About the company

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.
