Savannah River Site

Senior officials from the U.S. Department of Energy (DOE), and Ameresco, Inc., gathered for a ceremonial ground-breaking to mark the start of a new project for a biomass heating plant that will increase critical steam security and provide additional green power at DOE’s Savannah River Site (SRS).

The new biomass plant represents a subsequent modification (Phase II) to DOE’s original Energy Savings Performance Contract (ESPC) executed in 2009 for construction of the 20 MW biomass cogeneration facility currently operated and maintained by Ameresco at SRS.

US Representative Joe Wilson told the gathering, “This new facility will produce a steady and reliable source of steam for SRS, provides essential support to the ongoing critical national security and environmental clean-up missions, and will create 50 construction jobs in the process.”

The heating plant will include a new biomass fuelled boiler and relocation of the existing package boiler to a new enclosed building.  Ameresco also will install a new truck tipper and fuel handing system to facilitate the biomass deliveries. The steam produced from the new plant will be supplied throughout SRS’s existing distribution system.  Providing steam from this new plant, will allow for the existing biomass cogeneration facility to direct more steam to the turbine generator resulting in approximately 3-4 MW of additional power for SRS. 

Under the ESPC modification, Ameresco will provide turnkey Operations and Maintenance (O&M) services for the new plant and equipment over the 20-year performance period of the contract. Ameresco also will purchase additional woody biomass from local and regional providers to support the new plant’s operations.  Construction on the project is expected to begin in June, and the plant is scheduled to be operational in the spring of 2016.
