The Guohua Ruitai Photovoltaic Power Station, operated by the National Energy Group, is located in Shangshawo Town, Jingtai County, Baiyin City. An aerial view reveals a vast expanse of solar panels resembling an ocean. At the beginning of the new year, reporters visited the station's main control room, where staff monitored fluctuating numbers on computer screens and frequently communicated with grid dispatchers via telephone to coordinate power generation parameters.
Duty Supervisor Fan Jinrong pointed to the power data on the screen and explained that the grid dispatch department had issued a total active power command of 36 megawatts for the entire station, equivalent to a generation capacity of 36,000 kilowatts. Under ideal conditions, this translates to 36,000 kilowatt-hours of electricity generated per hour, representing approximately one-tenth of the station's total installed capacity of 350,000 kilowatts.
When asked why such a large facility was operating at only ten percent of its capacity, Fan Jinrong clarified, "Our station was connected to the grid on November 25 last year and is currently undergoing a three-month grid integration testing phase. This phase primarily assesses equipment performance and safety protocols between the power station and the grid. During this period, the station operates at about 10% of its output capacity. Once testing is complete, full-scale generation will commence. During midday hours with ample sunlight, the station will generate 350,000 kilowatt-hours of electricity per hour."
Regarding the destination of the electricity after full operation, Fan Jinrong detailed, "We are a supporting new energy project for the 'Gansu Power to Shandong' initiative in Baiyin. Once the station operates at full capacity, the electricity will be transmitted sequentially through the 330-kilovolt Ruitai Substation, the 750-kilovolt Qinchuan Substation, and then connected to the Qingyang Converter Station. From there, it will feed into the 'Gansu Power to Shandong' transmission line, directly supplying Shandong. Ultimately, the power will be distributed throughout Shandong and the broader East China region via the Shandong power grid."
Zhang Siqun, a specialist from the Development and Planning Department of the State Grid Baiyin Power Supply Company, provided further context. The Baiyin supporting new energy projects for the 'Gansu Power to Shandong' initiative total 4.5 gigawatts. Annually, they are expected to transmit approximately 8 billion kilowatt-hours of green electricity to the load centers in East China. This output is equivalent to saving 990,000 tons of standard coal and reducing carbon dioxide emissions by 6.33 million tons.
To ensure the full grid integration of these 4.5-gigawatt new energy projects in Baiyin, the Baiyin Power Supply Company has successfully established a seamless connection between the new energy facilities and the ultra-high voltage main grid. This achievement has helped construct a complete energy industry chain characterized by "resource development in the west, centralized transmission via the power grid, and terminal consumption in the east."
