On September 4, 2025, the Board of Directors of Southwest Power Pool (SPP), the regional transmission organization (RTO) responsible for much of the central United States, passed Revision Request 696 (RR 696), paving the way for SPP to propose that the Federal Energy Regulatory Commission (FERC) modify SPP’s Open Access Transmission Tariff (Tariff) to create a 90-day path to interconnection for large loads and supporting generation. SPP is expected to file this Tariff change proposal with FERC in the coming weeks. Pending FERC’s decision, SPP aims to administer one of the fastest interconnection study processes in the nation and allow expedited processing of new large loads on the SPP transmission system.
