Core Viewpoint - The Ningxia-Hunan ±800 kV UHVDC project has been launched, marking a significant step in utilizing renewable energy resources from Ningxia to support economic development in Hunan and surrounding regions [5][11]. Group 1: Project Overview - The project connects Ningxia's rich solar and wind energy resources to Hunan, serving as China's first UHVDC line primarily for transmitting renewable energy from a "desert" area [7]. - The project has a rated capacity of 8 million kW, capable of delivering 8 million kWh of electricity per hour at full power [7]. - The transmission distance reaches 1,616 kilometers, allowing electricity from Ningxia to cross six provinces [9]. Group 2: Environmental Impact - The project is designed to be environmentally friendly, with over 70% of the installed capacity coming from renewable energy sources and more than 50% of the electricity transmitted being renewable [11]. - It is expected to reduce carbon dioxide emissions by 16 million tons annually [11]. Group 3: Operational Performance - Since its commissioning in June, the project has maintained a high operational capacity, delivering over 3.5 billion kWh of electricity during peak summer loads in Hunan [13]. - The average power transmission has been nearly one-tenth of Hunan's total load, demonstrating its critical role in meeting regional energy demands [13].
