At the Jinta Multi-Energy Complementary Plant in the Baishuiquan Solar Industrial Zone, rows of photovoltaic panels continuously harvest sunlight. A towering concentrating-solar-power (CSP) receiver stands like a giant on the Gobi while the molten-salt energy-storage system operates at high efficiency, feeding green electricity into the grid around the clock.
The Jinta plant is one of the second-batch of national “solar-plus” demonstration projects built in desert, Gobi and wasteland (“Sha-ge-huang”) areas. It innovatively couples CSP and PV technologies, enabling efficient synergy and deep integration between different forms of energy. The heliostat field covers roughly 770,000 m²; through self-developed, high-precision smart heliostats and a field-control system, the plant achieves long-distance, high-accuracy tracking and large-scale mirror-field control, markedly raising overall intelligence. The facility has now entered full and stable power-generation operation.
Huang Lushan, deputy manager of the Jinta Multi-Energy Complementary Plant, said:
“The 600-MW PV section was grid-connected on 27 March this year, and the 100-MW CSP section on 28 May. Total designed investment is RMB 4.2 billion. After commissioning, the plant is expected to deliver about 1.45 billion kWh of electricity to the grid annually—equivalent to saving 480,000 t of standard coal and cutting 1.36 million t of CO₂ emissions.”
Maintenance crews have intensified inspections, increased equipment patrol frequency, and adopted cooling measures to keep operating temperatures down, ensuring stable operation.
“We carry out blanket hidden-danger checks on inverters, cable joints and other equipment using infrared thermometry, making sure every component is in good condition,” said Li Depeng, safety officer of the Jinta Multi-Energy Complementary Plant.
