The Comanche Peak nuclear power plant has significantly curtailed generation at one of its two units in recent days as a result of damage wrought by a thunderstorm Saturday.
It represents an "unusual" situation whereby the Electric Reliability Council of Texas, operator of the power grid serving 75 percent of the state, asked Luminant Generation to reduce electricity generation from Comanche Peak, ERCOT spokeswoman Dottie Roark said Thursday.
As a result of the storm, there was a failed breaker, and it knocked out two transmission lines, Roark said. One of the two large lines could not be returned to service.
"That created congestion on the ERCOT transmission network," Roark said. "So ERCOT operators had to ask Comanche Peak to reduce its output."
The plant’s Comanche Peak One unit scaled back from 100 percent to 76 percent of capacity, Luminant spokeswoman Ashley Monts said. Each of the plant’s two units can produce 1,150 megawatts of electricity.
ERCOT is working with Oncor Electric Delivery, the electric transmission and distribution company serving much of North Texas, to ensure that the failed breaker is repaired, Roark said. Repairs are expected to be completed soon.
Luminant and Oncor are subsidiaries of Energy Future Holdings, the former TXU Corp.
