Under legislation (H.F. 590) the renewable energy tax credit in Iowa was amended to increase the nameplate generating capacity requirement for certain facilities that qualify. It also limits the amount of nameplate capacity that may be allocated to one facility. Except for wind energy conversion facilities, all other facilities must have less than 60 megawatts of nameplate capacity, or energy production capacity equivalent, to apply for the renewable energy tax credit. Prior to the new measure, nameplate capacity could not surpass 5 megawatts for these facilities. The bill was signed into law on July 18 and took immediate effect.
