Indexel Engineering, a family-owned EPC firm based in Rajasthan, has teamed up with US-based battery innovator Unigrid to bring 50 MWh of advanced sodium-ion battery storage to India.
The Unigrid battery systems will be deployed across industrial hubs, renewable integration projects, and microgrid applications. The first installations will begin in the second half of 2025, with a focus on Rajasthan, Gujarat, Maharashtra and other western states.
“We’re thrilled to have Unigrid as our technology partner,” said Anushka Singhal, Energy Division Lead at Indexel, IONS. “Sodium-ion batteries are safer, cheaper, and better suited for our climatic conditions.”
Unlike lithium-ion, sodium-ion batteries are non-flammable, operate reliably at temperatures between -40°C to 60°C, and utilize abundant raw materials, making them a safer, more cost-effective, and sustainable solution for India’s energy storage needs.
“India is one of the world’s most dynamic energy markets and offers many opportunities for new energy technology adoption. We are excited to partner with Indexel Engineering to expand the reach of our sodium-ion technology in this impressive and innovative region,” said Darren H. S. Tan, co-founder and CEO of Unigrid.
