Brady Cowiestoll

Researcher IV-Model Engineering


Brady Cowiestoll is member of the Capacity Expansion & Electricity Markets Group in NREL's Grid Planning and Analysis Center. In her role as engineer and researcher, she predominantly studies future grid systems, how they evolve, how they operate, and understanding how flexible technologies may become more widely utilized under emerging grid conditions. She utilizes Python, GAMS, and R to create new tools to enable further analyses of capacity expansion and production cost models, and to help these models to interact to extend our ability to represent and understand the future challenges our grid may face.
