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
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.
