Editorial readout 
The strongest GIS statistics point to one conclusion: demand is being shaped by grid upgrades, renewable connection, urban land pressure, high-voltage transmission, and lower-emission equipment planning. 

Why GIS Market Growth Now Carries Grid-Scale Importance 

Gas insulated switchgear demand rises when power networks become more complex. A utility that needs to connect renewable generation, reinforce a dense city grid, replace aging substations, or support high-load industrial customers often has to solve for reliability and space at the same time. GIS is valuable because it places high-voltage switching equipment inside a compact gas-insulated enclosure, reducing footprint compared with traditional air-insulated designs. 

That market context matters because electrical infrastructure is entering a multi-year upgrade cycle. Electricity demand is rising again in advanced economies, industrial electricity use is growing, transport electrification is accelerating, and data centers are becoming large grid customers. At the same time, solar, wind, and offshore wind projects require interconnection infrastructure, and transmission bottlenecks are forcing grid operators to plan higher-capacity substations and stronger networks. 

Market-growth and grid-demand benchmarks 

• Around USD 310 billion was invested in power grid infrastructure globally in 2023. 

• Global investment in power grid infrastructure increased by 5.3% in 2023. 

• Around USD 400 billion is spent on grids worldwide each year, compared with about USD 1 trillion spent on generation assets. 

• Current annual grid investment is therefore about 40% of annual generation-asset investment globally. 

• The United States accounted for 27.9% of global grid infrastructure investment in 2023, equal to about USD 86.5 billion. 

• China accounted for 25.4% of global grid infrastructure investment in 2023, equal to about USD 78.9 billion.

Figure 1. GIS market scale and grid-demand benchmarks should be reviewed together because compact substations become more valuable as networks carry higher loads. 

Market context readout 
GIS growth is not only an equipment-sales story. It reflects denser cities, higher electrical loads, more renewable generation, and stronger reliability expectations. 

Global GIS Market Size and Forecast 

The global market-size picture should be read as a range rather than a single exact figure. Different research firms use different base years, segmentation assumptions, and regional models. Still, the overall direction is consistent: the GIS market is expected to expand steadily through the next decade as grid owners and industrial buyers invest in compact high-voltage assets. 

This section separates the headline market value from the underlying business case. A market that grows from roughly the high USD 20 billions in the mid-2020s toward USD 50 billion or more in the mid-2030s is large enough to affect product portfolios, utility procurement strategies, component supply chains, and engineering capacity. 

Global forecast benchmarks 

• Future Market Insights estimates the global GIS market at USD 28.1 billion in 2025. 

• The forecast reaches USD 40.91 billion by 2030 and USD 59.6 billion by 2035. 

• Under the FMI forecast path, the market adds about USD 31.5 billion in value between 2025 and 2035.

• Across major market reports, the reported CAGR range is generally between about 6.5% and 7.8%. 

Forecast readout 
Market values vary by source, but the direction is consistent. Most forecasts place GIS in a steady expansion cycle tied to modern grid infrastructure. 

Voltage Segment Statistics 

Voltage segmentation is one of the most important ways to understand GIS demand. Medium-voltage systems support distribution and facility-level reliability, while high-voltage and extra-high-voltage assets are tied to larger substations, transmission corridors, renewable connection, and national grid expansion. Because higher-voltage systems usually carry larger project values, voltage mix can influence revenue more than unit volume alone. 

Voltage demand benchmarks 

• The high-voltage GIS segment is expected to lead with 59.0% market share in 2025. 

• Using USD 28.1 billion, the high-voltage GIS segment equals roughly USD 16.58 billion in 2025. 

• High-voltage GIS is estimated at USD 17.87 billion in 2026 and USD 19.27 billion in 2027. 

• High-voltage GIS reaches about USD 24.14 billion by 2030. 

• The >72 kV to <=150 kV product range is expected to hold 34.0% GIS market share in 2025. 

• That product range is estimated at USD 9.55 billion in 2025, USD 10.30 billion in 2026, and USD 11.10 billion in 2027. 

• The >72 kV to <=150 kV range could reach USD 20.26 billion by 2035. 

• Low-voltage commercial GIS holds 69.2% of the commercial GIS segment. 

