This report is a continuation of the Storage Futures Study and explores the factors driving the transition from recent storage deployments with four or fewer hours to deployments of storage with greater than four hours. The report specifically builds on the first publication in the Storage Futures Study series, The Four Phases of Storage Deployment: A Framework for the Expanding Role of Storage in the U.S. Power System, that established a conceptual framework of roles and opportunities for new, cost-competitive stationary energy storage over the course of four phases of current and potential future storage deployment. This latest publication delves into Phases 2 and 3 when solar photovoltaics and storage increase the value of each other, and lower costs and technology improvements enable storage to be cost-competitive while serving longer-duration applications.
