BESS Deployment in India, 236 GWh Target, ₹2.65 Lakh Crore Investment, and 102 GWh in Tenders (2021 to 2026)

India is navigating a severe energy paradox, where surging economic growth and power demand clash with ambitious decarbonization goals. While the country is rapidly installing renewable energy and battery energy storage systems (BESS), coal remains the foundation of its power grid. The notion that batteries can displace coal-fired power plants is a misconception hindered by prohibitive economics, technical limitations, and deep-rooted supply chain vulnerabilities. For the next decade, India’s energy strategy will not be one of displacement but of pragmatic integration, where batteries supplement rather than supplant coal to maintain grid stability and fuel the nation’s growth.

Grid Stability Risks, India’s 253 GW Coal Fleet and BESS Integration Challenges

Despite a BESS tender boom that began in 2025, coal’s role as the primary source of baseload power and grid inertia remains secure, as BESS adoption is focused on providing ancillary services and managing peak demand, not displacing the core thermal fleet. The technical and operational realities of the Indian grid dictate a strategy of coexistence, where batteries are used to make the existing system more flexible.

• Between 2021 and 2024, BESS deployment in India was largely confined to small-scale pilots and demonstration projects. The strategic focus was on technology evaluation and understanding how storage could fit into a coal-dominated grid, while coal capacity continued to expand to meet rising demand.
• The period from 2025 to 2026 marked a significant strategic shift towards scaled deployment, signaled by approximately 102 GWh of BESS tenders issued in 2025 alone and supportive policies like the Viability Gap Funding (VGF) scheme. However, this surge in tendering has not translated to immediate operational capacity, which stood at a mere 500 MWh as of August 2025.
• The primary commercial application for BESS in India remains short-duration storage, typically for 2-4 hours. This is effective for absorbing midday solar surpluses and dispatching power during evening peaks, a function that helps manage intermittency but cannot replace the continuous, multi-day power delivery provided by India’s 253 GW coal fleet.
• A core technical barrier is the inflexibility of India’s thermal plants, most of which have a high minimum operating load of around 55%. This makes it difficult to ramp them down quickly during periods of high solar generation. Grid operators are often forced to curtail cheap renewable power instead, a situation that ironically reinforces coal’s must-run status and limits the displacement potential of renewables and storage.

$32 Billion Required, India BESS Market and Project Viability Concerns

The capital required to meet India’s official BESS targets is massive, and a trend of aggressive, low-tariff bidding that emerged in 2025 has created significant financial risk for project developers. This threatens to slow the pace of actual deployment despite strong market growth forecasts and clear policy ambitions.

• The Central Electricity Authority (CEA) projects a need for 236.2 GWh of battery storage by 2031-32 to support the integration of renewables. Achieving this target requires an estimated capital investment of ₹2.65 lakh crore (approximately $32 billion), a formidable financing challenge for the Indian market.
• Market forecasts published in 2026 project exponential growth, with Mordor Intelligence estimating the BESS market will grow from $2.05 billion in 2026 to $8.59 billion by 2031. This reflects the enormous demand for storage, but does not guarantee the bankability of individual projects.
• A critical execution risk became apparent in late 2025 when record-low bids in BESS tenders raised serious concerns about long-term project viability. As reported by Reuters, these low tariffs may not provide adequate returns on investment, making it difficult for developers to secure financing and casting doubt on whether tendered projects will reach completion.
• To mitigate this, the government’s VGF scheme offers to support up to 30% of the capital costs for BESS projects. While crucial for de-risking investments, the scheme may be insufficient to ensure profitability if competitive pressures continue to drive tariffs to unsustainable levels.

India vs. China, Global BESS Supply Chains and Domestic Manufacturing Gaps

India’s aggressive BESS deployment strategy, which accelerated in 2025, has exposed a critical geographic vulnerability: a heavy dependence on Chinese supply chains for cells and components. This has prompted a national push for domestic manufacturing that was largely absent in the 2021-2024 period, shifting the strategic calculus from simple procurement to supply chain security.

• Between 2021 and 2024, India’s BESS market was nascent, and reliance on imported components was an accepted cost of early adoption. The limited scale of deployment did not present a significant strategic risk.
• The massive scale-up of BESS tenders in 2025 and 2026 brought this dependency into sharp focus. India is heavily reliant on imports, especially from China, for finished battery cells, components, and critical raw materials like lithium.
• This creates significant geopolitical and economic risks, including vulnerability to supply chain disruptions and currency fluctuations. This contrasts sharply with the energy security India derives from its abundant domestic coal reserves, which insulate it from volatile global markets. The global battery supply chain is highly concentrated in China, with major players in adjacent sectors like solar module manufacturing, such as Jinko Solar, also expanding into the energy storage market.
• In response to this vulnerability, major Indian solar and energy firms announced accelerated investments in domestic BESS manufacturing throughout 2026. However, building a self-sufficient ecosystem will take several years, leaving India strategically exposed in the near term as it attempts to build out its storage capacity.

India BESS Pilots, Short-Duration Storage vs. Baseload Coal Power (2021 to 2026)

The technological application of BESS in India has matured from early-stage evaluation (2021-2024) to commercial-scale deployment of short-duration lithium-ion systems (2025-2026). However, this mature technology is technically incapable of providing the long-duration storage required to replicate, let alone replace, coal’s essential baseload function.

• The 2021-2024 period was characterized by technology assessment and small-scale pilots designed to validate the role of batteries in the Indian grid context.
• From 2025 onwards, the market has standardized around commercially proven Lithium-ion Phosphate (LFP) battery chemistry, which is optimized for 2-4 hour discharge cycles. This technology is highly effective for managing the “duck curve” by absorbing excess solar power and dispatching it to meet evening peak demand.
• The fundamental technology gap is the absence of commercially viable and cost-effective long-duration energy storage (LDES). Current BESS solutions cannot provide power for multiple days or across seasons, which is necessary to ensure grid reliability during long periods of low renewable generation, such as the monsoon season.
• A key strategic development in September 2025 was the launch of government-led pilot programs to co-locate BESS at existing coal-fired power plants. This signals a pragmatic shift towards hybridizing assets, using batteries to improve the flexibility and efficiency of the existing coal fleet rather than attempting to replace it outright.

SWOT Analysis, India’s BESS Market Strengths and Coal Dependency Risks

India’s BESS market is defined by a powerful combination of strong government-led growth drivers and significant execution risks. While opportunities for expansion are immense, fundamental economic and technical vulnerabilities continue to reinforce the country’s reliance on coal for near-term energy security.

India’s 2027 Outlook: BESS Integration with the 253 GW Coal Fleet

For the next one to two years, the primary function of BESS in India will be to serve as a grid-balancing tool and renewable energy firming agent, not a direct agent of coal displacement. The strategy is centered on integration and system enhancement, with the focus on making a renewable-heavy grid workable alongside the existing thermal fleet.

• If this happens: If the government’s VGF scheme and other de-risking policies prove effective in ensuring the bankability of projects awarded in the 2025-2026 tenders despite low tariff discoveries.
• Watch this: The successful financial closure and start of construction for the first wave of large-scale BESS projects (1 GWh or larger). This will be the most critical signal of the market’s transition from ambitious targets to tangible, on-the-ground execution.
• These could be happening: An acceleration of hybrid projects that co-locate batteries with both solar farms and existing coal plants. This model is gaining traction as the most pragmatic approach to enhancing grid flexibility, improving the efficiency of thermal assets, and absorbing more renewable energy without major system overhauls. The displacement of coal plants will remain off the table until a breakthrough in affordable, long-duration storage becomes commercially viable at Indian price points.
