Texas Grid Wind Generation Reaches Record Levels

Texas Wind Power

By Editors of Power Engineering

Officials at the Electric Reliability Council of Texas – managers of 90 percent of the state’s electric load – reported wind generation recently topped 15,000 MW in one day, which was the biggest amount of generation in the region.

Specifically, the ERCOT system used 15,033 MW of electricity from wind at 12:35 p.m. on Sunday, Nov. 27, representing about 45 percent of total demand for electric power at the time. Of the total, more than 8,800 MW was produced from wind generation facilities in West and North Texas, while nearly 3,800 MW came from the South region, mostly the Gulf Coast area, and about 2,300 MW came from the Panhandle region.

"We saw high wind output throughout the day, ranging from just over 10,000 MW during the late night hours to this peak output during the noon hour," said ERCOT Senior Director of System Operations Dan Woodfin. "Over the years, ERCOT has taken a number of steps, such as improving renewable generation forecasts, to allow us to operate the grid reliably on days like this."

The proportion of wind generation averaged 41 percent during the day.

The previous wind generation output record of 14,122 MW was set on Nov. 17. The current record for percentage of load served — 48.28 percent — was set on March 23, 2016, at 1:10 a.m.
