FAQs
What is the purpose of an off‑river pumped storage plant?
It stores excess electricity by pumping water to an upper reservoir and generates power by releasing it during peak demand, providing grid balancing without affecting natural river flow.
How does the Purulia project differ from on‑river pumped storage?
Purulia’s off‑river design allows placement away from major waterways, reducing ecological disruption and offering greater site flexibility.
What capacity does the Purulia pumped storage add to the grid?
The exact megawatt figure is disclosed in operational reports, but it represents a substantial contribution to regional renewable capacity.
Why is pumped storage important for renewable energy integration?
It provides fast‑response, large‑scale storage that can absorb intermittent solar and wind generation, ensuring reliable supply.
Can other regions replicate the Purulia model?
Yes, the success of Purulia demonstrates that off‑river pumped storage can be replicated where suitable topography and water resources exist.
