海南能源大动脉实现飞跃 支撑海岛“五向图强”

Core Viewpoint - The commissioning of the 500 kV main grid project in Hainan marks a significant leap in the province's power grid capabilities, supporting the "Five Directions to Strengthen" strategy and the construction of a clean energy island [1][2]. Group 1: Investment and Development - Since the launch of the Hainan Free Trade Port in 2018, China Southern Power Grid Company has invested a total of 46.5 billion RMB in Hainan's power grid development [2]. - During the 14th Five-Year Plan period (2026-2030), an additional investment of 46 billion RMB is planned to upgrade the Hainan power grid, focusing on enhancing interconnection with Guangdong, power supply security, and disaster resilience [2]. Group 2: Infrastructure and Capacity - The newly operational 500 kV main grid features an innovative "口" shaped topology connecting 14 cities and counties, with a maximum transmission capacity exceeding 3.5 million kW, which is over four times the capacity of the previous 220 kV lines [3]. - The project has been optimized for disaster resistance, meeting the requirements for protection against once-in-a-century typhoons, significantly enhancing its disaster resilience [3]. Group 3: Clean Energy Goals - Hainan aims to establish a clean energy island by 2030, with a power supply system primarily based on renewable energy, supported by nuclear and thermal power [3]. - By November 2025, the proportion of clean energy installed capacity in Hainan is expected to reach 87.1%, with the generation share at 73.03%. By the end of 2030, the total installed capacity is projected to reach 48.95 million kW, with renewable energy accounting for 55% of the installed capacity and 30% of the generation [3]. Group 4: Future Outlook - China Southern Power Grid Company plans to strengthen the main grid in Hainan, coordinating the large-scale development of coastal nuclear and offshore wind power, thereby enhancing the reliability of power supply across the island [5].
