Degree of self-sufficiency

The degree of self-sufficiency describes the share of the load consumption that is supplied by the PV battery system. The degree of self-sufficiency is defined by the ratio between the PV energy which is used directly plus the energy discharged from the battery and the load demand.

Demand Response

Reduction of retail electricity end-users’ electric load in response to control or price signals. DR resources are deployed and used in lieu of installing/operating peaking generation capacity.

Demand Side Management

Measures or programs undertaken by a utility designed to influence the level or timing of customer demands for energy in order to optimize the use of available supply resources, in turn allowing suppliers to defer the purchase of additional generating capacity. The term is used for all activities or programs undertaken by Load-Serving Entity or its customers to influence the amount or timing of electricity they use.

Distributed Energy Resource

Small power sources, deployed at the sub-transmission or distribution level, that can be aggregated to provide power necessary to meet regular demand. As the electricity grid continues to modernize, DER such as storage and advanced renewable technologies can help facilitate the transition to a smarter grid.
