Key Oregon and Federal Solar Policies 


A variety of local, state, and federal policies guide solar development in Oregon. In many cases, multiple policies support a single solar project. Oregon was an early leader in solar deployment, ranking 9th in the nation in installed solar capacity in 2008. In recent years, however, Oregon has fallen behind. According to the Solar Energy Industries Association, in 2016 Oregon ranked 19th in installed solar PV capacity. 

Solar leadership creates jobs and attracts private investment. By allowing other states to build significant leads in solar development, Oregon has lost many of the advantages that this leadership provides. The state has retained its status at the forefront in solar manufacturing, ranking 5th in the nation in 2015. Many solar components built in Oregon are exported out-of-state, so the manufacturing sector is not as dependent on in-state development as other industries.


Solar + Storage Rebate

January 2020, a new rebate program begins for solar electric systems and paired solar and solar storage systems installed for residential customers and low-income service providers in Oregon. Program funds will be used to issue solar and solar storage system rebates, which are paid to the installing contractor of the system. The rebate amount will be passed on to the customer as savings on the net cost of the system. Rebates may cover up to 40 percent of the net cost for a residential system installed for a customer that is not considered low- or moderate-income, and up to 60 percent of net cost for a low-income customer or low-income service provider.

Net Metering 

In Oregon, homes and businesses may generate and consume solar power produced from onsite solar PV systems. Oregon’s net metering policy allows homes and businesses to offset their retail electricity purchases with solar power produced from onsite solar PV systems. Net metering customers use “bidirectional” electricity meters that run forwards when customers purchase electricity from the grid and run backwards when customers generate solar power. Net metering is one of Oregon’s most essential solar policies because it effectively enables citizens to produce power for their own consumption by offsetting their retail electricity purchases. Approximately 102 MW of distributed solar PV capacity is currently net metered in Oregon.

Energy Trust of Oregon Cash Incentives 

PGE and Pacific Power customers are eligible to receive one-time cash incentives for solar PV installations. ETO incentive values vary by utility and system type and size. Residential customers are currently eligible to receive cash rebates up to $2,8000 per home, and commercial customers are eligible to receive rebates up to $135,000 per business. ETO cash incentives are funded through public purpose charges paid by PGE and Pacific Power customers, and thus are only available for those utilities’ customers. Public purpose expenditures are only authorized to fund the “above-market costs of new renewable energy resources;”  ETO incentive rates therefore decrease over time as solar PV costs decline. ETO cash incentives have supported installation of more than 83 MW of solar PV capacity in Oregon.

Property Tax Policies 

Under Oregon’s Alternative Energy Systems exemption, increases in property values resulting from the installation of onsite “alternative energy systems,” including solar PV systems, are exempt from the property’s assessed value for property tax purposes. More than 5,700 alternative energy projects have received property tax exemptions under this program. The property tax exemption is scheduled to expire in 2023. Through Oregon’s Renewable Energy Development Zone program, solar projects in designated counties may qualify for property tax exemptions for periods of three to five years. Oregon also allows solar project owners to enter into a “fee in lieu of property taxes” agreement with local counties. Under this agreement, the project owner agrees to pay the county $7,000 per megawatt of installed solar capacity on an annual basis for a period up to 20 years. Because the property tax exemption for alternative energy systems only applies to solar arrays that offset onsite electricity use, the payment in lieu of property taxes program helps reduce soft costs for utility-scale solar installations that do not offset onsite electricity use. 

Renewable Portfolio Standard 

Oregon’s Renewable Portfolio Standard (RPS) mandates that 50% of the retail electricity sold by the state’s large electric utilities must come from renewable energy sources by 2040. The utilities demonstrate compliance with the RPS by surrendering Renewable Energy Credits (RECs) that are issued for each megawatt-hour of electricity produced by a qualifying renewable resource. Oregon’s RPS helps create a foundation for solar growth in Oregon by stimulating utility demand for renewable energy. 

