To properly understand and model the changing US electricity distribution grid, economists and other social scientists need in-depth training on the technological and engineering complexities of the electricity distribution system. This grant provides funding to the Colorado School of Mines (CSM) to organize and host a week-long summer school for early-career economists and other social scientists designed to provide such training. Each week-long summer school, to be held twice each summer over the course of two summers, would include tailored classroom training; engagement and lectures by senior utility, government, and nongovernmental experts; and an experiential component through tutorials held at NREL’s Energy Systems Integration Facility. Participating expert instructors include those in distribution systems planning (Doug Arent and Michael Coddington), grid integration (Barbara O’Neill), and power systems engineering (Benjamin Kroposki). Summer school participants—which include advanced graduate students, postdoctoral fellows, and junior faculty—will be broadly recruited from professional societies, such as the Association of Environmental and Resource Economics and the United States Association of Energy Economics, and from with universities that have doctoral programs with a strong focus in energy economics.
