All Programs

Programs are the functions ColumbiaGrid carries out, and they are the building blocks for the organization's business plan.  Each program is defined in a separate Agreement, a legal contract among the signing parties.  Entities do not have to be members of ColumbiaGrid to sign on as a participant in any program, and they do not have to sign up for more than one program unless they choose to do so.  Funding for each program is kept and accounted for separately.

    Grid Reliability & Expansion Planning (Core Services Overview)

    Timeframe: April 2007 - Ongoing
    Status: Active

    ColumbiaGrid is one of the four U.S. regional transmission 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, Where, and When are the potential future reliability needs of the grid (i.e. independently assessing needs)?

  • What and Which cost-effective and efficient projects should be built to mitigate or solve the reliability needs (i.e. regional collaboration to develop solutions)?

  • Who should build, benefits from, and should pay for the projects (i.e. allocating costs)?




  • ColumbiaGrid's transmission 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, and go beyond, their respective FERC Order 890 or Order 1000 requirements.
