There has been a rapidly growing level of interest in distribution planning and how to integrated distributed energy resources (DERs). The growth of DERs is fundamentally changing the nature of transmission and distribution system forecasting, planning, and operations. However, the current state of transmission and distribution planning and of DER integration into planning vary widely from utility to utility. For this project, our team conducted an inventory of current utility distribution planning practices and capabilities in Washington. The results were presented at Workshop on November 20th to a broad range of stakeholders.
