Viru Keemia Grupp (VKG) is an Estonian holding group of oil shale industry, power generation, and public utility companies.


VKG's two main areas of operations are shale oil extraction, and electricity and heat production and distribution.

Shale oil production[edit]

The subsidiary producing shale oil is VKG Oil. The company utilizes two different processes: Kiviter and Galoter.[2][3][4][5] The company also tested but rejected the Alberta Taciuk Process.[6] In total, VKG Oil processes 2 million tons of oil shale per year, producing 250,000 tons of shale oil.

The company operates several Kiviter retorts, the largest of them having a processing capacity of 40 tonnes per hour of oil shale feedstock.[7][8] In December 2009, VKG Oil opened a new Galoter retort called Petroter.[5][9] Engineering of the retort was done by Atomenergoproject of Saint Petersburg; engineering of the condensation and distillation plant was done by Rintekno of Finland.[10] The plant has a processing capacity of 1.1 million tonnes of oil shale per year and it produces 100,000 tonnes of shale oil, 30 million cubic metres (1.1×10^9 cu ft) of oil shale gas, and 150 GWh of steam per year.[5] The company started construction of the second Petroter plant in 2012 and plans to build also the third plant.[11][12]

In 2008, the company received a permit for developing the Boltysh oil shale deposit in Ukraine.[13]

Power generation and distribution[edit]

VKG's subsidiary VKG Energia, a power and heat generation company, was established in 2004 after VKG bought the Kohtla-Järve Power Plant and the Kohtla-Järve heat distribution system from Kohtla-Järve Soojus.[14] In 2005, it bought another power plant in Kohtla-Järve from Fortum Termest.[15] In 2006, VKG bought a 40,8% stake in Kohtla-Järve Soojus, an operator of the Ahtme Power Plant, and in 2010 it took a full control of the company, now VKG Soojus.[16][17] All generations capacities were transferred to VKG Energia while VKG Soojus is responsible for heat distribution.[17][18] All generations capacities were transferred to VKG Energia while VKG Soojus is responsible for heat distribution.[17] VKG Energia has installed electrical capacity of 80 MW and heat capacity of 700 MW.[19]

In July 2006, VKG acquired Narva Elektrivõrk, the second largest power distribution company in Estonia,[20] and renamed it VKG Elektrivõrgud.[21][22][23]

Other activities[edit]

In April 2011, VKG acquired assets of a bankrupt company Silbet Plokk that manufactured cinder blocks for construction from oil shale burning residue.[1][24][25] The company was renamed VKG Plokk.[25]
