谋划储备“六张网”项目116个 大冶“网”联未来生活Planning and reserving 116 projects for the 'six networks'; Daye's 'networks' connect future life

Since the beginning of this year, Daye City has seized the policy opportunities presented by the construction of the “six networks,” focusing on areas such as the new power grid, computing power network, and next-generation communication network. Guided by major projects, the city is accelerating the development of a modern infrastructure system that is deeply interconnected and mutually empowering. As of now, the city has planned and reserved 116 projects related to the “six networks.”

In the autumnal land of the Copper Capital, green electricity flowing from the snowy plateau streams along the ultra-high-voltage silver lines, hydrogen-powered buses traverse streets rich in Bronze Age culture, and data streams of tens of gigabit optical networks shuttle through industrial parks. Among the 116 projects, there are both the Liangzihu area drainage projects and the Daye City Green Hydrogen Factory Nanshi Branch green power direct connection projects. These interwoven networks are connecting the present with the future.

Integrating green electricity into the grid is the first move in Daye's construction of the "six networks." At the Daye (Yongxing) converter station, clean electricity from Ganzi in Sichuan and Changdu in Tibet is being transmitted through ultra-high-voltage lines, spanning thousands of mountains and rivers to converge here. On December 18, 2025, China's first ultra-high-voltage direct current transmission project reaching deep into the Sichuan-Tibet Plateau—the Jinshang-Hubei ±800 kV ultra-high-voltage direct current transmission project—was completed and put into operation. As the core terminal hub of the project, the Daye (Yongxing) converter station successfully received clean electricity from Sichuan and Tibet.

This ultra-high-voltage direct current project innovatively adopts the 'addressed cascade' technology, splitting the sending-end converter station into the Bangguo Converter Station in Ganzi, Sichuan at an altitude of 2,980 meters and the Kamae Converter Station in Chamdo, Tibet at an altitude of 3,720 meters, overcoming high-altitude insulation challenges through series voltage division, and achieving multi-energy complementarity of hydropower, wind, and solar. As Hubei Province's second 'external power import' channel, the project, once operational, can transmit about 40 billion kilowatt-hours of clean electricity annually, equivalent to replacing about 12 million tons of standard coal and reducing carbon dioxide emissions by about 30 million tons, roughly equal to planting 120 million trees. With the full operation of the project, the power supply reliability in cities such as Wuhan, Huangshi, and Ezhou will increase by more than 30%.

The integration of green electricity into the grid brings more than just ecological benefits. For Daye, the annual input of hundreds of millions of kilowatt-hours of green electricity into the local power grid will effectively promote the optimization of the regional energy structure, assist in the green transformation of traditional industries such as steel and building materials, and attract emerging industries such as hydrogen energy and intelligent manufacturing, forming an investment promotion advantage of 'electricity-driven projects.'

Green electricity has arrived, but how can it be used effectively? Daye's choice is to look to hydrogen energy for the future. At the Smart Information Center of the Hydrogen Energy Innovation and Technology Park in Daye Lake High-Tech Zone, huge electronic screens display dynamic data, showing the entire hydrogen energy 'production, storage, refueling, and usage' chain at a glance, including photovoltaic power generation, the purity of electrolytic hydrogen, real-time pressure at hydrogen refueling stations, and the operation trajectory of hydrogen-powered buses. In Songwan Village, Jinhu Street, the mountains of abandoned mines are covered with photovoltaic panels. This photovoltaic power plant, transformed from abandoned mines, has a total installed capacity of 20 megawatts and is expected to generate 20 million kilowatt-hours annually, with the green electricity directly supplied to the nearby Jiangqiao hydrogen production plant.

At the Jiangqiao hydrogen production plant, both alkaline water electrolysis and proton exchange membrane electrolysis technologies are operating simultaneously, producing 1,500 tons of high-purity green hydrogen annually, with a purity of 99.999%. In Nanshi Village, Handiqiao Town, the second hydrogen production plant has begun to take shape, using a "grid + distributed photovoltaic + energy storage" power supply model, with an annual hydrogen output of over 3,000 tons. After the two plants are linked, the city's total hydrogen production capacity will reach 12,200 standard cubic meters per hour, with green hydrogen prioritizing local hydrogen-powered public buses, logistics trucks, and mining heavy trucks, and the surplus stably supplied to the Wuhan metropolitan area. On the storage side, the country's first rock cavern hydrogen storage project has been established in Daye; on the hydrogen refueling side, comprehensive energy stations such as Daye East and Olympic Avenue are already in operation, and the Jinshandian hydrogen refueling station is about to be put into operation.

The new power grid and computing power network are like the 'Ren and Du meridians' in the 'six-network' system. In April this year, the Ministry of Industry and Information Technology announced the completion of the 10-Gigabit optical network pilot project, and the 10-Gigabit campus pilot in the Daye Lake High-tech Zone Electronic Information Industry Park successfully passed the acceptance check. The deployment of the 10-Gigabit optical network means that enterprises in the park can enjoy ultra-high-speed, low-latency network experiences, providing a network foundation for applications such as cloud computing, industrial optical quality inspection, artificial intelligence plus ultra-high-definition video surveillance, and model training and inference, as well as laying an information highway for 'Daye Intelligent Manufacturing.'

Surging from the Copper Capital, the 'network' connects the future. As the construction of the 'six networks' advances in depth, Daye is promoting industrial development through infrastructure 'hard connectivity' and achieving 'strong coordination,' accelerating in the race toward green transformation and intelligent manufacturing upgrades.
