Technical Specifications

The Bobov Dol Power Plant operates as a conventional coal-fired facility within the Bulgarian energy infrastructure. Located in the administrative territory of Golemo Selo, near the town of Bobov Dol in Kyustendil Province, the station has been in continuous operation since its initial commissioning in 1973. The plant serves as a key baseload generator for the regional grid, utilizing hard coal reserves from the surrounding basin to produce electricity. While specific operational metrics such as thermal efficiency or annual output fluctuate with market demand and fuel quality, the installed capacity remains the primary technical indicator of the plant’s output potential.

Installed Capacity and Output Variance

The officially recognized installed capacity of the Bobov Dol Power Plant is 630 MW. This figure represents the total electrical output potential under standard operating conditions. In various energy reports and historical records, the capacity is sometimes cited as 570 MW. This discrepancy typically arises from the distinction between gross capacity (total generation at the turbine shaft) and net capacity (generation delivered to the grid after deducting auxiliary power consumption), or from temporary derating during maintenance cycles. For the purpose of technical profiling, the 630 MW figure is the authoritative specification provided in primary sources. The plant’s status remains operational, contributing to the stability of the Bulgarian power system.

Mechanical and Structural Configuration

The mechanical heart of the plant consists of steam turbine generators driven by high-pressure steam produced in boilers fueled by pulverized coal. Although the specific manufacturer or model of the turbines is not detailed in the primary grounding sources, the configuration is consistent with mid-20th-century European coal plant designs. The plant utilizes a conventional Rankine cycle, where water is heated in boilers, expanded through turbines to generate electricity, and condensed back into water in condensers. The chimney structure is a prominent feature of the plant’s silhouette, standing at a height of 200 metres. This elevation is critical for the dispersion of flue gases, minimizing local air pollution impacts on the nearby village of Golemo Selo and the town of Bobov Dol.
