The US power system has undergone a number of changes over the past decade driven in part by increasing penetrations of variable renewable energy, distributed energy resources and grid-scale battery storage, as well as increasing consumer participation and shifting load profiles to name a few. These changes are anticipated to continue in the coming decade and beyond, likely accompanied by others—technological, socio-political, and market-oriented—that may substantially change the operational requirements of the power grid. The varying degrees to which these changes manifest will drive changes in the value that hydropower resources can provide to power systems. Many hydropower resources have technical capabilities to provide a range of grid services that have traditionally been largely untapped due to either low system requirements for these services, or a lack of clear price signals for the value that they provide to the grid. We will establish a framework for quantifying the system value generated by conventional hydropower and PSH through the provision of grid services, as well the system factors that may augment these value streams in the future as power systems continue to evolve. The outcomes of this work will help stakeholders make prudent decisions regarding changes in operating practices and directing capital investments to improve resources' abilities to provide various grid services.

Value of flow forecasts to power system analytics

Lead Researcher (s)
- Nathalie Voisin
This project will use inflow forecast, reservoir and power system model simulations, and case studies to practically demonstrate where forecast improvements would create the most value for hydropower services. This research will benefit utilities and other hydropower operators who utilize flow forecasting to support water management and electricity production; it will also support DOE in targeting future investments related to forecasting that will benefit these groups.

Value of flow forecasts to power system analytics [HydroWIRES]

Hydropower operators use weekly water inflow forecasts to optimize reservoir releases and unit commitment and to meet power grid needs. The accuracy of inflow forecasts, combined with related scheduling adjustments, contracts, and market opportunities, are reflected in a utilities’ revenue. One of the goals of the HydroWIRES Initiative is to quantify the flexibility of hydropower operations and understand its adaptability to changes in water supply, regulation, markets, and power grid needs. In partnership with North Carolina State University and the National Corporation of Atmospheric Research, researchers from PNNL and INL will use inflow forecasts, reservoir and power system models, and case studies to demonstrate the contribution of flow forecast to provide hydropower services to the grid. Flow forecast accuracy metrics, combined with regional power system analytics (including regional economics and generation portfolios), will help detangle the value of incremental improvement in flow forecasts. This research supports DOE in developing strategic partnerships with other institutions to invest in information products and decision-support practices for meeting power grid needs.

Water Risk for the Bulk Power System: Asset to Grid Impacts
Lead Companies
Sandia National Laboratories
Lead Researcher (s)
- Vince Tidwell
The majority of electricity generation in the United States (U.S.) is based on thermal and hydro power assets (90%, combined). The economic operations of hydropower assets, and the power grid, are affected by water availability, ambient temperatures, climate extremes (flood and drought), and water regulations, all of which have region-specific characteristics. A lack of water and/or warm temperatures can lower the available capacity at thermal and hydro assets and pose risks to the reliable operation of regional power systems. Future conditions are expected to significantly change and “accelerate” the hydrologic cycle, affecting both the timing of water availability and the temperature, exacerbating various risks to the power sector. Yet, there is no standardized, consistent mechanism for utilities and other stakeholders to understand how evolving predictive climate and hydrologic science can be translated to evaluate various potential water-related risks of their current grid assets (thermal, hydro) and future investment decisions.

Web-Based Decision Support System for the Upper Colorado River Basins

In an effort to improve the coordination and transparency of water management operations within the Upper Colorado River basin, Eastern Colorado Area Office (ECAO) is proposing to develop a Web-Based Decision Support System (DSS). The DSS would enable real-time sharing of a visual representation of the Upper Colorado River as it responds to actual and anticipated reservoir releases, diversions and return flows. The proposed DSS would provide a tool for immediately assessing and visually displaying the aggregate effects of operational changes at key locations within the basin.

White Paper Series on the Role of Hydropower in Changing Electricity Markets

- Audun Botterud, abotterud@anl.gov
The main objective for this project is to develop a series of forward-looking and technically rigorous white papers intended to motivate discussion of hydropower capabilities across the broader power system community. The project team will develop three white papers, focusing on topics such as evolving trends within electricity markets, contractual arrangements for hydropower, future grid requirements for a changing resource mix and how hydropower can contribute to meet these needs. Each white paper will contribute to the HydroWIRES goal of increased awareness and buy-in from the energy community for hydropower and pumped storage hydro to be part of the conversation about flexible, renewable electricity resources and a cleaner power grid. Overall, the project will lead to an increased understanding of hydropower’s role in evolving power systems and electricity markets. Technology Application
