The project will be located at the 400kV Doni Substation of KPTCL, in Gadag district of Karnataka, the company stated in a regulatory filing. The project will be eligible for the state component for viability gap funding (VGF).
Prostram has secured the entire capacity at a rental of INR 2.54 lakh/MW/Month, i.e. yearly rental of INR 45.72 crore on 150 MW/300 MWh. The project will be developed on a build-own-operate (BOO) basis for 12 years.
“While the purchase order is still awaited, we are targeting to complete the installation within 12 months against an 18-month execution timeline. The estimated investment for the project will be approximately INR 300 crore,” Ram Agarwal, CEO, Prostarm Info Systems, told Energetica India.
In June 2025, the company received a letter of intent (LOI) from Bihar State Power Generation Company for setting up a 30 MW/120 MWh standalone Battery Energy Storage System in Bihar. The company secured the project under Tariff-Based Competitive Bidding (TBCB) mode at a tariff of INR 4.44 lakh/MW/month, amounting to a total annual rental of about INR 15.98 crore.
“As of now, PROSTARM’s total orders in hand and under pipeline stand at approximately 191 MW/442 MWh, with several more bids currently under evaluation. These projects collectively strengthen our renewable energy portfolio and reaffirm our commitment to contributing meaningfully to India’s clean energy transition,” shared Agarwal.
According to him, Battery Energy Storage Systems (BESS) are fundamentally different from solar EPC or other renewable projects. “They require specialised expertise, strong technical execution, and above all, a robust service capability. Success in this domain depends on having a clear and effective risk mitigation plan, which remains at the core of PROSTARM’s strategy,” he said.
Agarwal further added, “Looking at the current and evolving market potential, PROSTARM is strategically preparing to scale its renewable energy portfolio by expanding into significant business opportunities across both OPEX and EPC models in FY 2026–27.”
In July 2025, the company announced its plans to set up a 1.2 GWh Battery Energy Storage System (BESS) manufacturing facility at Reliance MET City in Haryana, with a planned investment of INR 25 crore. The plant is expected to be commissioned by the end of FY26.
