Electricity Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Electricity Market Trends and Insights

Data Center and AI Load Expansion

AI-oriented servers consumed 175 TWh of electricity in 2026, compared with 95 TWh in 2025, which makes data center demand a near-term source of growth for the global electricity market^{[1].International Energy Agency, “Energy and AI,” International Energy Agency, iea.org} The IEA expects total global data center electricity use to reach 565 TWh in 2026 and approach 945 TWh by 2030 in its base case. This demand is concentrated, so access to reliable networks, prompt interconnection, and clean power is influencing where new facilities are built. Northern Europe, Texas, and Southeast Asia can benefit from permitting and dedicated renewable tariffs that support faster connections. Five large technology companies spent more than USD 400 billion in 2025 and are expected to increase capital spending further in 2026, adding pressure for new generation and network capacity. These investments give electricity suppliers opportunities, but they also raise the risk that local infrastructure falls behind project pipelines.

Industrial and Manufacturing Electrification

Industrial electricity demand is supported by the replacement of fossil-fuel heat with electric equipment and the growth of electricity-intensive manufacturing. Europe’s industrial electrification rose by 1 percentage point in 2024 despite a power mix that was already 72% decarbonized, showing that network capacity and project economics remain important barriers^{[2]Eurelectric, “Power Couples Enhancing Industrial Competitiveness Through Electrification,” Eurelectric, eurelectric.org}. China’s industrial sector consumed 6,518 TWh in 2025, reflecting the continuing shift of manufacturing capacity toward Asia. Solar module, battery, and electric vehicle manufacturing in China used more than 300 TWh each year from 2022 to 2024. The global electricity market, therefore, depends increasingly on a smaller number of high-load industrial clusters rather than only on broad economic growth. Industrial electrification can strengthen the utilization of clean power, but it also creates localized congestion where factories connect faster than grid upgrades are completed.

Electric Vehicle and Transport Electrification

Transportation is becoming a faster-growing source of electricity use as electric vehicles enter more passenger, bus, and two- and three-wheeler fleets. Electricity used by EV charging services in China rose 56.9% year over year in the first half of 2026^{[3]China National Energy Administration, “2025 National Electricity Consumption Data,” National Energy Administration, nea.gov.cn}. Charging demand differs from industrial and household load because it can move across locations and concentrate during particular hours. Grid operators in South Korea, the Netherlands, and California are using vehicle-to-grid programs and time-of-use tariffs to manage these patterns. The global electricity market can gain from flexible charging, although distribution networks must be prepared for rapid local increases in demand.

Renewable and Nuclear Capacity Expansion

Renewable capacity reached 5,149 GW at the end of 2025, equal to 49.5% of global installed electricity capacity, after 692 GW was added during the year^{[4]International Renewable Energy Agency, “Renewable Power Generation Records Its Fastest Growth Ever,” International Renewable Energy Agency, irena.org}. Solar PV added 511 GW in 2025 and brought cumulative capacity to 2,392 GW. This supply buildout supports the global electricity market because new solar and wind can meet part of the additional load from industry, vehicles, and data centers. It also increases the need for balancing, storage, and transmission when production is not aligned with demand. Nuclear generation reached a record in 2025 and is expected to continue growing, with China accounting for a large share of the increase through 2030. Renewable and nuclear additions improve supply diversity, but their value depends on grid operation and the ability to deliver electricity to load centers.

Grid Connection Queues and Interconnection Bottlenecks

Grid connection delays remain a central restraint on the global electricity market because projects cannot contribute to supply or serve new load before network studies and upgrades are completed. At the end of 2025, 2,061 GW of generation and storage capacity were seeking interconnection in the United States across almost 8,200 projects. The median wait from application to commercial operation exceeded 5 years. Sequential study processes, cost allocation rules, and staffing limits at system operators have prolonged these queues. FERC reforms increased completed interconnection agreements by 33% in 2024, but the existing backlog remains significant. The same challenge is present in other regions, where project timelines depend on permitting and the pace of investment in transmission.

Transmission Equipment and Critical Mineral Supply Exposure

Transformer and switchgear availability can slow additions to the global electricity market even after a project has secured financing and permits. Demand for generation step-up transformers in the United States increased 274% by 2025, and average lead times reached 128 to 143 weeks by the second quarter of 2025. Domestic production met only 20% of U.S. large power transformer demand in 2025, leaving the remaining requirement dependent on imports. Medium-voltage switchgear and circuit-breaker prices rose sharply, increasing connection costs. The shortage reflects limited specialist manufacturing capacity and a constrained coil-winding workforce rather than only a shortage of capital. Government grid hardware programs and interoperability standards can improve procurement over time, but the draft indicates that meaningful relief is unlikely before 2028.

