SPML Infra Limited has achieved a significant milestone in its energy storage journey, with its proprietary 104.4 kWh Battery Energy Storage System (BESS) battery pack successfully completing key international certification and testing requirements.

Certification milestone for BESS battery pack

The company developed the battery pack under its own intellectual property, marking a notable development in SPML Infra's strategy to build indigenous technology and manufacturing capabilities. The achievement covers the 104.4 KWH BESS battery pack, validating its safety and engineering foundations for commercial deployment.

The battery pack has successfully completed requirements under UL9540A, IEC 62619, IEC 63056, IEC 60730, IEC 61000-6-2 and IEC 61000-6-4, together with UN38.3 at the battery-pack and system level. These compliances address critical areas including thermal runaway safety, battery performance, system functional safety, electromagnetic compatibility and transportation safety.

Building indigenous BESS technology

A key element of this milestone is the development of the battery pack under SPML's own intellectual property. This strengthens the Company's ability to develop, manufacture and further evolve battery energy storage products for the Indian market. SPML Infra is establishing its BESS manufacturing and integration capabilities in Pune, Maharashtra, with capabilities being developed across battery pack assembly, engineering, system integration and large-scale project execution.

The milestone represents an important step in SPML's strategy to progressively localize critical BESS engineering and technology capabilities in India, while building greater control over product development and evolution. The Company believes that combining proprietary product engineering with domestic manufacturing and its established EPC execution capabilities can create a differentiated platform for participation in India's emerging energy storage ecosystem.