• AC commercial GIS holds an estimated 80.0% commercial segment share. 

Figure 2. Segment shares show where GIS demand is concentrated across insulation, voltage, installation, and regional categories. 

Voltage readout 
Voltage segmentation matters because GIS demand is not evenly distributed. Higher-voltage projects often carry larger values, longer procurement cycles, and stronger grid-expansion links. 

Installation Type Statistics: Indoor, Outdoor, and Hybrid GIS 

Installation type explains the physical environment behind GIS demand. Indoor GIS is closely linked to urban substations, commercial districts, underground facilities, metro systems, and industrial sites where land is limited or exposed electrical infrastructure is undesirable. Outdoor GIS remains important in utility yards, transmission substations, renewable interconnection points, and large infrastructure projects where voltage scale and system reliability matter more than building integration. 

Installation benchmarks 

• Outdoor GIS accounted for 58.5% of the GIS market in 2025. 

• Outdoor GIS revenue is estimated at USD 15.38 billion in 2025. 

• Outdoor GIS revenue is estimated at USD 16.38 billion in 2026 and USD 18.58 billion in 2028. 

• Outdoor GIS revenue reaches an estimated USD 23.92 billion by 2031. 

• Outdoor GIS revenue could reach USD 34.87 billion by 2035. 

• Indoor GIS is strongest where land, safety, noise, and footprint constraints matter. 

• Hybrid GIS supports brownfield upgrades that need smaller footprints than AIS. 

Installation readout 
Indoor GIS is usually a space-efficiency decision, while outdoor GIS is often an infrastructure-scale decision. Project economics depend on land, voltage, exposure, and outage risk. 

SF6 and SF6-Free GIS Statistics 

The insulation story is one of the most important modern angles in the GIS market. SF6 has been widely used because of its strong insulation and arc-quenching performance, but it also carries environmental pressure. That makes SF6-free GIS a procurement, compliance, and lifecycle-planning topic, not just a technical product feature. Utilities that buy equipment with long operating lives have to think about future regulation as well as today’s equipment cost. 

SF6 and sustainability benchmarks 

• SF6-insulated GIS captured 67.2% market share in 2025. 

• SF6-insulated GIS equals roughly USD 17.67 billion in 2025. 

• SF6-insulated GIS is estimated at USD 18.82 billion in 2026 and USD 20.04 billion in 2027. 

• SF6-insulated GIS revenue reaches about USD 27.50 billion by 2031. 

• SF6-insulated GIS could reach about USD 40.05 billion by 2035. 

• SF6-free GIS demand is supported by utility decarbonization goals. 

• Europe is the key regulatory region for SF6-free adoption. 

• SF6-free alternatives are most visible in new projects and replacement programs. 

Sustainability readout 
SF6-free GIS is becoming a procurement and lifecycle-planning issue, not only an environmental feature. Regulation and utility targets are reshaping product strategy. 

End-User GIS Demand Statistics 

Utilities remain the anchor end-user category for GIS because transmission and distribution networks require high-reliability switching systems. However, the market is being influenced by a wider set of users. Renewable developers need grid interconnection. Data centers need high uptime and power density. Rail and metro systems need safe compact electrical infrastructure. Heavy industry, mining, oil and gas, and commercial campuses all require reliable high-load power control. 

End-user benchmarks 

• Power utilities are identified as the largest end-user category in the U.S. GIS market. 

• Utility demand is linked to aging substations and reliability upgrades. 

• Renewable developers need GIS where projects require compact interconnection substations. 

• Data center electricity demand is projected to reach around 945 TWh by 2030. 

• Data center electricity demand is projected to grow around 15% per year from 2024 to 2030. 

• Industrial electricity use grew by nearly 4% in 2024. 

• Transport electricity consumption increased by more than 8% in 2024. 

• Commercial GIS is estimated at USD 5.80 billion in 2025 and USD 11.27 billion by 2035. 

End-user readout 
Utilities remain the anchor demand base, but non-utility load centers such as data centers, rail systems, industrial sites, and renewable projects are becoming more important. 

