Tariffs for battery storage systems in India are set to increase, driven by rising input costs that are squeezing the margins of low-priced renewable energy projects.
The adjustment threatens to undermine the economic viability of several planned installations, potentially slowing the deployment of critical grid infrastructure.
The tariff hike comes as India’s installed battery storage capacity has surged more than 11-fold to 8.7 GWh in the first half of 2026, up from 0.78 GWh at the end of 2025, according to the Indian Energy Storage Association (IESA).
The industry had projected reaching 10 GWh by the end of 2026, but the new cost pressures may complicate achieving that target.
This development adds to a broader set of headwinds facing India’s economic outlook.
The country is already grappling with inflationary pressures linked to a weak monsoon forecast, which has increased scrutiny on the Reserve Bank of India’s policy path.
