State Incentive Programs: Washington
Renewable Energy Production Incentives
In May 2005, Washington enacted Senate Bill 5101, establishing production incentives for customer-generate solar electricity. The incentive rate paid includes multipliers for systems with components manufactured in Washington State, and thus payments can range from $.15 to $.54 per $0.54/kWh, capped at $5,000 per year. Ownership of the renewable-energy credits (RECs) associated with generation remains with the customer-generator and does not transfer to the state or utility.
In 2009, the passage of Washington SB 6170 extended the production incentive program to Community Solar Projects. Community solar projects are defined as solar energy systems owned by local individuals, households, nonprofit organizations, or non-utility businesses that are placed on local government property; or utility-owned systems funded voluntarily by ratepayers in exchange for a payment or utility credit for electricity produced. This legislation also allows projects on local government property that are owned by limited liability companies, cooperatives, or mutual corporations or associations to receive the incentive.
The incentive payments for community solar participants, starting with a higher base rate and using the same multipliers as mentioned above for Washington-made equipment components, range from $.30 to $1.08 per kilowatt hour. Each participant in the community solar project can apply to receive this incentive and may receive up to $5,000 per year.

Sales and Use Tax Exemption
Equipment used to generate solar electricity and the labor and services required to install these systems are exempt from sales tax in Washington State. From July 1, 2011 to June 30, 2013, the exemption has been reduced from 100% of the sales and use tax to 75% of the sales and use tax. Purchasers of systems larger than 10 kW must claim the exemption in the form of a remittance.