Regional GIS Market Statistics 

Regional data is essential because GIS demand is not one global story. Asia-Pacific is driven by scale, power demand, urbanization, transmission expansion, and renewable connection. North America is shaped by modernization, aging infrastructure, data centers, and renewable grid connection. Europe adds a stronger SF6-free and regulatory angle.

Figure 3. Regional GIS demand differs by scale, upgrade cycles, renewable connection, land pressure, and environmental regulation. 

Regional readout 
Global GIS demand is not one story. Asia-Pacific is scale-led, North America is modernization-led, Europe is regulation-led, and emerging regions are infrastructure-led. 

Country-Level GIS Market Statistics 

Country-level analysis adds practical value because GIS purchasing is tied to local grid plans, utility procurement, renewable pipelines, voltage needs, and land constraints. A country with large electricity demand may not automatically create GIS demand unless grid investment, substation projects, and compact high-voltage needs are present. The most useful country statistics therefore combine market value with the operating reason behind adoption. 

Country benchmarks worth separating 

• The United States GIS market is estimated at USD 6.84 billion in 2025. 

• The United States reaches USD 7.31 billion in 2026 and USD 10.8 billion by 2032.

Country-level readout 
Country-level demand depends on the pressure point: urban substations, renewable connection, replacement cycles, transmission corridors, or industrial infrastructure. 

Renewable Energy and Grid Integration Statistics 

Renewable energy is one of the clearest long-term drivers behind GIS demand. Solar and wind projects often need new substations, interconnection equipment, grid reinforcement, and higher-capacity transmission links. Offshore wind and remote renewable generation can increase the need for compact high-voltage equipment because generation sites are not always close to load centers. 

Renewable and grid-integration benchmarks 

• Global renewable energy capacity is cited at around 3,864.52 GW in 2024. 

• Renewable capacity growth increases pressure on transmission networks. 

• Utility-scale solar and wind projects can create compact-substation demand. 

• Offshore wind strengthens GIS demand in space-constrained substations. 

• The U.S. solar driver shows solar generation expected to rise by 123 billion kWh from 2023 to 2025. 

• Renewable integration is important where transmission expansion is a bottleneck. 

• GIS demand rises when renewables meet high-voltage interconnection needs. 

Renewables readout 
Renewable growth creates GIS demand where projects need compact substations, high-voltage interconnection, offshore infrastructure, or stronger links between generation and load centers. 

Urbanization and Compact Substation Demand 

Urbanization is a practical GIS demand driver because dense cities create high load in locations where land is expensive and space for conventional substations is limited. Air-insulated equipment requires more clearance and a larger physical footprint. GIS reduces the space requirement and makes it easier to place substations indoors, underground, or in constrained utility sites. That is why urban power reliability and land pressure should be analyzed alongside market size. 

Urban grid benchmarks and implications 

• Urban GIS demand is strongest where land cost and load density are high. 

• Indoor GIS is useful for city-center substations and underground facilities. 

• Outdoor GIS helps utility yards add capacity without major footprint expansion. 

• Smart city infrastructure can support compact GIS demand. 

• Brownfield substation upgrades often require capacity without new land. 

• Public safety and reliability are important urban GIS factors. 

Urban readout 
GIS is most valuable where land is expensive, load is dense, and utilities cannot easily expand conventional air-insulated substations. 

Data Centers, AI Load Growth, and Industrial Electrification 

Data centers and industrial electrification are not always direct GIS categories in market reports, but they are powerful demand signals. A data center campus, semiconductor plant, battery factory, mining operation, or electrified industrial site can require large power connections and high reliability. Those loads pressure utilities to reinforce substations and transmission networks, while private owners may need compact high-capacity electrical infrastructure on or near site. 

Power-demand benchmarks 

• Global data center electricity consumption is projected to reach around 945 TWh by 2030. 

• Data center electricity demand is projected to grow around 15% per year. 

• Industrial electricity use grew by nearly 4% in 2024. 

• Transport electricity consumption increased by more than 8% in 2024. 

• Industry contributed nearly 40% of total electricity demand growth in 2024. 

• Advanced economies added 230 TWh of electricity consumption in 2024. 

• Global electricity demand growth accelerated by 1.8 percentage points from 2023 to 2024. 

