India BESS Pipeline Hits 92 GWh, Solar-Plus-Storage Tariff at INR 3.12/kWh
Pipeline Expansion
India's battery energy storage system (BESS) pipeline has reached 92 GWh across various stages of tendering, development, and commissioning, according to data from IEEFA and Ember. This represents a tenfold increase from just two years ago, driven by SECI and state-level tenders that bundle solar generation with multi-hour storage requirements.
The most significant development is the continued decline in solar-plus-storage tariffs. Recent auctions have seen solar with 6-hour battery storage quoted at INR 3.12 per kWh, a tariff that undercuts new coal-fired generation and competes directly with existing thermal plants during peak evening hours.
Technology and Cost Drivers
Lithium iron phosphate (LFP) battery costs have fallen below $80 per kWh at the cell level, making 4-6 hour duration storage economically viable for Indian grid applications. Chinese battery manufacturers continue to dominate supply, though domestic cell manufacturing under the ACC PLI scheme is expected to begin contributing meaningful volume by late 2026.
What It Means
The 92 GWh pipeline and sub-INR 3.15 tariffs mark a turning point for Indian grid storage. For the first time, dispatchable solar is cost-competitive with baseload thermal generation. This fundamentally changes the economics of evening peak power supply and strengthens the case for accelerated coal plant retirement schedules.
