Corporation Commission; directing Commission to promulgate certain rules relating to affordable and reliable electricity; providing for coordination with certain utilities and organizations. Effective date.

SB 1003 requires Oklahoma's Corporation Commission to create rules ensuring electricity grid affordability and reliability. It mandates that the grid maintain 115% guaranteed power capacity (sufficient backup power) to prevent outages, requires new wind/solar projects to include backup power costs in their total expense calculations, and directs the Commission to select new power sources based on the lowest total cost to ratepayers. These rules directly affect electric utilities and the Corporation Commission, with specific requirements including preventing premature retirement of existing power plants unless cost-effective and ensuring power sources meet continuous operating needs during extreme weather. The bill aims to prevent power shortages through measurable reliability standards, effective November 1, 2025.
