The Kohtla-Järve Power Plant (Estonian: Kohtla-Järve soojuselektrijaam) is an oil shale-fired power plant in Kohtla-Järve, Estonia. It is owned by VKG Soojus, a subsidiary of Viru Keemia Grupp.

The Kohtla-Järve Power Plant was commissioned in 1949–1967 with designed electrical capacity 48 MW.[1] The first generator of the plant was commissioned in January 1949. This was the first time when the oil shale pulverized-firing combustion technology was implemented for power generation.[2] The first generator had a capacity of 12 MW.[3] At the beginning the plant used Riley Stoker boilers and General Electric generators; however, boilers developed for the pulverized firing of coal and lignite were not fit to work on pulverized oil shale.[3][4]

As of 2005, the power plant had capacity of 39 MW electricity and 534 MW of heat.[5][6] It is equipped by five stream generators and two hot water boilers (Barnaul BKZ-75-39F middle-pressure boilers. Its four turbines are manufactured by Fraser and Chalmers, Kirov Plant, Lang-Ganz, and Bryansk Turbine Works.[7]

In addition, an oil shale gas-fired plant was built next to existing plant. This plant is equipped with Energomash manufactured boilers and Kaluga Turbine Works manufactured turbines.[8]
