江苏今年首个500千伏电网重点工程投运

Core Viewpoint - The successful operation of the 500 kV power grid project associated with the expansion of the Guodian Investment Binhai 2×1 million kW unit marks a significant advancement in Jiangsu's energy infrastructure, ensuring stable electricity supply during peak winter demand [1]. Group 1: Project Overview - The Guodian Investment Binhai power plant expansion project includes the addition of two 1 million kW coal-fired generating units, expected to generate 10 billion kWh annually, sufficient to meet the electricity needs of approximately 4 million households for a year [1]. - The newly constructed power grid project features a total length of 89.045 kilometers, connecting the Binhai power plant to the Heqi 500 kV substation, enhancing regional electricity supply capacity [1]. Group 2: Industry Context - Jiangsu's new energy capacity has rapidly developed, with the Yancheng new energy grid capacity reaching 20.34 million kW, making it the first city in the Yangtze River Delta to exceed 20 million kW in new energy grid capacity [1]. - The construction of the power grid project is part of Jiangsu's efforts to build a new power system and optimize its energy structure, providing essential support for the efficient integration and delivery of renewable energy sources like wind power [1]. Group 3: Challenges and Innovations - The project faced significant challenges due to complex geological conditions and the need to cross highways, railways, and multiple transmission lines, leading to high coordination difficulties and construction risks [2]. - Innovative use of drones for precise surveying and the development of tailored plans for each crossing were implemented to ensure efficient construction and successful project operation [2]. Group 4: Future Developments - Additional major grid projects, such as the Huaneng Tongzhou Bay power plant and the Yancheng Gaorong 500 kV transmission and transformation project, are under construction, which will further enhance Jiangsu's electricity supply capacity and support winter power safety [2].
