Chemal hydroelectric power plant, Hydroelectric power station in Chemalsky District, Russia.

The Chemal hydroelectric power plant is an electricity-generating facility along a river in the Altai region, operating with a capacity of about 0.5 megawatts. The installation harnesses the river's flow to produce electricity for the surrounding area.

The station was built in 1935 in the Altai Mountains by prisoners of SibULON, the Siberian Administration of Special-Purpose Camps; up to 700 prisoners worked on the site. It stood a few hundred metres from where the Chemal flows into the Katun and held two generators of 220 and 240 kW. After a 2011 accident flooded the machine hall it was taken out of service, and the 2014 flood washed away the earthen part of the right-bank dam.

The station is listed as a regional cultural heritage site. During the tourist season, guided tours are held inside the old station building, where visitors see the machinery used for electricity production. The guides describe how the plant was built in 1935 by prisoners of SibULON, the Siberian administration of special-purpose camps.

The station stands a few hundred metres from where the Chemal flows into the Katun. Tours of the building run only in the tourist season, so check availability before travelling. As of June 2025 the area around the dam is fenced off and repair work started in 2019 is still unfinished, so the structure itself can only be viewed from outside.

The station's two generators, rated 220 kW and 240 kW, kept total capacity under 460 kW. Up to 700 prisoners of the SibULON camp administration built it in 1935. The machine hall flooded in 2011, ending regular operation, and the 2014 flood washed away the earthen section of the right-bank dam.
