India’s power transmission grid is standing at the precipice of the most profound structural transformation since the inception of the national synchronous grid. With more than 210 GW of non-fossil generation capacity already synchronized and national targets demanding 500 GW of non-fossil capacity by 2030, the fundamental operational challenge of the Indian power system has shifted decisively: the historical bottleneck was raw capacity generation; the contemporary bottleneck is temporal flexibility and dispatchability.
Solar photovoltaics generate power during daytime irradiance windows that do not coincide with the nation’s steepest electricity demand peak, which occurs between 18:30 and 22:30 hours. Without utility-scale energy storage, this divergence creates catastrophic solar curtailment risks during the afternoon and forces distribution companies (DISCOMs) to rely on expensive, carbon-intensive peaking thermal generation or volatile spot-market purchases on the Indian Energy Exchange (IEX).
To overcome this structural barrier, the Government of India has moved battery energy storage from experimental pilot demonstrations to a core fiscal and statutory priority. Between the expansion of the original Viability Gap Funding (VGF) scheme, the dedicated ₹5,400 crore allocation from the Power System Development Fund (PSDF) for 30 GWh of storage, a 100% Inter-State Transmission System (ISTS) charge waiver operative through June 30, 2028, and statutory Energy Storage Obligations (ESO) binding on all obligated entities, over ₹9,160 crore in cumulative public viability support is actively transforming the energy storage landscape.
The following metrics summarize the verified regulatory, fiscal, and operational status of India’s BESS ecosystem as of mid-to-late 2026 based on official notifications from the Ministry of Power, MNRE, and CEA:
Supporting 43.8 GWh of BESS capacity across India via ₹3,760 Cr initial budgetary outlay (13.8 GWh) and ₹5,400 Cr PSDF tranche (30 GWh).
₹5,400 Cr approved June 9, 2025; ₹18 lakh/MWh support allocated across 15 states (25 GWh) and NTPC Ltd. (5 GWh); 22.43 GWh LoAs issued.
100% interstate transmission charge waiver for co-located BESS commissioned on or before June 30, 2028, locked for 25 years (MoP order dated 10.06.2025).
Execution reality: only ~1.4 GWh commissioned (Ola Electric) vs ₹18,100 Cr target; zero disbursements due to stringent Domestic Value Addition hurdles.
Basic Customs Duty waived on lithium carbonate, oxide, hydroxide, and cell machinery, lowering upstream manufacturing capex barriers.
Mandatory Energy Storage Obligation reaching 2.5% in FY 2026-27 and 4.0% by 2029-30 under the Electricity Act, requiring ≥85% RE charging annually.
A Battery Energy Storage System is an integrated electrochemical infrastructure asset engineered to absorb electrical energy from generation sources or the grid, store that energy chemically within battery cells, and discharge electrical power back into the grid or local load on demand. A utility-scale BESS is far more than a container of battery cells; it comprises five critical subsystems:
According to the Central Electricity Authority’s (CEA) National Electricity Plan (Generation Vol. 1) and optimal generation capacity mix studies, India will require 411.4 GWh (73.93 GW) of total energy storage capacity by 2031-32 to maintain national grid stability. This required capacity is divided between:
India’s solar generation profile peaks between 11:00 and 14:00 hours, creating a massive midday generation belly. Conversely, urban and industrial cooling demands, combined with agricultural pumping cycles, drive an acute evening peak between 18:30 and 22:30 hours. The net load curve resembles a classic “duck curve.” Without grid-scale storage, the grid operator (Grid-India / NLDC) faces two equally damaging choices:
BESS provides sub-second synthetic inertia and four primary grid services: Peak Shifting & Energy Arbitrage (storing daytime solar for evening discharge), Fast Frequency Response (reacting within 200 milliseconds to arrest grid frequency deviations from the 50 Hz band), Transmission Deferral (alleviating localized network bottlenecks), and Renewable Energy Firming (converting intermittent solar/wind into dispatchable Round-The-Clock power profiles).
