Breakdown in the first tunnel — Trepça gives details: the repair process has been hampered by a lack of spare parts in the warehouse

Trepça today provided additional information about the breakdown that occurred at the Tunnel Transformer Station, as a result of which the electricity supply to the Trepça Flotation Mine in Stan Tërg and the Flotation Unit was cut off.

The statement said the repair process has been hampered by a lack of spare parts in the warehouse.

Announcing that the miners had reached the surface, Trepça said 54 miners came up via the emergency stairs, while the remaining 9 miners stayed in the mine until the electricity supply was restored.

Read Trepça’s full statement on the breakdown at the First Tunnel Transformer Station:

On 07.10.2026 at 19:30, a breakdown occurred at the Tunnel Transformer Station, namely in the 35 kV system, as a result of which the electricity supply to the Trepça Flotation Mine in Stan Tërg and the Flotation Unit was cut off.

At the time of the breakdown, there were a total of 63 miners in the mine, who were on the second shift, scheduled to end at 23:00.

After the power cut:

– 54 miners reached the surface via the emergency stairs;

– the remaining 9 miners stayed in the mine until the electricity supply was restored.

The electricity supply to the Trepça Flotation Mine in Stan Tërg was restored at 02:30, while the remaining 9 miners reached the surface at 02:50.

After power was restored, the first shift began work normally in the mine.

Meanwhile, the Flotation Unit has remained out of operation due to damage caused by the breakdown in the 35 kV transformer.

Technical teams are working to repair the breakdown, including checking and replacing five (5) 6.3 kV protective fuses, as well as other relevant elements of the electrical installation.

The repair process has been hampered by the lack of spare parts in the warehouse, as these parts are not currently in stock.

After the repairs are completed and all technical and safety checks are carried out, the electricity supply will be fully restored and the Flotation Unit put back into operation.

We remain committed with all our means, sparing nothing of what we know and can do, to return the situation to normal. You will be informed in due time about further developments and the completion of the repair, as Telegrafi reports.
