L-R: POWERGRID team including Anuj Bhutani, DGM – Engineering-Substation; Rajil Srivastava, ED – Asset Management; Vamsi Rama Mohan Burra, Director – Projects; Abhay Kumar, CGM-I/C Engineering; and Nunavath Ravi, CM-QA&I flagging off India’s First m-GIS developed by Toshiba & POWERGRID.
Power Grid Corporation of India (POWERGRID) and Toshiba have launched the country’s first indigenously manufactured 220kV Mobile GIS (m-GIS) system. Toshiba Transmission & Distribution Systems (India) Private Limited (TTDI) has delivered the system to POWERGRID.
The 220kV m-GIS System is designed and built fully in line with POWERGRID’s operational requirements, a statement said here on Thursday.
Gas-Insulated Switchgear (GIS) is a compact and highly reliable system used for safe and efficient high-voltage power distribution, especially in space-constrained environments. “Recognising the need for mobility and rapid response, POWERGRID played a key role in conceptualising the technical contours of an m-GIS solution. The system offers rapid deployment and enhances grid flexibility, resilience, and disaster-readiness,” it said.
“Its modular ‘connect–disconnect–redeploy’ feature ensures operational agility, making it a game-changer for handling emergency and flexible grid needs,” it said.
TTDI said it would produce the country’s first indigenous 400kV m-GIS system for POWERGRID, which is expected to be delivered in August next.
