Air insulated switchgear market was valued at $52.30 billion in 2025 and is projected to reach $83.37 billion by 2035, growing at a CAGR of 4.8% during the forecast period (2026-2035). The market is expanding at a fast pace owing to the increasing global electricity demand and grid modernization investments, government regulation, expansion of renewable energy capacity, surge in data centers, and rapid urban electrification efforts in emerging economies. According to the International Energy Agency (IEA), Global electricity demand grew by 4.3% in 2024, driven by industrial electrification, digital infrastructure, and electric mobility expansion. This surge in power consumption is stimulating the demand for efficient and reliable medium-voltage distribution systems, where air insulated switchgear plays a vital role in ensuring safety and operational continuity.

Rising Grid Modernization and Utility Investments Driving Demand for Air-Insulated Switchgear
Reliable power supply, utilities, and transmission operators are investing in substation modernization and grid extensions. For instance, the US Department of Energy (DOE) allocated $10.5 billion under the Grid Resilience and Innovation Partnerships (GRIP) Program. These initiatives boost demand for air insulated switchgear, which is essential for medium-voltage substations. Moreover, in July 2025, National Grid introduced a transformative new approach to the way it works with Britain’s supply chain, designed to accelerate the delivery of $10.8 billion worth of vital substation infrastructure across England and Wales and support the UK’s clean energy transition. Such programs directly enhance the need for air insulated switchgear, which plays a critical role in controlling medium-voltage substations. Utilities replace outdated infrastructure and expand networks to integrate renewable energy. This also accelerates the adoption air insulated switchgear across urban and remote installations.
Growing Adoption of Modular and Flexible Air-Insulated Switchgear Systems Enhancing Operational Continuity
Air-insulated switchgear offers a modular and flexible design that simplifies installation, use, and maintenance. It offers LSC2B/LSC2A/LSC2/LSC1, ensuring minimal service interruption and a high level of customization to meet global demanding requirements, and can be typically found in all industries. Companies such as ABB offer UniGear ZS1, a medium-voltage air-insulated switchgear system designed to meet the IEC 62271-200 standards with LSC2B classification, ensuring maximum service continuity and operator safety. The product is modular in construction, allowing easy configuration of panels for different voltage levels (up to 24 kV), current ratings, and feeder types (incomer, bus coupler, metering, or outgoing).
Market Segmentation
Circuit breakers Segment Driving Growth in the Air Insulated Switchgear Market
Circuit breakers account for the largest share in the market due to their critical role in protection, control, and fault management across medium- and high-voltage systems. Government-backed infrastructure programs and renewable grid expansion projects have significantly increased the deployment of circuit breakers, which are essential for ensuring system reliability, safety, and automatic fault isolation in substations and industrial networks. According to the Ministry of New and Renewable Energy (MNRE), India’s grid is being reimagined through the ?2.4 lakh crore Transmission Plan for 500 GW, linking renewable-rich states with demand centres. The Government is prioritizing investment in transmission infrastructure through the Green Energy Corridors and new high-capacity transmission lines from Rajasthan, Gujarat, and Ladakh. While these projects are multi-year efforts.
Rising Data Center Electricity Demand Accelerates Adoption of Air-Insulated Switchgear
The US Department of Energy (DOE), that data centers consumed about 4.4% of total US electricity in 2023 and are expected to consume approximately 6.7% to 12% of total US electricity by 2028. Moreover, the International Energy Agency (IEA) from 2024 to 2030, data centre electricity consumption grows by around 15% per year, more than four times faster than the growth of total electricity consumption from all other sectors. The sharp rise in data center electricity consumption drives demand for air insulated switchgear. The expansion of hyperscale and edge data centers creates the demand for modular, LSC2B-classified air insulated switchgear panels to manage heavy loads with minimal downtime.
