This report presents the datasets and analytical tools that can be used to support cost-effective distributed energy resource (DER) planning, necessary for California to meet its clean energy goals. The study consisted of two key research tasks: a market assessment of firms able to analyze large volumes of data, and an evaluation of datasets relevant to DER analysis. The report presents findings related to 1) data, analytics, and information access; 2) economics and value, which focuses on how DERs are compensated for the related services; and 3) emerging trends, which include findings related to the impact of transportation electrification on the future grid needs and planning.
