Danbury-based FuelCell Energy has signed a power purchase agreement with the Connecticut Municipal Electric Energy Cooperative to supply power to the U.S. Navy Submarine Base in Groton. 

Cooperative CEO Drew Rankin says the project will ensure the U.S. Navy has long-term, cost effective power delivered on the Base for critical infrastructure. 

Captain Paul Whitescarver, the commanding officer of the submarine base, says energy expenses are the single largest cost for Navy installations.  It's about 28 percent of Navy's shore budget.  The fuel cell plant is part of a multifaceted plan to provide new power resources and support the Department of Defense's request to add resiliency and grid independence to key military installations.
