Decatur Generating Station
Energy production of the Decatur Generating Station is enough to power approximately 1,000 homes.
Decatur Generating Station produces electricity from landfill gas 24 hours a day, 365 days a year. The project’s partners, Granger and the City of Decatur, Alabama, and electric customers, the Tennessee Valley Authority (TVA) and the Joe Wheeler Electric Membership Corporation (EMC), work together to bring renewable energy to local residents.

Granger is the developer and built and operates the electric generating station. The City of Decatur owns Decatur/Morgan County Landfill, which supplies the landfill gas. The TVA, a corporation owned by the U.S. government, provides electricity for 9 million people in parts of seven southeastern states at prices below the national average. The Joe Wheeler EMC is an electric cooperative that provides electricity to Morgan and Lawrence Counties in Alabama, serving more than 33,000 members. Joe Wheeler EMC purchases electricity produced at the generating station, which is provided to Joe Wheeler customers via TVA’s power grid.
Decatur/Morgan County Landfill opened in 1980 and as of 2014 had 3,600,000 tons of waste in place. The 199-acre facility is expected to be in operation for approximately 25 more years; energy production is expected to continue for an additional 20 to 30 years after it is closed.
Decatur Generating Station has been online since 2010. The project uses landfill gas from Decatur/Morgan County Landfill to fuel multiple on-site engine generator sets. These powerful pieces of equipment consist of an 1,100 horsepower engine similar to the engine of a car, only much larger. The engine drives the attached generator, which produces electricity. Decatur uses two engine generator sets with the capacity to produce a total of 1.6 megawatts of electricity.
A small amount of the energy produced at Decatur Generating Station is used directly to supply the generation facility itself, with the majority of electricity being delivered to the utility’s grid to supply local homes and businesses.
