Roosevelt signed the Federal Power Act, which gave the Federal Power Commission the power to oversee interstate electricity sales. To understand the history of ERCOT, we should also take a quick look back at the U.S. In the Lone Star State, those prices are set by ERCOT. This cost varies from minute to minute, and in hot climates like Texas, prices are highest in the summer when total demand for air conditioning increases. Energy rates are typically determined by a combination of fuel costs, power plant availability, variations in demand, and availability of generation sources, notes the U.S. Energy Information Administration (EIA) reports that Texas produces more electricity than any other state, and nearly twice as much as Florida, which comes in at second place. It’s no secret that Texas is rich in energy. As a nonprofit, ERCOT is subject to oversight by the Public Utility Commission of Texas and the Texas Legislature. Some 26 million Texans and 90% of the electrical load rely on over 52,700 miles of transmission lines contained within the TIS. Department of Energy, which is responsible for the national energy program, and the Federal Energy Regulatory Commission, which regulates the sale and transmission of electricity in interstate commerce.īut because TIS does not cross state lines, the system can avoid regulation by the Federal Energy Regulatory Commission and is instead managed by the Electric Reliability Council of Texas ( ERCOT). Power grids that cross state lines are managed by the U.S. Texas’ ownership over its power grid is not necessarily for technical reasons, but more for political ones, reported the Texas Tribune in 2011: namely, to avoid the feds. Several smaller interconnections are housed within these larger entities.
power grid is made up of two major and three minor power grids known as interconnections: The eastern and western interconnections are the largest, followed by the Texas, Quebec and Alaska interconnections. TIS spans most of the state and covers all of the electric utilities maintained under the system, each of which is electrically tied together and operates at a “synchronized frequency” of a 60-hertz average during normal system conditions. The Texas Interconnection (TIS) is one of five alternating current (AC) power grids known in north America as interconnections, according to the U.S.
