Gurgaon-based Delectrik Systems, an energy storage technology company, has been awarded a contract by NTPC for its NTPC Energy Technology Research Alliance (NETRA division) to implement a 3 MWh Vanadium Redox Flow Battery (VRFB) based Battery Energy Storage System (BESS).

This VRFB system will serve as a long-duration energy storage (LDES) solution, enhancing NETRA’s microgrid capacity to achieve full autonomy for an entire day, moving it  closer to energy self-sufficiency.

The installation will utilize Delectrik’s newly introduced large-scale product architecture, designed for significant commercial, industrial, and utility applications.

This system is set to be deployed at the NETRA campus in Greater Noida in the first half of 2025.

Delectrik secured the tender in partnership with Rays Power Infra, an EPC company that has commissioned over 1.5 GW of solar projects across India and Southeast Asia.

The company said the flow batteries can provide up to 12 hours of continuous power supply, with their modular design allowing for easy scaling from kWh to GWh capacity.

With a lifespan of over 20 years, these batteries offer a durable energy storage solution. The aqueous electrolyte used in VRFBs is non-flammable, enhancing overall safety.

Flow batteries are expected to play a crucial role in addressing the intermittency challenges associated with solar and wind power generation.

NTPC invited bids for the supply, installation, commissioning, and integration of a 600 kW/3000 kWh Vanadium Redox Flow Battery (VRFB) storage system at the NTPC Energy Technology Research Alliance (NETRA) facility in Greater Noida.

Recently, NTPC Vidyut Vyapar Nigam (NVVN) also floated a tender for setting up 500 MW/1000 MWh standalone battery energy storage systems (BESS) with Viability Gap Funding (VGF) support.
