The Chinese company Shanghai Electric has commissioned Uzbekistan’s first digital substation, the Zafarabad Substation, with a voltage of 220 kV. The facility is located in the Jizzakh Region, as reported by PR Newswire, citing a press release from the Chinese corporation.
The main objective of the substation, which occupies an area of approximately 75,000 square meters, is to significantly improve the power supply in the Jizzakh Region and surrounding areas. The Zafarabad Substation will have a capacity of 400 megawatts, which will double the supply of electricity to households and businesses. This will help solve the issue of heating homes, a problem local residents face in winter due to shortages of natural gas and electricity. Now, they will no longer have to rely on outdated stoves and makeshift heating methods.
The digital substation is equipped with two 250 MW autotransformers, which will reduce the voltage in the network from 220 kV to 110 kV for more efficient load distribution. However, the key feature of the project is the fully automated control system, which greatly enhances the efficiency and safety of the facility’s operation. Additionally, Zafarabad is equipped with advanced monitoring and data collection systems, effectively eliminating the need for manual intervention. For example, in the event of an accident, the equipment will quickly identify the fault and adjust the load on the network to prevent power supply disruptions.
The project to build Uzbekistan’s first digital substation began in 2021 and was financed by the Asian Development Bank. At that time, it was also clarified that the Shanghai Electric company won the turnkey construction contract through a tender.
