Construction activity is ramping up at the steam supply station of CNNC HuiNeng’s 1.6GW clean energy support project in Jinta County, Gansu province, as engineering teams push ahead with schedule, quality, and coordination targets. On site, works including rebar installation and concrete pouring are progressing in parallel, reflecting a rapid transition into the next phase of delivery.
Located within the Jinta Nuclear Technology Industrial Park, the project represents a total investment of RMB 830 million and covers an area of approximately 10 hectares. It is a key component of Gansu’s third batch of large-scale clean energy base developments. The project is designed to establish an advanced “power–heat–storage” conversion and integration system, combining multiple energy sources into a unified framework.
Core infrastructure includes a 440MW electric steam boiler system, three 25MW molten salt electric heaters, and a 2,000MWht molten salt thermal energy storage system. Together, these systems will enable integrated “wind–solar–storage–heat” coupling, enhancing energy flexibility and providing stable, dispatchable thermal supply to support industrial demand in the region.
The project has now entered a critical phase, marked by the final stages of civil construction and the commencement of equipment installation. Civil works are underway across five main process buildings and three auxiliary facilities, with earthworks and concrete pouring nearing completion.
Key equipment is arriving on site in sequence. Five electric steam boilers have been delivered, with the first unit successfully hoisted into position on March 16. Installation of the remaining units is progressing as planned. This milestone signals the project’s transition from civil engineering to mechanical and process installation, as construction shifts from below-ground to above-ground works.
According to project timelines, the main structures are expected to be topped out by June 30, grid connection conditions achieved by July 20, and steam supply readiness reached by September 30.
