A new incentive program for citizens and businesses of Washington recently passed the Washington State Legislature and was signed into law by the Governor. Engrossed Substitute Senate Bill 5939 modifies tax incentives for renewable energy systems and provides guidance for recycling related components. The WSU Energy Program will begin administering the new incentive program on October 1, 2017. Until then, the Washington State Department of Revenue (DOR) is the administrator of the legacy program, and the WSU Energy Program is working closely with DOR to ensure a smooth transition.
