North America Gas Insulated Switchgear Market: Market Size & Forecast 2026

The North American Gas Insulated Switchgear (GIS) market encompasses equipment rated from medium voltage up to ultra-high voltage, primarily used in power transmission and distribution substations, industrial facilities, and urban utility networks. Valued at approximately $5.8 billion in the base year of 2025, the market is on track to reach around $6.18 billion in 2026, with a projected CAGR of greater than 6% through the forecast horizon. GIS represents a specialized and higher-value segment within the broader North American switchgear market, which is estimated to reach nearly $19.2 billion by 2031.

• •Market valued at ~$5.8 billion in 2025, rising to ~$6.18 billion in 2026 with a 6.5% CAGR
• •North America GIS is part of a broader switchgear market projected at ~$19.2 billion by 2031
• •Global GIS market reached ~$28.56 billion in 2025 and is projected to reach ~$56 billion by 2035

The primary growth engine for the North American GIS market is the ongoing replacement and modernization of aging power infrastructure, with utilities and grid operators upgrading legacy systems to improve reliability and capacity. Federal and regional grid modernization initiatives, combined with the electrification of transportation and increased electricity demand, are driving investments in compact, high-reliability substation equipment. The growing share of renewable generation, including wind and solar, is also creating demand for GIS as utilities build new transmission corridors and interconnection points.

• •Aging grid infrastructure replacement and grid modernization programs across the US and Canada
• •Electrification trends and rising electricity demand requiring expanded transmission capacity
• •Renewable energy integration creating new substation build-out and interconnection requirements

The North American GIS market is segmented by voltage class, with primary (high-voltage, above 72.5 kV) and secondary (medium-voltage, up to 72.5 kV) GIS representing the two dominant product categories. Geographically, the United States holds the largest share driven by extensive utility-scale investments and federal infrastructure funding, while Canada contributes steadily through utility and industrial applications, and Mexico shows emerging growth tied to its expanding power sector. Urban and industrial applications account for a significant portion of demand, given GIS's compact footprint advantage in space-constrained environments.

• •High-voltage primary GIS dominates revenue share, while medium-voltage secondary GIS sees strong adoption in urban and commercial projects
• •The United States leads the regional market, supported by utility capital expenditure programs and federal infrastructure investment
• •Canada and Mexico represent smaller but growing sub-markets driven by utility grid expansion and industrial sector demand

Who are the notable companies in the industry?

The North American GIS market exhibits a moderately consolidated structure, with a tiered competitive landscape comprising large diversified electrical equipment manufacturers alongside specialized producers focused on gas-insulated technology. The technology and process routes in the market are centered on SF6-gas-encapsulated, hermetically sealed designs, though environmental regulations around SF6 emissions are gradually encouraging the development of alternative gas mixtures and vacuum-based solutions. Production capacity is concentrated in major industrial hubs across the United States, with additional manufacturing presence in Canada and Mexico serving both domestic demand and export markets.

• •Market structure is moderately consolidated, combining large integrated electrical equipment producers with smaller specialty manufacturers
• •Core technology relies on SF6-gas-sealed medium- and high-voltage designs, with emerging alternatives such as fluoronitrile-based and vacuum GIS gaining regulatory support
• •Manufacturing and assembly capacity is largely concentrated in the United States, complemented by production facilities in Canada and Mexico

What are the recent trends and outlook?

Looking ahead, the North American GIS market is expected to maintain steady growth momentum as grid operators prioritize resilience, digital substation automation, and compliance with evolving environmental standards. The transition toward eco-friendly insulating gases, driven by SF6's high global warming potential, is a notable technology trend shaping future product development and procurement specifications. Additionally, increasing demand for substation compactness in dense urban environments and the growth of data center infrastructure are expected to sustain above-average demand for GIS solutions throughout the forecast period.

• •Rising adoption of eco-friendly gas alternatives to SF6 as environmental regulations tighten globally
• •Digital substation automation and smart grid integration driving upgrades to existing and new GIS installations
• •Sustained urban development and data center expansion fueling demand for space-efficient, high-reliability switchgear
