DeKalb County and Georgia Power Landfill Gas Energy Project
- Ellenwood, Georgia
- End User(s):
- Georgia Power Company
- Seminole Road Landfill
- Landfill Size:
- 10 million tons waste-in-place (2009)
- Project Type:
- Reciprocating Engine (two Caterpillar 3520 engines)
- Project Size:
- 3.2 megawatts (MW)
- Environmental Benefits:
- Carbon sequestered annually by 3,100 acres of pine or fir forests, annual greenhouse gas emissions from 2,800 passenger vehicles, or carbon dioxide emissions from 34,200 barrels of oil consumed. Annual energy savings equate to powering 1,900 homes. Estimated emissions reductions of 0.0040 million metric tons of carbon equivalents.

DeKalb County solid waste officials faced a major challenge from county commissioners: Develop a 3.2 MW landfill gas (LFG) energy facility, ensure the county meets all regulatory requirements, and make it a showcase for LFG utilization—plus, complete it on an accelerated schedule without a third-party developer.
Solid waste officials responded with resounding success, earning recognition as LMOP's 2006 Community Partner of the Year. The project met all criteria and was completed on schedule. An innovative design-build-operate procurement approach allowed completion in just seven months from county commissioners' construction approval.
The project's highlights include the following:
- First green power project for Georgia Power.
- Minimum of 22,500 megawatt-hours per year for 10 years.
- Financial payback in less than 5 years.
- Seamless interface with existing flare station and wellfield.
The showcase LFG energy facility emphasizes education and offers tours about LFG utilization. On a 54-inch display screen, visitors view real-time performance of the engine generators. Plus, the facility displays a full circle mural that follows trash from its collection, to the landfill, to LFG generation, to LFG capture, and ultimately to providing electricity to the same residents and businesses from whom the trash was collected.
