Wind power in Texas topped 10,000 megawatts for the first time and also set a record for its share of electricity being used, the state’s largest electricity grid said Thursday.
The Electric Reliability Council of Texas said that at 8:48 p.m. Wednesday, wind farms connected to ERCOT’s transmission network generated 10,296 megawatts. That’s enough to power about 5 million typical Texas residences during a period of moderate electricity use, according to the American Wind Energy Association, a trade group.
The previous high was 9,689 megawatts.
The trade group said Wednesday’s peak was the most wind power ever on any regional power grid. The previous high was 10,012 megawatts in November on the Midcontinent Independent System Operator, which serves 11 states and one Canadian province.
ERCOT also said that at 3:14 a.m. Thursday, wind produced 38.4 percent of all the power on its grid, the highest share ever. ERCOT, which serves about 85 percent of Texas’ electricity demand, has more than 11,000 megawatts of installed wind capacity.
