    Grid Reliability & Expansion Planning (Core Services Overview)

    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 insurance (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.

    Planning-Related Services (Non-core Services)
    ColumbiaGrid is committed to assisting its Members in all areas related to grid reliability and continually seeks new opportunities to provide additional value to the Members beyond the scope of ColumbiaGrid's core grid planning services. These 'non-core' services leverage ColumbiaGrid's core expertise and tools via separate agreements. Past examples include:
  • Independent Panel Review of Bonneville's Proposed South of Allston Project
  • Independent Technical Review of Physical Security Facilities Analyses (CIP-014)
  • California-Oregon Intertie Variable Transfer Limits Analyses
