南方电网持续提升海南电网基础设施建设和电力支撑保障水平

Core Viewpoint - Southern Power Grid plays a crucial role in the construction of Hainan Free Trade Port, marking a significant upgrade in Hainan's power grid with the launch of the 500 kV main network, enhancing the region's energy supply capabilities and supporting the clean energy island initiative [1][3]. Group 1: Infrastructure Development - The 500 kV main network project connects 14 cities and counties in Hainan, achieving a maximum transmission capacity exceeding 3.5 million kW, which is four times that of the previous 220 kV lines [3]. - The project is designed to withstand severe weather conditions, adhering to the highest standards for typhoon resistance, thereby significantly improving disaster resilience [3][5]. - Southern Power Grid has invested a total of 46.5 billion yuan over the past eight years to enhance power supply security and disaster resistance in Hainan, with plans to invest an additional 46 billion yuan during the 14th Five-Year Plan period [1][4]. Group 2: Energy Transition and Future Plans - By 2025, Hainan's clean energy installed capacity is expected to reach 87.1%, with clean energy generation accounting for 73.03% of total power generation, positioning Hainan as a leader in energy transition [4]. - The province aims to achieve a total installed capacity of 48.95 million kW by the end of 2030, with renewable energy sources like wind and solar expected to account for 55% of this capacity [4]. - Southern Power Grid plans to enhance interconnection with Guangdong and develop a flexible power exchange project, which will increase power supply reliability and system resilience by 50% [3][5]. Group 3: Strategic Goals and Support for Development - Hainan's strategic goals include becoming a clean energy island and a demonstration province for new power systems by 2030, with a focus on a power supply system primarily based on renewable energy [4]. - The energy infrastructure is being developed to support the rapid growth in electricity demand, projected to reach 88 billion kWh by the end of the 14th Five-Year Plan, with an annual growth rate of 10.3% [3][4]. - Southern Power Grid is committed to building a robust digital power grid that integrates large-scale offshore wind power and distributed energy resources, ensuring energy security for Hainan's development [5].
