The Zhongning Converter Station, a ±800 kV converter station located in Zhongning, Ningxia, serves as the starting point for the Ningxia-Hunan High Voltage Direct Current (HVDC) Transmission Project. This extensive project covers an area of 501.6 acres and marks the "Ningdian Ru Xiang" initiative, which is the first domestic HVDC transmission corridor primarily focused on developing a large solar photovoltaic base in the desert. It aims to facilitate the transmission of renewable energy, with 50% of the energy being clean power.The project has attracted an investment of approximately 100 billion yuan and features a total line length of 1,619 kilometers, traversing six provinces: Ningxia, Gansu, Shaanxi, Chongqing, Hubei, and Hunan. About 242 kilometers of this line are located in Ningxia. Official approval for the project was granted on May 24, 2023, and a mobilization meeting was held via video link simultaneously in Hunan and the Ningxia Hui Autonomous Region on June 11, 2023.

Once completed and commissioned in 2025, the project is expected to consolidate clean energy from various regions in Ningxia, increasing the outward transmission capacity of the Ningxia power grid from 140 billion kWh to 220 billion kWh. The installed capacity for renewable energy is anticipated to exceed 50 million kW, effectively addressing the challenges of integrating and utilizing new energy in central and southern Ningxia. Annually, the project aims to transmit approximately 36 to 40 billion kWh of electricity to Hunan, significantly increasing Hunan's electricity load by over one-sixth.

The energy dynamics in Ningxia are set to achieve substantial milestones, targeting an "internal supply" and "external delivery" of 100 billion kWh each, meaning that the sales volume within the region and the outgoing power volume will reach this goal. Furthermore, the development of renewable energy aims for a "dual 50%" objective, where installed capacity constitutes 50% and power generation accounts for 50% of the total electricity consumption in the region.

TEEE has successfully secured contracts for three packages related to both the Zhongning and Hengyang converter stations, which include a total of 189 sets of dry-type air-core reactors. The project is making rapid progress, with our reactor products already delivered to the site, where our after-sales service personnel are providing installation guidance at the station.
