What this means for you

✓ What you can do

  • Apply for interconnection like any small generator (Residential <=300 kW / 25,000 kWh-yr), typical fee $125.
  • Use portable panels with a power station, never connected to house wiring, with no permission at all.
  • Install conventional rooftop or ground-mount solar through the standard interconnection process.

✕ Not yet / not allowed

  • Plug a grid-tied kit into an outlet without an interconnection agreement; it can breach your service terms.
  • Expect a permit or wiring exemption; none exists without a law.
  • Count on HB 4060 this year: Passed House 88-4 (3/24/2026); Senate Energy, no action; died at sine die; deferred to 2027.

What the rules say

Oklahoma's HB 4060 cleared a House committee but died in the Senate; OG&E/PSO interconnection rules apply.

What happened in 2026. HB 4060: Passed House 88-4 (3/24/2026); Senate Energy, no action; died at sine die; deferred to 2027.

Before you plug in: Oklahoma checklist

  1. The rule that applies is Oklahoma Corporation Commission's interconnection process: OAC 165:40 Subchapter 9 net metering.
  2. A plug-in kit falls in the smallest tier (Residential <=300 kW / 25,000 kWh-yr). Not published (OG&E); Stillwater muni $125.
  3. Permits: 2023 NEC; CIB licensing; homeowner exemption.
  4. Only consider kits with a UL 1741-listed inverter (UL 3700 preferred); a non-listed inverter will not be approved anywhere.
  5. What exports are worth: Monthly netting, excess at avoided cost.
  6. If approval is slow or costly, a portable panel and power station (never connected to house wiring) needs no permission.
  7. Watch HB 4060: Passed House 88-4 (3/24/2026); Senate Energy, no action; died at sine die; deferred to 2027.

Your utility's rules in Oklahoma

No utility in Oklahoma publishes a rule that specifically allows or bans outlet-connected generation, so the general interconnection agreement is what applies. Here is what the largest residential utilities say and require.
