Reliance Power’s subsidiary--Reliance NU Energies has won the largest allocation in SJVN’s tariff-based competitive bidding process, securing an allocation of 350 MW of solar generation capacity coupled with 175 MW/700 MWh of battery energy storage system (BESS).

Once commissioned, the platform will add 600 MWp of installed solar PV capacity, and 700 MWh of energy storage to Reliance Power’s portfolio, consolidating its leadership in new energy solutions. The company’s total clean energy pipeline now stands at 2.5 GWp solar and >2.5 GWhr BESS, making it India’s largest player in the integrated Solar + BESS segment.
