Naval Facilities Engineering Command (NAVFAC) has awarded a $170 million, 23-year energy savings performance contract to Constellation, a subsidiary of Exelon Corp, (NYSE: EXC), for an energy conservation and distributed generation project at the Marine Corps Logistics Base (MCLB) in Albany, Ga.
The parties said Oct. 27 that this project includes the installation of an 8.5-MW biomass-fueled, steam-to-electricity (STE) generator, high-efficiency transformers, lighting and boiler upgrades, as well as system controls for a landfill gas electricity generator and centralized monitoring and operation of electricity generation and distribution for the base.
With the added generation and conservation measures MCLB Albany officials estimate it will reduce the total annual electrical consumption by 15% (7,200 megawatt-hours) annually. This means the base will achieve ‘Net Zero’ status as it will be an energy-efficient installation where the annual energy demand will be fully met by renewable energy produced on site.
Marine Corps Logistics Base Albany’s newest energy project is the result of nearly five years of planning and collaboration among the Marine Corps, NAVFAC, Procter & Gamble (P&G), Constellation, Georgia Power, the Georgia Public Service Commission and the Albany-Dougherty Payroll Development Authority.
The logistics base is comprised of 3,600 acres, nearly 400 facilities and Marine Corps-owned and operated utility systems, to include 61 miles of electrical distribution, 19 miles of natural gas distribution, 87 miles of storm water, waste water and potable water lines.
Key to the project’s success is the availability of renewable energy steam supply to power the STE generator plant. Marine Corps Logistics Base Albany will purchase steam from a 50-MW biomass plant located at P&G’s neighboring facility. In 2015, P&G contracted with Constellation to build, own and operate the cogeneration plant which will supply 100% of the steam for P&G’s paper manufacturing facility and generate electricity for Georgia Power.
“Constellation is proud to support the U.S. Marine Corps’ energy and environmental goals and MCLB Albany’s efforts toward achieving net-zero energy use,” said Constellation Senior Vice President of Distributed Energy, Gary Fromer. “This is a public-private collaborative effort that will improve energy security and sustainability for MCLB Albany and P&G, while providing significant cost savings through energy intensity reductions and increasing the use of renewable energy in this community.”
Rick McLeod, Vice President for P&G Product Supply, Global Family Care, added, “P&G originally partnered with Constellation and Georgia Power to help increase the amount of renewable energy used in manufacturing Bounty and Charmin. The onsite biomass facility will utilize locally abundant waste wood to produce 100 percent of the steam needed for one of P&G’s largest global facilities. We welcome the opportunity to share additional renewable steam with our neighbor, helping MCLB Albany become the first Marine Corps installation to reach Net Zero.”
Previous MCLB Albany energy projects include a 1.9-MWlandfill gas-to-energy generator, light-emitting diode (LED) street lighting, solar arrays and a solar hot water heating system. One of the base’s largest projects has been the replacement of the conventional chiller, cooling tower and boiler HVAC system for the Marine Corps Logistics Command headquarters building and installation of the nation’s first underground borehole thermal energy storage systems.
DCO Energy LLC, a leader in the development of central energy centers, combined heat and power facilities, landfill gas-to-energy and biomass projects will provide engineering, procurement and construction services to Constellation for the MCLB Albany project. Schneider Electric will supply and install system controls. Construction is scheduled for completion in 2018.
