Gas Insulated Switchgear (GIS) Systems: The Smart Investment for Efficient and Resilient Energy Distribution

Highlights

• Introduction
• Applicability of GIS
• Growth of the Asia-Pacific GIS industry
• Recent developments in the landscape

The growing global demand for electricity has driven the development of advanced technologies aimed at improving the performance and reliability of electrical grids. One such innovation is gas insulated switchgear (GIS) which significantly transforms power system operations. GIS is a high-voltage terminal that uses gas, typically sulfur hexafluoride (SF6), for insulation and arc extinction. Unlike traditional air-insulated switchgear, GIS features a compact, enclosed design that ensures efficient space utilization and enhanced safety.

GIS requires significantly less space than conventional switchgear, making it ideal for densely populated urban areas. The gas insulation in GIS enhances the safety of both personnel and the public by minimizing the risk of arc flashes. Additionally, with its sealed enclosures and robust design, these systems offer high reliability and low maintenance requirements. 

Advanced GIS systems involve compact gas-insulated, integrated three-phase, and hybrid switchgears. Industries need robust electrical systems capable of withstanding harsh conditions. GIS is utilized in industrial townships and complexes, offering reliable service with minimal maintenance needs due to its sealed nature. The gas-insulated switchgear (GIS) industry is estimated to cite a notable CAGR of 4.3% by 2032.

Revolutionizing renewable energy integration and grid efficiency

GIS systems are designed to operate with minimal maintenance due to their sealed construction and the use of high-quality insulating gases like SF6 in newer models. This results in lower operational costs and reduced downtime, ensuring that energy distribution systems remain operational and efficient throughout their long service life. The robust design of GIS protects against environmental factors such as dust, moisture, and corrosive elements, which cause equipment failure in traditional systems. This reliability minimizes the possibility of outages and energy losses due to equipment failures, thereby enhancing power utility.

GIS is essential for integrating renewable energy sources, such as wind and solar power, into the grid. Its compact design and ability to operate in harsh conditions make it well-suited for offshore wind farms and solar installations. This facilitates the efficient transmission of renewable energy and helps reduce reliance on fossil fuels. While the initial investment in GIS is higher than that for traditional systems, the long-term savings from reduced maintenance, lower operational costs, and minimized energy losses result in bringing down the total expenses. This ultimately makes GIS a cost-effective solution for energy distribution.

Examining the evolving landscape of the Asia-Pacific GIS industry

Rapid urbanization in Asia-Pacific countries is fueling the need for more reliable and efficient electrical distribution systems. There is a growing demand for advanced switchgear solutions capable of operating in confined spaces. The region is increasingly integrating renewable energy sources into its power grids. This shift is highlighted by the need to meet energy demands sustainably, with renewables accounting for a significant share of electricity generation capacity in countries like China. GIS technology is essential for managing the complexities of renewable energy integration. 

Siemens increased its production capacity for switchgear

Siemens is investing $100 million to enhance its switchgear manufacturing facility in Frankfurt, Germany. The company has recently opened a new highly advanced warehouse and expanded the production area, with operations anticipated to commence in early 2025. 

The expansion enables Siemens to boost the production capacity of its SF6-free blue GIS medium-voltage switchgear, 8DAB. This switchgear, used in transformers and switching stations, utilizes the climate-neutral Clean Air insulating medium made from natural constituents of the surrounding air. Siemens has emphasized its commitment to transitioning from SF6 and focusing on sustainable medium-voltage switchgear solutions.

ABB India’s new factory to double its production capacity for GIS

In February 2023, ABB India inaugurated a new factory in Nashik, doubling its production capacity for gas insulated switchgears. This facility manufactures primary and secondary GIS, catering to customers across various industries such as power distribution, smart cities, data centers, transport (including metro and railways), tunnels, ports, highways, and other infrastructural developments.

The factory uses advanced robotics for manufacturing, connecting people, processes, and assets, and is capable of relaying real-time data to enhance productivity. This green building, developed in line with the Indian Green Building Council (IGBC) norms, optimizes the use of both water and energy. Additionally, the factory uses specialized materials to minimize the environmental impact over its life cycle.

To conclude, gas insulated switchgear (GIS) systems revolutionize energy distribution with compact design, reliability, and low maintenance needs, making them ideal for urban areas and harsh environments. Additionally, they support efficient power transmission and are essential for integrating renewables into conventional electricity grids. Moreover, rapid urbanization, growing adoption of renewable energy, and major investments highlight the industry's shift toward sustainable and efficient technologies.
