AUSTIN, Texas (AP) — The Texas power grid barely has enough electricity to meet demand this summer, and an unexpected drop in generation or spike in demand could lead to rolling blackouts, the president of the Electric Reliability Council of Texas testified Tuesday.
Trip Doggett told state lawmakers the electric supply will be tight this summer and warned the agency will likely declare Energy Emergency Alerts asking consumers to cut back on use. It may also implement emergency procedures, including taking industrial users offline. But blackouts would only happen if there was an extraordinary drop in generation or the state experienced record high temperatures.
ERCOT is responsible for managing most of the state's electric grid, while private companies generate the electricity. Many of those companies have complained in recent years that Texans don't pay enough for electricity for them to invest in new generation plants. Last month, the Public Utility Commission raised rates to encourage an increase in power generation.
By managing the grid, ERCOT attempts to maintain a 13 percent reserve margin to be ready should demand spike or a generator shut down unexpectedly. But generation capacity has not kept up with population and demand growth, and ERCOT finds it difficult to maintain that reserve capacity in case of an emergency.
