As per international report, India ranked ninth in terms of pumped storage hydro power with 4.8 GW.
The top three countries in world are China (30.3 GW), Japan (27.6 GW) and United States (22.9 GW).
Energy storage in the form of pumped storage hydropower (PSH), the world’s ‘water battery’, is a proven technology that has continuously evolved to suit the needs of changing power systems. PSH currently accounts for over 94 per cent of installed global energy storage capacity, and over 96 per cent of energy stored in grid scale applications.
PSH provides flexibility through system inertia, frequency control, voltage regulation, storage and reserve power with rapid mode changes, and black-start capability.
As a result of a resurgence of interest in PSH around the world, it is estimated that global PSH capacity will grow by 78 GW by 2030, considerably more than other forms of energy storage technologies.
In 2019, only 304 MW of new pumped storage capacity was added.