It is vital for market participants to distinguish between distinct policy verticals:
The following structured matrix outlines every verified central policy mechanism governing battery energy storage in India as of mid-to-late 2026:
| Scheme / Policy | Authority | Purpose & Support | Beneficiaries | Key Conditions | Verified Status | Reference |
|---|---|---|---|---|---|---|
| Initial BESS VGF Scheme (2023) | Ministry of Power / MNRE | Up to 40% Capex subsidy (max ₹27 L/MWh); ₹3,760 Cr outlay for 13.8 GWh | Grid-scale BESS developers | 85% capacity to DISCOMs; 20% DCR; 5 disbursement tranches | Active / In Construction | Cabinet 06.09.23 |
| PSDF BESS VGF Tranche (2025) | Ministry of Power / NLDC | ₹5,400 Cr from PSDF; benchmark ₹18 L/MWh for 30 GWh capacity | 15 State DISCOMs (25 GWh) & NTPC (5 GWh) | Supplying non-solar peak hours; competitive bidding; grid compliance | 22.43 GWh Awarded | MoP 09.06.25 |
| ISTS Transmission Waiver | Ministry of Power / CERC | 100% waiver of interstate transmission charges for 25 years | Co-located BESS & Hydro PSP projects | Connected at same ISTS sub-station; COD ≤ 30 June 2028; interstate consumption | Extended to 2028 | Order 10.06.25 |
| Advanced Chemistry Cell (ACC) PLI | Ministry of Heavy Industries | Sales-linked incentive; ₹18,100 Cr outlay for 50 GWh cell production | Giga-factory cell manufacturers | Min 25% DVA in 2 yrs, rising to 60% in 5 yrs; min 250 Wh/kg density | 1.4 GWh Active | MHI ACC PLI |
| Energy Storage Obligations (ESO) | Ministry of Power / SERCs | Statutory purchase mandate under Electricity Act (2.5% in FY27 → 4% by FY30) | DISCOMs, Open Access, Captive (≥1 MW) | Stored energy must be charged ≥85% from renewable energy annually | Statutory Mandate | Order 22.07.22 |
| Critical Minerals Customs Relief | Ministry of Finance (CBIC) | 0% BCD on lithium carbonate, oxide, hydroxide & cell capital goods | Cell makers & chemical refiners | Direct industrial manufacturing use; end-use bond compliance | Enacted | Budget 2026-27 |
| Critical Mineral Recycling Incentive | Ministry of Mines | 20% Capex subsidy + performance-linked Opex sales subsidy (₹1,500 Cr outlay) | Chemical battery recyclers | Must perform hydrometallurgical chemical extraction; shredding alone excluded | 58 Firms Selected | Mines Guidelines |
| Battery Waste Management Rules | MoEFCC / CPCB | Extended Producer Responsibility (EPR) recycling & recovery mandates | Battery producers, pack assemblers, importers | Mandatory ≥70% recovery of Li, Co, Ni by FY 2026-27; online EPR portal filing | Statutory Law | BWMR 2022 |
Battery storage capital expenditure, while falling globally, remains a significant hurdle for Indian power procurers. A utility-scale BESS carries a capital expenditure of roughly ₹1.35 to ₹1.60 crore per MWh (inclusive of lithium-ion cells, containers, PCS, and grid interconnection). When translated into a Levelized Cost of Storage (LCOS), an unsupported BESS requires a spread of ₹8.00 to ₹10.00 per kWh to yield a commercially acceptable project IRR. Indian distribution companies, already financially constrained, cannot sign off-take agreements at such tariffs.
Viability Gap Funding is a targeted capital grant provided by the central government to bridge the gap between what a BESS costs to build and what it can earn at a tariff acceptable to DISCOMs. VGF directly reduces the debt and equity burden of the developer, driving the resulting storage tariff down into the target corridor of ₹5.50 to ₹6.60 per kWh.
India’s VGF support operates across two distinct, complementary programs that must not be confused:
Together, these two pillars represent a cumulative public commitment of ₹9,160 crore (~$1.10 billion) supporting 43.8 GWh of battery storage capacity.
