DER

Also called: Distributed Energy Resource A Distributed Energy Resource, or DER, is an energy asset connected within the distribution system rather than a large central generating plant. Depending on the context, DER can include solar PV, battery storage, controllable loads and bidirectional EV charging. DERs can change site import, export or both. Coordinating them matters on sites where chargers, BESS and generation share the same electrical connection. OCPP 2.1 introduced DER-control functions for charging-station integrations, reflecting the growing role of EV charging within wider site energy systems.
