Indian Transmission Sector to See Innovative Switching Technologies from iSAT India

As part of the agreement, CoelmeEgic — part of Southern States Investment Holdings (SSIH, USA) — has acquired a minority equity stake in iSAT India and will join its Board, marking a long-term commitment to India’s rapidly expanding Transmission, Distribution, and Railway infrastructure markets.

The joint venture will localize the manufacturing of advanced high-voltage switching systems in India, with an initial focus on:

• Disconnectors up to 800 kV

• Railway Catenary OHE switches

• Specialized high-voltage switching devices

To support this initiative, iSAT is expanding its Haridwar facility with a new 30,000 sq. ft. manufacturing unit, scheduled to be operational in 2026. This expansion positions India not only as a domestic manufacturing base but as a strategic supply hub for global markets within the Southern States and CoelmeEgic group.

Founded in 1998, iSAT India has built a strong reputation in EPC services for Transmission & Distribution projects and in designing high-power testing laboratories, including 1500 MVA online short-circuit facilities for national institutions. The company also designs and manufactures specialized switching devices and holds multiple patents.

COELME (Italy) and EGIC (France), operating as a unified European industrial group, bring decades of expertise in high-voltage equipment ranging from 17 kV to 800 kV, with a strong installed base across European transmission grids, HVDC systems, and railway operators.

Southern States, founded in 1916 in Hampton, Georgia, is a global leader in high-voltage disconnect switches and grid resilience technologies, with advanced protection systems and a robust portfolio of patented solutions.

Sudhanshoo Agarwal, CEO & MD, iSAT India, said, “This collaboration aligns strongly with the Government of India’s Make in India and Aatmanirbhar Bharat initiatives. By localising advanced 800 kV switching technologies, we aim to strengthen India’s grid resilience, support railway electrification, and contribute meaningfully to global supply chains.”

Francesco Basso, Chairman, CoelmeEgic, added, “India’s transmission and railway infrastructure are expanding at remarkable speed. In iSAT, we have found a capable and technology-driven partner. We are committed to bringing proven Italian and French engineering expertise to India through long-term industrial cooperation.”

Raj Anand, Chairman, Southern States, commented, “As an IIT Delhi graduate, contributing to India’s infrastructure development has always been close to my heart. This joint venture reflects our confidence in India’s growth trajectory and engineering talent.”

The partnership supports:

• Localization of ultra-high voltage equipment up to 800 kV

• Reduced dependency on imports

• Technology transfer and engineering skill development

• Strengthening of India’s transmission and railway electrification infrastructure

• Integration with global supply chains

With India investing heavily in grid expansion, renewable integration, and railway electrification, the joint venture is positioned to serve both domestic demand and international markets.
