Washington, D.C. — Transmission planning in the western U.S. involves several regional entities:

  • The California Independent System Operator (CAISO);
  • NorthernGrid, which covers the Pacific Northwest and Intermountain West; and
  • WestConnect, which serves the Southwest.

In May 2024, the Federal Energy Regulatory Commission (FERC) finalized its long-term regional transmission planning and cost allocation rule to strengthen the grid to meet future demand. How will the West be impacted by the new rule?
