Decarbonization of the grid A collaboration between Princeton’s Andlinger Center for Energy and the Environment and NRG Energy, the largest competitive power producer in the United States, aims to better understand how to “decarbonize” the U.S. electrical power grid by transitioning the nation’s power supply from its reliance on high-carbon-emitting power sources to a greater use of renewable and low-carbon-emitting fuels. The collaboration builds on the shared interests of the Andlinger Center and NRG Energy to create a low-carbon future for the U.S. power sector. Andlinger’s Energy Systems Analysis Group, which includes Energy Systems Modeler Thomas Kreutz, Senior Research Engineer Eric Larson and Senior Research Scientist Robert Williams, will work with NRG analysts to build a model of the grid that will enable investigations of the prospective impacts of alternative new electricity pricing policies, carbon pricing policies, and advanced generation and storage technologies.
