In July 2026, the State Council of China officially included new energy storage in the six emerging pillar industries, specifying that the industry scale would exceed 10 trillion yuan by 2030. This policy signal marks the formal leap of the energy storage industry from "supporting and subordinate" to "strategic core," opening an unprecedented window of growth for the upstream electronics manufacturing industry chain.
Policy Turning Point: The Beginning of the Era of Independent Energy Storage
For the past few years, the energy storage industry has been unable to escape the policy shackles of "mandatory energy storage allocation"-companies were forced to allocate energy storage to obtain approval for new energy projects, driving up project costs, diluting investment returns, and trapping the industry in a vicious cycle of low-price competition.
Starting in 2025, this predicament will see a fundamental reversal. The mandatory energy storage allocation requirement for new energy will be abolished, and an independent energy storage capacity pricing mechanism will be officially implemented. The energy storage profit model will upgrade from a single peak-valley arbitrage to a triple revenue combination of "capacity compensation + electricity trading + ancillary services." 2026 is widely recognized in the industry as the "Year One of Independent Self-Sustaining Development" for energy storage, marking the industry's official departure from policy dependence and its transition to a new stage of market-oriented and large-scale development.
Meanwhile, the "Standards for Judging Major Power Accident Hazards and Regulations for Supervision and Management," which officially came into effect in July, significantly raised the industry's entry threshold. The grid-connected performance of energy storage power stations-including high and low voltage ride-through capabilities, voltage control capabilities, and dynamic reactive power support capabilities-was incorporated into statutory safety standards. Energy storage projects that do not meet compliant grid-connected performance requirements are all deemed major hazards. The establishment of this regulatory red line will accelerate the elimination of low-end capacity and drive industry competition back to the level of technology and quality.
Market Opportunities: A Blue Ocean Driven by Triple Demand
Policy easing is only the starting point. The real driver of the explosive growth in the energy storage sector is the convergence of demand from the power system, computing infrastructure, and overseas markets.
From the power system perspective, the supply-demand imbalance caused by the large-scale grid connection of new energy sources is becoming increasingly prominent, and the grid's demand for energy storage for peak shaving and frequency regulation continues to grow rigidly. Twenty-four provinces across China have specified energy storage capacity targets in their 15th Five-Year Plan for Energy, with a total planned capacity of 280GW. Inner Mongolia has the highest target (60GW), followed by Hebei (35GW) and Henan (23GW).
From the perspective of computing infrastructure, data center energy storage capacity has increased by over 70% year-on-year, making AIDC energy storage a necessity. The International Energy Agency predicts that by 2030, global computing power consumption will account for more than 3% of total electricity consumption, and the compound annual growth rate of domestic computing power consumption will exceed 40% between 2026 and 2030. Energy storage is no longer just a "stabilizer" for the power system, but also the "energy foundation" of the computing power era.
From the perspective of overseas markets, European energy storage cell shipments surged by 421% year-on-year in the first quarter, and the full-year energy storage capacity forecast for the United States has been revised upward to 49.8GWh. Gross profit margins in overseas markets are significantly higher than in the domestic market, and leading energy storage companies have made overseas expansion a core source of performance elasticity this year.
Technological Transformation: New Requirements for PCB/PCBA Companies
The energy storage industry is shifting from extensive growth to intensive operation, placing higher demands on the performance and reliability of upstream electronic components. Taking the Battery Management System (BMS), the "nerve center" of an energy storage system, as an example, its main control board needs to handle high-precision data acquisition, complex algorithm calculations, and multi-node communication, imposing stringent standards on the number of PCB layers, wiring density, and impedance control.
Currently, energy storage BMS main control boards generally adopt a 10-12 layer HDI design, combined with laser blind via technology, to achieve a balance between high-density wiring and high-speed signal transmission. Energy Management System (EMS) core boards and energy storage converter (PCS) control boards also have rigid requirements for multilayer construction, high precision, and impedance consistency; some products already require high-multilayer board processes with 16 or more layers.
It is worth noting that the trend towards higher voltage is reshaping the technological roadmap for energy storage PCBs. The voltage levels of energy storage systems have evolved from the early 1000V to 1500V, placing higher demands on the voltage withstand rating and CTI (Critical Tracking Index) of the high-voltage isolation boards. Simultaneously, the thermal design of energy storage systems is becoming increasingly complex, significantly increasing the demand for metal substrates and thick copper heat sinks.
Tighter industry regulations have also impacted PCB quality control. The stringent requirements for grid-connected energy storage performance in July mean that the reliability verification cycle for energy storage electronic control systems will be significantly extended. PCB manufacturers wishing to enter the energy storage supply chain must establish a comprehensive quality control system covering design review, process control, finished product testing, and reliability verification, rather than simply relying on low prices for volume.
Entry into the Market: Strategic Choices for PCB Companies
Facing the strategic energy storage market, PCB/PCBA companies need to undergo a systematic upgrade across three dimensions: technological capabilities, supply chain qualifications, and service models.
In terms of technological capabilities, companies should prioritize developing high-multilayer PCB (2-16 layers) and HDI process capabilities, along with specialized processes such as impedance control, buried resistors and capacitors, and rigid-flexible integration, to meet the technical requirements of core control modules like BMS, EMS, and PCS in energy storage. Simultaneously, the development of heat dissipation-related processes such as metal substrates and thick copper plates is also essential.
Regarding supply chain qualifications, as a new type of power infrastructure, end-users have high requirements for supplier certifications in energy storage. Overseas markets require international certifications such as UL, CE, TUV, and VDE, while the domestic market has specific requirements for IATF 16949 automotive-grade quality control and ISO three-system certification. PCB companies with overseas export compliance experience will have a first-mover advantage in the global energy storage market.
In terms of service models, energy storage projects are generally characterized by long R&D cycles, rapid iteration, and high certification requirements. Companies providing one-stop PCB+SMT+PCBA services can offer energy storage customers a complete chain from design review and rapid prototyping to mass delivery, significantly reducing the complexity of their supply chain management. A 48-hour rapid quotation and rapid prototyping response capability, coupled with DFM pre-review services, helps customers avoid manufacturability issues in the early design stage and shorten product introduction cycles.
Regarding quality assurance, the cost of failure in energy storage electronic systems is high-at best, it can damage project revenue; at worst, it can trigger safety red lines. Establishing a four-level quality control system covering incoming material inspection, process control, finished product full testing, and reliability verification, coupled with 100% FCT functional testing, is essential to winning the trust of energy storage customers.
Conclusion
The launch of the trillion-dollar energy storage market is not a fleeting speculative fad, but a long-term industrial opportunity driven by three factors: policy and mechanism reforms, mature technological routes, and increasing market demand. In this process, PCBs, as the core carrier of energy storage electronic control systems, are seeing their technical thresholds and quality requirements pushed to new heights.
For prepared companies, the current energy storage boom is not an entry ticket, but the starting gun for a survival of the fittest.
