HAGERSTOWN — The largest solar-generating facility in Maryland, capable of powering more than 2,000 homes at peak output, is planned to open in 2012 on 250 acres of state-owned land near the Maryland Correctional Institution-Hagerstown and the Maryland Correctional Training Center.
Maryland Solar LLC of Annapolis announced plans Friday to build the $70 million, 20-megawatt solar facility — a plant that company officials said will be one of the largest on the East Coast and will double the state’s current solar-generation capacity.
The plant would be on a site off Garris Shop and Roxbury roads currently used by a farmer whose lease expires in April 2012, according to Maryland Solar’s application to the Public Service Commission of Maryland.
Maryland Solar is seeking the necessary approvals and trying to secure a long-term lease from the Maryland Department of General Services to begin construction by December to be eligible for a federal renewable-energy tax credit, the application said.
Federal tax credits or cash grants equivalent to 30 percent of a project’s costs were supposed to have expired at the end of 2010, but were renewed, said Jon Moore, executive vice president of Maryland Solar. Moore said he does not think the credits and grants will be renewed for 2012.
Completion of the Maryland Solar Farm, as the project is called, is scheduled for December 2012, with operation beginning soon afterward, he said.
About 125 people will be employed during construction, but Moore said it would take a “relatively small” number of people to run once it is in operation.
Maryland Solar is in discussions with the state Department of Public Safety and Correctional Services about the possibility using prerelease inmates to perform routine maintenance such as landscaping and panel cleaning, a company news release said.
The actual footprint of the plant would not include the entire parcel, said Moore, who estimated that the generating facility would occupy about 150 acres. The number of solar panels needed would be “in the thousands,” and no manufacturer of panels has been selected, he said.
The photovoltaic panels would be mounted close to the ground with screening “to prevent visibility from the closest residential properties,” according to the company’s application. There would be no impact on aviation because there will be no smokestack, and no air or water pollution because there will be no emissions or wastewater or cooling water, the application said.
The solar station will connect to the grid through a substation on an adjacent parcel, so no transmission upgrades will be required, the application said. Maryland Solar has held discussions with Potomac Edison about connecting into the power company’s infrastructure, Potomac Edison spokesman Todd Meyers said.
As part of the approval of the merger of FirstEnergy and Allegheny Power earlier this year, state regulators required FirstEnergy to facilitate the development of renewable-energy projects, Meyers said.
Potomac Edison is a FirstEnergy subsidiary.
