Most of what has happened in Indian battery storage over the last three years traces back to one thing: cells got cheap. Tariffs that looked impossible in 2023 are being bid today, and the reason is not clever financial engineering. It is the cost of the cells.
Here is where prices actually stand, and what a buyer should do about it.
The numbers
Average lithium-ion pack prices fell about 8 per cent in 2025 to roughly $108 per kWh — around 93 per cent below 2010 levels. That is the headline figure across all applications.
More relevant if you are buying storage: pack prices for stationary storage dropped to about $70 per kWh in 2025, roughly 45 per cent lower than the year before.
At the cell level, the lowest LFP cell price observed was around $36/kWh, with the lowest LFP pack price around $50/kWh. Leading mainstream manufacturers including CATL and BYD have been pushing LFP cell costs down toward the $44–$50/kWh range.
For 2026, BloombergNEF expects a further decline of roughly 3 per cent in pack prices across segments — raw material costs rising, but continued adoption of LFP as the lower-cost chemistry more than offsetting it. The chemistry trade-off itself is covered in LFP versus NMC.
Why stationary storage became the cheapest segment
This is a genuine reversal, and the logic is worth following.
An electric vehicle pays a premium for energy density — every kilogram and every litre matters, because the battery has to move itself around. A stationary system on a concrete pad has no such constraint. It can use cells optimised purely for cost and cycle life, in a heavier, bulkier, cheaper format.
Once LFP matured enough to deliver the cycle life stationary storage needs, the segment that cared least about weight became the segment that paid least. That is why storage prices fell 45 per cent in a year while the overall average fell 8 per cent.
Region matters
Average pack prices were lowest in China at about $84/kWh, with North America roughly 44 per cent higher and Europe about 56 per cent higher, reflecting local production costs and dependence on imported cells.
India sits on the import-dependent side of that divide. Domestic cell manufacturing accounts for a very small share of Indian demand, which is the subject of India’s battery import dependence. What that means in practice: an Indian project pays a landed cost, not a factory-gate one — freight, duties, currency, and local balance of plant all sit on top. Our guides to GST and customs duty on BESS and BESS prices in India cover how that builds up.
What falling cells do and do not solve
What they do. They explain the collapse in discovered capacity tariffs — from around ₹2.3 lakh/MW/month on a large Gujarat award to roughly ₹1.48 lakh/MW/month in an Andhra Pradesh tender. They make augmentation cheaper to plan for, since future replacement cells should cost less than today’s. And they make behind-the-meter projects viable at sites where the arithmetic did not work two years ago.
What they do not. Cells are a large share of equipment cost but a smaller share of project cost. The power conversion system, transformers, civil works, land, grid connection, insurance and financing do not fall with cell prices. Halving the cell price does not halve the project.
They also do not reduce execution risk, which is where Indian projects most often lose money — commissioning delays add to the cost of capital regardless of what the cells cost.
Should you wait?
Generally, no.
A further 3 per cent or so on the cell line is small against a year of foregone bill savings or contracted revenue. The decline also depends on raw material prices that have been rising — the fall in pack prices happened despite rising metal prices, carried by chemistry shift and manufacturing scale rather than by cheaper inputs. Those levers do not extend indefinitely.
The sharper question is not when to buy but what to buy. A cheap cell inside a poorly cooled system with a weak degradation guarantee is not a bargain, and the price gap between good and mediocre equipment is now smaller than the performance gap between them.
What this means for you
- If you are a C&I buyer: falling prices have probably already moved your site from marginal to viable. Rerun the numbers if you last looked more than a year ago — our savings calculator is the quickest way to check.
- If you are a developer: model augmentation cost with a declining price assumption, but a conservative one. Assuming today’s decline rate continues for a decade is how a fifteen-year model quietly becomes fiction.
- If you are comparing quotes: insist on delivered, installed cost per usable kWh, not cell or pack price. Headline cell prices are not what anyone actually pays.
- If you are buying now: compare guaranteed capacity at year ten rather than price on day one. Our product range states usable energy and guarantees plainly, and our team can price a specific configuration — get in touch.