VGF is never paid as an upfront grant. Implementing agencies (SECI, NTPC, SJVN) disburse funds across five strictly audited verification milestones:
The following table provides an exact side-by-side financial breakdown of India’s two operational VGF schemes:
| Parameter | Initial BESS VGF Scheme | PSDF BESS VGF Scheme | Combined Program |
|---|---|---|---|
| Notification Date | 6 September 2023 (Cabinet) | 9 June 2025 (Ministry of Power) | 2023 – 2026 Multi-Phase |
| Funding Source | Central Budgetary Support | Power System Development Fund (PSDF) | Consolidated Public Finance |
| Financial Allocation | ₹3,760 Crore (Direct Support) | ₹5,400 Crore | ₹9,160 Crore (~$1.10 Billion) |
| Supported Storage Capacity | 13.8 GWh (Expanded from 4 GWh) | 30.0 GWh | 43.8 GWh Cumulative |
| Benchmark Support Quantum | Up to ₹27 Lakh / MWh (Max 40% Capex) | Up to ₹18 Lakh / MWh | Tiered Benchmark Structure |
| Capacity Distribution | Central competitive tenders (SECI / NTPC) | 25 GWh to 15 States; 5 GWh to NTPC | National Grid & State Blend |
| Domestic Content Rule | 20% DCR (including EMS) added Dec 2025 | 20% DCR mandatory across all states | Mandatory 20% DCR Nationwide |
| Target Levelized Tariff | ₹5.80 – ₹6.60 / kWh | ₹5.20 – ₹5.90 / kWh | ₹5.20 – ₹6.60 / kWh |
| Implementation Progress | Under construction across 4 states | Letters of Award for 22.43 GWh issued | Active Construction & LoAs |
The Inter-State Transmission System (ISTS) is India’s national high-voltage bulk transmission highway, operated by the Power Grid Corporation of India Limited (POWERGRID) and regulated by the Central Electricity Regulatory Commission (CERC). Under normal transmission service agreements, power injected into the ISTS attracts transmission and wheeling charges ranging from ₹1.20 to ₹1.80 per kWh depending on regional distances and transmission loss factors.
For an energy storage project, transmission charges present a severe double-jeopardy penalty: charges are incurred when buying electricity to charge the battery, and charges are incurred again when discharging stored electricity to the off-taker. Subjecting storage to full ISTS charges would inflate the delivered cost of storage by ₹2.50 to ₹3.50/kWh, rendering interstate solar-plus-storage projects commercially unviable.
Recognizing this economic barrier, the Ministry of Power issued Order No. 23/12/2016-R&R on June 10, 2025, substantially amending earlier transmission waiver provisions:
Projects commissioned on or before June 30, 2028 lock in the 100% waiver for a period of 25 years from their Commercial Operation Date (COD). For projects commissioned after June 30, 2028, a graded annual phase-out applies:
Practical Takeaway: This hard deadline makes commissioning speed a direct financial variable. Developers structuring hybrid solar-plus-storage bids in 2026 must ensure that substation allocation, land acquisition, and EPC procurement are scheduled to achieve COD before June 30, 2028 to lock in 25 years of zero-cost transmission.
To reduce dependency on imported battery cells—predominantly sourced from China, South Korea, and Taiwan—the Union Cabinet approved the Production Linked Incentive (PLI) Scheme for National Programme on Advanced Chemistry Cell (ACC) Battery Storage in May 2021, managed by the Ministry of Heavy Industries (MHI):
While the policy vision is ambitious, market reality reveals a significant execution bottleneck that developers and investors must recognize:
To alleviate the cost penalties associated with domestic cell manufacturing, the Ministry of Finance enacted significant tariff concessions in recent Union Budgets:
The ACC PLI is an industrial manufacturing incentive paid to factory owners who fabricate battery cells from raw chemicals. The BESS VGF is an infrastructure capital grant paid to project developers who install completed storage systems on the electrical grid. Project developers cannot apply for PLI subsidies; they benefit indirectly only if domestic cell prices eventually fall below imported cell tariffs.
In July 2022, the Ministry of Power, exercising regulatory powers under Section 86(1)(e) of the Electricity Act 2003 and the National Tariff Policy, formally decoupled and notified the Energy Storage Obligation (ESO) trajectory up to the year 2029-30.
