Energy Storage, UHV, Solid-State Transformers: Three Major Global Power Equipment Trends

The global power equipment market will see clear divergence across its segmented tracks in 2026. UHV power transmission and transformation, large-scale complete energy storage equipment, and silicon carbide solid-state transformers (SST) stand out as the three hottest sectors in the industry.

UHV Power Equipment

The global UHV market reached USD 34.5 billion in 2025 and is projected to rise to USD 55 billion by 2030, representing a compound annual growth rate (CAGR) of over 10%. Concentrated construction is underway for DC transmission lines to deliver wind and solar power in the Middle East, desert and Gobi regions, and Southeast Asia. Converter transformers, converter valves and GIS combined electrical appliances are the core tendered product categories. Leading equipment manufacturers are running at full capacity, with long-term framework orders continuously secured.

Complete Energy Storage Equipment

High-voltage cascaded energy storage solutions have become the mainstream technical route for hundred-megawatt standalone energy storage and wind-solar supporting energy storage. Eliminating the need for step-up transformers, this solution will account for more than 20% of the global market in 2026. Supply of liquid-cooled energy storage prefabricated cabins and complete equipment for energy storage collection stations remains tight worldwide. Converters for sodium-ion energy storage have entered the large-scale demonstration phase.

Solid-State Transformers (SST)

Solid-state transformers (SST) have hit a commercial inflection point. Serving as core energy routing devices for AI computing centers, they are compatible with the 800V DC data center architecture. Their volume is only 30%–50% of conventional transformers, and power conversion efficiency can reach 98.5%. Many domestic and overseas enterprises have launched commercial products with deep integration of silicon carbide power devices. SST is poised to become core equipment for future distribution networks and computing power power supply systems.