Renewable Energy Development Grants

In 2011, the Oregon Legislature adopted a Renewable Energy Development (RED) grant program to incentivize commercial solar development after the expiration of the BETC. However, the RED grant program only provides a limited number of grants for eligible solar installations. Grant recipients are selected through a competitive review process and receive grants representing 35% of total project costs up to $250,000. Approximately 4 MW of solar PV capacity has been installed under the RED Grant program.

Large-Scale Solar Production-Based Incentive 

Until recently, solar PV installations with nameplate capacities between 2 MW and 10 MW were eligible to enroll in a production-based incentive program that allows producers to earn one-half cent per kilowatt-hour of solar power produced by their systems over a five-year period. The program’s enrollment period terminated on January 2, 2017, but enrolled solar producers will continue to earn incentive rates for the remainder of their five-year terms. 

Business Energy Tax Credit (expired)

Until its repeal in 2014, Oregon offered a tax credit for commercial and industrial solar installations. The Business Energy Tax Credit (BETC) program granted businesses tax credits for 50% of eligible project costs, up to a maximum of $10 million per project. Recipients recovered the full credit value over a period of five years. The BETC program supported the installation of more than 36 MW of solar PV capacity in Oregon.

Residential Energy Tax Credit (expired) 

Oregon’s Residential Energy Tax Credit (RETC) offers tax credits of up to $6,000 for residential installations of “alternative energy devices,” including solar PV. The RETC currently provides $1.30 per watt of installed PV capacity and cannot exceed 50% of a system’s total installed costs. The RETC is the only solar incentive available to residences statewide and is a significant driver of residential rooftop installations in the state. Though the RETC is available for multiple alternative energy technologies, it is crucial for solar PV. The RETC program has supported installation of more than 40 MW of solar PV capacity in Oregon. 

Solar Capacity Standard (expired)

Until its repeal in 2016, Oregon’s Solar Capacity Standard directed PGE, Pacific Power, and Idaho Power to collectively procure 20 MW of solar capacity by 2020. The Solar Capacity Standard was repealed through a bill that otherwise strengthened Oregon’s RPS from 25% by 2025 to 50% by 2040. However, Oregon retained the Solar Capacity Standard’s REC multiplier for qualifying in-state solar power. Qualifying solar PV systems located in Oregon that came online before January 2016 therefore continue to earn two RECs for each megawatt-hour of solar power the systems produce.

Solar Volumetric Incentive Rate Pilot Program (expired)

Between 2010 and 2015, Oregon’s Solar Volumetric Incentive Rate (VIR) pilot program offered production based incentives for the output from enrolled solar projects. Participants who enrolled in the program before 2015 earn a set incentive rate for each kilowatt-hour of solar power produced by their systems over a 15-year period. The VIR pilot program was a trial attempt at administering a policy similar to a feed-in tariff, and though the program proved to be more costly than anticipated, it was highly effective at incentivizing solar development in the state in a relatively short period of time. More than 27 MW of solar PV capacity was installed under the VIR program.


Federal Investment Tax Credit (ITC)

The federal ITC offers a tax credit of up to 30% of total project costs for eligible solar projects that commence construction prior to December 31, 2019. In 2020, the ITC phases down to 26%, then phases down to 22% in 2021. In 2022, the ITC will phase down to 10% of project costs. Commercial solar projects that commence construction after 2022 are still eligible to receive a 10% ITC, but the credit is scheduled to expire for residential solar projects at the end of 2022

Public Utilities Regulatory Policy Act (PURPA) 

The federal government enacted PURPA in 1978 to support independent electricity production from “qualifying facilities” (QFs), which include small renewable power producers. 27 PURPA directs utilities to 1) purchase electricity from these QFs, 2) connect the QFs to the electricity grid, and 3) compensate QFs for power purchases at rates that do not exceed the utilities’ own avoided costs.28 Under PURPA, Oregon’s investor-owned electric utilities must enter into contracts to purchase output from qualifying solar power producers at the utilities’ avoided cost rates.