Figure 4. Electricity demand, grid investment, data centers, industry, and transport growth all support long-term GIS adoption. 

Demand-driver readout 
Data centers and industrial electrification increase pressure on power networks. That pressure can favor compact, reliable, high-capacity substation equipment. 

Competitive Landscape and Manufacturer Strategy 

The GIS competitive landscape is shaped by engineering depth, high-voltage product range, utility relationships, digital monitoring capability, service support, delivery reliability, and SF6-free innovation. Large electrical equipment manufacturers compete not only on the nameplate rating of switchgear, but also on lifecycle cost, compact design, substation integration, standards compliance, and the ability to support complex utility projects over many years. 

Manufacturer strategy benchmarks 

• Leading GIS manufacturers include ABB, Siemens Energy, Schneider Electric, Hitachi Energy, and GE Vernova. 

• SF6-free product development is becoming a strategic differentiator. 

• Digital GIS monitoring supports predictive maintenance and asset management. 

• Compact modular GIS supports brownfield upgrades and urban substations. 

• High-voltage product depth matters for utility and renewable interconnection projects. 

• Retrofit and lifecycle service capability supports modernization demand. 

• Delivery reliability matters because long equipment lead times can delay grid projects. 

Competitive readout 
GIS manufacturers compete on compact design, SF6-free technology, digital monitoring, service capability, delivery reliability, and long-term utility trust. 

GIS Market Risks and Constraints 

The GIS market has strong growth drivers, but adoption is not automatic. Buyers still compare GIS with air-insulated switchgear, hybrid configurations, and other electrical infrastructure options. The choice depends on footprint, voltage, reliability requirements, lifecycle cost, environmental rules, maintenance capability, and project schedule. A high headline CAGR does not remove the need for project-by-project justification. 

Cost, maintenance, regulation, and supply-chain constraints 

• GIS carries a higher upfront cost than air-insulated switchgear. 

• SF6 regulation creates long-term planning risk for utilities that expect equipment to remain in service for decades. 

• SF6-free alternatives may require new procurement standards and validation. 

• Skilled maintenance needs can slow adoption in service-constrained markets. 

• Long utility procurement cycles can slow reported market growth even when project demand is strong. 

• Supply-chain delays can affect GIS project timelines. 

• Air-insulated switchgear remains competitive where land is available. 

Risk interpretation 
GIS adoption depends on local project economics. Buyers compare cost, footprint, maintenance complexity, insulation technology, schedules, and regulatory risk. 

GIS Market Opportunity Diagnostic 

A polished GIS statistics article should help a reader decide where to look next. The most useful approach is not to chase one global CAGR, but to connect demand signals to practical opportunities. GIS demand becomes most attractive where multiple indicators overlap: high load growth, land constraints, renewable interconnection, aging substations, strict reliability needs, and regulation-driven equipment replacement. 

Opportunity readout 
The best GIS opportunities appear where multiple signals overlap: load growth, limited land, renewable connection, aging substations, reliability needs, and regulation-driven replacement. 

90-Day GIS Market Research Plan 

Statistics become more useful when they are translated into a research workflow. For a GIS market project, the best starting point is to build a baseline, compare growth drivers, and then validate manufacturer and procurement signals. This keeps the article from becoming a list of facts and turns it into a practical planning model. 

Planning principle 
The strongest GIS analysis does not rely on one global CAGR. It compares forecasts with grid investment, voltage needs, land constraints, regulation, and procurement behavior. 

Metrics GIS Market Analysts Should Track 

A useful scorecard should be detailed enough to show where GIS demand is coming from without becoming a vanity dashboard. The metrics below separate market size from demand quality, regional fit, segment mix, and procurement risk. 

Utility Procurement and Replacement-Cycle Statistics 

GIS adoption is shaped by how utilities buy long-life infrastructure. A power company does not replace a substation the way a business replaces software. Procurement usually moves through planning studies, engineering design, budget approval, tendering, factory testing, delivery, installation, commissioning, and maintenance planning. That makes the market slower than consumer technology, but it also creates durable demand once a project is approved. 

Procurement benchmarks worth separating 

• GIS projects often sit inside multi-year grid programs, so demand can appear in procurement pipelines before it appears in annual market revenue. 

