SPML Infra’s BESS battery pack completes key global certification & testing requirements
- September 4, 2026
SPML Infra Ltd has announced a significant milestone in its BESS journey, with its proprietary 104.4 kWh battery pack successfully completing key international safety, performance and transportation certification and testing requirements.
In a release, SPML Infra said that battery pack has been engineered and developed as part of SPML’s strategy to build indigenous technology and manufacturing capabilities for India’s rapidly expanding grid-scale energy storage market.
The SPML-developed 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.
Together, these compliances address critical areas including thermal runaway safety, battery performance, system functional safety, electromagnetic compatibility and transportation safety.
Indigenous BESS technology
A key element of this milestone is the development of the 104.4 kWh battery pack under SPML’s own intellectual property. 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.
Important validation
Abhinandan Sethi, Managing Director, SPML Infra Ltd, said: “The validation of our proprietary 104.4 kWh battery pack represents an important milestone in SPML Infra’s energy storage journey. What makes this particularly significant for us is that we are developing technology and engineering capabilities within SPML, rather than limiting our role to manufacturing or project execution. Completion of these international certification and testing requirements provides important validation of the safety and engineering foundations of our product. Our ambition is to build an integrated Indian energy storage platform spanning proprietary product development, manufacturing, system integration and large-scale project execution. We believe this combination can create significant long-term value as energy storage becomes an increasingly critical component of India’s power infrastructure.”
Towards commercial deployment
SPML Infra sees BESS as a strategic extension of its established capabilities in power infrastructure and an important pillar of the company’s future growth. The successful completion of certification and testing requirements for its proprietary 104.4 kWh battery pack marks another important step towards commercialization of SPML’s BESS technology and manufacturing platform. The company will continue to develop and expand its energy storage technology portfolio as it builds capabilities to address the evolving requirements of India’s utility-scale BESS market, the release added.
