Dr. Brady Stoll is a member of the Grid Systems Analysis Group in the Strategic Energy Analysis Center.

Dr. Stoll is passionate about building new analytical tools for exploring future power systems and ways to improve renewable integration in the United States and abroad. After working at NREL as an intern on the Eastern Renewable Generation Integration Study, she joined the laboratory full-time as a postdoc and is now a lead engineer for a variety of projects.

Dr. Stoll’s primary tools are the Resource Planning Model, a tool that analyzes future challenges for the electric grid—including policy impacts and falling renewable energy cost—and production cost models, which she uses to analyze the potential impacts of demand response and other flexible technologies on operations of the electric grid. Her favorite programming languages are python for tool development, and R for visualizations.

Dr. Stoll models the transmission-level electricity grid and the impacts of new technologies on the total cost of operating the grid, as well as the operational changes resulting from these new technologies. She has specifically analyzed the benefits of expanded combined heat and power technologies, the potential for CSP, and the value of demand response and storage, ranging from manufacturing facilities to the electric grid.
