Generator 6 of the Šoštanj Thermal Power Plant (TEŠ)
is operating again after the completion of the scheduled maintenance works,
which were carried out during the Christmas and New Year holidays. It was
synchronised with the Slovenian electricity network this morning. The generator
had been off-line since 16 December, when it was shut down due to the collapse
of the walling material of one of the high-pressure oil feed pipes on the
hydraulic cylinder of the high-pressure relief valve on the boiler. The repair
works cost around EUR 25,000.
The TEŠ maintenance workers first replaced the damaged
parts, and then continued with the scheduled maintenance works. These were scheduled
in the annual plan for between 21 December 2018 and 3 January 2019. The
maintenance works included the installation of additional water drainage
systems on some of the boiler collectors, replacement of worn-out pipes on the
re-heating pipeline 1, repair of drives of high-pressure station valves and
other regular maintenance works.
In 2018, Generator 6 produced a total of 2,865,901 MWh
of electricity, which is 0.47% more than the planned production. It operated
for 270 days. It was off-line for 83 days for scheduled maintenance works and
for an additional 12 days because of extraordinary events.
While Generator 6 was off-line, the supply of the
Šalek Valley with heating energy was provided by Generator 5 and the
