India battery storage tariffs seen rising as higher costs squeeze low-priced projects

By Sethuraman N R

Tariffs for ​battery storage in India are expected to rise, developers and lenders said at ‌an industry event on Wednesday, as high input costs have made low-priced projects harder to sustain.

The South Asian nation is rapidly expanding battery storage to provide round-the-clock renewable power, with about 260 gigawatt-hours (GWh) of energy ​storage projects currently at various stages of development.

“Tariffs for standalone battery storage projects fell ​sharply over the last two years on expectations that battery cell costs ⁠would continue to decline,” said Debamalya Sen, president of the India Energy Storage Alliance (IESA).

“With costs ​now rising, the question is how many of those projects will survive,” he said during ​an event organised by IESA in New Delhi.

END OF CHINA INCENTIVES, IRAN WAR PUSHING UP BATTERY COSTS

Installed battery storage capacity rose more than 11-fold to 8.7 GWh in the first half of 2026 from 0.78 GWh ​at the end of 2025 and is expected to reach 10 GWh by the end ​of 2026, according to IESA.

That is still far lower than the renewable generation capacity of about 283 ‌GW, however.

The ⁠withdrawal of export incentives by China, the world’s largest battery supplier, along with rising prices of lithium, copper and aluminium tied to the Iran war have pushed up battery costs.

India’s top lender State Bank of India (SBI.NS), opens new tab said some projects that secured funding have not progressed as battery ​prices rose and suppliers ​no longer honoured ⁠earlier price commitments.

“In 2025, we saw the lowest (tariff) quote at 148,000 rupees ($1,548.85) per megawatt per month. At current battery prices, that is not ​sustainable,” said Asesh Chakrabarti, a State Bank of India deputy general manager, ​at a ⁠panel discussion.

Companies in India have been offering lower tariffs to win state government projects.

However, Mahindra Susten, the clean energy arm of the Mahindra Group, cautioned against a “race to the bottom” in tariffs.

“Tariffs … ⁠have to ​be realistic to ensure projects can secure financing, are ​built on time and to the required quality standards, and remain viable throughout their useful life,” said Mahindra Susten ​CEO Avinash Rao.
