A hydro-solar complementary project in Zambia -- the Lusenga Solar PV Project, constructed by PowerChina -- has recently been connected to the grid.
Located in Central Province, Zambia, the project includes a 27 MW PV plant, a substation that steps up voltage from 33 kV to 66 kV, and two 66 kV transmission lines of approximately one kilometer each.
The project operates in conjunction with an existing hydropower station, using a "solar priority, hydro regulation" model. During the day, the solar farm generates power while the hydropower station stores water; at night and on cloudy days, hydropower supplements the supply. This creates an efficient hydro-solar complementary system and improves power supply quality.
Once fully operational, the project will provide stable clean energy to the local grid, effectively boost local power supply capacity, and help optimize Zambia's national energy mix, playing a significant role in promoting renewable energy development.
