The global transformer market is undergoing a significant transformation, driven by surging electricity demand, rapid infrastructure development, and the global push toward renewable energy. Valued at USD 57.4 billion in 2024, the market is expected to grow at a CAGR of 5.3% from 2025 to 2035, reaching USD 100 billion by 2035. This growth reflects a broader shift in energy systems worldwide from aging, centralized power grids to smarter, greener, and more decentralized networks.

As governments, utilities, and private stakeholders race to decarbonize and modernize their power infrastructure, transformers are emerging as critical enablers of this transition.

Key Growth Drivers and Industry Shifts

The transformer industry is not just riding a wave of electrification it’s helping shape it. The increasing integration of solar, wind, and hydro power into the grid is creating demand for efficient, adaptive transformers capable of handling intermittent power flows. Additionally, expansion of smart grid systems, electrification of transportation, and energy-efficient transmission are reshaping the expectations from transformer manufacturers.

That said, the market is not without its challenges. Raw material price volatility, environmental regulations, and the need for sustainable solutions are placing pressure on both costs and innovation cycles. However, these same challenges are pushing the industry to develop green and smart transformers that will power the next generation of global energy systems.

Market Overview: Electrification, Urbanization, and Renewable Energy

The world is becoming increasingly electric. Whether it's smart cities, EVs, or data centers, almost every industry is consuming more power. Countries such as China, India, and Japan are rapidly expanding their transmission infrastructure to accommodate both rising urban populations and renewable energy generation. This is driving demand for transformers across power, distribution, isolation, and instrument categories.

The power transformer segment accounted for 45% of the market in 2024, and it is expected to maintain this dominance. These transformers are essential for stepping up voltages for long-distance transmission and stepping them down for commercial and residential distribution. As utilities invest in high-voltage lines and interconnectors for cross-border energy flows, demand for robust, high-capacity transformers will only grow.

Energy Efficiency and Regulation: A Turning Point for Innovation

Governments around the world are mandating energy-efficient equipment in power systems. The EU’s Ecodesign Directive Tier 2, which came into force in 2021, aims to reduce transformer energy losses by 10%. Meanwhile, the U.S. Department of Energy (DOE) has introduced new standards effective from 2027, pushing for the adoption of amorphous steel cores in distribution transformers.

In the UK, major utilities like National Grid, SSE, and ScottishPower are investing £77 billion (2026–2031) in grid modernization, including £35 billion toward upgrading high-voltage cables in England and Wales. These efforts are aimed at increasing energy transport capacity and enabling the electrification of industries.

Such regulatory pressure is accelerating R&D investments in smart, low-loss transformer technologies, creating lucrative opportunities for innovators and manufacturers alike.

The EV Boom: Charging Ahead with Transformers

The electrification of transport is another key growth vector. As electric vehicle (EV) adoption accelerates, countries are rushing to deploy nationwide EV charging infrastructure, placing increased demands on local transformers. According to the International Energy Agency (IEA), the installed base of residential EV chargers will exceed 270 million units by 2035.

In markets like India, where EV penetration is expected to reach 30% by 2030, this will require billions in grid reinforcement. The India Energy Storage Alliance (IESA) estimates that US$ 20–30 billion in investment will be needed just to meet charging infrastructure demand.

Each charging point needs a distribution transformer capable of managing fast charging loads, power fluctuations, and reliability expectations. As EV sales increase, the demand for high-performance transformers will become even more critical.

Regional Spotlight: East Asia Leads the Way

East Asia is currently the largest market, accounting for 33.6% of global share in 2024, and it is expected to grow steadily through 2035. China, Japan, and South Korea are at the forefront, driven by massive infrastructure projects, industrial expansion, and the world’s largest renewable energy networks.

China alone boasts one of the most extensive high-voltage transmission systems and is the world’s largest manufacturer of transformers. With rising investments in ultra-high voltage (UHV) networks and renewable integration, the region is expected to maintain its dominance well into the next decade.

Meanwhile, North America and Europe are focusing on grid modernization and decarbonization, ensuring significant market activity in these mature economies as well.

Key Players and Strategic Developments

The transformer market remains consolidated, with a few major players commanding a significant portion of global share. These include:

• ABB
• Schneider Electric
• Siemens AG
• Hitachi Energy
• Mitsubishi Electric
• CG Power & Industrial Solutions
• Delta Electronics
• Eaton Corporation
• Bharat Heavy Electricals Ltd. (BHEL)

Recent notable developments include:

• Schneider Electric announced in March 2025 its plans to expand transformer production capacity globally to meet growing demand.
• CG Power invested US$ 15 million in June 2023 to expand its manufacturing capacity in India, raising its power transformer capacity to 25,000 MVA and distribution transformer capacity to 9,900 MVA.

These moves reflect the industry's commitment to scaling operations, improving efficiency, and meeting evolving global standards.

Future Outlook: Smart, Green, and Global

As the global energy transition accelerates, the role of transformers will become even more central. Emerging trends that will shape the market through 2035 include:

• Smart transformers integrated with IoT for real-time performance monitoring.
• Eco-friendly materials and designs with low lifecycle emissions.
• Digitally controlled grids and AI-driven fault prediction.
• Expansion into developing regions with rapidly growing electricity demand.

Whether enabling EV charging, integrating offshore wind farms, or supporting urban energy demands, transformers are the unsung heroes of the energy revolution.

Final Thoughts

The transformer market is no longer a slow-moving utility sector—it’s a dynamic, high-stakes industry at the heart of the global energy transition. With investment momentum, regulatory tailwinds, and surging electricity demand, this market is set to nearly double in value by 2035.

For companies in the transformer ecosystem, the next decade offers a rare combination of opportunity and responsibility—to build smarter, greener, and more resilient energy infrastructure that powers the world forward.
