Kislaya Guba Tidal Power Station, Tidal powered electricity generating station in the Kislaya Guba, Russia
Kislaya Guba Tidal Power Station is a facility in Murmansk Oblast that generates electricity from the movement of ocean tides. It consists of a simple earth dam about 20 meters long with one or two turbine generators that spin as water flows through the narrow bay during tidal cycles.
Built in 1968 during the Soviet era as a pilot project to test how tidal energy could work in cold northern waters, the station was shut down for about ten years before being restarted in 2004 with new turbines. It has since served as an experimental facility for studying renewable ocean energy in Russia.
The name 'Kislaya Guba' refers to 'Sour Bay', named after mineral-rich springs flowing into the water. Today, the site reflects Soviet-era ambitions to harness northern nature for modern purposes, visible in the simple structures built to work with tidal cycles.
The facility sits in a remote, cold region with extreme weather, especially in winter when ice and storms are common. Visitors should bring warm clothing and be prepared for difficult access, as few roads lead to this location in the Arctic region.
This is the only tidal power station of its kind in Russia and ranks as the fourth largest in the world, despite its modest appearance. Its construction used floating concrete blocks positioned by ships, an innovative method for the 1960s that remains of engineering interest today.
