The Electric Power Research Institute (EPRI) engaged AWS Truepower (AWST) to provide simulated solar energy output data for the lower 48 states under the PRISM 2.0 Project. AWST obtained and processed historical modeled solar irradiance data over the 14-year period 1997–2010. The project team used the data to identify the best solar resource in each of the lower 48 states up to 1% of developable land area; generate solar power output time series for utility-scale sites for several technologies; determine the rooftop solar resource in cities across the lower 48 states; and to synthesize solar power output time series for rooftop systems.

Each of the delivered data sets underwent a detailed validation process to ensure the results were consistent with actual meteorological observations, and therefore representative of realistic power output profiles. This document presents AWST’s final technical report on the methods used, the results achieved, and the validation of the data sets.
