Cogeneration plant will increase energy security and reduce greenhouse gas emissions at new Department of Homeland Security campus

Washington Gas and Honeywell have been selected by the U.S. General Services Administration to jointly design, install and maintain a central utility and cogeneration plant and distribution system at St. Elizabeths West Campus in Washington, D.C.

Washington, D.C. and Minneapolis, January 6, 2010—Washington Gas (NYSE: WGL) and Honeywell (NYSE: HON) have been selected by the U.S. General Services Administration (GSA) to jointly design, install and maintain a central utility and cogeneration plant and distribution system at St. Elizabeths West Campus in Washington, D.C. The plant will meet up to 30 percent of the peak energy demand for the campus, which will serve as the U.S. Department of Homeland Security (DHS) headquarters as well as its agencies: the U.S. Coast Guard, Federal Emergency Management Agency, Immigration and Customs Enforcement, Customs and Border Protection and Transportation Security Administration. As a result, it will improve energy security, minimize stress on the local electrical grid and reduce greenhouse gas emissions.

The central plant will give GSA the flexibility to support the energy needs of DHS through onsite generation that will deliver nearly 25 MW of electricity for the 4.5-million-square-foot campus that is scheduled to be completed by 2016. The plant and distribution systems will provide thermal utilities, chilled and hot water, electrical services, and normal and emergency power for DHS and its agencies.

The project will have a positive environmental impact because onsite power generation is more clean and efficient than traditional sources. Compared to buying all the electricity from the grid, the new plant is expected to reduce emissions by more than 50,000 metric tons of carbon dioxide equivalent.
