SECI awards 2 GW solar-plus-storage; Reliance's NU Suntech wins 930 MW
Reverse-auction results show solar-plus-storage tariffs at ₹3.52/kWh — the economics of pairing PV with 4-hour storage.
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.
