India Approves Rs 14,500 Crore Plan for 92 GWh of Energy Storage

A five year push to store clean electricity

India's Union Cabinet approved Rs 14,500 crore in financial support on November 4, 2026, to develop 92 gigawatt hours of electricity storage, combining batteries, pumped water and emerging technologies. The programme is intended to help the country use more renewable electricity and supply power when solar and wind generation falls.

The Cabinet, chaired by Prime Minister Narendra Modi, approved support running from the financial year 2026-27 through 2030-31. The projects are expected to attract total investment of Rs 97,600 crore, according to the Prime Minister's Office's Cabinet approval statement.

The capacity will be divided into 60 GWh of hydro pumped storage, 30 GWh of battery energy storage and 2 GWh using alternative storage technologies. These are projects still to be commissioned. The announcement sets out a funding programme for building storage, with the electricity services arriving as projects enter operation.

Information and Broadcasting Minister Ashwini Vaishnaw outlined the decision at a briefing in New Delhi. He said implementation would involve state governments, with the aim of spreading storage capacity across the country.

The decision addresses a practical challenge in India's electricity transition: producing clean power and having it available at the right time require different kinds of infrastructure. Solar panels generate during daylight, while homes, businesses and factories also need electricity after sunset. Storage allows some electricity generated earlier to be used later.

How much electricity can 92 GWh hold?

A gigawatt hour measures an amount of energy. One GWh is one million kilowatt hours, the same basic unit commonly used to measure household electricity consumption. The planned 92 GWh therefore represents 92 million kilowatt hours of storage capacity.

Gigawatts and gigawatt hours answer different questions. Gigawatts measure how quickly a system can supply electricity; gigawatt hours measure how much energy it can hold. A storage facility's delivery rate determines how long its stored energy lasts.

The Cabinet statement gives the programme's energy capacity but leaves the combined discharge power, individual project locations, storage durations and commissioning dates unspecified. Those details will determine how much electricity the facilities can supply at once and which parts of the grid they serve.

The government says the 92 GWh addition is equivalent to 170% of India's current grid scale storage capacity. In simple terms, the planned addition is 1.7 times the existing base. The programme is therefore a substantial expansion relative to the storage infrastructure already available.

Pumped water gets the largest allocation

Pumped storage accounts for 60 GWh, or about 65% of the programme's capacity. Batteries account for about 33%, with the remaining roughly 2% reserved for emerging technologies. The allocation makes water storage the largest component of the plan.

Vaishnaw explained that pumped storage can use solar electricity to move water uphill. When electricity is needed, the water flows back down through turbines to generate power. The water held at a higher elevation acts as a store of energy.

Battery energy storage systems, known as BESS, store electricity for later release through a different process. Both approaches can help move electricity from a period of plentiful generation to a period when demand is higher or renewable output is lower.

The 2 GWh allocation leaves room for alternatives beyond the two main technologies. The official statement describes this category as emerging or alternative energy storage and does not identify the technologies that will receive support.

What the Rs 14,500 crore will pay for

The programme uses viability gap funding, usually shortened to VGF. This is public financial support intended to help make projects commercially workable when the income they are expected to earn is insufficient to attract investment on its own.

The government's Rs 14,500 crore commitment sits within an estimated Rs 97,600 crore of total project investment. Expressed in billions of rupees, those figures are Rs 145 billion and Rs 976 billion respectively. The public support amounts to about 14.9% of the estimated investment across the programme.

That comparison shows the intended financing model: government funding is meant to help bring forward a much larger pool of investment. Developers and other financing sources would provide the remaining funding needed to build the projects.

The approval gives a programme budget rather than a uniform subsidy rate for every facility. Project costs, technology choices and the eventual funding terms will shape how the assistance works in practice.

The government says this financial support should speed up construction of storage infrastructure, improve renewable electricity use and reduce reliance on conventional generation to balance supply throughout the day. Reliable and affordable electricity is the stated objective.

Who can take part, and how projects will be chosen

Public and private electricity distribution companies will be eligible for VGF support for battery and hydro pumped storage projects. Distribution companies are the businesses responsible for delivering electricity to customers through local networks.

