Landfill gas cogeneration project for US Marine Corps base

21 May 2010 – The US Marine Corps Logistics Base (MCLB) at Albany, Georgia, and Chevron Energy Solutions are to develop the Department of Navy’s first landfill gas cogeneration project, which will produce 1.9 MW of renewable electricity and steam generating capacity by burning landfill gas collected from a nearby landfill site.
 
Chevron Energy Solutions has designed the project and will maintain the landfill gas-to-energy facility, pipeline and landfill gas processing equipment.
 
The new facility will house 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, says Chevron.
 
Chevron Energy Solutions and MCLB will share in the operation of the generator and steam-producing equipment.
 
Through an energy savings performance contract, Chevron arranged the financing for the project, which is repaid through the energy costs avoided. The company also guarantees system performance for 22 years.
 
Chevron Energy Solutions will also complete industrial lighting retrofits in 82 buildings and expand the existing energy management control system. When combined with the cogeneration project, these measures will reduce both the base’s purchase of utility power and carbon emissions.
 
Dougherty County will extract and sell the landfill gas to MCLB from the Fleming/Gaissert Road landfill, which receives approximately 100,000 tonnes of municipal solid waste each year.
 
The biological decomposition of the waste generates landfill gas that is approximately 50% methane gas by volume.
 
‘The project is funded entirely by energy savings and demonstrates how military bases and local governments can work together with private industry to meet federal mandates without increasing taxpayer costs,’ said Jim Davis, president of Chevron Energy Solutions.
