en.Wedoany.com Reported - A pre-coordination meeting for the units and auxiliary equipment of the Guigang Pumped Storage Power Station in Guangxi was held from June 1 to 3 at the Harbin Electric Machinery Company. The meeting announced that the project has officially transitioned into the hydraulic development and structural design phase for its units. This is the fourth pumped storage station invested by China Southern Power Grid Energy Storage in Guangxi and the first in western China to be located within a city. The station's units have a rated head of 421 meters, with plans to install four 300 MW pumped storage units, each operating at a speed of 428.6 revolutions per minute. The overall project is expected to be fully completed and commissioned by 2029.
During the meeting, the owner, design institute, and equipment manufacturer presented on the overall construction progress, design advancement, hydraulic development status, and project execution of the Guigang project. The parties conducted specialized group discussions on 146 agenda items across six areas: comprehensive technology, hydraulic design, pump-turbines, inlet valves, generator-motors, and contract project management. These discussions incorporated existing construction experience and standardization requirements. The pre-coordination meeting produced 88 meeting minutes and outlined the key tasks for each party in the next phase.
Li Dinglin, General Manager of China Southern Power Grid Energy Storage Company, put forward three work requirements during the summary meeting: First, strengthen the progress and quality control of the main equipment for the Guigang project from design to manufacturing to ensure the project proceeds as planned; second, both parties need to establish a standardized cooperation mechanism for pumped storage units to promote the continuous application and iterative upgrading of standardization outcomes; and third, increase collaboration in scientific research, focusing on technical areas such as large-capacity variable-speed units, wide-head variation units, and the retrofitting of aging units to support technological advancement in the industry.
Expert representatives from China Southern Power Grid Energy Storage Company and its affiliated construction management company, maintenance and testing company, and western maintenance and testing company, as well as from China Energy Engineering Group Guangxi Electric Power Design Institute, Harbin Electric Machinery Company, and specially invited industry experts jointly attended this pre-coordination meeting.
