Renewable Energy System Incentive Program

IMPORTANT: Deadlines to Address ESSB 5939’s Funding Limit (10-9-18)

Due to the high level of interest in the Renewable Energy System Incentive Program and the funding limitations prescribed in the governing legislation, we have established the following requirements, which will govern the incentive program's closure.

Be advised that these requirements apply only to the overall $110 million funding limit; there are additional utility-specific funding limitations.

    Residential-Scale & Commercial-Scale Projects

    • Applications must be submitted by 5:00 p.m. on February 14, 2019 and have a final electrical inspection date no later than January 31, 2019.
    • Applications received after February 14, 2019, or that have a final electrical inspection date after January 31, 2019, will be placed on a waitlist and will be processed only if funds are available.

    Community Solar & Shared Commercial Solar Projects

    All eligible sponsors of community solar or shared commercial solar projects must have submitted a precertification application by 5:00 p.m. on November 16, 2018. Applications received after this date will not be considered for funding under the $110 million funding limit.   

    Apply Online for the Renewable Energy System Incentive Program

    Use the online application to apply to the incentive program approved by the Washington State Legislature in 2017. PowerClerk® lets you:

    • Create and submit a new incentive application,
    • Check the status of their application as the review process gets underway.

    For a list of participating utilities, please see the pdf file in the right-hand navigation menu.

    Incentive Payments and Production Confirmation

    WSU is working closely with all 48 participating utilities in Washington to collect production information and calculate incentive payments. Payments will be issued by your utility. No specific dates for payment by any given utility are available.

    Some utilities may send their customers a confirmation of electricity production from participating renewable energy systems. If your utility sent a production confirmation letter and you have questions about this letter, please contact your utility.

    This is the first year WSU and the utilities are working through this new requirement, and we appreciate your patience while we complete this process.

    Submit Application within 30 Days of Final Electrical Inspection (5-14-18)

    As we approach the end of the fiscal year (June 30, 2018), it is crucial that installers and customer-owners submit incentive applications to the WSU Energy Program within 30 days of the final electrical inspection date. If an application is received after this 30-day window, an initial meter read will be required before the system can be certified.

    The consequences of submitting an application beyond the 30-day window include:

    • The customer-owner will not get production credit for the period between the final electrical inspection and the initial meter read.
    • The customer-owner will not receive the incentive rate for FY 2018.

    For example, if a system passes its final electrical inspection on May 1, 2018, but the application is not submitted until July 1, 2018, that system will require an initial meter read before it can be certified. Because that meter read will occur after the application is submitted, the customer-owner will receive the incentive rate for FY 2019 (which starts on July 1, 2018).

    Conversely, if a system passes its final electrical inspection on June 1, 2018, and the application is submitted prior to July 1, 2018, that system would qualify for a FY 2018 incentive rate.

    Date of System Certification (3-30-18)

    To determine the date of system certification, the WSU Energy Program will use the date of final electrical inspection as the date of certification, provided an application for certification is submitted within 30 days of the final electrical inspection.

    Policy Statement: Can Total System Price Include Battery Storage?

    As established in ESSB 5939, Washington’s Renewable Energy System Incentive Program sets out to expand the generation of grid-connected, distributed energy in a fair and equitable manner that encourages broad participation and adheres to the incentive limit of $110 million. Upon review of the legislation, the WSU Energy Program has made a preliminary determination that only the equipment that is necessary and integral to the generation of electricity in a grid-connected renewable energy system can be included in the total system price. Because our emergency rule did not explicitly address this issue, we have approved a small number of applications that include storage and extra equipment in the total system price. The final rule will speak directly to energy storage systems.

    Renewable Energy Cost Recovery Incentive Program

    The reapplication period for previously certified Renewable Energy Cost Recovery Incentive Program recipients ended April 30, 2018. If you have questions or concerns, please send an email to solarprogram@energy.wsu.edu.
