History
The development of the Kakanj Thermal Power Plant was deeply intertwined with the local coal mining industry, which had been active in the region since 1898 (per historical records of the Kakanj basin). This long-standing resource availability provided the foundational fuel supply necessary for the thermal station's eventual construction and sustained operation.
Construction of the power plant officially commenced in 1947, marking the beginning of a multi-decade engineering project that would significantly shape the energy infrastructure of Bosnia and Herzegovine. The first unit was commissioned in 1956, initiating electricity generation for the region. This initial phase was followed by the addition of a second unit in 1960, which helped to stabilize output and expand the plant's reach.
Expansion and Finalization
The expansion of the Kakanj Power Station was a prolonged effort spanning 28 years. This extended timeline reflects the gradual integration of new technology and the scaling of capacity to meet growing regional demand. The final phase of this major expansion concluded with the commissioning of the seventh unit in 1988. This completion marked the culmination of the primary construction era, establishing the plant's configuration that would support its role as one of the country's largest coal-fired facilities.

Technical Specifications
The Kakanj Thermal Power Plant operates as a significant baseload facility within Bosnia and Herzegovina's energy infrastructure. The station is classified as a coal-fired power plant, utilizing coal as its primary fuel source to generate electricity for the national grid. The facility is operated by Elektroprivreda Bosne i Hercegovine, the principal electric power company in the region. The plant has been in continuous operation since its initial commissioning in 1956, establishing it as one of the oldest and most enduring thermal energy assets in the former Yugoslavia.
Installed Capacity and Output
This figure represents the nominal output capability of the plant's turbine-generators under standard operating conditions. In terms of annual production, the facility generates approximately 2.3 billion kilowatt-hours (kWh) of electricity per year. This output level underscores the plant's role in meeting a substantial portion of the country's domestic electricity demand. While some external references may cite varying capacity figures, such as 578 MW, the authoritative operational data from the operator and primary energy records consistently identify the installed capacity at 450 MW. The 2.3 billion kWh annual production figure provides a practical measure of the plant's contribution to the grid, reflecting both the installed capacity and the operational availability factor over a typical year.
Infrastructure and Stack
The height of the stack is critical for the efficient dispersion of flue gases and particulate matter, minimizing local air quality impacts from the coal combustion process. The 300-metre chimney serves not only a functional aerodynamic purpose but also acts as a visual landmark in the Kakanj region. The structural integrity and height of the stack reflect the engineering standards applied during the plant's development and subsequent expansions throughout its operational history.
What are the plans for future expansion?
Planned Capacity Additions
The Kakanj Thermal Power Plant, currently operating with an installed electric capacity of 450 MW, is subject to expansion plans aimed at modernizing its output and replacing older infrastructure. According to the provided grounding, there are specific proposals to introduce a new 300-MW steam unit to the facility. This addition represents a significant increase in the plant's thermal generation capabilities, building upon the existing operational framework managed by Elektroprivreda Bosne i Hercegovine.
In parallel with the steam unit expansion, plans include the potential integration of a 100-MW Combined Cycle Gas Turbine (CCGT) block. The introduction of a CCGT unit suggests a strategic move towards diversifying the fuel mix or improving thermal efficiency through gas-fired generation, complementing the primary coal-fired operations that currently produce around 2.3 billion kWh of electricity per year. This 100-MW addition would further enhance the plant's flexibility and output potential within the Bosnian energy grid.
Replacement of Older Sets
These expansion and modernization efforts are partly driven by the need to replace older, less efficient generating sets. Specifically, the plans target the replacement of old 32-MW sets that are currently part of the Kakanj Power Plant's infrastructure. The removal of these 32-MW units is a key component of the modernization strategy, allowing for the integration of larger, more efficient technologies such as the proposed 300-MW steam unit and the 100-MW CCGT block.
The transition from multiple smaller 32-MW sets to larger, modern units like the 300-MW steam generator and the 100-MW CCGT block is expected to optimize the plant's operational efficiency. This modernization aligns with broader trends in energy infrastructure where aging thermal plants are upgraded to maintain reliability and output levels. The Kakanj Power Plant, with its 300-metre tall chimney—one of the tallest man-made objects in former Yugoslavia—remains a critical asset in Bosnia and Herzegovina's energy sector, and these planned upgrades aim to secure its continued operational status and relevance.
