TPP Kakanj

The construction of the Thermal Power Plant was carried out in stages, in the period from 1947 to 1988.

Installed capacity: 450 MW (without Units 1,2,3 and 4)

Estimated annual electricity generation: 2,003,157 GWh 

 Electricity generation began in 1956, with the commissioning of Units 1 and 2. The increase in the installed capacity of TPP "Kakanj" follows with the construction and commissioning of other generation units:


  • In 1956, Unit 1 (capacity of 32 MW) - decommissioned
  • In 1956, Unit 2 (capacity of 32 MW) - decommissioned
  • In 1960, Unit 3 (capacity of 32 MW) - decommissioned
  • In 1960, Unit 4 (capacity of 32 MW) - decommissioned  
  • In 1969, Unit 5 (capacity of 110 MW) 
  • In 1977, Unit 6 (capacity of 110 MW)
  • In 1988, Unit 7 (capacity of 230 MW)

Units 1, 2, 3 and 4 are permanently decommissioned. Electricity is produced by TPP "Kakanj" in Thermoblocks 5, 6 and 7. 

In the post-war period, the following was carried out: 

  • Reconstruction and modernization of Units 5 and 6 (110 MW),
  • Partial reconstruction of Unit 7 (230 MW) and cooling system of Units 5 and 6 – transition from semi-open to closed cooling system.

The realization of these investments extended the production life of the plant by 15 years, improved operational readiness, increased the degree of usefulness and reduced emissions of pollutants.

In addition to the electricity generation for the purposes of the EES, the TPP "Kakanj" produces and delivers:

  • Thermal power for district heating of the city of Kakanj,
  • Slag and ash to the Cement Factory "Kakanj".

The Thermal Power Plant "Kakanj" is located on the left bank of the river Bosna, five kilometres upstream of the town of Kakanj, in the Central Bosnian coal basin, which has significant geological reserves of brown coal.
