Sunsure Energy Wins Landmark NVVN 250 MW BESS Auction
In a milestone for India’s renewable energy sector, Sunsure Energy and Enerica Infra 3 secured rights to develop 250 MW/1,000 MWh standalone battery energy storage systems (BESS) under NTPC Vidyut Vyapar Nigam’s (NVVN) auction. This project reflects the accelerating shift toward hybrid solar-storage solutions nationwide.
Why This Grid-Scale Storage Auction Matters
The NVVN’s build-own-operate model ensures developer accountability, mirroring successful storage approaches seen in California and Texas where BESS operators are transforming grid reliability. This auction sets a precedent for India’s energy transition.
Solving Solar’s Intermittency Challenge
By storing noon solar surges for evening demand, these 1,000 MWh systems can power ~33,000 homes for 24 hours during outages. Similar to South Africa’s recent 123MW BESS project, this helps stabilize grids while reducing fossil fuel dependence.
Project Economics and Policy Support
- ₹3.06 lakh/MW/month tariff sets new benchmark
- Waived transmission charges improve ROI
- Banking reforms allow energy “parking”
The Future: Hybrid Power Dominance
As seen in Telangana’s agrivoltaic expansion, expect solar-storage hybrids to dominate future tenders. This NVVN auction paves the way for similar projects nationwide.
