SPML Infra Limited (NSE: SPMLINFRA, BSE: 500402), a leading publicly listed infrastructure development company in India, has achieved a major milestone in its Battery Energy Storage System (BESS) journey. The company’s proprietary 104.4 kWh battery pack, developed using SPML’s own intellectual property, has successfully completed key international certification and testing requirements covering safety, performance and transportation.
The 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.
Building Indigenous BESS Technology and Manufacturing
A key element of this milestone is the development of the 104.4 kWh battery pack under SPML’s
own intellectual property, strengthening 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.
Abhinandan Sethi, Managing Director, SPML Infra Limited, 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.”
Advancing Towards Commercial Deployment
India’s accelerating renewable energy deployment is creating significant demand for energy
storage solutions capable of supporting renewable integration, grid balancing, peak-load
management and overall grid reliability. 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.
