Utilities are upgrading transmission and distribution switchgear networks to accommodate changing load patterns, new generation sources, and rising electricity consumption. Aging switchgear also needs to be inspected, replaced, or modernized to maintain network reliability and meet current operating requirements. In April 2025, the NC Clean Energy Technology Center reported 362 grid modernization actions in Q1 2025 in 47 U.S. states, Washington, D.C., and Puerto Rico. Most activity focused on energy storage, interconnection rules, and smart grid deployment (Source: nccleantech.ncsu.edu).

Circuit breakers, protection systems, busbars, monitoring equipment, and coordinated switching assemblies are replaced or upgraded in substation modernization. Medium voltage switchgear is used in distribution networks and industrial power systems, and high-voltage switchgear is used in transmission infrastructure and major substations. The selection of equipment depends upon fault levels, operating voltage, conditions of installation and maintenance. These factors tie demand for switchgear to capital spending by utilities and to long-term electricity infrastructure planning.

Driver: Expanding AI Data Centers and High-Density Power Distribution

AI and hyperscale data centers are expanding, propelling the demand for reliable electrical infrastructure. High-density computing needs a constant power supply for servers, networking gear, and data center cooling systems. Low voltage switchgear is used to distribute power to downstream equipment. Medium voltage switchgear may be used for incoming utility supplies and internal distribution systems, depending on the facility design.

Data center operators consider redundancy, protection coordination, fault clearing performance, and maintenance access when specifying equipment. Arc-resistant switchgear and remote operation features can enhance personnel safety and maintenance planning. Power distribution designs also must provide for future capacity, backup generation, and uninterruptible power systems. The growing AI data center market and hyperscale data center market create an important demand area for switchgear manufacturers.

Driver: Renewable Energy and Storage Integration

Switching and protection equipment are required at generation sites, collection networks, and grid interconnection points for solar, onshore wind, and offshore wind projects. Large renewable installations may require medium voltage equipment for collection systems and high voltage equipment for grid connection. Offshore wind projects often require small equipment for tight spaces and harsh operating conditions. IEA expects global renewable power capacity to grow by 4,600 GW by 2030, with solar PV providing almost 80% of the growth (Source: IEA).

Further switching requirements are added by battery energy storage systems (BESS) and microgrids. BESS switchgear isolates circuits, protects against faults and coordinates storage equipment, inverters and connected networks. Microgrid switchgear is used to control electrical connections between distributed generation, storage, and the main utility supply. Additional demand opportunities are created by growth in the renewable energy market and the battery energy storage system market.

Restraint: High Equipment Costs and Long Lead Times

It introduces staged limits on some new switchgear that uses fluorinated greenhouse gases. Demand will be subject to equipment availability, voltage ratings, qualification requirements, and project-specific technical requirements. Investment in grid in emerging economies outside China has fallen 7% annually, while 2,500 GW of renewable and storage projects are waiting to be connected to the grid globally. Some 750 million people still have no access to electricity (Source: UNCTAD).

Manufacturers can open up new market opportunities by developing SF₆-free solutions for medium and high voltage applications, thereby strengthening their product portfolios and supporting utilities in equipment replacement and substation modernization. Buyers will compare environmental performance against reliability, footprint, maintenance and switchgear total cost of ownership. The regulatory change could also open up opportunities for suppliers of engineering support and equipment for future compliance. Applicable requirements and exceptions should be checked against the official EU Regulation 2024/573.

SF₆ Phase-Out and F-Gas Regulation

An important technology and procurement consideration in the switchgear market is the transition away from sulfur hexafluoride (SF₆). SF₆ is an excellent insulating and arc-quenching gas, but its high global-warming potential raises environmental concerns in case of leakage. Depending on the voltage, the application and the design of the equipment, SF₆-free switchgear alternatives use different insulation media or gas mixtures.

EU Regulation 2024/573: Timeline by Voltage Class

EU Regulation 2024/573 sets phased restrictions on putting specified new fluorinated-gas switchgear into operation. The exact application depends on voltage class, short-circuit rating and the regulation’s exceptions. Procurement teams should think about the relevant equipment category and compliance date when specifying new installations. The regulation also covers SF₆ servicing after 2035 with certain conditions for reclaimed or recycled gas.
