What happened

A localised fire broke out at ACME Solar Holdings' Suryodaya Battery Energy Storage System facility in Pokhran, India. The fire affected four Power Conversion System (PCS) units and was extinguished by the site's in-house fire safety team following established protocols. The company confirmed that none of the battery energy storage containers were damaged, and the incident was limited to the PCS equipment. ACME estimated the financial impact at around Rs 20 lakh, describing it as not material to the business.

Restoration work began soon after the fire using spare equipment, with the damaged systems expected to return to service within about a week. The company issued a public statement confirming the cause as an IGBT-related short circuit within the affected PCS units.

Contributing factors

The company attributed the fire to an IGBT-related short circuit within the power conversion equipment.

Lessons learned

Physical separation of PCS units from battery containers limits fire spread to equipment only.
In-house teams trained on protocols can control localised fires at BESS sites quickly.
Spare PCS units kept on site allow fast replacement after short-circuit faults.
