The first underground power station in the complex. It was constructed in the early 70s by Yugoslav companies and European construction consortiums. The Francis runner turbines utilizing waters from the Thiba and Tana Rivers generate power at 11kV through three water-cooled generators. All the governors and excitation systems of the machines have recently been replaced with new ones. Electric power from Kamburu is conveyed to Nairobi via two 220kV transmission lines from a primary 132kV substation. Kamburu has a gated spillway capable of discharging 4,500 cubic meters of water. Water is conveyed to the next power station, Gitaru, via a 2.9km long tailrace tunnel.