• The USD 28.1 billion 2025 market estimate should be read alongside long utility planning cycles because substation decisions usually affect assets for decades. 

• High-voltage GIS demand is more sensitive to transmission planning than to short-term equipment replacement because project values are larger and engineering reviews are longer. 

• Outdoor GIS with 58.5% market share shows that large utility yards, transmission sites, and renewable interconnection points remain important buying environments. 

• Indoor GIS demand is strongest where land cost, outage risk, public safety, and space constraints justify a higher upfront equipment cost. 

• SF6-free procurement is most likely to move first in utilities with formal decarbonization targets, strict environmental rules, or long-term asset-management frameworks. 

• A utility evaluating GIS usually compares footprint, lifecycle cost, voltage class, maintenance access, insulation technology, and outage exposure rather than purchase price alone. 

• Brownfield substations can create strong GIS demand because compact equipment may allow upgrades without acquiring new land. 

• Renewable interconnection projects can pull GIS demand forward when developers need faster, compact, and high-reliability switching near constrained grid nodes. 

• Data center grid requests can also influence GIS demand indirectly by pushing utilities to reinforce substations near high-load campuses. 

Procurement readout 
GIS buying is rarely a single-price decision. The strongest projects connect technical need, land pressure, lifecycle cost, reliability risk, and long-term regulation. 

Lifecycle Cost, Reliability, and Maintenance Statistics 

The market case for GIS becomes clearer when the analysis moves beyond first cost. GIS can cost more than air-insulated switchgear at the equipment stage, but the business case can change when land, building work, outages, maintenance exposure, reliability, and asset life are included. This is why GIS often appears in dense cities, industrial zones, airports, metros, data centers, and high-value transmission nodes. 

Reliability and lifecycle benchmarks 

• GIS is commonly selected where compact footprint and equipment protection are more valuable than the lowest upfront switchgear cost. 

• High-voltage systems with 59.0% market share show that reliability-sensitive transmission and grid-connection projects remain central to GIS revenue. 

• The 67.2% SF6-insulated share shows that proven insulation performance still matters, even as alternatives gain policy and procurement attention. 

• SF6-free alternatives are becoming more important because utilities must think about leakage, reporting, compliance, and end-of-life handling over the full asset cycle. 

• A substation designed for 30 years or more must account for future regulation as well as current equipment price. 

• Digital monitoring can improve the GIS value case when it helps teams detect gas pressure issues, temperature changes, partial discharge risks, or maintenance needs earlier. 

• Industrial users often value GIS when an electrical outage can interrupt production, mining, refining, rail service, or critical facility operations. 

• Urban utilities can justify GIS when a smaller substation footprint avoids land acquisition, permitting delays, public exposure, or building constraints. 

• Lifecycle analysis is especially important in Europe, where SF6 policy pressure can affect long-term procurement, retrofit, and replacement planning. 

• A strong GIS business case compares total project cost, not only equipment cost, because civil works, land value, outage risk, and maintenance access can change the economics. 

Lifecycle readout 
GIS economics improve when the analysis includes land, outages, regulation, maintenance, and asset life. In many projects, footprint and reliability are the real value drivers. 

Digital GIS, Monitoring, and Smart Substation Statistics 

Modern GIS demand is also connected to the shift toward digital substations. Utilities increasingly want equipment that can be monitored, integrated, and maintained with better data. This does not replace the core electrical role of GIS, but it changes how buyers evaluate product value, service contracts, and long-term operating performance. 

Smart substation benchmarks 

• Digital monitoring is most useful where high-voltage equipment operates in critical substations, dense cities, industrial zones, or remote renewable sites. 

• Predictive maintenance becomes more valuable when grid assets are aging and skilled maintenance teams are stretched across large service territories. 

• Gas-pressure monitoring can support GIS reliability planning because insulation performance depends on stable operating conditions. 

• Temperature, partial discharge, switching operation, and condition-monitoring data can help operators prioritize maintenance before failures become outages. 

• Smart substations are especially relevant in markets investing heavily in renewables, because variable generation increases the need for flexible and observable grid infrastructure. 

• Data center demand supports smart substation investment because high-load campuses require reliable power, fast fault response, and strong utility coordination. 

