The Union Cabinet has greenlit a ₹14,500 crore Viability Gap Funding (VGF) support package to accelerate the adoption of utility-scale energy infrastructure across the country. Designed as a central energy storage scheme, the plan aims to create 92 Gigawatt-hour (GWh) of grid-scale energy storage capacity by the year 2031. This initiative seeks to integrate rapidly expanding solar and wind generation while maintaining overall grid frequency and stability.

Financial Structure of the Energy Storage Scheme
High upfront capital costs have long posed a hurdle for grid-scale storage deployment in the power sector. By providing direct financial assistance through Viability Gap Funding, the central government aims to lower capital expenses for utility operators and storage developers. The total VGF outlay of ₹14,500 crore will bridge financial gaps that previously made large-scale battery installations and pumped hydro assets economically challenging for state distribution companies.
This direct funding support forms part of a larger ₹97,600 crore investment programme planned for grid-scale energy storage nationwide. By absorbing a portion of the initial infrastructure costs, the government intends to bring down the levelized cost of energy storage. Lower storage costs allow power distribution utilities to purchase stored renewable power at competitive tariffs during evening peak demand periods.
The financial framework is designed to encourage competitive bidding among private and public power producers. Project developers receiving VGF allocations will be obligated to meet strict commissioning targets and grid performance standards. This structure helps de-risk private capital participation in large infrastructure developments across multiple states.
Addressing Renewable Intermittency and Grid Reliability
As India adds gigawatts of solar and wind energy to its national grid, managing generation fluctuations has become a operational priority. Solar energy production reaches its peak during midday hours when consumer demand is not always at its highest, whereas peak electricity consumption typically occurs in the evening. Without adequate storage, excess green energy risks being curtailed or wasted.
The implementation of this energy storage scheme will provide transmission networks with the flexible capacity needed to absorb excess daytime solar generation and release it during peak hours. Storage facilities act as a buffer against voltage fluctuations, sudden weather-related dips in renewable generation, and sudden load changes. This balancing capability reduces reliance on fossil-fuel backup generators for frequency regulation.
Grid operators will gain access to rapid-response energy reserves capable of deploying power within milliseconds. Enhanced storage capacity helps maintain regional grid equilibrium, preventing localized transmission congestion and protecting sensitive electrical assets from sudden supply shocks.
Support for BESS, Pumped Hydro, and Emerging Technologies
The policy framework covers a wide spectrum of technical solutions rather than committing to a single energy storage technology. A major share of the planned 92 GWh capacity will be allocated to Battery Energy Storage Systems (BESS). BESS installations offer fast response times, modular scalability, and rapid deployment schedules, making them suitable for substations and urban distribution nodes.
Pumped Storage Projects (PSP) also form a core element of the overall technology portfolio. Pumped hydro infrastructure offers long-duration storage capabilities by moving water between reservoirs at different elevations during off-peak hours. When power demand spikes, released water drives hydro turbines to generate electricity over extended hours.
By maintaining a technology-neutral stance within the energy storage scheme, the government allows developers to select optimal technologies based on regional geography, water resource availability, and land constraints. Advanced lithium-ion chemistries, flow batteries, and mechanical storage technologies will all have opportunities to bid under the scheme’s parameters.
Data-Driven Governance Through the VISTAR Initiative
Alongside direct infrastructure funding, the Cabinet decision incorporates the VISTAR initiative to strengthen sectoral planning. The VISTAR program will integrate artificial intelligence and machine learning algorithms into energy data management systems. These computational tools will analyze generation patterns, load profiles, and weather forecasting data to optimize storage deployment locations.
The VISTAR initiative will also expand the volume and frequency of energy sector surveys conducted by central authorities. By introducing new data streams and standardized reporting metrics, policymakers can identify transmission bottlenecks and monitor energy consumption trends in near real-time. This data-backed approach ensures that capital under the energy storage scheme is directed toward grid sectors experiencing the highest congestion.
Machine learning models will also assist power utilities in predicting localized electricity demand surges. Enhanced forecasting accuracy enables discoms to schedule battery charging and discharging cycles with high precision, optimizing overall grid efficiency and minimizing financial penalties associated with unscheduled power exchanges.

Strategic Roadmap Toward the 2031 Capacity Goal
Achieving 92 GWh of energy storage by 2031 requires a structured rollout across multiple phases. Ministry officials and grid authorities will outline specific bidding guidelines, technical requirements, and tariff structures for upcoming auctions. Project sites will be selected based on proximity to major solar parks, wind corridors, and high-voltage transmission substations.
The expansion of grid storage is expected to generate significant demand for local equipment manufacturing and battery assembly plants. By establishing clear multi-year deployment targets, the government provides market clarity to battery cell manufacturers, engineering firms, and raw material suppliers, encouraging long-term domestic investments.
In addition to industrial growth, the scheme aims to reduce operational costs for state-owned power distribution companies. Discoms will no longer need to rely exclusively on costly thermal power plants operating on spinning reserve to handle sudden demand surges, thereby reducing peak power procurement expenses.
What Lies Ahead for Utilities and Power Developers
With Cabinet approval secured, state transmission utilities and private developers are preparing to participate in upcoming competitive bidding rounds under the new framework. Project developers must evaluate technology partnerships, land availability, and supply chain logistics to prepare viable tenders. Power utilities will need to adapt their grid operation protocols to integrate battery management systems seamlessly into daily operations.
As implementation guidelines are issued by regulatory authorities, focus will shift toward executing pilot projects and expanding manufacturing capacity. Stakeholders across the renewable energy supply chain will closely monitor auction schedules to secure funding allocations under this major initiative.
