The US state of Connecticut is planning a naval base microgrid at Groton to ensure power reliability for a naval submarine base.
The facility is estimated to have a capacity of approximately 13 MW and cost over $1 billion.
Off-Grid News reports that the goal of the microgrid is to provide energy security for the Groton base — which houses nuclear submarines and a submarine school — as well as for the critical services in the surrounding community. The microgrid will likely integrate an existing solar array on the base, and also rely on diesel fuel and possibly natural gas and wind.
The state Office of Military Affairs is now identifying a combination of private, state and federal funding for the project, said Bob Ross, OMA’s executive director.
“We want to first provide energy security to the base,” Ross said. “If we lose the larger grid, the base will be able to operate the submarines.” In addition, the microgrid will reduce the base’s operating costs through peak shaving and demand management, he said.
The base and surrounding community have experienced major storms that knocked out power for days, he said.
The base was awarded a $3 million grant from the first round of funding offered through Connecticut’s Microgrid Grant and Loan Pilot Program in July 2013.
The money is funding a 5-MW cogeneration turbine and a 1.5 MW diesel generator to serve various buildings and piers.
