超千亿投资推进电网建设

Core Viewpoint - The construction of the Liaoning power grid is a key initiative during the "14th Five-Year Plan" period, aimed at enhancing energy supply and supporting industrial transformation in the region [1][2]. Group 1: Infrastructure Development - The "14th Five-Year Plan" emphasizes the construction of a robust power grid, with over 100 personnel working on the 500 kV Liaobin transmission and transformation project [1]. - National Grid Corporation of China has invested over 100 billion yuan in Liaoning since the beginning of the "14th Five-Year Plan," marking a historical high in investment [1]. - The completion of 10 new 500 kV substations has significantly improved Liaoning's power supply capacity, increasing from 40 million kW in 2020 to a projected 50 million kW by 2025 [2]. Group 2: Technological Innovation - Liaoning's power grid has integrated 16 types of original technology achievements, achieving full domestic production across the supply chain [2]. - The province has successfully implemented the world's first large-capacity black start test for a city grid, enhancing the resilience of the power system under extreme conditions [2]. - Innovative technologies such as the first domestic 66 kV static synchronous compensator and the first 10 kV superconducting fault current limiter have been introduced [2]. Group 3: Service Improvement - The smart distribution network has stabilized voltage levels, allowing for consistent power supply even during peak demand periods [3]. - The "Three Zero" service initiative has benefited 491,000 users, saving a total of 6.384 billion yuan in electricity costs [3]. - Continuous improvements in power supply services have enhanced user satisfaction and contributed to the overall development of the region [3].
