Amid the global energy transition, the energy storage industry is experiencing explosive growth, becoming one of the most promising sectors in the new energy field. Since the start of 2026, as countries continue to accelerate green energy deployment, demand for energy storage has surged. Major Chinese storage companies are seeing orders stretch years ahead—from Sungrow's multi-region successes to BYD's large overseas contracts, and Formosa Smart Energy's backlog extending to 2030. This prosperity not only demonstrates the global competitiveness of China's energy storage industry but also directly drives upstream and downstream supply chains, including fasteners for storage equipment.

As global carbon reduction goals advance, renewable penetration rises, and AI infrastructure expands backup power needs, storage demand has exploded. In 2026, this trend has intensified, with Chinese storage companies reporting order backlogs covering Asia-Pacific, Europe, Africa, Latin America, the Middle East, and North America. Unlike traditional energy equipment, large-scale storage stations and industrial/commercial storage systems demand high structural stability, safety, and durability. Fasteners serve as the connecting backbone across battery compartments, module assembly, cabinet fixing, and grid connections, directly affecting equipment safety and lifespan.

Sungrow, a leader in storage, recently signed an agreement with South Africa's Herholdt's Group to deploy a 1,155 MWh industrial/commercial storage system. The company also signed a 100 MWh supply deal with Japan's Blue Sky Energy. In the UK, Sungrow supplied 136 battery units to the 150MW/300MWh Ferrybridge project—one of the UK's largest battery storage facilities. These large projects require high-strength, corrosion-resistant fasteners for battery module locking and cabinet assembly, with outdoor applications demanding enhanced vibration and dust resistance.

JinkoSolar Storage achieved a breakthrough in Latin America, partnering on a 1 GWh grid-side storage project using its SunTera G3 6.25MWh system. The system's high capacity and lifecycle optimization demand customized precision fasteners for long-term stability.

BYD Storage secured a major overseas order on March 27, signing a strategic agreement with Spain's Grenergy to supply 468 MC Cube-T storage units totaling 2.6 GWh for the Oasis solar-plus-storage project in central Chile. Mass production of BYD storage cabinets requires a mix of standardized and customized fasteners, particularly anti-loosening, corrosion-resistant types for battery compartment sealing and electrical component fixing.

Beyond industry leaders, emerging players are also performing strongly. CEEC Times New Energy signed a 2 GWh battery compartment supply contract for Oman. Sigenergy signed over 1 GWh in Africa within a week. Suzhou Times Energy Storage signed the world's first megawatt-scale anthraquinone flow battery supply agreement with Quino Energy. Sinohytec Storage secured its first distributed wind-solar storage project order. These projects expand fastener demand, with long-duration and wind-storage applications requiring new levels of temperature and fatigue resistance.

Formosa Smart Energy has the most striking order book—backlogged to 2030. Focused on LFP batteries, the company has built a full-chain capability from cells to system integration. Its backup power systems, designed for AI infrastructure, are expected to receive U.S. certification in Q3 this year. Mass production of its storage equipment creates massive demand for high-precision, anti-loosening fasteners, particularly for LFP battery module assembly under strict AI data center stability requirements. Formosa's markets already cover the U.S. and Vietnam, with further expansion into the Philippines and Poland this year, driving export demand for storage fasteners.

Storage battery packs, as core components, require high assembly precision, efficiency, and reliability. Fasteners and screw feeders play key roles in module locking and enclosure assembly. Unlike EV battery packs, storage packs prioritize heavy loads, long life, and low cost, with larger screws (M6–M10) and greater quantities under outdoor/industrial conditions. Higher standards for vibration resistance, dust protection, and maintainability require deep integration of fasteners with tightening systems for torque closed-loop and data traceability, pushing storage fasteners toward customization and high-end specifications.

Some fastener companies have already entered the storage赛道. Changhua Group received fixed-point orders from a top PV-storage customer in 2023 and achieved mass production by year-end, with anti-loosening performance ensuring reliable connections in PV-storage applications.

In summary, the energy storage industry is seeing robust development: leaders are setting direction, new players are breaking through, and order backlogs are full. This growth drives high-quality industry development and supply chain upgrading. For the fastener industry, the storage boom presents both a major opportunity and higher requirements. Traditional mid-to-low-end fasteners no longer meet the high-end demands of storage equipment, with high-precision, customized, and corrosion-resistant fasteners becoming mainstream.
