Highlights

  • The Federal Energy Regulatory Commission (FERC) has accepted Southwest Power Pool's (SPP) Consolidated Planning Process (CPP) as just and reasonable, endorsing a unified approach that integrates long-term transmission planning and generator interconnection in a single framework. FERC approved SPP's use of standardized, upfront GRID-C charges for interconnection customers, paired with continued Highway/Byway cost allocation to load, as consistent with cost causation principles.
  • The CPP's 20-year and 10-year planning assessments are designed to identify and build multi-value transmission projects in advance of need, rather than reacting to individual interconnection requests.
