The U.S. Department of Energy and the North Carolina Solar Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in the summer of 2014. Staff are currently working hard on the new DSIRE and are unfortunately only able to make minimal updates to the DSIRE website at this time. We apologize for any inconvenience and thank you for using DSIRE.

In May 2005, Washington enacted Senate Bill 5101, establishing production incentives for individuals, businesses, and local governments that generate electricity from solar power, wind power or anaerobic digesters. The incentive amount paid to the producer starts at a base rate of $0.15 per kilowatt-hour (kWh) and is adjusted by multiplying the incentive by the following factors:

  • For electricity produced using solar modules manufactured in Washington state: 2.4
  • For electricity produced using a solar or wind generator equipped with an inverter manufactured in Washington state: 1.2
  • For electricity produced using an anaerobic digester, by other solar equipment, or using a wind generator equipped with blades manufactured in Washington state: 1.0
  • For all other electricity produced by wind: 0.8

These multipliers result in production incentives ranging from $0.12 to $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 May 2009, Washington passed SB 6170, effective July 1, 2009. With the passage of this legislation, community solar projects are able to receive the production incentive. Community solar projects are defined as solar energy systems up to 75 kilowatts (kW) that are owned by local entities and placed on local government property or owned by utilities and funded voluntarily by utility ratepayers. The legislation excludes utility-owned projects from receiving the production incentive if the utility has annual sales greater than 1,000 megawatt-hours (MWh). In June 2009, the Department of Revenue clarified this exclusion, stating that utility-owned community solar projects that are voluntarily funded by rate-payers are eligible for this production incentive. This ruling was formalized with the passage of SB 6658 in March 2010. 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 company itself is not eligible, but owners may take advantage of the incentive. The base rate for community solar projects is $0.30/kWh and the multipliers are the same as those used for other renewable energy technologies. The actual production incentives range from $0.30/kWh to $1.08/kWh, as the incentive rate is higher for modules and inverters manufactured in Washington. The incentive is capped at $5,000 per year. Each participant in a community solar project, or each owner of a project, can apply to receive this incentive and may receive up to $5,000 per year.

The state's utilities will pay the incentives and earn a tax credit equal to the cost of those payments. SB 6170 also increased the tax credit that utilities may claim for awarding production incentives. Previously, the credit could not exceed the greater of $25,000 or 0.25% of a utility’s taxable power sales. Now, the credit cannot exceed the greater of $100,000 or 0.5% of a utility’s taxable power sales. Incentive payments to community solar projects cannot exceed 25% of the total allowable credit. The incentive amount may be uniformly reduced if requests for the incentive exceed the available funds.

The incentives apply to power generated as of July 1, 2005, and remain in effect through June 30, 2020. A utility may not claim any tax credits for incentive payments after June 30, 2021.
