Eesti Küttejõud

AS Eesti Küttejõud (also: AS Eesti Kütte-Jõud; commonly: Küttejõud; literally: Estonian Heating Power) was an oil shale company located in Küttejõu, Estonia. The Küttejõu township, now district of Kiviõli, is named after the company.

Eesti Küttejõud was established in 1922 by the Union of Estonian Industrialists. It was as the first private oil shale mining company. In 1925, the Tallinn pulp factory Põhja paberi- ja puupapivabrik (Nordic Paper and Woodboard Mill) acquired the company. At the same year, the Küttejõu open-pit mine was opened. Unlike other that time oil shale companies in Estonia, it did not have any shale oil extraction but only mining operations. It sold mined oil shale directly for heating fuel to the paper mill and power plants.

In 1939, the company produced 126,238 tonnes of oil shale. After occupation of Estonia by the Soviet Union, the company was nationalized in 1940.
