“十五五”杭州电网投资建设规模引领全省

Core Viewpoint - During the "14th Five-Year Plan" period, Hangzhou's power grid will undergo significant expansion and upgrades to meet the increasing electricity demand and support the city's transition to a cleaner energy structure [1][2]. Group 1: Power Grid Expansion and Capacity - Hangzhou plans to construct 82 new and expand 10 existing substations of 110 kV and above, adding a total of 33 million kVA in transformer capacity, which is the largest scale in Zhejiang province [1]. - By 2030, the highest electricity load in Hangzhou is expected to reach approximately 34 million kW, with total electricity consumption exceeding 145 billion kWh [1]. - The new energy generation capacity is projected to reach 12 million kW, and new energy storage capacity is expected to exceed 2 million kW, with electricity accounting for about 45% of total energy consumption [1]. Group 2: Grid Development Strategy - The power grid will evolve into a "large hub" with plans for ultra-high voltage AC transmission and the fifth DC entry into Zhejiang, including the construction of 500 kV and 220 kV lines [2]. - The new grid structure will include 1,800 km of new 110 kV and above lines, with an expected main grid transformer capacity of around 150 million kVA by 2030 [2]. - The grid will adopt a "five sources, two belts, three rings" configuration to enhance its capacity and operational resilience [2]. Group 3: Supply Assurance and Service Upgrades - The supply assurance mechanism will focus on fine-tuning supply strategies, enhancing collaboration among government, electricity companies, and enterprises, and promoting the development of new energy storage [2]. - The goal is to achieve a demand response capability of over 5% of the maximum load, improving system regulation and emergency support capabilities [2]. - Supply services will be upgraded to ensure reliability, with a focus on creating a flexible and self-healing distribution network and enhancing lifecycle service systems for enterprises [2]. Group 4: Green Development Initiatives - The power grid will emphasize a new energy system, enhancing the integration and regulation capabilities for distributed renewable energy, new energy storage, and electric vehicles [3]. - Efforts will be made to build a carbon coordination system to support the construction of zero-carbon parks, factories, and villages, contributing to Hangzhou's goal of becoming a national pilot city for carbon peaking [3]. - The initiative will also include improving power supply in rural and remote areas to support the construction of a common prosperity demonstration zone [3].
