"If the wind does not pick up, we will have to rely on our on-demand dispatchable generators." "We will continue to use every tool available to keep the lights on and the ACs running this summer, but we do not have any control over wind or sun," Lake said. Lake said there were at least 12 days last summer when wind generation was operating less than 20% during the peak hours of 8 p.m. But, much like last year, there will be days when the wind supply won't be able to keep up with the demand. Some of the threats and concerns highlighted by AccuWeather meteorologists for the upcoming summer season.Īccording to Lake's data, for wind generation to keep up with the power demand on the hottest days this summer, about half of the units need to be generating power by 9 p.m.
"Our solar generation is all gone, so at that point of the day, we will be relying on wind generation." "Our risk goes up as the sun goes down because it's still hot at 9 p.m.," said Lake. In the press conference on Wednesday, Lake highlights a risky "new reality" the power grid in Texas could face this summer. wind energy in 2021," according to a " Review of the Texas Economy," from the Texas Comptroller in September 2022.
"For the last decade and a half, Texas has led the nation in wind-powered electricity generation, producing nearly 26% of the U.S. Wind power also accounted for 25% of Texas's electricity generation in 2022, second to natural gas which accounted for 43%. "So we will be relying on renewables to keep the lights on."ĮRCOT says wind energy (28.6%) is only behind natural gas (48.6%) in terms of generating capacity for 2023 in the state. "On the hottest day of summer, there is no longer enough on-demand dispatchable power generation to meet demand in the ERCOT system," Lake said at a press conference on Wednesday. Lake says that in the same time frame, ERCOT's on-demand dispatchable power supply has grown only 1.5%. According to Texas Public Utility Commission Chair Peter Lake, Texas's population grew 24% from 2008 to 2022, but Texas's on-demand dispatchable power supply hasn't kept up with this growth.
