Oregon’s commission rule (OAR 860-039 (Net Metering Rules, incl. net metering interconnection review); OAR 860-082 (Small Generator Interconnection, <=10 MW, non-net-metered)) does not bind public power districts; Northern Wasco County PUD sets its own interconnection policy. We confirm its form on the first project. ORS 757.300 also applies to PUDs, municipal utilities and electric cooperatives: net metering required for systems <=25 kW; governing body sets terms (annual excess credit use, additional safety/testing requirements) after public notice; may not require extra liability insurance or tests for code-compliant systems; may not cap below 0.5% of historic single-hour peak.
