DOE funding projects to increase hydropower flexibility

The US Department of Energy’s (DOE) Water Power Technologies Office (WPTO) has released a $9.5 million funding opportunity to increase hydropower’s flexibility, allowing it to better balance the variability of resources such as wind and solar on the power system.

Hydropower accounts for 28.7% of total US renewable electricity generation and about 6.2% of total US electricity generation. It can supply electricity immediately or store it to meet real-time demand. By enhancing these abilities, this investment helps strengthen hydropower’s ability to support an electric grid with an increasing amount of variable renewable energy resources as the US works to meet its clean energy goals.

The opportunity will fund projects in three topic areas:

• Up to $4 million for projects that demonstrate hydropower hybrid configurations, such as a hydropower facility paired with another type of generation or with an energy storage resource.
• Up to $4 million for projects that advance technology innovations to improve the flexible capabilities of the US hydropower fleet.
• Up to $1.5 million for projects that quantify the flexible capabilities of hydropower and advance operational strategies to increase such flexibility to better serve an evolving electric grid.

Between four and seven awards are anticipated under the Strategies to Increase Hydropower Flexibility funding opportunity. Individual awards may vary between $750,000 and $4 million.

Topic Area 1, Hydropower Hybrids Demonstration, will support demonstrations of hybridised hydropower operations in which hydropower is co-located and co-operated with at least one other non-hydropower generation or storage resource. This topic is motivated by industry insights and previous research suggesting that synergies between hydropower and other resource characteristics can expand capabilities to provide enhanced grid services, reduce machine wear-and-tear, and mitigate environmental impacts.

Topic Area 2, Technologies to Increase Flexibility, will support testing of advanced hydropower components, which will tackle component-level constraints to a hydropower facility’s flexibility. Motivated by industry discussions and targeted technical workshops with manufacturers, this topic builds on previous research to de-risk promising new technologies so they can progress toward widespread deployment.

Topic Area 3, Operational Flexibility, supports development of operational strategies, model enhancements and related tools that can allow individual plants or coordinated sets of plants (e.g., in cascading river systems) to increase their net flexibility. Informed by previous research by academics, national laboratories and other research organisations, this topic will target projects that advance the state of the art while pursuing incorporation of these advancements into actual operational practice in the industry.

Concept papers are due by 5 p.m. ET on 18 Jan 2024, to be eligible to submit a full application. The expected submission deadline for replies to reviewer comments is 23 May 2024. The expected date for DOE selection notifications is August 2024 and the expected timeframe for award negotiations is August to November 2024.
