This bill establishes new regulations for the Corporation Commission regarding the management and approval of electric grid resources in Oklahoma. It defines key terms such as "firming power," "guaranteed power capacity," and "intermittent generation," and mandates the Commission to create rules ensuring that electric grids are both affordable and reliable. The bill stipulates that new power generation resources must be selected based on the lowest total monetary cost, and existing resources cannot be retired prematurely unless it results in lower costs. Additionally, the grid must maintain a guaranteed power capacity of at least 115% of peak net load and meet specific operational requirements during extreme weather events.

Furthermore, the bill prohibits the Commission from approving new intermittent generation sources unless they are supported by firming power for a minimum of 48 hours during peak load periods. It emphasizes that guaranteed power capacity must be a primary consideration in decisions regarding the retirement or addition of electric generation sources. The Commission is also directed to coordinate with regional transmission organizations to ensure cost-effective and reliable power supply. The act is set to take effect on November 1, 2025.
