Cabinet Approves 92 GWh Energy Storage Scheme
Why in News?
- The Union Cabinet approved a 92 gigawatt-hour energy storage scheme to strengthen India's clean energy programme, News On AIR reported on 4 November 2026.
- The scheme covers 30 GWh of battery storage, 60 GWh of pumped storage and 2 GWh of emerging energy storage technologies.
- It is to be implemented with State governments to ensure equitable distribution of storage capacity across the country.
- Union Minister Ashwini Vaishnaw, who briefed the media, said about 52 per cent of India's power generation capacity now comes from non-fossil sources.
- The report does not give the scheme's cost, support per unit or implementation period.
Key Terminologies
- Energy Storage
- Technology that stores electricity or its energy for use later. It helps supply power when solar and wind are not producing.
- Battery Storage
- Systems that store electricity in rechargeable batteries. The scheme covers 30 GWh of them.
- Pumped Storage
- A hydro system that pumps water uphill when power is cheap or surplus and releases it through turbines when power is needed. The scheme covers 60 GWh.
- Gigawatt-Hour
- A unit of stored energy equal to one billion watt-hours. A 92 GWh scheme can supply 92 gigawatts for one hour.
- Viability Gap Funding
- Government grant that bridges the gap between a project's cost and revenue so it becomes viable. A 2023 scheme used it for battery storage.
Key Issues
- Intermittency: Solar and wind produce power only at some times, so storage is needed to supply the grid in the evening or at low wind. The scheme adds 92 GWh of storage, in a split of 30 GWh battery, 60 GWh pumped and 2 GWh emerging technologies.
- Technology Mix: Pumped storage forms about two thirds of the capacity, and it needs suitable hill sites and years to build. Battery storage is faster to install but costly.
- Cost and Support: The report does not give cost or support per unit. In 2023 the Cabinet approved a Viability Gap Funding scheme for 4,000 MWh of battery storage by 2030-31 with an initial outlay of about Rs 9,400 crore, which shows the funding scale earlier.
- State Role: The scheme is to be implemented with State governments for equitable distribution. Sites, land and power purchase arrangements are State matters.
- Non-Fossil Share: Vaishnaw said about 52 per cent of capacity is non-fossil, and Union Minister Pralhad Joshi said on 2 November that capacity had crossed 310 GW. Capacity does not equal generation, so storage helps turn capacity into supply.
Key Implications
Positive/Pros/Merits
- Grid Stability: Storage lets the grid use more solar and wind and reduces waste of surplus power.
- Large Scale: 92 GWh is more than twenty times the 4 GWh planned under the 2023 scheme.
- Balanced Technologies: Including pumped storage, battery storage and emerging technologies spreads risk across options.
- Regional Spread: Working with States aims to place storage where it is needed across the country.
Negative/Cons/Demerits
- Missing Details: Without cost, support rate or timeline in the report, the pace and financing are unknown.
- Long Lead Times: Pumped storage projects take years to build and can face land, forest and environmental clearances.
- Battery Dependence: Large battery deployment needs imported components or domestic manufacturing, which is still developing.
- State Coordination: Delays by States in approvals or power purchase agreements can slow projects.
Key Initiatives
- Energy Storage Scheme, 4 November 2026: The Cabinet approved 92 GWh of storage, split into 30 GWh battery, 60 GWh pumped and 2 GWh emerging technologies, with State governments.
- Viability Gap Funding for Battery Storage, 2023: The Cabinet approved support of up to 40 per cent of capital cost for 4,000 MWh by 2030-31, with an initial outlay of about Rs 9,400 crore including Rs 3,760 crore of budgetary support, and at least 85 per cent of capacity to be made available to distribution companies.
- Bharat Renewable Energy Summit, 2 November 2026: The Ministry of New and Renewable Energy hosted it, and the target for non-fossil capacity is 500 GW.
- Electric Mobility: Union Minister Nitin Gadkari said on 4 November 2026 that electric vehicles reduce dependence on imported petroleum.
The Government says the storage scheme will strengthen India's clean energy programme and be carried out with State governments. Union Minister Ashwini Vaishnaw says about 52 per cent of power generation capacity is non-fossil. The funding details and period have not been published in the report.
Director's Perspective
Way Forward
- Publish the cost, support rate and timeline of the storage scheme, with State-wise capacity targets.
- Fast-track clearances for pumped storage sites through single-window approvals.
- Link storage tenders to domestic manufacturing of batteries to build local supply chains.
- Require storage plants to report availability and use, so benefits to the grid can be measured.
- Pair each new solar or wind project with transmission and storage planning.
The scheme addresses the main weakness of renewable power, which is timing. At 92 GWh, with a balanced mix of pumped, battery and emerging technologies, it matches India's growing solar and wind capacity. Yet the report gives no cost, no support rate and no timeline, and pumped storage takes years to build. In a Mains answer, credit the focus on grid stability and the State partnership, then conclude that success depends on clear financing, fast clearances and domestic manufacturing.

Frequently Asked Questions
What is the 92 GWh energy storage scheme?
The scheme approved by the Union Cabinet on 4 November 2026 covers 92 gigawatt-hours of energy storage: 30 GWh of battery storage, 60 GWh of pumped storage and 2 GWh of emerging technologies, to be implemented with State governments, News On AIR reported.
What is pumped storage?
Pumped storage is a hydro system that pumps water uphill when power is surplus and releases it through turbines when power is needed. It forms 60 GWh of the 92 GWh scheme approved by the Cabinet on 4 November 2026, according to News On AIR.
How much of India's capacity is non-fossil?
Union Minister Ashwini Vaishnaw said on 4 November 2026 that about 52 per cent of India's power generation capacity comes from non-fossil sources. Union Minister Pralhad Joshi said on 2 November that non-fossil installed capacity had crossed 310 GW.
