OK HB2747

Amends electric utility regulations to require Corporation Commission orders within 180 days for natural-gas-fired generation facility applications (compared to 240 days for other fuel types), and mandates utilities secure firm natural gas transportation contracts through competitive bidding for new gas plants

Establishes a regulatory asset deferral mechanism starting July 1, 2025, allowing public utilities to defer 90% of depreciation expense and return on qualifying electric plant investments, with deferred amounts included in rate base and recovered through 20-year amortization

Grants Corporation Commission authority over new high-voltage transmission lines (300 kilovolts or greater) approved in Southwest Power Pool plans, requiring retail electric suppliers and rural cooperatives to solicit competitive bids overseen by an independent evaluator for transmission facility extensions

Prohibits Commission-regulated retail electric suppliers from offering ratepayer-funded incentives, rebates, or inducements to promote customer switching from natural gas to electricity

Requires automatic customer refunds within 90 days, plus interest at the one-year U.S. Treasury Bill rate, if a utility terminates a natural gas generating facility project after implementing a rate adjustment mechanism to recover construction costs
