Southwestern Power Administration April 2023 – Federal Register Recent Federal Regulation Documents

The Administrator, Southwestern Power Administration (Southwestern), is proposing to update the Peaking Energy Schedule Submission Time in Southwestern's existing Integrated System Wholesale Rates for Hydro Peaking Power (P-13A) Rate Schedule. Southwestern has determined that the shift in Peaking Energy Schedule Submission Time from the current 2:30 p.m. CPT to the proposed 8:30 a.m. CPT provides Southwestern with more flexibility and greater certainty when making replacement power purchases, and better aligns with regional energy market considerations.
