ERCOT, which became the first ISO in the U.S. 20 years ago, also marked its 15th anniversary as the single control area for the state’s competitive market and the 75th anniversary of the Texas Interconnected System, when the state’s utilities banded together to ship power to the shipyards and refineries on the Gulf Coast during World War II.
