SITE SUITABILITY ASSESSMENT FOR CLOSED-LOOP PUMPED STORAGE HYDROPOWER, KALVARAYAN HILLS, TAMIL NADU
The objective of this report is to identify potential off-river reservoirs suitable for a pumped storage hydropower (PSH) system in the Kalvarayan Hills . PSH is crucial in the evolving energy landscape , characterized by the increasing presence of variable and intermittent renewable energy sources like solar and wind. These renewables pose significant challenges to grid stability, making integrating storage and ancillary services imperative. Among various storage technologies, PSH stands out as a clean, domestically available, and internationally accepted solution that has proven effective over time. The global status of PSH highlights its importance , with substantial renewable capacity added in recent years. Countries like China, Japan, and the United States lead in PSH technology, facilitating the integration of fast-growing renewables into the grid. In India, the potential for PSH is notable, with several projects in various s...
