Austin, Texas - March winds brought a new wind power record to theElectric Reliability Council of Texas
(ERCOT) region Wednesday evening, March 26, when instantaneous output reached a record 10,296MW at 8:48 p.m.
At the time the new record was set, wind generation was providing nearly 29% of the 35,768MW of electricity being used on the ERCOT grid. The new record beats the previous record set earlier this month by more than 600MW, and the American Wind Energy Association reports it was a record for any U.S. power system.
Of the total generation at the time, 1,433MW came from wind generators on the Gulf Coast, while 8,863MW came from other regions. Most came from West Texas, where transmission projects in the Competitive Renewable Energy Zones were recently completed to transport more power from that region to more populated areas of the state.
One MW is enough electricity to power about 200 homes during periods when electric use is highest and about 500 homes during mild weather when less electricity is being consumed.
"With the continuing growth in wind generation capacity and the completion of new transmission projects to get it to the grid, ERCOT is making greater use of this resource, “ said Ken McIntyre, ERCOT’s vice president of Grid Planning and Operations.
Texas continues to have more wind power capacity than any other state. The ERCOT region has more than 11,000MW of commercial wind power capacity, with nearly 8,000MW of new projects in development and more than 26,700MW under study. Wind power comprised 9.9% of the total energy used in the ERCOT region in 2013, compared to 9.2% in 2012.
Wind generation had already broken previous records twice this month. Additionally, 9,868MW of wind generation was serving a record 38.43% of the 25,677MW systemwide demand at 3:19 a.m. on Thursday, March 27.
