Gas Insulated Switchgear Market Size - By Capacity, By Voltage Level, By Application, Analysis, Share, & Forecast, 2025 - 2034

Gas Insulated Switchgear Market Size

The global gas insulated switchgear market was valued at USD 26.1 billion in 2024 and is estimated to reach the value of USD 55.8 billion by 2034, growing at a CAGR of 7.8% from 2025 to 2034. With the demand for electricity, urbanization, as well as power transmission and distribution systems steadily increasing, it is seeing consistent growth. The expansion of the market is witnessed in industrial, commercial, and utility sectors due to GIS outperforming traditional air-insulated switchgears in terms of space, dependability, and maintenance cost efficiency.
 

The expansion of renewable energy sources, such as wind and solar power, requires advanced grid infrastructure. According to recent data, the total global renewable energy capacity in 2024 is estimated to be around 3,864.52 GW as reported by the International Renewable Energy Agency (IRENA), with solar power being the leading driver of growth in the sector. GIS enables efficient energy transmission from renewable power plants to urban centers and industrial hubs while ensuring minimal power loss.
 

The escalating integration of urban infrastructure is one of the key factors responsible for the increase in demand for gas insulated switchgear (GIS), primarily noticed in megacities where space is both constrained and costly. While the world keeps shifting towards urban locations, governments and utilities are facing more challenges in ensuring a sustainable and constant power supply within the limited space. Unlike air insulated switchgear (AIS) which necessitates greater clearance gaps, additional land for insulation, as well as an extensive cubical structure to comply with the required distances, GIS is more suitable for use in Inhabited regions due to its compact modular design.
 

The regions are facing the climate concern due to rising carbon emission across the world. Total CO2 emissions in 2024 was projected to be 41.6 billion tons, up from 40.6 billion tons in 2023. Therefore, they are witnessing GIS adoption due to strict environmental regulations and a strong focus on reducing carbon emissions. The shift towards underground substations and smart grid deployment in countries like Germany, the UK, and France is also boosting gas insulated switchgear market expansion.
 

The world is moving towards industrialization and electrification, which is changing fundamental energy requirements, forcing utilities to update infrastructure to improve grid reliability and efficiency as well as resilience. This shift is more profound in emerging economies where the government is focusing on rural electrification, increasing industrial output, and establishing smart grids. As energy usage keeps climbing in the industrial, commercial, and domestic spheres, GIS is becoming a critical component for uninterrupted power supply and efficient energy distribution.
