The company said the one-year contract renewal sustains Constellation’s federal supply to 2.7 million MWh of electricity per year, serving almost every region of the country eligible for competitive supply.

Constellation Public Sector and Energy Efficiency vice president Louis Hutchinson said the company welcomes opportunities to meet future clean energy needs such as the GSA solar project in Sacramento.

Constellation’s federal electricity support throughout the nation includes GSA contracts for the US Capitol, Federal Reserve and Smithsonian Institution, as well as agencies in New York, Connecticut, New Hampshire, Rhode Island and Pennsylvania.

Constellation Energy is a federally approved provider of demand response services for both military and civilian government agencies, enabling federal sites to earn money by reducing consumption during times of peak energy demand.
