Washington Utilities and Transportation Commission
The customer investment cost recovery incentive payment ("incentive payment") covers the purchase and use of renewable energy systems, such as: solar energy systems, wind generators, and certain types of anaerobic digesters that process manure from cattle into biogas. This program applies to measured customers' renewable energy system kilowatt-hours generated between July 1, 2005, and September 30, 2017.
Any individual, business, or local government that purchases and uses such a system may apply for an incentive payment from the utility that serves the property where the system is or will be located. The utility may make payments to the customer in the form of a credit offsetting the amount the customer owes. The utility then gets a credit on its public utility tax for these incentive payments from the state Department of Revenue.
After September 30, 2017, this program will be administered by the Washington State University (WSU) Energy Program.
First, contact your utility to confirm it is participating in this optional incentive payment program. Ask the utility for a copy of its procedural requirements and application for participating in their incentive payment program. Until September 30, 2017, the utility has the authority to determine whether your incentive payment will be authorized or denied.
Before September 30, 2017, and after contacting your utility, you must apply for a system certification to the state Department of Revenue (DOR). The DOR will consult with the Climate and Rural Energy Development Center at Washington State University's Energy Extension regarding your certification request. The certification form can be downloaded from the DOR website, or may be obtained by calling 1-800-647-7706.
The DOR will notify you in writing within thirty days whether your request for system certification qualifies for the incentive payment program.
After the DOR approves your system's certification, you must apply for your incentive payment from the utility. The utility has sixty days to notify you in writing as to whether your request is authorized or denied. If your utility approves your application, you will have to sign an agreement provided by the utility.
Details of the program are contained in DOR rule: Renewable Energy System Cost Recovery WAC 458-20-273.
