For each of the past seven years, EPRI’s research program on Integrated Energy System Planning and Market Analysis (Project Set 178B) in conjunction with member electric companies has developed different scenarios of potential future technology, regulatory, and market conditions that may exist in the United States in the coming decades, and then analyzed how the United States electric sector might evolve under these scenarios. This report, and the accompanying slide presentation and Excel spreadsheet dataset, highlights the analysis conducted and results from our 2019 REGEN Scenarios Analysis Project. In 2019, we analyzed how the U.S. electric power generation mix may evolve from 2015 to 2050 under 14 different scenarios. These scenarios explored the potential impacts of key uncertainties, including:
(i) future natural gas prices; (ii) approaches to achieving zero electric sector carbon dioxide (CO2) emissions; (iii) evolution of hydrogen (H2) infrastructure; and, (iv) the potential role of energy storage systems.
