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 using Marcellus methane (see CPV Marcellus-Fired Electric Plant in Cambria Goes Online Early). However, the plant is designed to mix ethane in with methane and burn the mix. The new plant completed tests and began blending in Marcellus ethane in March (see ‘First of Its Kind’ Methane/Ethane PA Power Plant Now Online). Why blend? To keep costs down.