Historically, state utilities met their Renewable Purchase Obligations (RPO) by procuring standalone solar or wind energy. However, because solar generation ceases at sunset, DISCOMs were able to meet paper compliance targets while failing to meet real-time grid balancing needs. The ESO mandate legally compels electricity distribution companies, open-access consumers, and captive power producers to procure a defined percentage of their total electricity consumption specifically from energy storage systems.
| Financial Year | Mandatory ESO Target | Regulatory & Compliance Notes |
|---|---|---|
| FY 2023-24 | 1.00% | Initial compliance year; at least 85% of energy stored charged from RE annually |
| FY 2024-25 | 1.50% | Audited via State Electricity Regulatory Commission (SERC) tariff petitions |
| FY 2025-26 | 2.00% | Applies to DISCOMs, Open Access industrial consumers, and Captive Plants (≥1 MW) |
| FY 2026-27 (Current) | 2.50% | Mandatory procurement enforced; compliance audits integrated into DISCOM tariff orders |
| FY 2027-28 | 3.00% | Co-located BESS, standalone utility storage, and Pumped Hydro eligible |
| FY 2028-29 | 3.50% | Dedicated peak-hour storage dispatch required across major industrial states |
| FY 2029-30 | 4.00% | Full integration supporting national 500 GW non-fossil capacity target |
While central policies provide the macro-fiscal architecture, electricity is a Concurrent Subject under the Indian Constitution. State Electricity Regulatory Commissions (SERCs) and state governments control distribution licensing, wheeling tariffs, and cross-subsidy surcharges. The following comparison table details states with active, verified storage frameworks:
| State | Governing Policy / Order | Incentive & Support Mechanism | Beneficiaries | Operative Period | Status & Citation |
|---|---|---|---|---|---|
| Gujarat | Gujarat RE Policy 2023 & GUVNL Bids | 100% banking concession for storage-paired solar/wind; dedicated state VGF top-up tenders | Grid-scale BESS & hybrid developers | Valid through 2028 | >1.5 GWh In Construction |
| Rajasthan | Rajasthan RE Policy 2023 | 50% concession on intra-state transmission & wheeling for 7 years; 25% banking facility | Utility-scale ESS, hybrids, solar parks | Operative through 2028 | Active Hybrid Pipeline |
| Maharashtra | MERC RE Tariff Regulations 2025-26 | Peak-tariff premium off-take guarantees; cross-subsidy surcharge waiver for green storage wheeling | MSEDCL suppliers, C&I open access | 2025 – 2030 | 500 MW / 1 GWh Tendered |
| Karnataka | Karnataka RE Policy 2022-2027 | Pilot storage capital subsidies; prioritized grid injection at Pavagada & major substations | Grid-scale developers, storage funds | Valid through 2027 | 100 MW Pilots Live |
| Tamil Nadu | Tamil Nadu RE Policy & TANGEDCO ESS | Substation co-located BESS allocations to eliminate wind curtailment in southern districts | Substation storage developers & wind IPPs | 2024 – 2028 | 500 MW Substation Bids |
| Andhra Pradesh | AP Integrated Clean Energy Policy 2024 | Concessional land lease rates for BESS; 100% stamp duty reimbursement for storage units | Utility storage & manufacturing units | Valid through 2029 | Focus on Hybrid & PSP |
| Uttar Pradesh | UP Solar Energy Policy 2022-2027 | Capital subsidy of ₹50 lakh per MW for initial 4-hour utility BESS pilot installations | First-mover utility storage developers | Operative through 2027 | Pilot Solar Park Storage |
Note: For states not listed above (e.g., Bihar, West Bengal, Odisha), dedicated storage cash subsidies have not been independently verified; projects in those states rely primarily on central VGF and ISTS frameworks.
Understanding where your organization sits in the value chain is critical for targeting the right incentives. The following breakdown maps opportunities and constraints across seven key stakeholder groups:
Primary Opportunities: Eligibility to bid in SECI, NTPC, and SJVN tenders for VGF support covering up to 40% of capital costs; 12-to-25 year long-term Capacity Service Agreements (CSAs) providing fixed monthly availability payments.

