About us
A good business neighbor
The Longleaf Energy Hub is being developed by Tenaska, one of the largest private, independent energy companies in the United States. From a five-person operation in 1987 to more than 800 employees today, Tenaska is proud to serve our nation’s energy needs. We remain rooted in Nebraska, and our employees stay true to our founding values of hard work and honest dealing.
Over the past 35+ years, Tenaska has earned a reputation for developing responsible energy projects and being a good business neighbor. We have developed, managed and/or operated more than 23,000 megawatts of natural gas-fueled and renewable generation. Tenaska has been active in Alabama for more than 20 years, dating to the development of two natural gas-fueled power plants in Autauga County.
Today, Tenaska Development is advancing more than 33,000 MW of energy projects, encompassing natural gas, natural gas with carbon capture, energy storage and renewables.
