Planning and Expansion Overview

ColumbiaGrid is one of the four U.S. regional planning entities in the Western Interconnection. The mission of ColumbiaGrid’s grid expansion planning is to identify potential needs and to determine reasonable solutions, or mitigations, pertaining to the reliable long-term planning and use of the Members’ and Qualified Non-Member Parties interconnected transmission systems. In short, ColumbiaGrid’s core grid expansion planning process seeks to answer these fundamental questions:

  • What are the potential future reliability needs of the grid (i.e. assessing needs)?
  • What projects should be built to mitigate or solve the needs (i.e. planning solutions)?
  • When and where are the projects needed (i.e. enabling regional cooperation)?
  • Who should build, benefits from, and should pay for the projects (i.e. allocating costs)?

  • ColumbiaGrid’s singular planning mission and process is defined and enabled by the Planning and Expansion Functional Agreement (“PEFA”) and works in conjunction with the regulatory overlay of the Order 1000 Functional Agreement to enable ColumbiaGrid’s Planning Parties to meet their respective FERC Order 890 or Order 1000 requirements.
