Presently the operating storage capacity in India is 4.74 GW in PHS (working in storage mode is 3.3 GW) and 20 MW in BES. Around 40 MW of BSS under procurement and 2.7 GW of PHS under construction. The target of 27 GW is far away from the reality. One of the reasons is high cost of BSS and long gestation period of PHS.

Pumped Storage Hydropower. High efficiency in energy storage and release, especially during peak electricity demand. Higher capital cost due to construction of reservoirs and dams, but cost-effective in long-term energy management. Potential impact on ecosystems and water flow, but generally lower than fossil fuels.
2 · None of the previous research endeavors considered the integration of small-scale pumped hydro storage (PHS) systems, specifically a PHS 245 KWh, into their hybrid energy generation setups. This gap in knowledge highlights the untapped potential of PHS in enhancing energy storage and grid stability for off-grid communities.
