Entegra Power Group was formed in June of 2005 as an independent power company having ownership interests in two of the largest independent power plants in the United States – the Gila River Power Station and the Union Power Station. These two power stations are similar in size and design and each station is home to four natural gas fired combined cycle facilities that can produce approximately 2,200 MW of power. The Gila River Power Station is located just south of Phoenix, Arizona and the Union Power Station is located in southern Arkansas. In addition, Entegra owns and operates the 42 mile Trans-Union Interstate Pipeline, which flows gas from Louisiana to the Union Power Station in Arkansas. Entegra personnel, located onsite at each of the power stations, perform power plant operations and maintenance.

Entegra’s corporate headquarters is based in Tampa, Florida. The Tampa headquarters is also home to the asset management team that includes an energy marketing and trading organization, which manages all of the commercial energy activities associated with the Entegra energy assets.
