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. The former Homer City Generating Station, about 50 miles (80 kilometers) east of Pittsburgh, will host seven gas-fired turbines to power data centers on site with up to 4.5 gigawatts of electricity, according to the owners, an investor group named Homer City Development. Construction is expected to begin this year and power could start flowing by 2027, the group said in a statement.
