Delectrik Systems Pvt Ltd, a leading player in the battery energy storage space, has won a significant tender from NTPC’s NETRA (NTPC Energy Technology Research Alliance) division to deploy a 3 MWh Vanadium Redox Flow Battery (VRFB)-based Battery Energy Storage System (BESS). This long-duration energy storage (LDES) solution will support NETRA’s microgrid, offering complete autonomy for up to one day and paving the way for self-sufficiency in its power requirements.
The installation will take place at NTPC’s NETRA campus in Greater Noida in the first half of 2025. Delectrik’s cutting-edge VRFB technology will form the backbone of this system, based on its newly launched large-scale product architecture designed for Commercial, Industrial, and Utility-scale applications.
NTPC, India’s largest power utility with an installed capacity exceeding 76 GW, is progressively moving towards renewable energy, targeting 130 GW by 2032. Of this, 60 GW will come from renewable sources, aligning with the country’s broader goals of sustainability and reducing emissions.
Collaborating with Rays Power Infra, one of India’s prominent EPC companies, Delectrik secured this contract to accelerate large-scale VRFB deployments in India. Rays Power Infra, with over 1.5 GWp of solar projects commissioned across India and Southeast Asia, brings a wealth of experience in renewable energy projects.
India’s demand for energy storage solutions is rapidly increasing, particularly as it targets sustainable energy goals. According to the National Electricity Plan (NEP 2023), the domestic requirement for stationary BESS systems is expected to reach 411 GWh by 2031-32. At present, India’s total BESS deployment stands at less than 1 GWh, highlighting the massive potential for growth in the sector.
Dr Vishal Mittal, Founder & CEO of Delectrik Systems, expressed his enthusiasm about the milestone. “This MWh-scale tender and award represent a strong vote of confidence from NTPC in Delectrik’s Flow Battery-based BESS and its potential to meet future grid-scale requirements in India. This project will kickstart large-scale Flow Battery deployments across the country.”
Dr Mittal emphasised the cost-efficiency and scalability of flow battery technology. “In addition to low product costs, the capital investment required to manufacture GWh-scale Flow Batteries is 10 to 20 times lower compared to lithium-ion batteries. This is crucial as India aims to ramp up its BESS manufacturing capacity to over 100 GWh.”
He further highlighted that for large installations, flow batteries offer a per-acre capacity of up to 200 MWh, which is less than 1% of the area required for equivalent photovoltaic (PV) installations. “The long life, low cost, and sustainability of Flow Batteries make them ideal for pairing with renewables like PV and wind, offering round-the-clock clean, affordable energy. This project will significantly contribute to India’s Net Zero emissions target,” Dr Mittal added.
The Delectrik-NTPC collaboration marks a major advancement in India’s renewable energy journey, positioning flow battery technology as a key enabler of long-duration energy storage and sustainable power generation.
