The owners of what was once Pennsylvania's biggest coal-fired power plant said Wednesday that they will turn it into a $10 billion natural gas-powered data center campus designed to capitalize on the fast-growing energy demands of Big Tech companies to power artificial intelligence and cloud computing applications.

At a cost of $10 billion, the former Homer City Generating Station will have seven gas-fired turbines to power data centers.

The owners of a retired Pennsylvania coal plant are converting it into the nation’s largest gas plant to power data centers, giving a boost to fossil fuels in one of the central energy-producing regions of the country.
