Paul Denholm is a member of the Transmission Group in the Grid Planning and Analysis Center and also a senior research fellow—the highest technical position at NREL—leading research in grid applications for energy storage and solar energy. He pioneered a variety of research methods for understanding the technical, economic, and environmental benefits and impacts of the large scale deployment of renewable electricity generation. He has delivered over 100 invited presentations to agencies including the National Science Foundation, the World Bank, and the International Energy Agency. He has co-authored over 100 articles related to renewable energy integration. While his official title is principal analyst, he is still an engineer at heart and in his free time he likes to build contraptions of dubious functionality, like a concentrating solar marshmallow cooker.
