Renewable Energy Storage with Pumped Hydro
India is racing toward its 450 GW renewable target by 2030 — but storing all that clean power is the real challenge. Discover how Pumped Hydro Storage is emerging as India’s game-changer, balancing the grid, boosting sustainability, and powering the nation’s green future.
India has set an ambitious target of 450 GW renewable capacity by 2030. Also, India’s integrated power grid is one of the largest synchronous power grids in the world.
The high penetration of intermittent renewable sources such as wind and solar poses a major challenge to grid balancing, stability, and security.
Such challenges are associated with meeting the variation in generation demand while providing reliable services and have motivated the development of energy storage.
Further, the deployment of energy storage depends on the economic merits of storage technologies, and Pumped Hydro Storage is ideally suited to play a leading role.
The Ministry of Power (MoP), Government of India, has announced the promotion of RE and Pumped-Hydro Energy Storage (PHES) for decarbonizing the Indian grid.
PHES offers superior features such as continuous generation for 6-10 hours (depending on the storage capacity of its reservoir), high ramping capability (around 1% of its capacity/second), efficiency in the range of 70% to 80%, and long lifespan of 40 to 60 years.
Pumped Hydro Storage
They are large-scale energy storage plants that use gravitational force to generate electricity. It is a system of two interconnected reservoirs with one at a higher elevation than the other,…
