Reliance Power Limited, through its wholly owned subsidiary Reliance NU Energies Private Limited, has secured the largest allocation in SJVN Limited’s recent tariff-based competitive bidding process. The allocation includes 350 MW of solar power generation capacity along with a 175 MW/700 MWh Battery Energy Storage System (BESS).
This development adds 600 MWp of solar PV capacity and 700 MWh of energy storage to Reliance Power’s renewable energy portfolio. With this addition, the company’s total clean energy pipeline reaches 2.5 GWp of solar capacity and over 2.5 GWh of BESS, establishing it as the largest player in India’s integrated Solar + BESS segment.
The project was awarded at a tariff of INR 3.33 per kWh, fixed for a 25-year term. The Letter of Award (LoA) from SJVN is currently awaited. This allocation is part of a broader 1,200 MW solar and 600 MW / 2,400 MWh BESS Inter-State Transmission System (ISTS)-connected tender floated by SJVN, a Navratna Public Sector Enterprise. The tender received strong interest, with participation from 19 companies and oversubscription by more than four times.
As per tender conditions, the project includes a minimum daily discharge window of four hours, aimed at providing reliable peak power to state distribution companies (Discoms). It will be executed under a build-own-operate (BOO) framework, adhering to the Ministry of Power’s standard bidding guidelines.
In a related development, Reliance Power’s other 100% subsidiary, Reliance NU Suntech Private Limited, has signed a 25-year Power Purchase Agreement (PPA) with the Solar Energy Corporation of India (SECI). The agreement covers the development of a 930 MW solar project paired with a 465 MW/1860 MWh BESS. The project will operate at a fixed tariff of INR 3.53 per kWh for the entire duration and represents an estimated investment of up to INR 10,000 crore.
Upon commissioning, this will be Asia’s largest integrated Solar + BESS installation, further contributing to grid stability and long-term clean energy supply.
These project wins reflect Reliance Power’s strategic focus on scalable renewable energy infrastructure, with a growing emphasis on hybrid solar and storage systems that support India’s energy transition goals.
