Background
Solar and wind generation vary with weather and time, whereas electricity supply and demand must remain balanced in real time. Energy storage absorbs electricity, stores it in another form and returns it when required, subject to conversion losses. Pumped storage uses water held at different elevations, while batteries store energy electrochemically. Viability-gap funding is public financial support intended to make socially or economically desirable infrastructure commercially viable. In electricity, storage complements transmission, flexible generation and demand management rather than replacing them.
What the Cabinet has approved
The scheme covers fresh, yet-to-be-commissioned grid-scale storage capacity during 2026-27 to 2030-31. Its planned technology mix comprises 60 GWh of hydro pumped storage, 30 GWh of battery energy storage systems and 2 GWh through alternative technologies, with total estimated investment of ₹97,600 crore.
Capacity will be allocated through tariff-based competitive bidding. Both public and private sector electricity distribution companies are eligible for VGF support for battery and pumped-storage projects; alternative-technology projects will also be implemented by public and private sector entities.
The government states that the additional capacity is equivalent to 170% of present-day grid-scale storage capacity and will help meet a requirement of 411 GWh by 2031-32. This is a contribution towards the projected requirement, not a claim that the scheme alone will fulfil it.
- BESS projects must meet a minimum domestic content requirement of 40%.
- The supplied announcement does not specify a uniform project-level subsidy rate, disbursement schedule or detailed domestic-content accounting method.
- The ₹97,600-crore figure is estimated total investment, not the approved government funding outlay.

Why viability-gap funding matters—and where it falls short
Storage can create system-wide benefits through peak supply, renewable integration and grid support, but a project's contracted revenues may not capture all these benefits. High initial investment, uncertain utilisation and unclear remuneration for different services can therefore restrict financing.
VGF can reduce the funding gap and improve project bankability. Competitive bidding can help translate public support into lower tariffs, provided contracts specify comparable performance obligations and realistically allocate construction, operating and payment risks.
However, financial assistance cannot by itself correct weak payment security, poor site selection or unremunerative operating arrangements. Storage economics also depend on charging-power costs, conversion losses, battery replacement requirements and the availability of dependable buyers.
- Public support should enable additional, useful capacity rather than subsidise projects that would proceed without assistance.
- Low bid tariffs must be assessed alongside deliverability, service quality and lifecycle costs.
- Clear rules for earning revenue from multiple compatible grid services can strengthen viability without indefinite subsidy.
Pumped storage and batteries are complementary
Pumped-storage plants use electricity to move water to an upper reservoir and generate electricity when water flows back through turbines. They can support bulk energy shifting and long asset lives, but feasibility depends on topography, water arrangements, civil works and environmental and social safeguards.
Battery systems can respond rapidly and can be located closer to substations, renewable projects or demand centres. Their usefulness for balancing and peak support must be weighed against degradation, thermal safety, replacement costs and end-of-life management.
Technology choice should follow the service required, location and lifecycle cost rather than a universal preference. The alternative-technology allocation creates room for other storage approaches, although the supplied announcement does not identify the eligible technologies.
- GWh measures the quantity of energy stored; GW measures the rate at which power can be delivered.
- Storage duration depends on both energy capacity and discharge power, so a GWh target alone does not establish hours of supply.
- Environmental impacts of pumped storage depend on project design, including whether existing reservoirs or new impoundments are used.
Renewable integration requires more than storage capacity
CREA data cited in the pre-decision report recorded about 1,835 million units of renewable-energy curtailment during July and August 2026, comprising 1,462 million units of solar and 373 million units of wind electricity. These figures highlight an integration challenge but do not establish that all the curtailed electricity could have been recovered through storage.
Storage can absorb surplus generation and discharge during evening peaks or other periods of scarcity. Yet its effectiveness depends on location, charging opportunities, transmission access and dispatch coordination. A storage asset cannot resolve every network bottleneck merely by adding energy capacity.
Electricity-market and regulatory arrangements must therefore recognise storage's charging and discharging functions and compensate the services it actually supplies. Better forecasting, transmission reinforcement and demand response remain essential complements.
- Measure success through reliable delivery, availability and useful renewable-energy absorption, not installed capacity alone.
- Storage shifts energy across time; it is not a primary energy source.
- Its emissions benefit depends partly on the electricity used for charging and the generation displaced during discharge.
Domestic manufacturing: demand certainty with implementation risks
The minimum 40% domestic content requirement for BESS seeks to connect storage deployment with domestic manufacturing. The source also reports an existing production-linked incentive scheme for 50 GWh of advanced chemistry cell manufacturing capacity, of which 10 GWh would account for grid-scale stationary storage.
Demand-side procurement support and supply-side manufacturing incentives can reinforce each other. However, domestic content does not automatically establish domestic cell production, mineral security or technological capability; outcomes depend on which components and value addition qualify.
A separate proposal for capital expenditure support for critical-mineral processing was reported as coming before the Cabinet. The supplied material does not confirm its approval, and its reported possible support rate must not be treated as a provision of the storage VGF scheme.
- Transparent domestic-content verification can limit token localisation and misreporting.
- Procurement should balance domestic capability-building with quality, safety, cost and timely delivery.
- Battery recycling and responsible mineral sourcing should accompany manufacturing expansion.

Frequently asked questions
What does the energy storage VGF scheme support?
It supports 92 GWh of fresh, yet-to-be-commissioned storage: 60 GWh of pumped hydro, 30 GWh of batteries and 2 GWh of alternative technologies. The approved VGF outlay is ₹14,500 crore for 2026-27 to 2030-31.
Will VGF alone make storage projects financially viable?
Not necessarily. Projects also need credible revenues, payment security, appropriate charging-power arrangements and realistic provision for construction, operating and replacement costs.
Can storage eliminate renewable-energy curtailment?
Storage can reduce curtailment when it can absorb surplus electricity and discharge usefully later. Network constraints, unsuitable locations and operational limitations mean that it cannot eliminate every instance of curtailment.
Does the announcement specify a uniform subsidy percentage for storage projects?
The supplied announcement does not specify one. The possible support rate reported for a separate critical-mineral processing proposal should not be applied to the storage scheme.
