中新网湖北荆门9月23日电 (何俊辉 李翊嘉 余哲)1000千伏荆门特高压站三号主变扩建工程22日开工,这是湖北省“十五五”规划首个开工的特高压扩建项目,标志着荆门站从我国首条特高压交流试验示范工程的“终点站”,迈向华中电网“能源中枢”新阶段。工程计划于2027年10月建成投运,将新增一组3000兆伏安主变压器。
荆门特高压站是我国首条商业化运行的特高压交流工程——晋东南至南阳至荆门工程的末端站点。2022年底,随着华中“日”字形特高压交流环网逐步建成,该站战略定位发生历史性转变:不再是单一结构的输电终端站,而是升级为衔接华北电网与华中各省的环网核心枢纽站,承担水火互济、错峰调峰、新能源消纳和跨省电力交易等多重功能。
“前几次扩建主要是‘接线路’,把荆门站跟更多地方连起来。这次不一样,这次是‘强心脏’。”国网湖北中超公司1000千伏荆门特高压站副站长杨冰介绍,新增主变容量后,荆门站潮流调节能力将大幅提升,“河南富余电力可以往湖北送,湖北用电高峰时可以从华北调,新能源大发时消纳得掉,负荷尖峰时顶得住。它从一座变电站变成了区域电力能源中枢。”
本期扩建工程将新增一组3000兆伏安主变压器及相关低压配套装置,不仅增加容量,更实现功能跃升,将有效应对华中地区电力跨省互济需求增强、新能源大规模接入及市场化跨省跨区电力交易提速等新挑战。
国网湖北中超公司项目管理一部主任唐正森表示,荆门站扩建与金沙江—湖北、陕北—湖北两条“外电入鄂”特高压直流通道,以及华中特高压交流环网其余节点共同构成一体化能源网架。
据介绍,该工程预计2027年10月竣工投运。届时,1000千伏荆门特高压站潮流调节能力将大幅增强,华中特高压网架布局进一步完善,风光水火多能互补的资源优化配置平台加速成型,三峡近区电源送出瓶颈有望打通。

Italy's Senate approved legislation to pave the way for a return to nuclear power, clearing the upper house 81-51 with seven abstentions. The bill establishes a legal framework for next-generation nuclear technologies and authorizes the government to draft implementing decrees over the next 12 months on reactor licensing, safety standards, waste management, and site criteria. It marks a major step in Premier Giorgia Meloni's drive to bolster energy security and meet climate goals, despite new reactor construction still being years away.
On September 23, the Zhejiang Ocean Clean Energy Industry and Technology Docking and Exchange Event was held in Wenzhou, and the "Zhejiang Province Ocean Clean Energy Industry Development Guidelines" were released on site. The "Guidelines" put forward Zhejiang's goal of exceeding 300 billion yuan in scale of the province's marine clean energy and equipment industry by 2030.

The Greater Bay Area Hydrogen Energy Comprehensive Application Pilot City Group held a work deployment meeting in Guangzhou. The urban agglomeration consists of 11 cities. It plans to promote 16,000 hydrogen fuel cell vehicles, build 100 hydrogen refueling stations, and build four cross-provincial hydrogen energy transportation corridors during the four-year pilot period to promote the large-scale application of the hydrogen energy industry.

Saudi Arabia's East-West oil pipeline has restarted operations after being attacked by drones, and crude oil export operations at Yanbu Port on the Red Sea coast are expected to gradually resume on the 22nd. The pipeline is currently moving at lower rates and full recovery may take weeks.
State Grid Sichuan Electric Power Company announced on the 22nd that the first section of the Panxi UHV AC project in Sichuan was successfully completed. The project spans multiple high-voltage transmission lines and uses mechanized tower assembly and parallel construction techniques. It is expected to be completed in 2028 and will significantly enhance Sichuan's clean energy transmission capabilities.

The Xinjiang Production and Construction Corps promotes the "medicine-light complementation" model on the southern edge of the Gurbantunggut Desert, using the space under photovoltaic panels to plant mugwort and other traditional Chinese medicines. This model not only increases the land output value, but also improves the ecological environment through vegetation and sand fixation, achieving a deep integration of new energy and specialty agriculture.
