Environmental Record

Independent power projects developed by Tenaska are sited, designed, constructed and operated to comply with all applicable environmental standards. Tenaska generating facilities are recognized in the industry for efficiency, state-of-the-art technology and superior emissions performance.

Tenaska’s highly efficient natural gas-fueled power plants are extremely low emitters of conventional and greenhouse gas pollutants. The Tenaska Ferndale Cogeneration Station was one of the first to adopt selective catalytic reduction to control nitrogen oxide emissions.

The Natural Resources Defense Council (NRDC), an environmental organization, has listed Tenaska in benchmarking studies since 2004 as having among the lowest fleet-wide average emission rates for fossil-fueled power plants in the United States.

The company continues to grow its renewables business. Tenaska has two utility-scale solar power plants in Southern California’s Imperial Valley. Together, the Tenaska Imperial Solar Energy Center South and the nearby Tenaska Imperial Solar Energy Center West are able to generate enough power for 99,000 homes in the San Diego area.

Tenaska employee-owners are investing in wind power through the Elkhorn Ridge Wind Farm in Nebraska, and the company’s Strategic Development & Acquisitions team has a number of wind projects in advanced development.

Preservation of wetlands, cultural resources and endangered wildlife and plants is built into every Tenaska project. For some projects, Tenaska has coordinated with local agencies, identifying opportunities to restore degraded wildlands. For example, Tenaska worked with the Sabine River Authority of Texas, the Texas Department of Parks and Wildlife, the U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service to restore forested wetlands in Shelby County, Texas, helping to sustain the efforts of these agencies to expand habitat for Wood Duck and other sensitive wildlife.

Tenaska works with communities to find environmentally responsible solutions, from site landscaping to protection of wildlife habitats and conservation and re-use of water. The Tenaska IV Texas Partners plant near Cleburne, Texas, was one of that state’s largest water re-use projects when it went online in 1997, using the town’s wastewater for plant cooling, and the Tenaska Frontier Generating Station used its own wastewater to irrigate farmland.

Tenaska was a pioneer in efforts to reduce and offset power plant emissions of carbon dioxide, considered by many to contribute to global warming. As part of those efforts, Tenaska invested in renewable power in Bolivia to displace fossil-fueled electric generation in 2002, restored forests in eastern Washington state in 1994 and donated money to buy and preserve tropical forestland in Costa Rica that was in danger of being deforested in 1990.
