In June, EPRI and Stanford University Bits & Watts Initiative co-hosted a virtual workshop with support from VmWare that brought together utility and information technology companies to discuss the development of a data platform and enabling technologies to achieve the Digital Grid vision. This continuing interactive panel series provides an opportunity to take this vital conversation to the next step, examining the latest advances, emerging policies, and breakthrough research on customer DER integration every Wednesday during the summer quarter.
