This panel will provide different perspectives from each utility as they identify and address challenges and solutions. The focus of the discussion will be primarily distribution system interconnections, however, transmission issues may be addressed. A new activity inside utilities is joint transmission and distribution planning due to the potential of exported energy from the T/D substation. Utilities can no longer treat distribution substations as simply a load in their transmission planning process. The included speakers have direct experience with DER integration in their respective utilities, and will share their experience, including challenges and solutions. This discussion will benefit utilities, vendors, engineers/consultants, researchers, developers and others who is directly involved.
