Industry Trends

Findings from Market Research Future identify localization of manufacturing as a defining strategic trend. Companies are increasingly localizing manufacturing to reduce lead times and optimize supply chains, and this approach appears to be a response to the growing need for agility in production and distribution, with the market structure moderately fragmented and the influence of major companies remaining substantial. A second trend is the shift toward HVDC capability, illustrated by GE Vernova announcing in March 2026 approximately $200 million investment in a new Hai Phong, Vietnam facility to manufacture large power transformers primarily for HVDC transmission projects, complementing its existing HVDC transformer plants in Stafford, UK, and India, and by Toshiba Energy Systems receiving in March 2026 an order from J-POWER Transmission Network for a self-commutated HVDC system comprising converters, transformers, and control/protection systems for the renewal of Pole 1 of the Hokkaido-Honshu HVDC Link, with operation targeted for FY2031. Third, data centre demand is becoming a distinct order category, illustrated by Schneider Electric Infrastructure reporting in May 2026 FY26 new order inflow of Rs 3,430 crore up 27.4% year-on-year including major data centre orders covering power transformers, relays, and circuit breakers, and by CG Power and Industrial Solutions securing in January 2026 its largest-ever single order valued at approximately ₹900 crore (US$99.2 million) from Tallgrass Integrated Logistics Solutions to supply power transformers engineered for hyperscale data centre reliability requirements in the United States.

Challenges

Manufacturers face constraints that limit how quickly they can respond to demand. Large power transformers are bespoke engineered products rather than catalogue items, and each unit is designed for a specific voltage, impedance, and site condition, which limits throughput and extends lead times. Skilled labour for winding, core stacking, and testing is in limited supply, and capacity expansion requires recruiting and training workers who may not exist in the local labour market, which is why new plants in India and Vietnam have commissioning dates in 2027, 2028, and even 2030 to 2032. Weight and dimensional constraints mean transport routes must be surveyed and roads or bridges reinforced, adding logistical complexity to every delivery. Raw material costs for electrical steel, copper, and insulation are volatile, and long manufacturing cycles expose manufacturers to price movements between order and delivery. Export controls and trade policy can restrict access to markets and to specialised components.

Future Outlook
