The United States relies heavily on fresh surface water-dependent electricity generation, using water as fuel for hydropower and coolant for water dependent thermo-electric plants. Climate change and associated warmer temperatures and more frequent extreme events are expected to disrupt water availability as well as electricity demand. Decarbonization of the grid is also expected to change the generation portfolio and overall needs from water-dependent generators. Hydropower is part of both water and energy systems, making its operations exposed to climate from different directions. The representation of hydropower in power system models is key to evaluate not only the reliability of the future power grid but also to inform hydropower operators about associated future operating needs. To develop resilient water-dependent sectors amidst major changes in climate and society, we have developed new ways to integrate climate and power system studies. Come learn how PNNL scientists are advancing water-energy long term planning and how those advances impact regional strategies.