Segment Analysis

By Electricity Generation Source: Coal Leads, but Solar Is Reshaping Economics

Coal held 32.6% of the global electricity market share in 2025, making it the largest individual generation source. Coal generation fell by 63 TWh in 2025 as renewable output exceeded coal in the global mix for the first time in more than a century, showing that installed coal capacity and delivered generation can follow different paths. New coal commissioning reached 97.4 GW in 2025, with China accounting for 78.1 GW and India for 10 GW. Hydropower and bioenergy also remain important in countries where local resources support them.

Renewable electricity is the fastest-growing source, with an 8.2% CAGR forecast through 2031. The global electricity market size for renewable generation is supported mainly by solar PV, which added 636 TWh of output in 2025. The IEA expects solar to add close to 600 TWh of generation annually through 2030. Wind and solar reduce fossil generation where their output matches demand, but they require systems that manage variation across hours and seasons. The global electricity industry is adding capacity while increasing its need for flexible operation.

By Electricity Consumer: Industrial Demand Is Largest, While Transportation Rises Fastest

Industrial users accounted for 42.1% of the global electricity market share in 2025, the largest share among consumer groups. The concentration of energy-intensive production in Asia supports this position. Industry represented 60% of China’s electricity consumption, compared with an OECD average of 32%, and it accounted for 48% of China’s electricity-demand growth from 2022 to 2024. Residential consumers held the next-largest position, followed by commercial users affected by data center activity. Agricultural and other users are smaller contributors, although irrigation electrification is increasing their use in emerging economies.

Transportation is forecast to grow at a 9.4% CAGR through 2031, the highest rate among consumer categories. Electricity use by EV charging services in China increased 56.9% year over year in the first half of 2026. The global electricity market size for transportation depends not only on vehicle sales, but also on when and where charging takes place. The Energy Systems Integration Group identifies flexible EV demand as a planning factor that utilities still need to improve in their load forecasts. Utilities can invest in smart charging, local network upgrades, and tariffs that direct charging toward less constrained periods.

By Generation Type: Centralized Generation Remains Largest, While Distributed Systems Expand

Centralized generation accounted for 88.3% of the global electricity market share in 2025. Utility-scale solar and wind are centralized assets despite their role in lower-carbon power. Nuclear stations, large hydropower projects, and gas-fired plants also retain this model. It supports large, stable loads but requires substantial capital and long planning periods. Interconnection queues show the gap between rising demand and completed centralized projects.

Distributed generation is forecast to grow at a 7.6% CAGR through 2031. The United States added 6.8 GW of distributed solar in 2025, and solar represented more than three-quarters of new electricity-generating capacity in the country. Distributed installations represented 50% of global solar additions in 2024, supported by incentives in the United States, Europe, China, and India. This expansion changes the global electricity market because customers can produce, store, and manage electricity closer to consumption points. Higher distributed generation can reduce network throughput and pressure utility cost-recovery models.

Geography Analysis

Asia-Pacific accounted for 51.9% of the global electricity market size in 2025 and is forecast to grow at a 4.5% CAGR through 2031, the highest regional rate. China, India, Southeast Asia, and Australia are the main sources of regional demand and supply expansion. China’s electricity consumption exceeded 10.37 PWh in 2025, while high-technology manufacturing and internet data services showed strong growth in the first half of 2026. NTPC added 9.6 GW in fiscal year 2025-26, including 5.5 GW of renewable capacity, and is targeting 250 GW by fiscal year 2037. Asia-Pacific contributed 74.2% of new global renewable capacity additions in 2025.

North America and Europe together represented one-third of global electricity use and grew at more moderate rates. U.S. electricity consumption increased 2.1% in 2025 and is forecast to rise 2% annually through 2030, with data centers responsible for half of the additional national demand. European electricity consumption rose by less than 1% in 2025 and is not expected to return to its 2021 level until 2028. The European Commission’s Electrification Action Plan supports a medium-term increase in demand, including industrial electrification potential identified at more than 2,000 TWh by 2040/

South America, the Middle East, and Africa offer uneven but material expansion opportunities for the global electricity market. Middle Eastern electricity demand rose 4% in 2025 because of cooling, population growth, and industrial expansion. Saudi Arabia reduced oil burn for power generation by 100,000 barrels per day in 2025 as gas capacity from Jafurah and renewable projects came online. Renewable capacity in Africa increased 15.9% in 2025 and capacity in the Middle East grew 28.9%, although both started from lower levels. Brazil’s hydropower-led system remains exposed to seasonal variation, which sustains a need for thermal backup.
