China’s Transformer Makers See Export Surge as Global Grid Crunch Deepens
A critical bottleneck in global power infrastructure and the burgeoning artificial intelligence sector has shifted leverage in the heavy equipment market, positioning Chinese manufacturers as the primary beneficiaries of a worldwide transformer shortage. With demand driven by aging Western grids, the renewable energy transition, and power-hungry data centers, the global supply chain is increasingly relying on China, which currently commands 60% of global production capacity.
The severity of the shortage has begun to override geopolitical trade barriers. While the United States previously imposed a 104% tariff on Chinese transformers, reports indicate a quiet relaxation of restrictions as domestic supply gaps widen. Elon Musk, speaking at the 2024 Bosch Connected World conference, predicted that a transformer shortage would follow the chip shortage, a forecast that has materialized as projects in Europe and India stall due to equipment unavailability.
This imbalance has triggered a surge in orders for Chinese industry leaders, with many manufacturers fully booked beyond 2026. European buyers are reportedly paying premiums of up to 20% to secure immediate supply, pushing the average export price of Chinese transformers to approximately US$20,800 per unit. In the first eight months of 2025 alone, Chinese transformer exports reached RMB 29.71 billion (US$4.25 billion), with shipments to Europe skyrocketing by over 138%.

The Structural Supply Deficit
The current crisis stems from a confluence of aging infrastructure and new, energy-intensive technologies. According to data cited from Goldman Sachs and Bank of America, a significant portion of the grid in Europe and the US has been in operation for 40 to 50 years. In the US, supply gaps for power transformers and distribution transformers have surged by 116% and 41% respectively compared to 2019 levels.
Simultaneously, the AI boom and the green transition are compounding demand. A mid-sized data center for Meta Platforms Inc. requires hundreds of step-down transformers, while solar power stations demand 1.8 times the transformer capacity of equivalent coal-fired plants. Consequently, the "Allied Market Research" agency projects the global transformer market will nearly double from US58.6billionin2021toUS58.6billionin2021toUS103 billion by 2031.
Major international players, including Siemens Energy AG, Hitachi Energy, and Schneider Electric SE, have announced multi-billion dollar expansion plans. However, with new capacity taking time to come online, the immediate demand is flowing to China’s established industrial base.
China’s Production Dominance
China’s ability to capitalize on this shortage is underpinned by a consolidated and vertically integrated supply chain. The state-owned China Electrical Equipment Group, formed in 2021 through the merger of legacy players including China XD Electric and Baoding Tianwei Baobian Electric, anchors the "national team." These entities have extensive experience in ultra-high voltage (UHV) projects and export to over 40 countries.
The private sector is equally robust. TBEA consistently ranks as a top global producer by output, with an annual capacity of 420 million kVA. Jiangsu Huapeng Transformer leads in exports for new energy transformers, and Igor (Foshan) Electric holds a leading position in step-up transformers for solar and storage applications. Manufacturers like Chengdu Xidian reported moving immediately from fulfilling orders for Sweden and Saudi Arabia to producing for Canada and Indonesia.
Crucially, China dominates the upstream supply of grain-oriented electrical steel, a core material that reduces energy loss. Baoshan Iron & Steel has developed the world's only specialized production line for high-grade 0.18mm and 0.20mm silicon steel. In 2024, China’s output of this critical material reached 3.03 million tons—five times that of Japan and eight times that of the US.
Infrastructure Investment as a Precursor
China’s current export capability is the result of decades of domestic grid modernization. Following early reliance on imports from Japan and Germany in the 1980s, China aggressively pursued localization, culminating in the "West-to-East Power Transmission" project launched in 2005. This initiative necessitated the development of UHV transmission technologies (1000kV AC and ±800kV DC) to transport electricity over thousands of kilometers with minimal loss.
The technical hurdles of UHV development, such as creating 500-ton transformers with specialized insulation paper to replace massive ceramic structures, forced Chinese engineers to build a comprehensive domestic supply chain. By 2025, China’s UHV DC lines exceeded 40,000 kilometers.
This domestic capacity building has resulted in a massive disparity in power generation. By July 2025, China’s monthly power generation exceeded 1 trillion kWh, roughly equivalent to Japan's annual consumption. While parts of the US and Europe continue to face grid reliability issues, China’s grid stability and massive renewable installations—including the world’s largest hydro, wind, and solar capacities—provide a stable industrial base for its manufacturers.
Strategic Implications
The transformer shortage highlights electricity's role as a fundamental input for industrial competitiveness. With electricity costs constituting over 30% of expenses in sectors like steel and chemicals, and serving as the lifeblood for AI computing power, grid reliability is becoming a decisive factor in economic performance.
As major economies attempt to re-shore manufacturing and accelerate AI development, the availability of power infrastructure hardware has become a strategic choke point. For now, the solution to alleviating this bottleneck resides heavily within China’s manufacturing sector.
