Urbanization and Space Optimization Needs
Rapid urbanization and the need for compact power systems drive GIS adoption across cities and industrial areas. Unlike air-insulated systems, GIS requires minimal installation space, making it ideal for underground or high-density environments. Urban infrastructure projects, metro networks, and industrial complexes rely on GIS for uninterrupted operations. Its modular design, high safety, and reduced maintenance needs make it an efficient choice for sustainable power distribution in growing metropolitan regions.
Key Trends & Opportunities
Adoption of Digital and Eco-Friendly Switchgear
The market is witnessing a clear shift toward digital and eco-friendly gas insulated switchgear. Manufacturers are adopting sensors, IoT, and cloud-based monitoring to improve predictive maintenance and system efficiency. The use of SF6-free gases, such as dry air and fluoronitrile blends, is gaining traction to lower greenhouse gas emissions. These innovations align with global sustainability goals and open opportunities for manufacturers to expand portfolios with environmentally responsible GIS solutions.
- For instance, Schneider Electric’s RM AirSeT is an SF₆-free ring-main GIS rated up to 24 kV for secondary distribution with integrated digital features.
Rising Investments in Transmission Network Modernization
Modernization of existing transmission networks presents significant opportunities for the GIS market. Governments across Asia-Pacific, Europe, and the Middle East are upgrading old substations with advanced switchgear to handle increasing power demand. GIS offers improved reliability, reduced outages, and enhanced safety in densely populated or environmentally sensitive zones. Such modernization projects will continue to create strong business prospects for GIS suppliers worldwide.
- For instance, Mitsubishi Electric developed and tested 1,000 kV GIS equipment at TEPCO’s Shin-Haruna UHV station, advancing ultra-high-voltage upgrade programs.
Key Challenges
High Installation and Maintenance Costs
The high cost of installation and maintenance remains a major challenge in the gas insulated AC switchgear market. GIS systems involve complex engineering and expensive materials, making them costlier than conventional air-insulated options. The initial investment limits adoption in developing countries with budget constraints. Additionally, specialized maintenance and limited availability of skilled technicians increase operational expenses, affecting deployment in smaller or low-voltage applications.
Environmental Concerns Over SF6 Gas Usage
Environmental concerns linked to sulfur hexafluoride (SF6) usage pose a serious challenge. SF6 is a potent greenhouse gas with high global warming potential, leading to regulatory pressure on manufacturers to find alternatives. While research into eco-friendly substitutes is ongoing, the transition adds cost and complexity. Compliance with environmental norms and the need for leak detection systems further increase operational challenges for utilities and manufacturers relying on SF6-based GIS systems.
