India’s renewable vitality sector is poised for a significant funding surge, with projections exceeding $250 billion by 2030. Of this, photo voltaic photovoltaic (PV) tasks are anticipated to draw round $15.5 billion, whereas battery manufacturing may see inflows of ~$2.7 billion, underscoring the nation’s accelerating clear vitality transition.

To boost grid reliability and vitality storage capability, the federal government has launched a Rs. 5,400 crore Viability Hole Funding (VGF) scheme for the event of 30 GWh of Battery Power Storage Techniques (BESS). This initiative is projected to attract investments of almost Rs. 33,000 crore and play a crucial position in supporting large-scale renewable vitality integration.

In an additional enhance to renewable infrastructure, the Ministry of New and Renewable Power (MNRE) has proposed establishing 13,000 MW of renewable vitality capability coupled with a 12,000 MWh BESS challenge in Ladakh. On 18th October 2023, the Cupboard Committee on Financial Affairs (CCEA) accepted the development of an Inter-State Transmission System (ISTS) to allow environment friendly energy evacuation and nationwide grid integration, marking a major step towards harnessing Ladakh’s renewable vitality potential.
Following are just a few corporations with capex plans within the BESS ecosystem:
With a market cap of Rs. 96,905 crores, the inventory moved down by round 2 p.c on BSE to shut within the pink at Rs. 3,368.95 on Tuesday.

The corporate has achieved important milestones within the building and engineering phases of its Battery Power Storage giga-factory at Jamnagar, with 40 GWh of producing capability at present underneath speedy growth.
As soon as operational, the services in Jamnagar will allow the corporate to provide round the clock renewable energy, leveraging each in-house photo voltaic PV modules and battery vitality storage techniques.
The corporate is establishing a battery giga-factory, scheduled to be operational by 2026, to fabricate battery chemical compounds, cells, packs, and containerised vitality storage options, together with a battery recycling facility. The corporate goals to provide Lithium Iron Phosphate (LFP)-based batteries at globally aggressive lifecycle prices and is actively fast-tracking the commercialisation of sodium-ion battery expertise.
Additional, in 2023, the corporate dedicated Rs. 60,000 crore funding in direction of developing world-scale, built-in services to assist this ecosystem. These embrace a completely built-in photo voltaic photovoltaic manufacturing advanced, superior vitality storage techniques for cell and battery pack manufacturing, electrolyser manufacturing facility, energy electronics and semiconductor growth, primary and auxiliary materials manufacturing, and devoted R&D services for all New Power applied sciences.
With a market cap of Rs. 11,180 crores, the inventory moved down by round 1 p.c on BSE to shut within the pink at Rs. 579.35 on Tuesday. HEG Restricted acknowledged that its subsidiary, HEG Greentech, is at present establishing a 20,000-ton anode manufacturing plant, which is anticipated to grow to be operational by March 2027, with income era commencing thereafter.
HEG Restricted has outlined a complete capex plan of Rs. 1,800-1,900 crore for its 20,000-ton capability growth challenge.
