Wildfires can affect hydropower facilities by altering water quality and timing of runoff. Forest restoration efforts can mitigate these damaging effects and result in more water supply—further benefiting hydropower by increasing the total potential revenue from water power generation. But it is challenging to accurately estimate the value of added water supply from forest restoration efforts for hydropower facilities. 

Researchers from Blue Forest Conservation, University of California Davis, and The Nature Conservancy simulated the effects of forest restoration in a California reservoir system and found that it could increase average annual water runoff to rivers in the watershed. That additional water supply would boost hydropower electricity generation and potentially increase revenue equivalent to 8-15% of the initial forest restoration costs. It’s an example of how improving the valuation of power and non-power hydropower services would have benefits for hydropower and beyond.

Long-lived hydropower infrastructure must be kept well-maintained and periodically modernized to ensure functionality and safety—particularly in the face of altered rainfall patterns and flood risk due to climate change. To inform emergency and safety planning in the state of California, a consortium of researchers funded by the Yuba Water Agency, California Department of Water Resources, and the National Science Foundation developed ARkStorm 2.0, which simulates possible 1000-year extreme storm and flood scenarios. Based on historic megastorm events in California, ARkStorm 2.0 also incorporates the effects of climate change and advanced climate and hydrological science to improve simulations of these possible weather events. The information in ARkStorm 2.0 about extreme storm and flood scenarios can help inform dam safety investments and emergency planning, to prepare for extreme weather events that can lead to spillway damage, downstream erosion, and even dam failure.

The Salmon in the Classroom curriculum, sponsored by the Benton Conservation District (BCD), is an annual program in which fourth and fifth grade students across eastern Washington raise fish in the classroom. The curriculum culminates in the release of the fish into the Columbia River during the Salmon Summit, where students learn about fish passage, hydropower, and related careers. With support from the Department of Energy Water Power Technologies Office, researchers from the Pacific Northwest National Laboratory (PNNL) partner with BCD bring the latest science on hydropower and fish passage to thousands of students in person and via live stream, including live demonstrations of juvenile salmon tagging and release. 

The educators involved in Salmon in the Classroom are also invited to participate in PNNL’s Teacher-Scientist Partnership—a professional development opportunity for educators to work directly with PNNL researchers and staff to tackle real-world scientific challenges. The program aims to help teachers take real-world problems and lessons—in this case about hydropower—back to their students to inspire the future workforce.

River infrastructure, such as locks and dams, alters water flow patterns in ways that can affect river species and habitats. The Sustainable Rivers Program is a collaborative effort between the U.S. Army Corps of Engineers and The Nature Conservancy to find sustainable ways to manage river infrastructure and water flows that maximize benefits to both people and nature. Specifically, the program helps determine environmental flow requirements for rivers—the water flow on either side of a dam necessary to support river species and habitats—and operating plans for infrastructure that use these flows. The program takes a collaborative approach that combines science and stakeholder engagement to review new environmental flow patterns and modernize river infrastructure. Since 2002, the Sustainable Rivers Program has grown to include 44 rivers and 90 associated reservoirs and dams.

Navigating federal and state energy regulations and permitting can be a complicated process for developers and regulators, which can slow investments in energy projects. Launched in 2015, the Regulatory and Permitting Information Desktop (RAPID) toolkit is designed to help make it easier to navigate the regulatory processes for hydropower, geothermal, solar, and bulk transmission. Specifically, the free toolkit: 

• offers easy access to permit applications, processes, and manuals
• outlines regulatory requirements and clarifies the permitting process
• provides best practices, case studies, and how-to information
• facilitates communication among stakeholders

Since 2015, the toolkit has been accessed from all over the United States by users at federal agencies, universities, state and local governments, utilities and developers, and consultants. Hydropower stakeholders can also provide input to continue improving the toolkit over time and keep it updated. RAPID was developed by the National Renewable Energy Laboratory with funding from the U.S. Department of Energy Office of Renewable Energy and the Office of Electricity, with additional support from Tetra Tech, Environmental Management and Planning Solutions Inc., Kearns and West, and Herrick Solutions.

Economics is a key driver behind the mix of energy sources contributing to the U.S. electric grid. The market value of different energy sources—such as hydropower, solar, wind, or fossil fuels—can determine how competitive they are on the power market. But it is a challenge to accurately estimate the value of hydropower grid services because some of hydro’s key attributes—flexibility and reliability—aren’t included in traditional valuations. To better reflect hydropower’s value, researchers from the Electric Power Research Institute simulated different energy and operating scenarios in the Western Electric Coordinating Council (WECC) region, which encompasses the western United States and parts of Canada and Mexico. With funding from the U.S. Department of Energy to quantify the value of hydropower in the electric grid, this research established the many value streams available to hydropower and identified opportunities to better assess the value of the full range of services that hydropower provides.
