A former coal mine in western Maryland is now generating solar power – and it’s the largest solar farm in the state. Competitive Power Ventures (CPV) has brought Maryland’s largest solar project online in Garrett County, turning reclaimed coal mine land into a source of clean electricity.
CPV Renewable Power, an affiliate of CPV, and investment partner Harrison Street Asset Management have started commercial operations at CPV Backbone Solar, a 160-megawatt solar project in western Maryland. The site sits on a reclaimed, decommissioned coal mine, turning previously disturbed land into a new source of clean power.
Construction of the project was handled by Vanguard Energy Partners, a solar engineering, procurement, and construction firm.
The project comprises approximately 324,000 solar panels and is expected to generate enough electricity to power around 30,000 homes. For Maryland, it adds new in-state generation while giving former fossil fuel land a second life.
CPV says that the project aims to demonstrate the role of brownfield redevelopment in the energy transition. The company’s CEO, Sherman Knight, said Backbone Solar shows “how brownfield redevelopment, innovative engineering, and strategic partnerships can meet complex project challenges and deliver new power generation in Maryland.”
Local officials have welcomed the project. Garrett County Board Chairman Paul Edwards said bringing the solar facility to the county helps protect the region’s natural landscape while also creating economic value for local residents.
CPV Backbone Solar also includes a community and environmental investment tied to the project. CPV has committed $100,000 over four years to the Deep Creek Watershed Foundation.
Backbone Solar becomes part of CPV’s growing renewable portfolio, which includes four operating wind and solar projects. The company also says it has a 4.8-gigawatt renewable development pipeline.
A second phase of the Backbone Solar project is already under construction. Once completed, it’s expected to increase the site’s total installed capacity from 160 MW to 175 MW.

Oh the irony!
Built on top of an old, depleted coal mine.