• Digital GIS features can support manufacturer differentiation when equipment capacity, voltage rating, and compactness are otherwise similar. 

• Service revenue can become more important as manufacturers offer monitoring, maintenance, retrofit, and lifecycle support around installed GIS assets. 

• Utilities can use digital monitoring to compare asset condition across substations and reduce unnecessary field inspections at lower-risk sites. 

• The strongest smart-GIS value case appears where reliability risk, high load density, and expensive outages overlap.

Digital features do not replace core GIS performance. They strengthen the value case when monitoring improves reliability, maintenance planning, and operating confidence. 

Country-Level Planning Signals for GIS Suppliers 

Country-level analysis is important because the reason for GIS adoption changes by market. Some countries need GIS because transmission corridors are expanding. Others need it because cities are dense, offshore wind is growing, industrial zones require reliable power, or SF6 procurement rules are changing. A supplier that treats the market as one global average can miss where demand is most practical. 

Country planning benchmarks 

• The United States is a modernization-led market, with GIS demand tied to aging substations, data center growth, renewables, and reliability upgrades. 

• China is a scale-led market because large grid programs, urban infrastructure, UHV transmission, and renewable connection can support high-voltage equipment demand. 

• India is a growth-led market where power demand, electrification, industrial expansion, and renewable targets can support new substation capacity. 

• Germany is a regulation-led and energy-transition market where SF6-free procurement, renewable grids, and replacement planning are especially important. 

• The United Kingdom adds offshore wind and grid-reinforcement pressure, making high-voltage substations and coastal infrastructure important demand points. 

• Saudi Arabia and the UAE are infrastructure-led markets where utility expansion, industrial zones, and megaprojects can support compact high-reliability equipment. 

• Brazil and Mexico represent selective growth opportunities where renewable projects and transmission expansion can create targeted GIS demand. 

• Japan and South Korea are reliability-led markets where dense urban grids, advanced utilities, and industrial load centers can support compact substation investment. 

• Southeast Asian markets require local analysis because power demand, land constraints, utility budgets, and grid maturity differ sharply by country. 

• Australia combines renewable buildout, mining loads, and grid-distance challenges, making transmission planning an important GIS demand signal. 

Country planning readout 
The best country analysis starts with the local grid problem. GIS demand is strongest when the technology directly solves land, voltage, reliability, regulation, or interconnection constraints. 

How Manufacturers Should Read the GIS Statistics 

For manufacturers, the strongest statistics are not only market-size numbers. Segment shares, regional demand, voltage classes, insulation trends, utility procurement cycles, and lifecycle service needs all shape commercial strategy. A manufacturer may see the same global CAGR as competitors, but the winning strategy depends on where it can solve a more specific buyer problem. 

Manufacturer strategy benchmarks 

• A 7.8% long-term CAGR supports capacity planning, but it does not identify which voltage class or region should receive the most sales attention. 

• The 35.0% Asia-Pacific share highlights the importance of scale markets, but country-level demand still varies between China, India, Japan, South Korea, and Southeast Asia. 

• The 59.0% high-voltage share points manufacturers toward transmission, renewable interconnection, and utility reinforcement opportunities. 

• The 58.5% outdoor installation share shows that large utility and infrastructure projects remain important even as indoor urban GIS demand grows. 

• The 67.2% SF6-insulated share confirms that existing technology remains dominant, but it also creates a transition opportunity for SF6-free portfolios. 

• Service, retrofit, and monitoring offers can help manufacturers capture value after the initial equipment sale. 

• Lead-time reliability can become a competitive advantage because delayed high-voltage equipment can affect renewable, utility, and industrial project schedules. 

• Local standards, utility relationships, testing requirements, and after-sales support can matter as much as headline product specifications. 

• Manufacturers with both high-voltage capability and SF6-free roadmaps are better positioned for markets where regulation and grid expansion overlap. 

• The most useful commercial scorecard combines market size, regional share, voltage mix, insulation type, service opportunity, and procurement timing. 

Manufacturer readout 
GIS suppliers should treat statistics as a targeting tool. The best opportunities are defined by region, voltage, insulation technology, service need, and procurement timing.
