Most recently, a broad, nonpartisan coalition of 369 members, including manufacturing, farm and business interests, issued a letter endorsing a four-year extension to the Production Tax Credit (PTC), wind energy's key federal tax incentive. Legislation recently introduced by Representatives Dave Reichert (R, WA-08) and Earl Blumenauer (D, OR-03) seeks to grant a four-year extension to the existing PTC for wind energy (H.R. 3307, the "American Renewable Energy Production Tax Credit Extension Act").
