Competitive Power Ventures’ (CPV) Fairview Energy Center, a 1,050-megawatt natural gas AND ethane-fueled combined-cycle electric generating plant in Cambria County, PA, went online ahead of schedule back in December (see CPV Marcellus-Fired Electric Plant in Cambria Goes Online Early). The plant is unique in that it can use both methane AND ethane as a power source–the first and only such plant in the world.
