Vistra (NYSE:VST) said its generation fleet provided 96% commercial availability during Texas’ record-breaking summer, helping smooth the volatility of fuel prices, weather and rising inflation.

CEO Jim Burke told financial analysts during the company’s third-quarter earnings call Friday that its thermal fleet reached maximum capacity on July 13, when wholesale prices reached the $5,000/MWh cap three times.

“A well maintained fleet is key to delivering reliable power for our customers and our communities and ensuring value is captured during these weather events,” Burke said.

Vistra reported quarterly earnings of $1.04 billion as measured by adjusted EBITDA from ongoing operations, as compared to $1.19 billion for 2021’s third quarter. The company uses adjusted EBITDA as a performance measure because, it says, outside analysis of its business is improved by visibility into both net income prepared in accordance with GAAP and adjusted EBITDA.

Burke said management has been pleased with how its Vistra Zero assets performed this summer in Texas and California. It is attempting to extend by 20 years the operating licenses at generation subsidiary Luminant’s Comanche Peak Nuclear Power Plan. That would keep the 2.4-GW plant’s two units operating until 2050 and 2053.

“We continue to see how important a role our diverse set of assets are playing throughout the U.S. and ensuring reliable, affordable and sustainable power,” he said.

The Irving, Texas-based company said its full-year results are tracking at the midpoint of their $2.96 billion to $3.16 billion guidance. It is amid an upsized $3.25 billion share repurchase program, having bought back about $2.05 billion in outstanding shares (18%) as of Nov. 2.

Vistra’s share price lost 40 cents on Friday, closing at $22.85.
