How does the Chitral Hydel Power Station generate electricity?

The Chitral Hydel Power Station generates electricity through a run-of-river hydroelectric configuration, relying on the natural flow of the Lutkho river rather than a large reservoir for storage. The process begins with the diversion of water from the river's main channel. According to technical descriptions of the facility, the flow of the Lutkho river is diverted by a channel that is 3.72 km long. The length of the channel and the gradient of the terrain create the necessary head, or pressure difference, to drive the turbines.

Once the water reaches the power station, it passes through the turbine units to convert hydraulic energy into mechanical energy. The station is equipped with four distinct turbine-generator units. The operation of these turbines depends on the consistent flow of water through the 3.72 km diversion channel, making the station's output somewhat variable depending on the seasonal flow of the Lutkho river.

After passing through the turbines, the water is typically discharged back into the river system downstream of the power station, completing the run-of-river cycle. The electricity generated by the four units is then stepped up and transmitted to the local grid. This transmission infrastructure ensures that the 1 MW of generated power reaches the consumers in the city efficiently. The entire system, from the diversion channel to the transmission line, has been operational since the project was commissioned in 1975, under the operation of the Water & Power Development Authority.
