Urban infrastructure in India is witnessing growing investment driven by urbanization, increasing focus on energy efficiency and public infrastructure development. As cities increasingly adopt technology-enabled street lighting systems that improve energy efficiency, monitoring and asset management, demand is rising for service providers capable of delivering both installation expertise and long-term operations and maintenance of lighting infrastructure. Citelum India operates in this segment offering services across the design, engineering, installation and maintenance of street lighting and city lighting infrastructure with extensive experience in delivering connected lighting solutions and managing lighting assets. The proposed acquisition will enable Krystal to integrate Citelum India’s technical capabilities with its existing operational strengths in integrated services and technical maintenance enhancing its ability to participate in infrastructure-linked opportunities requiring specialized engineering expertise and long-term service delivery. Citelum India will operate as a wholly owned subsidiary of Krystal Integrated Services Limited, supporting the Company’s strategy of expanding into adjacent infrastructure service verticals and strengthening its positioning in city lighting and urban infrastructure services. Commenting on the performance, Mr. B Sivakumar, CEO & Director, Citelum India Private Limited, said, “The acquisition by Krystal Integrated Services Limited marks an important milestone in Citelum India's growth journey.
