Cabinet clears a ₹14,500 crore viability gap scheme to build 92 GWh of grid-scale energy storage

India now adds large amounts of solar power every year, which leaves its grid with a timing problem. Generation peaks at midday, but demand peaks after sunset. On 4 November 2026 the Union Cabinet approved a major support package: a ₹14,500 crore Viability Gap Funding (VGF) scheme to help build 92 GWh of grid-scale energy storage.

Information and Broadcasting Minister Ashwini Vaishnaw announced the decision at the post-Cabinet briefing. He said the scheme would be implemented together with state governments. The projects it supports are expected to draw a total investment of about ₹97,600 crore, so each rupee of central support is meant to bring in more than six rupees of project capital.

What the scheme funds

Reports of the approval give the following details:

• Duration: five years, FY2026-27 to FY2030-31.
• Capacity mix: 60 GWh of pumped storage projects (PSP), 30 GWh of battery energy storage systems (BESS) and 2 GWh from emerging storage technologies.
• Who can apply: public and private electricity distribution companies (discoms) can receive VGF for battery and pumped-hydro projects. Public and private entities can implement the emerging-technology projects.
• Local content: battery projects must meet a minimum 40% domestic content requirement.
• Why now: the government puts India's grid-scale storage requirement at about 411 GWh by 2031-32. This scheme is meant to fund a large share of that build-out.

VGF is a grant that closes the gap between what a project costs and what the market will pay for its output. It does not cover the whole project. For storage, the gap is mostly upfront capital. Batteries and pumped-hydro plants earn money by shifting energy across the day, and without support many projects would not meet lenders' return thresholds.

Why the split favours pumped hydro

The scheme puts twice as much capacity into pumped hydro as into batteries, which reflects how the two technologies work. Pumped storage moves water between an upper and a lower reservoir. Its power and energy capacity can be sized separately, so the cost of each extra hour of storage falls quickly. That makes it well suited to long, multi-hour shifting. Its drawbacks are well known: high upfront cost, construction times that can run to a decade, and strict siting needs. India already has pumped-storage plants such as Tehri in Uttarakhand.

Lithium-ion batteries scale in modules, can be built in months and can be configured for different storage durations. They also have higher round-trip efficiency. The 30 GWh battery tranche, combined with the 40% domestic-content rule, gives a direct demand signal to India's emerging cell and pack industry. Industry trackers have flagged that industry as strong in assembly but still short of cell-making capacity.

The 2 GWh for emerging technologies is small. It does leave room for options such as sodium-ion, flow batteries, thermal or gravity storage to show what they can do at grid scale. Several Indian start-ups and utilities are already piloting these.

How it builds on earlier schemes

The new framework supports batteries, pumped storage and alternative technologies together. The primary release specifies tariff-based competitive bidding; its 92 GWh is supported capacity yet to be commissioned, not installed capacity.

Why it matters for India's energy transition

Storage is one important constraint on integrating variable renewable generation, alongside transmission, market design and grid operations. Without it, discoms facing evening peaks have to fall back on coal or curtail daytime solar. The government presents the scheme as a way to integrate large amounts of renewable power, improve round-the-clock power availability and build up domestic battery manufacturing.

The scheme also connects to another decision taken the same day. Alongside it, the Cabinet approved a ₹2,814 crore scheme to support lithium and nickel processing plants, which targets the materials end of the battery supply chain. Read together, the two decisions aim to create demand for storage and, in parallel, the domestic supply of materials to meet it.

What it means for industry

For Indian manufacturers, the scheme gives some visibility on demand. A five-year pipeline of 30 GWh of battery projects with a domestic-content floor helps justify investment in module assembly, battery management systems, power conversion equipment and, eventually, cells. Pumped-storage projects will drive orders for turbines, civil works and grid connections, areas where Indian engineering firms already have experience. Developers of emerging technologies get a funded route to their first grid-connected demonstrations, which investors often require before backing larger plants.

Open questions

Discom finances will shape how well the scheme works, since distribution utilities are the main eligible applicants and many remain financially stretched. Other issues to watch:

• Bid design: whether states tender storage as standalone capacity or tie it to solar and wind.
• Pumped-hydro timelines: whether projects can be permitted and built within a five-year funding window.
• Domestic content: whether the 40% requirement can be met without raising battery costs while Indian cell factories are still ramping up.
• Grid operations: whether system operators can dispatch tens of gigawatt-hours of new storage efficiently, which will depend on market rules for ancillary services and time-of-day pricing.

Detailed implementation guidelines and tender documents will be needed to assess these points.
