In order for Vermont to meet its ambitious goal of 90% renewable energy penetration by 2050, an optimal and replicable approach to distributed energy resources (DERs) integration needs to be
developed at the distribution level. Significant changes in the state’s power distribution-system architecture and operations are needed to mitigate the impacts of high penetrations of variable DERs
including solar, wind, and energy storage. Key insights from what we learn in Vermont can be applied to the rest of the nation.
