Dallas -

Luminant's fleet of nuclear, coal and natural gas power plants helped power Texas – and contribute to continued reliability – through today's record-setting demand. All of Luminant's baseload power plant units were available for generation, including two nuclear units, 12 lignite-fueled units, as well as multiple peaking natural gas units.

"We owe a huge debt of gratitude to our highly skilled team of plant and mine employees who are working through challenging conditions to help power Texas,” said Mike Williams, Luminant's chief fossil officer. "Their dedication and professionalism is unparalleled and a significant factor in maintaining continued reliability through today's peak.”

"During times like these reliability is even more critical,” said Rafael Flores, chief nuclear officer. "We're pleased to do our part to keep Texans cool and safe during this heat wave.”
