How the PG&E process runs

  1. Customer signs A&A (Form 79-1151A) in YourProjects portal
  2. Contractor completes Standard NEM/NBT application (79-1151B) and uploads consumer protection docs and supplements
  3. Automated network capacity check; engineering review if needed
  4. Install and pass local building inspection; upload final permit/inspection
  5. Customer signs Interconnection Agreement
  6. PG&E issues Permission to Operate letter - never energize before PTO

Net metering cap1000 kW

Systems must be sized to load; no incentive for oversizing. Certain SF/Oakland secondary network ZIPs need Rule21Gen review.

Storage, EV and stamps

Battery storage

Storage ≤10 kW can use the Standard (simplified) application with PV ≤30 kW; storage >10 kW routes to Complex NEM/Rule 21 review.

EV chargers

Checklist asks for number of EVs charging on site and anticipated future annual usage increase.

Common issues the utility lists

  • A&A not signed before Step 2
  • Missing contractor/customer email addresses
  • Equipment not on CEC list without spec sheet/UL1741 documentation
  • Portal SLD not matching actual system without custom SLD
  • Service address on bill not matching final building permit
  • Variance needed but not requested

Gridpol’s pre-submission check covers these before we file.
