Oregon is the third-largest renewable energy-producing state in the US. The state's energy primarily comes from hydroelectric power, which provides nearly two-thirds of the electricity generated in Oregon. The state also sources energy from coal, natural gas, and wind. Oregon has taken steps towards sustainability, such as enacting the Oregon Renewable Energy Act to reduce reliance on fossil fuels and developing the Wheatridge Renewable Energy Facility to combine wind and solar power with battery storage.

What You'll Learn
Hydroelectric power
The state's abundant hydroelectric resources have made it the third-largest renewable energy producer in the nation. In 2016, Governor Kate Brown reinforced Oregon's commitment to renewable energy by signing the Clean Energy and Coal Transition Act. This legislation mandates a gradual increase in renewable energy sources, aiming for 50% renewable energy by 2040.
The significant contribution of hydroelectric power to Oregon's energy mix is due to the state's geographical features and water resources. The state is home to numerous rivers and dams that facilitate hydroelectric power generation. The Columbia River, for instance, is a significant source of hydroelectric power, with several dams along its course.
One notable example is the Bonneville Dam, which is one of the largest hydroelectric power producers in the region. The dam is located on the Columbia River between Oregon and Washington and has a generating capacity of 1,224 megawatts. Other major hydroelectric facilities in Oregon include the John Day Dam, The Dalles Dam, and the Grand Coulee Dam.
The development and utilization of hydroelectric power in Oregon have been crucial in reducing the state's reliance on non-renewable energy sources, such as coal and natural gas. While natural gas remains the second-largest source of energy consumption in Oregon, the state is actively transitioning towards a cleaner and more sustainable energy future.

Natural gas
Nearly all the natural gas used to generate electricity in Oregon is imported, as there is only one natural gas site in Mist, Oregon, which is primarily used for natural gas storage. Natural gas is typically put into storage during warmer months when prices and demand are low, and then withdrawn during colder months to meet peak customer heating demands. However, natural gas withdrawals also occur at other times to meet the needs of electricity suppliers as they balance intermittent generation.

Coal
In 2019, almost 40% of Oregon's electricity came from coal-burning power plants, with Pacific Power's coal-fired plants being the primary contributor. The Boardman coal-fired plant, in particular, accounted for 15% of the power provided by PGE, Oregon's largest electric utility. Additionally, PacifiCorp, another major electricity provider in the region, relied on coal-fired boilers at multiple locations outside of Oregon, including Montana, Wyoming, Utah, Arizona, and Colorado.
However, Oregon has taken significant steps to reduce its dependence on coal. In 2016, Governor Kate Brown signed the Clean Energy and Coal Transition Act, mandating an increase in renewable energy sources, with a target of 50% by 2040. As a result, Oregon's last coal-fired power plant was closed in 2020, and the state no longer has any active commercial coal mines.
By 2024, coal's contribution to Oregon's in-state net generation had decreased to 5%. While limited amounts of coal were still being shipped to Oregon for use in industrial plants, the state's focus has shifted towards renewable energy sources, including hydroelectric power, natural gas, wind, solar, biomass, and geothermal power.
Oregon's renewable energy portfolio standard and the Clean Energy Targets bill further emphasize the state's commitment to reducing greenhouse gas emissions and transitioning to cleaner energy sources.

Wind power
Oregon has large wind energy resources, and the state has completed many wind power projects, most of them in rural Eastern Oregon and near the Columbia River Gorge. Wind power accounted for 7.01% of the electricity consumed in Oregon, or 12.1% of the electricity generated in the state in 2016. The state has passed laws to encourage both small and large wind projects, including a net metering law in 1999 that helped promote the installation of small wind power systems.
Oregon ranks among the top ten states with the most wind power installed. In the early 2000s, wind power accounted for just 1% of the state's electricity generation, but this had increased to 12.4% by 2013. In 2009, 691 MW of wind-powered capacity was added, the fourth-biggest increase in the US that year. That year, GE Wind Energy was awarded a $1.48 billion contract to build the Shepherds Flat Wind Farm, an 845-megawatt project using over 300 turbines across 30 square miles of north-central Oregon.
Estimates from the National Renewable Energy Laboratory show that Oregon has the potential to install over 27,000 megawatts of onshore wind power, with an offshore wind potential of 225,000 MW, which would be capable of generating 962,723 million kWh. While wind power remains an important renewable energy resource for the state, particularly for large, utility-scale turbines, market conditions and declining costs have made solar power a more attractive investment for individuals and organizations.

Solar power
Oregon is the third-largest renewable energy-producing state in the US. Hydroelectric power is the dominant source of energy in the state, providing nearly two-thirds of the electricity generated in Oregon. However, solar power is also a significant contributor to the state's energy mix.
The Oregon Community Solar Program offers Oregonians the option to subscribe to sustainable community solar projects. This means that residents can access the benefits of solar energy without needing their own rooftop panels. The program is open to customers of Portland General Electric, Pacific Power, or Idaho Power, and provides subscribers with credits on their utility bills. Households meeting low-income guidelines receive subscription discounts and guaranteed savings.
Additionally, Oregon offers incentives and technical support for individuals and businesses interested in installing their own solar power systems. The Energy Trust of Oregon provides cash incentives and technical support for feasibility studies and construction projects that generate renewable energy. Federal tax credits and incentives for income-qualified homes can reduce the cost of installing solar by about one-third.
