UPSC Prelims 2024 Question on –Distributed Energy Resources(DES) Examples
Q. Consider the following:
1. Battery storage
2. Biomass generators
3. Fuel cells
4. Rooftop solar photovoltaic units
How many of the above are considered “Distributed Energy Resources”?
✅ Correct Answer: (d) All four
Explanation:
Distributed Energy Resources (DERs) are small-scale, modular electricity generation and storage systems located close to the point of consumption, usually producing less than 10 MW.
Examples of DERs include:
✅ Rooftop solar photovoltaic units
✅ Battery storage systems
✅ Biomass generators
✅ Fuel cells
Wind turbines, mini-hydel plants
Combined heat and power (CHP) units
Electric vehicle batteries exporting power to grid
Therefore, all four given options qualify as Distributed Energy Resources.
