How are DERs used?
DER systems can be used in several ways. They can help municipalities and other energy users manage energy bills and ensure reliable power by augmenting existing energy services. DER systems also enable a facility to operate independently of the electric power grid, whether by choice or out of necessity. Certain DER systems can even lower emissions and improve fuel utilization on site.
Utilities can use DER technologies to delay, reduce, or even eliminate the need to obtain additional power generation, transmission, and distribution equipment and infrastructure. At the same time, DER systems can provide voltage support and enhance local reliability.
