Pepco building US-based biomass CHP plant

A Washington DC, US wastewater treatment plant will generate some of the power required to run itself, after a Pepco Holdings Inc. (NYSE: POM) subsidiary completes its work.

Washington Business Journal reports that Pepco Energy Services has been hired to build and maintain a combined heat and power plant at D.C. Water’s Blue Plains Advance Wastewater Treatment plant.

Pepco will build the project for $81m, and be paid $89m over 15 years for on-site operations and maintenance.

Blue Plains, located in Southwest D.C., will be the first in North America to use biomass from its own wastewater treatment plant. It will produce enough electricity to power about 30 percent of the facility’s electrical needs.

“This project is a major step forward in the way D.C. Water handles its solid wastes,” said Pepco Energy Services CEO John Huffman. “By recycling biogas, we will be able to create electricity and steam to help power then Blue Plains advanced wastewater treatment plant.”

Construction starts in August and is expected to be complete by late-2014.

The Blue Plains advanced wastewater treatment plant is the largest in the world, handling 370 million gallons of sewage a day from the region, and serves about 725 square miles of D.C., Maryland and Virginia.
