All inland bodies of water have some level of greenhouse gas (GHG) emissions resulting from microbes in the environment that naturally produce carbon dioxide and methane. Current estimates of GHG emissions from reservoirs are incomplete and vary widely, which makes it challenging to calculate total emissions related to hydropower operations. To better quantify and reduce reservoir emissions related to hydropower, researchers at Oak Ridge National Laboratory are using advanced tools to measure reservoir GHG emissions released through multiple processes, including degassing as water is passed through turbines. Warmer water temperatures in the future are expected to alter GHG emissions from reservoirs, but better understanding the current GHG emissions can improve models that inform reservoir management to mitigate emissions for climate resilience.

Modernizing the U.S. electric grid means integrating new technologies that are typically connected to the internet. This growing network of integrated systems and technologies—often called the Internet of Things—increases opportunities for security compromises, making cybersecurity a key focus for energy infrastructure, particularly hydropower facilities. 

A new tool developed by the National Renewable Energy Laboratory (NREL) aims to provide tailored cybersecurity for hydropower plants. The Cybersecurity Situational Awareness Tool for Hydropower (CYSAT-Hydro) is a data-driven, hardware-agnostic cybersecurity tool designed to protect facilities from becoming access points for hackers and malicious actors. The tool uses artificial intelligence to detect anomalies in technology networks, then sends detailed information about cyberattacks to hydropower operators in real time to help restore functionality post-cyberattack.

The U.S. Department of Energy launched an incentives program for infrastructure improvements at hydropower facilities. The program, Maintaining and Enhancing Hydroelectricity Incentives—also referred to as Section 247 of the Energy Policy Act of 2005—was funded through the Bipartisan Infrastructure Law. It made over $550 million dollars available in 2024 to eligible hydropower facilities to invest in infrastructure enhancements that increase grid resilience (including the addition of energy storage capacity), advance dam safety, or support environmental improvements. Through this incentive program, 293 hydropower facilities across 33 states received funding to improve their facilities. The effort directly supports the safety, security, and functionality of hydropower facilities throughout their lifetime, including modernizations necessary for hydropower to continue providing valuable services.
