Energy Storage Business Delivers Explosive Growth, Emerging as a Key Growth Driver

According to the company’s latest annual results, Sun.King Technology delivered strong overall performance in 2025. Total revenue reached RMB2.255 billion, representing a 40% year-on-year increase, while net profit attributable to shareholders rose 35% year-on-year to RMB138 million, both reaching record highs.

Among its business segments, the renewable energy generation and energy storage division recorded the fastest growth. Revenue from this segment reached RMB577 million in 2025, surging 111% year-on-year. The company had previously expanded into renewable power station construction and energy storage system-related businesses, and with the continued rapid growth of domestic renewable energy installations, rising energy storage demand has begun translating into large-scale order execution.

At the industry level, the “green power + energy storage” theme has become a major investment focus during China’s 15th Five-Year Plan period. As wind and solar installations continue to increase, power grids are facing rising demand for flexible regulation capabilities, power electronics equipment, and energy storage systems. Sun.King Technology’s longstanding expertise in power electronic devices and systems has therefore prompted the market to reassess its long-term growth potential.

Power Semiconductor Revenue More Than Doubles as Domestic Substitution Theme Gains Momentum

In addition to energy storage, the company’s self-developed power semiconductor business has also become a key market focus. In 2025, revenue from the power semiconductor segment reached RMB121 million, up 104% year-on-year. The company added 55 new mass-production customers, covering sectors such as photovoltaics, energy storage, industrial control, and commercial electric drive systems. Some products have gradually entered the supply chains of leading industry customers.

In recent years, demand for power semiconductor products such as IGBTs and silicon carbide (SiC) devices has continued to expand rapidly, particularly in electric vehicles, energy storage systems, and data centers. Sun.King Technology is accelerating the development of 2300V IGBT chips, silicon carbide chips, and related modules in an effort to penetrate higher-end application markets.

Management stated that R&D investment is targeted to exceed RMB200 million in 2026, with a strategic focus on “green power + energy storage + computing power” applications. Key development areas include solid-state DC circuit breakers for data centers, as well as 2300V silicon carbide chips and modules. Against the backdrop of accelerating AI infrastructure expansion, upgrades to data center power systems are driving increased demand for high-voltage power devices, creating new market opportunities for related suppliers.

Flexible Power Transmission Orders Enter Monetization Phase

In its traditional core business, Sun.King Technology continues to maintain strong competitiveness in the flexible power transmission sector. In 2025, revenue from conventional DC and flexible DC transmission businesses reached RMB872 million, up 35% year-on-year. Growth was mainly driven by revenue recognition from domestic and overseas ultra-high-voltage (UHV) and flexible DC transmission projects, including the Saudi Central-Southern Region ±500kV flexible DC transmission project and the Gansu-Zhejiang ±800kV UHV transmission project.

Meanwhile, the company is also expanding into frontier sectors such as nuclear fusion, data centers, and electric vessels. Revenue from these emerging industries reached RMB114 million in 2025, representing a 72% year-on-year increase. Among them, the company’s pulse power switching products have already participated in several overseas nuclear fusion projects.
