Understanding the Two-Bill Structure
In San Jose and across Silicon Valley, commercial electricity bills have two distinct components:
- PG&E delivery charges (~⅔ of total bill): These cover transmission, distribution, wildfire mitigation, and state-mandated program costs. All customers in PG&E territory pay these regardless of who generates their electricity. These charges rose approximately 4% in delivery plus an additional 19% in non-bypassable surcharges for CCA customers.
- Generation charges (~⅓ of total bill): For San José Clean Energy (SJCE) and SVCE customers, this is where the 40% rate cut appears. Both CCAs aggressively reduced generation rates for 2026, offsetting PG&E’s delivery increases.
Why PG&E Non-Bypassable Charges Are Rising
The 19% increase in non-bypassable charges reflects several cost layers that CCA customers cannot avoid:
- Wildfire recovery bonds: PG&E’s $13.5 billion 2017–2018 wildfire liability, securitized into ratepayer-backed bonds, continues to flow through as a fixed charge.
- Power Charge Indifference Adjustment (PCIA): This “exit fee” ensures CCA customers pay their share of legacy PG&E generation contracts, even though they no longer buy power from PG&E.
- Grid modernization: PG&E is investing heavily in undergrounding power lines, advanced metering, and substation upgrades across the Bay Area.
The March 2026 Base Services Charge
Starting March 2026, PG&E restructured commercial billing with a new Base Services Charge — a fixed monthly fee that separates some service costs from per-kWh usage pricing. This has important implications for commercial solar customers:
- High self-generation reduces your per-kWh bill but does not reduce the Base Services Charge.
- Businesses with large solar arrays may see diminished savings as a larger share of their bill becomes fixed.
- Energy storage paired with solar remains economically viable, especially for CAISO’s growing battery storage market.
CAISO Market Dynamics Driving Silicon Valley Costs
The CAISO wholesale market is experiencing persistent negative pricing during midday solar peaks and increased curtailment — the market has more energy capacity than structural demand growth can absorb. For commercial buyers, this means:
- Time-of-use rate structures increasingly penalize evening peak consumption (4–9 PM).
- Commercial solar without storage captures less value as midday energy is worth less.
- CAISO’s EDAM launch in May 2026 may help equalize prices across the Western US, potentially reducing California’s extreme duck curve dynamics.
What San Jose Commercial Buyers Should Do
- Verify your CCA: Determine whether you’re served by SJCE or SVCE — their generation rate structures differ. Both offer competitive commercial tariffs.
- Audit non-bypassable charges: Request an itemized bill breakdown from PG&E to understand exactly how much of your bill is delivery vs. generation vs. surcharges.
- Evaluate the Base Services Charge impact: If you have on-site solar, model how the new fixed charge structure affects your savings profile.
- Consider battery storage: With negative midday pricing and expensive evening peaks, batteries that shift solar generation to peak hours improve ROI significantly.
