A variety of utilities and governmental bodies in Washington provide 14 solar rebate and incentive programs.

Renewable Energy Sales and Use Tax Exemption

Value:Varies

Most renewable energy systems in Washington state are at least partially exempt from sales/use tax. Qualifying technologies include solar, wind, some biomass, hydroelectric, geothermal, landfill gas, and hog fuel (wood-burning.) Total exemptions are available for hog fuel systems and solar devices rated for less than 10 kW. Other systems will receive a 75% exemption applied at the time of purchase. Exemption certificates are available from the Department of Revenue and must be presented to the equipment dealer.

Renewable Energy Standard

Value:Varies

Washington first established a renewable portfolio standard in 2006 upon the passage of a statewide referendum. The most recent standard goals required at least 15% of each utility's retail electricity to be generated using renewable technology by 2020. Compliance with the standard is measured using a Renewable Energy Credit system pegging one megawatt hour of electricity to a variable dollar amount. Utilities may generate credits using their own renewable facilities or purchase them from customers through tariff programs. Should a utility fail to meet its standard quota, it will be fined for each credit it is deficient. Utilities are exempt from the standard if they do not have load growth or if renewable energy investment would not be cost-effective.

Interconnection Standards

Value:Varies

Distributed generation and interconnection practices in Washington state have been standardized since 2007. All private utilities are subject to the standards; local public utilities and cooperatives are exempt. Each new renewable energy system to be interconnected will be assigned one of three regulatory Tiers. A system's Tier determines the IEEE/UL/NEC standards it must follow and the rigor of the permit process, including application fees and turnaround times. Tier 1 ends at 25 kW, while Tier 2 ends at 500 kW. External disconnect switches are required for systems at or above Tier 2. Utilities may require customers to carry liability insurance or a minimum warranty for their system.

Green Building and Energy Reduction Standards for State Agencies

Value:Varies

Since 2005, new state buildings and public remodeling projects in Washington state have been required to follow certain green building standards. Any new occupied public building at least 25,000 square feet in size must meet the requirements for LEED Silver certification and pursue formal accreditation from the US Green Building Council. Remodeling projects should incorporate as many LEED principles as possible, though they are not required to pursue formal certification. Additional information is available from the Washington Department of Enterprise Services.

Clark Public Utilities - Solar Energy Equipment Loan

Value:Varies

Residential customers of Clark Public Utilities may be eligible for special loans to fund new solar energy systems and components. The maximum available principal per loan is $30,000 at 3.5% APR. The principal determines both repayment period duration and the applicable fees and conditions. Additional information is available from the CPU website.

Grays Harbor PUD - Net Metering

Value:Varies

The Grays Harbor Public Utility District operates a unique net metering program. Credits for net excess generation are awarded at the end of each year and amount to half of the normal retail price. While the Grays Harbor program technically does not follow the letter of the state's net metering laws, customers may earn additional benefits and have a greater incentive to adopt renewable energy. Additional information is available through the utility website.

WSHFC Sustainable Energy Program

Value:Varies

The Sustainable Energy Program/Trust is a division of the Washington State Housing Finance Commission. Residents and businesses undertaking new green construction or making energy efficiency improvements may be eligible for at least $50,000 of special financing. Interest rates of 2 - 4% are available. To qualify, a project should improve the site or entity's energy efficiency by at least 10%. Standard engineering reviews and pre/post-work energy audits apply. Additional information is available from the WSHFC website.

Evergreen Sustainable Development Standard for Affordable Housing

Value:Varies

The Evergreen Sustainable Development Standard is Washington's green building rubric tailored for new affordable housing. Standards are based on LEED and incur points for compliance. Small energy efficiency practices can earn 1 point, using renewable energy (such as solar PV) can earn five points, and exceeding the total standard will earn 15 points. New affordable housing projects should earn at least 50 points; remodeling projects should earn at least 40 points. Additional information and a copy of the standard are available from the Washington State Department of Commerce.

Renewable Energy Manufacturing Program

Value:Varies

Mandatory Utility Green Power Option

Value:Varies

Washington state law requires all public or private electrical utilities with a customer base of at least 25,000 to offer green power options. Customers can purchase 100% renewable energy in fixed blocks. This energy may be derived from solar, wind, biomass, hydroelectric, landfill gas, or a combination of these technologies. Each customer will be notified of the green power option on a quarterly basis. Annual reports on program uptake and resources are available from the state legislature.

Tax Abatement for Solar Manufacturers

Value:Varies

In 2005, former Washington governor Christine Gregoire approved a legislative corporate tax cut for the state's solar energy device and component manufacturers. Current tax rates for these companies are at least 43% below the average liability. Tax incentives only apply to businesses producing silicon components, semiconductors, solar cells, converters, and other components directly involved in the production of photovoltaic energy. The special rates expire in 2027. Additional information is available from the Department of Revenue.

Net Metering

Value:Varies

In Washington, any renewable energy system rated for under 100 kW is eligible for net metering. All public/private utilities and cooperatives must offer interconnection and net metering to new renewable energy customers. Upon agreeing to a net metering contract, the energy system's owner will have a bidirectional meter installed to measure net excess generation (NEG) sent back to the grid. Utilities will credit customer bills for NEG at an avoided-cost rate per kilowatt hour. Should generation exceed consumption for any given cycle, NEG credits may roll forward to subsequent months. Additional information is available from the Washington Utilities and Transportation Commission.
