheaper on generation than PG&E.
Verified data: ~$132.29/mo CleanPowerSF Green vs ~$150.29/mo PG&E generation at 1,225 kWh.
- Confirm you have not been opted out to PG&E generation
- Pull interval data via PG&E Green Button to validate usage
- Consider SuperGreen (~+$7/mo) for green-building credits
Medium commercial on time-of-use (B-6/B-10)
Medium accounts pay TOU generation on top of PG&E TOU delivery; load shifting compounds savings across both.
Both generation and delivery are time-differentiated, so off-peak shifting reduces total cost twice.
- Map 15-minute interval data to TOU windows
- Target HVAC and process loads for off-peak operation
- Re-check rate class against PG&E delivery schedule
Large commercial / industrial (B-19/B-20)
Large accounts received the deepest (25%) generation reduction in March 2026 and should re-baseline procurement assumptions.
The 25% B-19 generation cut materially changes CCA vs PG&E and vs DA economics.
- Re-run generation cost comparisons after the March 2026 cut
- Quantify PCIA exposure in any opt-out analysis
- Automate interval data via PG&E Share My Data for M&V

Cost Optimization Strategies
For CleanPowerSF C&I accounts the principal levers are generation provider election, load shifting against PG&E TOU delivery periods, and verifying PCIA exposure.
Stay on CleanPowerSF Green vs opting out
For: All commercial classes
Verified B-1 comparison shows CleanPowerSF Green generation below PG&E generation for the same usage; confirm before opting out.
Shift load off PG&E peak periods
For: TOU commercial / industrial accounts
Generation and delivery both carry TOU pricing on B-6/B-10/B-19/B-20; shifting load to off-peak reduces both components.
Evaluate SuperGreen for green-building value
For: Sustainability-driven accounts
SuperGreen adds a modest premium but qualifies for LEED and SF/CA Green Business points.

Deregulated Market Shopping
Within San Francisco, electric generation choice is structured through Community Choice Aggregation rather than open retail competition. Eligible accounts default to CleanPowerSF Green, can upgrade to SuperGreen, or can opt out to PG&E bundled generation. There is no independent retail electric supplier market for these accounts as there would be in a fully deregulated state.

Frequently Asked Questions
How do I pull interval data for a CleanPowerSF commercial account?▾
Because PG&E owns the meters, use PG&E Green Button Download My Data (for one-time CSV/ESPI XML export) or PG&E Share My Data (for automated API delivery). SFPUC's My Account - Power portal also shows hourly/daily usage graphically and SFPUC operates its own Green Button Connect program for registered vendors.
Does CleanPowerSF bill us directly?▾
No. CleanPowerSF generation charges appear as a line item on your consolidated PG&E bill; PG&E handles delivery, metering, and billing. CleanPowerSF is not an extra charge.
Is CleanPowerSF generation cheaper than PG&E for businesses?▾
For the published B-1 small-business benchmark (1,225 kWh/mo), CleanPowerSF Green generation averaged $132.29/mo versus PG&E's $150.29/mo. A 20-25% generation rate reduction took effect March 1, 2026, increasing the gap. Always compare against your own usage and rate class.
Can a third party (consultant/ESCO) access our data?▾
Yes, with your authorization. Register them as an SFPUC Authorized Representative for billing PDFs, or have them onboard via SFPUC Green Button Connect (SFTP) or PG&E Share My Data (OAuth API) for automated interval and billing data.
What does it cost to leave CleanPowerSF?▾
Opting out to PG&E generation may trigger a CleanPowerSF termination fee, and the PCIA and Franchise Fee Surcharge affect total-cost comparisons. Review both before switching.
