MAINTENANCE WORKS CONCLUDED, GENERATOR 6 IN OPERATION AGAIN

4. 1. 2019

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 gas-powered generator.
