New Delhi, May 12 — Reliance Power on Monday announced a significant boost to its renewable energy ambitions, with its subsidiary Reliance NU Energies securing a 350 MW solar power project integrated with a 175 MW/700 MWh battery energy storage system (BESS) from SJVN Ltd.
The project, awarded under SJVN’s tariff-based competitive bidding process, will deliver a four-hour daily discharge window and offer 175 MWh of backup power. The winning bid was placed at a competitive fixed tariff of Rs 3.33 per kWh for a 25-year term, making it one of the most cost-efficient renewable energy projects in India’s transition landscape.
Largest Allocation in SJVN’s 1,200 MW Tender
Reliance NU Energies achieved the most significant allocation from SJVN’s 1,200 MW solar + 600 MW/2,400 MWh BESS tender connected to the Inter-State Transmission System (ISTS). The tender witnessed participation from 19 bidders, with 18 qualifying for the final e-reverse auction. The project will be developed on a Build-Own-Operate (BOO) basis, adhering to the standard bidding guidelines laid out by the Ministry of Power.
Once commissioned, the project will enhance Reliance Power’s clean energy portfolio with 600 MWp of solar PV capacity and 700 MWh of storage. This strengthens the company’s leadership in the integrated Solar + BESS segment, with a total pipeline now at 2.5 GWp of solar and 2.5 GWh of storage.
Strategic Pivot to Renewable Energy
