UPSC IAS – 2024
Distributed Energy Resources (DERs) are small, modular energy generation, storage, or demand-response technologies located at or near the point of consumption. This distributed nature contrasts with traditional centralized power generation.
– Battery storage stores energy and can be used locally, fitting the definition of a DER.
– Biomass generators can be deployed at various scales, including small-scale, localized generation which qualifies as a DER.
– Fuel cells are capable of providing localized power generation and can be considered DERs.
– Rooftop solar photovoltaic (PV) units are a quintessential example of DER, generating power at the point of use.
DERs can improve grid reliability, resilience, and efficiency by reducing transmission losses and providing local support during peak demand or outages. They also play a crucial role in integrating renewable energy sources into the grid. Other examples of DERs include small wind turbines, combined heat and power (CHP) systems, and electric vehicles capable of vehicle-to-grid (V2G) power flow.
