Unfortunately, we knew this was coming. The wildly generous wind production tax credit that provides 2.3 cents/kilowatt-hour of energy during the first ten years of a project’s operation, as well as the investment tax credit worth up to 30 percent of the costs of developing wind turbines, have been allowed to lapse multiple times over the years, only to be resurrected — zombie-like — shortly thereafter. The well-monied wind lobby has its hands full with the industry-wide freakout that ensues every time the tax credits near their expiration dates, since wind energy is so thoroughly reliant on federal special treatment for survival, and credits’ expiration at the end of 2013 resulted in a whole lotta’ wind project proposals making it in under the wire during last year’s fourth quarter.
