On January 30, China Energy Engineering Group Jiangsu Electric Power Construction Company No.1 and Xinjiang Refining & Chemical Construction Group Co., Ltd. formed a consortium that won the bid for the PC contract related to the photovoltaic molten salt energy storage demonstration project at the thermal power plant of Dushanbe Petrochemical Company. The project is located in Dushanzi District, Karamay City, Xinjiang Uygur Autonomous Region. Jiangsu Power Construction No.1 Company is responsible for constructing a centralized photovoltaic power plant with a capacity of 195 megawatts (on the DC side)/150 megawatts (on the AC side), as well as a molten salt energy storage system capable of generating steam at 150 megawatts/480 megawatt-hours (including a grid coordination system). It also involves the renovation of a 10-megawatt backpressure turbine at the Dushanzi Petrochemical Thermal Power Plant. The work includes construction in various fields such as architecture, structure, equipment, processes, electrical systems, instrumentation, and general layout and vertical planning. Once completed, the Dushanzi Petrochemical Thermal Power Plant will use green electricity along with molten salt energy storage to generate steam on an annual basis, thereby replacing some of the steam produced by coal-fired boilers. This approach will help reduce carbon dioxide emissions, increase the proportion of green electricity used and the level of electricalization at the end-use stage, and facilitate a reduction in both the total amount of petrochemical energy consumed and its intensity. It will also create room for further reductions in carbon emissions, contributing to the local community’s achievement of its \"dual carbon\" goals.
