GO 15


GO15, formerly the Very Large Power Grid Operators Association, is a voluntary initiative of the world’s 19 largest power grid operators (including PJM) representing collectively more than 70 percent of the world’s electricity demand, providing electricity to 3.4 billion consumers on six continents and responsible for integration of 2,518 GW of generation capacity into the grid, of which 21 percent is from renewable energy sources.

GO15 was created in 2004 following several blackouts across the world to investigate fundamental issues of common interest to its members and to develop joint improvement of power system security. PJM was a founding member of the organization in 2004, served as President in 2013, and continues as a member today.
