央视网消息（新闻联播）：国庆中秋假期，万千建设者依旧在坚守岗位，一大批重大工程建设稳步推 进。 在广西北海，全球首台16兆瓦漂浮式海上风电成套系统示范应用工程项目——"三峡领航号"刚刚完成一 体化组装，投产后预计每年可以发出4465万度的清洁电能，能够满足2.4万户三口之家一年的生活用 电。在甘肃酒泉瓜州县，"双塔一机"光热储能电站今天（10月2日）完成最后调试，近27000块定日镜跟 踪太阳转动，将太阳光反射汇聚至两座吸热塔，实现高效集热。 这座光热储能电站与已投产的风电、光伏等多种能源联合调度，可实现24小时不间断供电，整个项目每 年可为电网提供18亿度清洁电能。 不仅是能源工程，这个国庆中秋假期，一批民生工程也按下了"快进键"。在山东济南，8条轨道交通线 路建设同步推进，2.6万余名建设者坚守岗位，确保项目早日通车惠及市民。在新疆天山胜利隧道，正 在加紧进行着洞口棚洞和地下通道的建设。与此同时，乌尉高速公路其他标段也正在开展路面摊铺以及 桥梁附属施工工作，为年底具备通车条件做最后冲刺。 假期期间，众多劳动者用自己的坚守和奋斗，保障着国家重大工程安全有序推进，一个个热火朝天的现 场也映照出发展建设的澎湃活 ...

Group 1: Infrastructure Development - The successful excavation of the Tongbaiyuan No.1 Tunnel, the longest tunnel of the Yan-Yu High-speed Railway, has reached 2000 meters, with a total length exceeding 14,000 meters. The railway will reduce travel time from Xi'an to Yulin from 5 hours to 2 hours upon completion [1] - The construction of the Luo-Ruo Railway, approximately 297 kilometers long, has begun track laying, which will enhance the "road-to-rail" transport capacity in Xinjiang by connecting with the Lanzhou-Xinjiang Railway and the Ge'ku Railway [2] - The Hefei-Wuhan section of the Yangtze River High-speed Railway has entered full construction phase, with the first steel truss beam of the Shi River Bridge successfully installed. The railway is expected to be completed by 2028 [3] Group 2: Renewable Energy Projects - The expansion of the Tianjin South 1000 kV UHV substation, a key project under the national "14th Five-Year Plan," has commenced operation, capable of transmitting over 40 billion kWh of electricity annually, enhancing the transmission capacity of clean energy from Inner Mongolia and Hebei to Tianjin [4] - The construction of the largest single-unit solar thermal storage project in China, the CGN Delingha 1 million kW solar thermal storage integrated project, has made progress with all heliostats installed and entering the equipment debugging phase. The project is expected to be operational by the end of this year, delivering 1.8 billion kWh of green electricity annually, equivalent to saving about 550,000 tons of standard coal and reducing carbon dioxide emissions by 1.3 million tons [4]
