Sondu Miriu Power Station is situated in Kisumu County , 60km from Kisumu town and 350km from Nairobi. It draws water from the Sondu Miriu River whose main catchment area is Mau Forest. Sondu is a run-of-river scheme with an intake weir and holding pond that discharges the required water with a net head of 178m via a 6.2 km tunnel and a 1.2 km penstock to the vertical Francis turbines. Water from the turbines is discharged into an open outlet channel 4.7km long to the 21.2MW Sang’oro plant. Power generated is fed into the national grid through a 50km long 132kV transmission line into Mamboleo sub-station in Kisumu. There is a provision for an irrigation intake facility of about 2,380Ha of land in the Kano plains.
