Pepco Energy Services Inc. and DC Water have signed an agreement for Pepco Energy Services to design, build and operate a Combined Heat and Power (CHP) plant at DC Water’s Blue Plains Advanced Wastewater Treatment Plant (AWTP). The Blue Plains AWTP serves approximately 725sq/mi of DC, Maryland and Virginia and has a capacity of 370 million gallons per day. Pepco Energy Services will design and build the CHP project for USD 81 million, and it will be the first in North America to use biogas from an AWTP facility.
The CHP project will produce at least 14MW of electric power that will supply the Blue Plains facility with nearly 30% of the AWTP’s average power demand. In addition to designing and building the CHP plant, Pepco Energy Services will provide on-site operations and maintenance services valued at more than USD 89 million over the 15-year contract term. The overall project is valued at approximately USD 170 million.

The CHP plant will also include three Solar Mercury 50 low-nitrogen oxide gas turbines, digester gas cleaning and compression equipment, heat recovery steam generators, duct burners, a backup boiler, electrical equipment needed to operate in parallel with the utility grid and ancillary systems, including water treatment and process control systems. Construction will begin in August and is due to be completed in December 2014.
