History
editThe Sergeyevka Dam was commissioned in 1968 at the time of the Kazakh SSR. It had a hydroelectric power station with an installed power generation capacity of 2 MW. The hydroelectric power station building has a bottom spillway. The reservoir of the dam has a maximum storage capacity of 693,000,000 m3 (562,000 acre⋅ft) and a surface area of 117 km2 (45 sq mi). The Imanburlyq, a tributary of the Ishim River, has its mouth in the reservoir.[3]
Currently the power station has a capacity of 3.5 MW with two propeller turbines connected to VGSP 213/29-14 generators with a capacity of 1.23 MW each. The average annual electricity generation is 16 million kWh. The dam is owned by RSE "Kazvodkhoz", which manages 78 reservoirs in Kazakhstan.[1]