Before committing capital to a battery storage development in India, developers and investors should follow this rigorous 10-step due-diligence workflow:
Determine whether the asset is a standalone utility BESS, an integrated solar/wind-plus-storage hybrid, or a behind-the-meter C&I facility.
Identify whether the project targets central support (MoP VGF, SECI auction, ISTS waiver) or state-level incentives (state banking concessions, intra-state wheeling waivers).
Check whether the scheme is currently open for bidding on portals such as ISN-ETS (SECI) or CPPP. Never rely on historic scheme announcements.
Verify net worth requirements (≥₹1.50 to ₹2.00 Cr/MW of bid capacity) and technical experience criteria specified in RfS documents.
Confirm bay availability from CTUIL or STU. For ISTS waiver eligibility, verify connection at the shared pooling substation before June 30, 2028.
Audit supply chains to ensure at least 20% domestic value addition (including Indian EMS software, power transformers, and local container integration) to safeguard VGF disbursement.
Verify whether the tender is a Capacity Service Agreement (availability payment model) or an energy-tariff model. Confirm compliance with the 85% DISCOM capacity dedication mandate.
Model realistic Capex, cell degradation curves (typically 2.0% to 2.5% p.a.), round-trip efficiency (RTE ~85-88%), and battery augmentation schedules at year 7–8.
Confirm contract terms, dispute resolution mechanisms, and escrow payment security protections with SECI, NTPC, or the relevant state utility.
Cross-check all applicable tariff orders, CERC/SERC regulations, and customs notifications before executing binding EPC or financing contracts.
To illustrate how Viability Gap Funding and transmission waivers impact commercial returns, the following techno-economic model evaluates a representative utility-scale BESS project in India:
Disclaimer: Illustrative techno-economic model based on standard industry assumptions. Actual project financial returns depend on competitive e-reverse auction outcomes, site-specific geotechnical conditions, equipment supply contracts, and off-taker payment security.
India’s transition to a 411 GWh storage-backed grid is driving an unprecedented demand for specialized engineering and techno-commercial talent. Conventional solar PV expertise—such as DC string sizing and basic solar civil design—is necessary but insufficient. Modern BESS projects demand deep multidisciplinary proficiencies spanning electrochemical engineering, power electronics, thermodynamics, and high-voltage grid interconnection.
As India’s premier specialized technical training institution in renewable energy and clean technologies, the Indian Institute of Solar Energy (IISE) bridges the critical gap between government policy allocations and industry-ready engineering skills. With state-of-the-art laboratory facilities at its Mumbai campus, IISE delivers hands-on, practical education mapped directly to the technical demands of the BESS sector.
Detailed, verified answers to the most common regulatory, technical, and financial questions regarding battery energy storage systems in India:
India’s 2026 BESS framework is an integrated strategy combining Viability Gap Funding (VGF) for grid-scale deployment, statutory Energy Storage Obligations (ESO) binding on power utilities, an Inter-State Transmission System (ISTS) charge waiver operative through June 30, 2028, customs duty exemptions on critical minerals, and the ACC PLI manufacturing scheme. Together, these policies aim to build 411 GWh of storage capacity by 2031-32 as outlined in the CEA National Electricity Plan.
Direct cash subsidies exist exclusively for grid-scale utility BESS projects selected through competitive e-reverse auctions conducted by agencies such as SECI, NTPC, and state utilities under the Ministry of Power’s VGF schemes. There is no universal direct cash subsidy for individual residential battery purchases or private off-grid setups, which are governed by state net-metering and rooftop solar regulations.
VGF is a capital grant that covers up to 40% of the project capital cost of a utility BESS, designed to lower the levelized storage tariff to an affordable range (₹5.50–6.60/kWh) for distribution companies. A total of over ₹9,160 crore has been committed across two phases: ₹3,760 crore under the initial budgetary scheme (supporting 13.8 GWh) and ₹5,400 crore under the PSDF-backed program (supporting 30 GWh).
