SECI awarded 2 GW of solar-plus-storage capacity in a reverse auction, with Reliance's NU Suntech taking the largest share at 930 MW at a bidding price of ₹3.53/kWh. The other four winners bid ₹3.52/kWh.
The results
| Winner | Solar capacity | |---|---| | Reliance NU Suntech | 930 MW | | NTPC | (portion) | | Solarcraft Power India | (portion) | | Hero Solar Energy | (portion) | | Sembcorp | 150 MW + 300 MWh BESS |
- Storage pairing: 1 GW/4 GWh energy storage tendered alongside the solar
- Requirement: 0.5 MW/2 MWh storage per MW of solar
- PPAs: 25-year terms with SECI as intermediary
Sub-₹3.6/kWh solar-plus-storage tariffs are the headline number — they demonstrate that pairing PV with 4-hour storage is becoming cost-competitive with firm conventional power in the daytime window.
Signal
Solar-plus-storage is now the default procurement format for Indian renewable tenders. For battery and storage players, the paired format is where volume lives — pure standalone BESS is still a smaller, newer channel.
₹3.52/kWh solar-plus-storage is the price point that makes the storage conversation real in India.Advertisement
