Navy’s first landfill gas power plant completed

The Department of the Navy’s first landfill gas cogeneration plant produces 1.9 megawatts of renewable electric power and steam by burning landfill gas collected from a nearby landfill. Chevron Energy Solutions also completed industrial lighting retrofits in 82 buildings and expanded the existing energy management control system. When combined with the cogeneration project, these measures reduce the base’s purchase of utility power and reduce its carbon emissions by 19,300 tons annually.

Chevron Energy Solutions developed, designed and managed construction of the plant; and will maintain the landfill gas-to-energy facility, pipeline and processing equipment. The facility houses a dual-fuel engine generator, a stack heat recovery steam generator and two dual-fuel boilers. The primary equipment can operate on landfill gas or natural gas, which provides energy security benefits. With the addition of the plant, MCLB’s power portfolio now contains 19 percent renewable power, exceeding guidelines in the EPAct of 2005 and Energy Independence and Security Act of 2007.

Chevron Energy Solutions and MCLB will co-operate the generator and steam-producing equipment. Through an Energy Savings Performance Contract (ESPC), Chevron Energy Solutions arranged the financing for the project, which is repaid through the MCLB’s avoided energy costs. The company also guarantees system performance for 22 years. Chevron Energy Solutions has been actively involved with MCLB Albany’s energy program since 2002, and the base recently won the 2011 Secretary of the Navy Energy and Water Management Award.

Dougherty County extracts and sells the landfill gas to MCLB from the Fleming/Gaissert Road Landfill, which receives approximately 100,000 tons of municipal solid waste each year. The biological decomposition of the waste generates landfill gas that is approximately 50 percent methane by volume.
