State and local celebrated the commissioning Thursday of what’s been dubbed the first “Marcellus Shale” power plant.

The Liberty Power Plant in Bradford County is one of three natural gas plants being built in Pennsylvania by Panda Power Funds, a private equity firm based in Dallas, Texas. The company plans to commission its sister plant, the Patriot, in Lycoming County November 16. Both 829 megawatt plants came online in July and can provide enough power for up to 1 million homes.

“Both plants were specifically put where they are because of the proximity to the Marcellus Shale,” says Panda Power Funds spokesman Bill Pentak.
