About the company

Luminant generates electricity in Texas and also conducts mining, wholesale marketing and trading, and development activities as part of Vistra Energy. It owns about 17,000 MW of capacity, including nuclear and coal, and buys wind power to supply and balance its portfolio. It differs from competitors by combining a large, diversified generation fleet with active trading, mining, and development under a Texas-focused parent, rather than focusing on only generation or only retail. Its goal is to be a leading competitive energy provider in Texas by owning and operating a broad mix of assets and participating in wholesale markets to deliver reliable power.
