Delectrik Systems Pvt. Ltd. has launched a multi-MWh scale vanadium flow battery (VRFB) energy storage system aimed at large commercial and industrial (C&I) customers and utility-scale applications, moving the Indian manufacturer beyond kilowatt-class units into the multi-megawatt-hour segment.
The announcement was dated 16 September 2024 and distributed via Cision on Newswire.ca. Its significance lies less in a single product launch than in the direction of travel: flow battery vendors are pushing up the size curve to compete for projects that were previously the preserve of lithium-ion containers.
Why multi-MWh matters
Vanadium flow batteries store energy in liquid electrolyte held in external tanks and circulate it through electrochemical stacks. Because capacity is set by electrolyte volume rather than by the number of cells, the technology scales economically with duration — the longer the discharge period required, the stronger the case relative to lithium-ion.
That makes multi-MWh systems the commercial proving ground. Large C&I sites and utilities buy in blocks of several megawatt-hours and expect multi-hour discharge, predictable degradation and low fire risk. Delectrik's positioning at that scale signals that the company now intends to bid for those blocks rather than only for smaller demonstration units.
Saudi Arabia and the localisation play
The scale-up has an international counterpart. Tdafoq Energy of Riyadh entered into a distribution and manufacturing licence agreement with Delectrik Systems of Gurgaon, India, for a GWh-scale vanadium flow battery energy storage project in Saudi Arabia, announced on 2 November 2022.
The deal combined distribution rights with local manufacturing licensing — an early indicator that Middle Eastern buyers want flow battery capacity built domestically rather than imported as finished systems.
That structure matters for the wider LDES market. Localisation agreements can accelerate deployment in markets with aggressive storage targets, but they also transfer manufacturing know-how and compress margins for the technology originator.
What to watch
The next test is conversion: whether multi-MWh product launches translate into firm orders, and whether GWh-scale licensing frameworks in the Gulf move from memoranda into installed capacity. For now, Delectrik's trajectory illustrates a broader shift in the flow battery sector — from laboratory and pilot-scale claims toward commercial product catalogues priced against lithium-ion.
