Recently, China’s first grid-forming wind-solar-storage integrated system applied for real-time power supply at substations—the Houhai San (Chunhui Station) demonstration project—was successfully commissioned. This marks a significant breakthrough in China for the integrated application of grid-forming energy storage technology and urban distribution networks. In this landmark project, Haihong Electric’s 3D Wound Core dry-type transformer technology provided solid technical support for the system.

Strengthening the Nation through Maritime Development. On China's journey towards becoming a maritime power, the high-quality development of the marine economy is of paramount importance. Haihong Electric actively participates in this endeavor, contributing to the nation's marine economic development with its outstanding green power distribution solutions.

Driven by the "Dual Carbon" goals, the energy revolution is in full swing today, and the integrated development of transportation and energy has become a crucial pathway for building green transportation. Responding to national strategic needs with technological innovation, Haihong Electric has partnered with Guangdong Provincial Transportation Development Co., Ltd. to jointly develop the Super-Grade 1 Energy Efficiency Amorphous Alloy Prefabricated Substation. This product has been deployed at the Guangdong Hengpi PV-Storage-Charging Super Charging Station and contributed to the station's recognition with an Excellent rating in the "Transportation Engineering Group" of the 2025 Guangdong Provincial Highway Micro-Innovation Achievements, setting a benchmark for integrated PV-storage-charging construction in highway transportation sectors across the province and nationwide.

With the successful grid connection of the Fukuoka City energy storage power plant to Japan's electrical grid, Haihong Electric has added another benchmark project in the overseas new energy sector. This is not only first 2MW/8MWh energy storage power station in Fukuoka but also Haihong Electric's first prefabricated substation project for energy storage in overseas markets, winning international recognition with China's cutting-edge technology.

Against the backdrop of accelerating the comprehensive green transformation of economic and social development, the low-carbon retrofitting and construction of thermal power plants has become an industry trend. Leveraging its self-developed Fully Insulated Low-Temperature-Rise 3D Wound Core energy-saving technology, patented cooling system technology, and live-line fan replacement technology, Haihong Electric has provided safe and highly reliable low-carbon power distribution solutions for multiple thermal power plants, assisting them in achieving low-carbon transformation and ensuring safe, continuous operation.

With urban development, power upgrades in old urban areas face numerous challenges: difficult site selection, long construction cycles, unstable power distribution quality, and resident concerns about equipment safety and noise. The Miniaturized Double-layer Prefabricated Substation launched by Haihong Electric, with its outstanding advantages of small footprint, high safety, and reliability, is becoming a "powerful assistant" in the power equipment renovation of old urban areas, providing efficient and convenient solutions for the transformation and upgrading of urban power distribution equipment.