Approved on June 9, 2025 by the Ministry of Power, this scheme draws funding from the Power System Development Fund (PSDF) to support 30 GWh of storage with a benchmark viability grant of ₹18 lakh per MWh. It allocates 25 GWh to 15 identified states to meet local grid integration requirements and 5 GWh to NTPC Ltd. to optimize transmission lines and supply power during non-solar hours. Over 22.4 GWh of capacity has already received Letters of Award.
No. Central BESS VGF funding is strictly restricted to utility-scale, grid-connected storage assets that allocate at least 85% of their capacity to public distribution companies. Residential rooftop solar owners are supported under the PM Surya Ghar Muft Bijli Yojana, which subsidizes rooftop solar generation but does not provide capital grants for standalone battery storage packs.
Under Ministry of Power Order No. 23/12/2016-R&R dated June 10, 2025, a 100% waiver of Inter-State Transmission System charges applies to co-located BESS projects commissioned on or before June 30, 2028, provided the electricity is consumed outside the commissioning state. Projects commissioned before this date lock in zero transmission charges for 25 years. After June 30, 2028, the waiver phases out by 25% annually.
Introduced by the Ministry of Power in December 2025, the DCR mandates that a minimum of 20% of the total capital cost of a VGF-funded BESS project must consist of domestically manufactured components. This includes the Energy Management System (EMS) software, power transformers, switchgear, structural containers, and balance-of-plant systems. Meeting this requirement is a prerequisite for subsidy disbursement.
The ACC PLI scheme targets 50 GWh of domestic cell manufacturing capacity under the Ministry of Heavy Industries. However, execution has lagged: as of late 2025, only approximately 1.4 GWh had been commissioned (by Ola Electric), and zero incentive disbursements had been released due to the difficulty of meeting strict Domestic Value Addition (DVA) thresholds (minimum 25% within two years). Reliance New Energy is progressing on its 10 GWh allocation in Jamnagar.
ESOs are statutory purchase mandates notified by the Ministry of Power under the Electricity Act 2003. They require distribution companies (DISCOMs), open-access industrial power buyers, and captive generating plants (>1 MW) to procure a specified percentage of their total electricity from energy storage systems. The trajectory mandates 2.5% in FY 2026-27, escalating to 4.0% by FY 2029-30, with a strict rule that at least 85% of the stored energy must originate from renewable generation annually.
Union Budget measures have exempted key critical mineral inputs—including lithium carbonate, lithium oxide, and lithium hydroxide—from Basic Customs Duty (lowered to 0% from 7.5%). In addition, capital goods and specialized machinery imported for setting up lithium-ion cell manufacturing and BESS assembly facilities enjoy full customs duty exemptions.
Gujarat leads in utility procurement through GUVNL tenders with 100% banking concessions. Rajasthan provides a 50% concession on intra-state transmission charges for 7 years under its 2023 RE Policy. Maharashtra guarantees peak-tariff off-take through MERC regulations, while Karnataka and Tamil Nadu are executing large-scale substation co-located storage tenders to eliminate renewable curtailment.
Notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) in 2022, the rules mandate Extended Producer Responsibility (EPR) for battery manufacturers and importers. By FY 2026-27, producers and recyclers must achieve mandatory recovery of at least 70% of critical materials (lithium, cobalt, nickel) from spent battery packs and register all transactions on the Central Pollution Control Board (CPCB) online portal.
With VGF support (₹18 to ₹27 lakh/MWh) and the ISTS transmission waiver, the levelized cost of a 2-hour to 4-hour utility BESS in India currently ranges between ₹5.50 and ₹6.60 per kWh. Unsupported standalone commercial systems without subsidies typically experience an LCOS between ₹8.50 and ₹11.00 per kWh depending on cell chemistry, financing rates, and utilization cycles.
High-demand competencies include lithium cell chemistry and degradation modeling, Battery Management System (BMS) firmware architecture, 1500V Power Conversion System (PCS) commissioning, Energy Management System (EMS) SCADA programming, liquid-cooling thermal design, and compliance with safety standards such as IS 16270, UL 9540A, and NFPA 855.
