Bondada Bags NTPC REL Order For 100 MWh Battery Storage

24 Jul 2026 CW Team

The project is designed to support the integration of renewable generation into the national grid by providing long-duration storage capacity. VRFB technology offers several advantages over conventional lithium iron phosphate battery systems, including extended cycle life and the ability to scale energy and power independently. The use of vanadium electrolyte reduces degradation mechanisms common to particulate electrode chemistries and supports stable performance over prolonged duty cycles.

Bondada said the technology aligns with India’s vision of strengthening energy security by reducing long-term dependence on imported cells through the utilisation of domestic vanadium resources or import from diverse sources. The NTPC REL order includes 10 years of operations and maintenance to support commissioning and early operational performance. The extended service package is intended to ensure system availability and to facilitate knowledge transfer during initial deployment.

The deployment at Khavda Solar Park represents a step towards broader adoption of long-duration storage technologies within the renewable sector and supports efforts to balance intermittent generation with dispatchable capacity. The partnership between Bondada and Delectrik is positioned to build domestic competence in flow battery deployment and to support grid stability as renewable capacity expands. Over time, the project is intended to contribute to diversification of supply chains for critical battery materials and to strengthen domestic manufacturing capability.

Bondada Engineering has secured an engineering, procurement and construction (EPC) package from NTPC Renewable Energy for the development of a 100 MWh Vanadium redox flow battery energy storage system (VRFB BESS) at Khavda Solar Park in Gujarat, with Delectrik Systems as the technology partner. The EPC award covers delivery of the battery system, site integration and associated balance of plant work necessary to connect the installation to the solar park. Bondada will manage project execution and coordination with NTPC REL and other stakeholders.
