A Distributed Energy Resource (DER) is the name given to renewable energy units or systems that are commonly located at houses or businesses to provide them with power. Another name for DER is “behind the meter” because the electricity is generated or managed ‘behind’ the electricity meter in the home or business. Common examples of DER include rooftop solar PV units, battery storage, thermal energy storage, electric vehicles and charges, smart meters, and home energy management technologies. Energizer Homepower is an example of a Distributed Energy Resource (DER).
