Core Viewpoint - The successful operation of the 750 kV AC system at the Zhongning Converter Station marks a significant milestone in the commissioning of China's first desert and Gobi renewable energy transmission corridor, facilitating the delivery of green electricity from Ningxia to Hunan [1][2]. Group 1: Project Overview - The Ningxia to Hunan ±800 kV UHVDC project is a key initiative under the national "14th Five-Year" electricity development plan, with the Zhongning Converter Station serving as the sending end [2]. - Upon completion, the project is expected to deliver 36 billion kWh of green electricity annually to Hunan, with over 50% coming from renewable sources, significantly reducing CO2 emissions by over 16 million tons each year [2]. Group 2: Operational Details - The 750 kV AC system, completed on May 10, 2023, serves as a critical link for power conversion and networking within the UHV project, ensuring stable operation for future developments [1]. - The project will commence the energization testing of the bipolar low-end converter on June 1, 2023, and aims to officially start electricity delivery to Hunan by mid-June [2]. Group 3: Impact on Energy Supply - The project is anticipated to increase Hunan's electricity supply by approximately one-sixth, addressing the bottleneck of local renewable energy consumption in Ningxia and enhancing the power supply security for Hunan [2]. - The successful integration of this "green energy artery" will bolster Ningxia's grid capacity for external electricity transmission to 20 million kW, contributing to the establishment of a new energy system [2].