Public and private entities will also be able to implement projects using alternative storage technologies. The programme therefore provides a role for both government owned and private organisations across its technology categories.

Storage capacity will be allocated through competitive bidding based on tariffs. In plain language, participants will compete on the price charged for the specified storage service, under the terms of the bidding process.

Tariffs matter because distribution companies must pay for the electricity and services they procure. The price of storing power will affect how useful a project is to a utility trying to meet demand reliably while managing costs.

State governments will be involved in implementation, Vaishnaw said. That gives the programme both a national financing framework and a role for states in expanding the storage infrastructure connected to their electricity systems.

Why transmission lines are part of the calculation

Vaishnaw used a solar plant with 10 megawatts of electricity evacuation capacity to explain another benefit of storage. Evacuation capacity means the ability of a connection to carry electricity away from a generating plant and into the wider network.

A connection serving solar generation may carry little solar electricity at night. Storage can shift some daytime generation into later hours, making it possible to use the connection across more of the day.

Vaishnaw, the minister presenting the Cabinet decision, described the opportunity to make greater use of existing infrastructure:

Due to storage, our existing transmission capacity, we can increase it multiple times,

His example concerned how much electricity a line can carry over time. A connection rated at 10 MW has that physical power limit, while storage can increase the number of hours during which it carries electricity. Better use of those hours can help stretch the value of investment in transmission infrastructure.

The programme also sits alongside plans to strengthen transmission capacity as renewable generation expands. Storage and transmission address related needs: one shifts electricity through time, while the other moves it between places.

A 40% domestic content rule for batteries

Battery projects supported by the scheme must meet a minimum domestic content requirement of 40%. The Cabinet statement presents this condition as a way to encourage manufacturing in India and reduce dependence on imported components.

The policy works through demand for equipment. Financial support helps projects proceed, while the domestic content rule directs part of their equipment demand toward Indian production. The government expects this to complement existing incentives supporting battery manufacturing.

Indian manufacturers could gain customers as storage developers procure equipment for the 30 GWh battery allocation. The commercial opportunity will depend on the projects awarded, their procurement requirements and the ability of domestic suppliers to provide the necessary products.

The Cabinet also approved a separate Rs 2,814 crore capital expenditure support scheme for lithium and nickel processing. Those materials are used in battery manufacturing, making mineral processing relevant to the wider effort to build domestic industrial capacity.

At the briefing, Vaishnaw also described support for processing 24 identified critical minerals, covering material obtained through mining and recycling. Critical minerals are raw materials needed by industries such as batteries, electronics and defence manufacturing. The broader processing push aligns with the National Critical Minerals Mission.

Storage development and mineral processing address different parts of the production chain. Storage projects create demand for finished systems; processing prepares raw materials for industrial use. The government is seeking to develop both electricity infrastructure and the manufacturing capacity that supplies it.

How the plan fits the 2031-32 requirement

India is expected to require 411 GWh of grid scale energy storage by 2031-32, according to the Cabinet statement. The new programme's 92 GWh represents about 22.4% of that requirement, calculated by dividing 92 by 411.

The comparison places the approval in perspective: it provides a large contribution toward the stated requirement, alongside the storage capacity India already has and other capacity that will be needed.

Vaishnaw said non-fossil sources account for nearly 52% of India's installed electricity generation capacity. Installed capacity measures the rated output of generating equipment. The amount of electricity actually generated depends on how much that equipment operates, including the availability of sunlight and wind.

Storage helps connect those two parts of the electricity system. When renewable generation is plentiful, some energy can be saved. When output falls or demand rises, stored energy can return to the grid. Consumers would experience the benefit through a steadier supply rather than through the storage facilities themselves.

The funding period and the later storage requirement create the programme's main timetable:

• November 4, 2026: The Union Cabinet approved Rs 14,500 crore in VGF support for 92 GWh of storage.
• Financial years 2026-27 to 2030-31: The approved support programme is scheduled to operate.
• Financial year 2031-32: The government identifies a requirement for 411 GWh of grid scale storage.

The immediate work is to turn the approval into competitively allocated projects, financing arrangements and construction. Their eventual operation will determine how much stored electricity becomes available to help utilities meet demand.
