The Lusemfwa 27 MWp/20MWac PV Project in Zambia, constructed by SINOHYDRO, was connected to the grid and began generating power on May 31.

 Located in Zambia's Central Province, the project included a 27 MW solar PV plant, a 33 kV to 66 kV step-up substation, and two 66 kV transmission lines spanning approximately 1 kilometer.

 Integrated with an existing hydropower plant, the project utilizes a "solar-priority, hydro-regulated" operational model. During the day, the solar plant generates power while the hydropower station stores water and energy; at night and on overcast days, the hydropower facility supplements the power supply. This creates an efficient, complementary hydro-solar system that enhances the reliability and quality of the local power supply.

 During construction, the project team optimized the layout of the PV modules through meticulous design. They also overcame challenges posed by changes in mountain elevation, rugged terrain, and complex shading conditions within the plant area.

 As a result, the design ensures unobstructed sunlight across the plant from 9:00 am to 3:00 pm, while minimizing shading, even under extreme conditions like the winter solstice.

 Furthermore, through zoned and streamlined construction, centralized pre-assembly, and rapid installation methods using adjustable pile caps, the team compressed the construction cycle per megawatt from eight days to five days, shortening the overall construction timeline by nearly 30 percent.

 As Zambia's first hydro-solar complementary project, its grid connection stands as a prime model and a benchmark demonstration, providing a valuable case study for Zambia as it explores the integrated development of traditional hydropower and new energy.
