• 1965
    A major electric blackout occurs, affecting 30 million customers in the northeastern United States and southeastern Ontario, Canada.
  • 1967
    The U.S. Federal Power Commission's Prevention of Power Failures report recommends the formation of a power coordination council - made up of representatives from each of the nation's regional coordinating organizations - to exchange and disseminate information on regional coordinating practices to all of the Regions, and to review, discuss, and assist in resolving matters affecting interregional coordination. – Legislation proposed: Electric Power Reliability Act of 1967
  • 1968
    12 Regions and area organizations form the National Electric Reliability Council (NERC) in order to create a central clearing house of lessons learned and identify and share common issues across the Regions.
  • 1970
    SERC_Map_1995 Four organizations in the Southeast - the CARVA Pool, Tennessee Valley Authority (TVA), Southern Company, and the Florida Electric Power Coordinating Group - combine to form SERC. The Region is divided into four subregions – TVA, Southern, VACAR, and Florida. The growth of SERC results in a reduction to nine Regions for NERC. SERC establishes its original headquarters in Birmingham, Alabama.
  • 1981
    To recognize the Canadian membership in the Regions, NERC changes its name to North American Electric Reliability Council, keeping the acronym NERC.
  • 1984
    SERC relocates its headquarters to Chattanooga, Tennessee. The staff remains small and all technical work is performed by committees and subcommittees, consisting of subject matter experts across SERC's member companies.
  • 1994
    SERC's headquarters returns to Birmingham, Alabama.
  • 1996
    Certain SERC member companies located in Florida, formerly represented by the Florida Electric Power Coordinating Group, form the Florida Reliability Coordinating Council (FRCC) and separate from SERC.
  • 1996
    SERC grows as a result of Entergy, Associated Electric Cooperative, and Louisiana Generating, LLC (formerly CAJUN Electric Power Cooperative) becoming official members of SERC, adding a fourth subregion (Entergy subregion) to SERC.
  • 2003
    The worst North American electric blackout to date occurs, affecting 50 million customers in the Northeastern and Midwestern United States and in Ontario, Canada.

    A joint United States-Canada Power System Outage Task Force is formed to investigate the causes of the blackout and to make recommendations to prevent future blackouts.
  • 2004
    The United States-Canada Power System Outage Task Force issues its report on the 2003 blackout.  It concludes that the single-most important recommendation for preventing future blackouts, and reducing the scope of those that occur, is to make Reliability Standards mandatory and enforceable.

    In response, NERC translates its operating policies, planning standards and compliance requirements into an integrated and comprehensive set of 90 measurable standards called “Version 0 Reliability Standards.”
  • 2005
    SERC officially incorporates as SERC Reliability Corporation and Version 0 Reliability Standards become effective.
  • 2006
    NERC is certified as the Electric Reliability Organization (ERO) in the United States, pursuant to Section 215 of the Federal Power Act.  As the ERO, NERC delegates authority to SERC and seven other Regions to ensure the reliability and security of the electric grid across North America. The Federal Energy Regulatory Commission (FERC) approves the delegation and officially authorizes SERC to perform this important responsibility across its footprint.
  • 2006
    SERC continues to grow and its footprint expands as a result of several members in the central part of the country joining SERC. This results in the creation of a fifth subregion within SERC. The names of the subregions are changed to Central (formerly the TVA subregion), Delta (formerly the Entergy subregion), Gateway (newly added), Southeastern (formerly Southern subregion), and VACAR.
  • 2007
    As a result of its continued growth and expansion, SERC relocates its headquarters to Charlotte, North Carolina.
  • 2017
    To better align studies, assessments, and reporting with the existing Planning Coordinator boundaries, SERC redefined the subregions to: MISO-Central (previously the Gateway subregion), MISO-South (previously the Delta subregion), Central, East (previously part of the VACAR subregion), Southeastern, and PJM (previously part of the VACAR subregion).
  • 2018
    On July 1, 2018, SERC's membership grows and its footprint expands west as a result of 13 Registered Entities transferring from the dissolved SPP Region to SERC.
  • 2019
    201907_Subregions_1000x954On July 1, 2019, SERC’s membership grows and its footprint expands south to include all registered entities in the state of Florida. Entities transferring to SERC from the former FRCC Region created a seventh SERC subregion: FL-Peninsula.
