For the fourth time this month, ERCOT broke the all-time record for the most electricity demand on the grid on Thursday and deployed some reserve generation units to in order to keep up.

By the afternoon, Texans were using 76,592 megawatts of electricity, up from the previous record of 76,566 megawatts used Monday afternoon. One megawatt is enough electricity to power about 200 homes on a hot summer day.

Officials had estimated demand on Thursday could have reached nearly 77,900 megawatts, although they had overestimated demand several other times this month.

ERCOT, overseen by the Public Utility Commission of Texas, has been operating in a more conservative manner in efforts to stave off tight grid conditions like might be seen later today. Its independent market monitor has estimated the grid manager has likely spent more than half a billion dollars through May buying more reserve power and changing its operations to bring more power online sooner in tight grid conditions.

Those conservative operating measures could cost $1.5 billion this year, the market monitor estimated in testimony to a Texas House of Representatives committee on Wednesday.

ERCOT officials said Thursday they had enough power to keep up with demand. They have not issued any conservation notices, but Reliant and Green Mountain Energy, two of the state's largest electricity retailers, sent their customers an email late Thursday asking they conserve power through Friday during peak hours.
