Level 1 for certified small systems, decision within 10 business days of a complete application, and PGE's own checklist recommends applying and waiting for approval before beginning any construction. documented
After install and local electrical inspection: send the signed agreement plus inspection proof, PGE site-inspects, swaps in a bidirectional meter, then issues permission to operate. documented
1:1 net metering up to 25 kW residential, monthly rollover, annual leftovers donated to low-income programs. PGE publishes a net metering capacity map, check your address before designing. documented
Battery quirk: non-export batteries need a signed letter stating the battery will not backfeed. documented
