The Commission issued a final rule reforming both the pro forma Open Access Transmission Tariff and the pro forma Large Generator Interconnection Agreement to remedy deficiencies in the Commission’s existing regional transmission planning and cost allocation requirements pursuant to section 206 of the Federal Power Act. The final rule, as amended, requires transmission providers in each transmission planning region to participate in a regional transmission planning process that is sufficiently long-term, forward-looking, and comprehensive to ensure the identification, evaluation, and selection of more efficient or cost-effective regional transmission facilities to address long-term transmission needs, and to establish methodologies to allocate the costs of facilities selected in those planning processes in a manner that is just and reasonable, as required by the Federal Power Act.  The final rule, as amended, also directed other reforms to improve coordination of regional transmission planning and generator interconnection processes, require consideration of certain alternative transmission technologies in regional transmission planning processes, and improve transparency of local transmission planning processes and coordination between regional and local transmission planning processes (Docket No. RM21-17-000). This rule was previously reported as 1902-AF87.
