After 74 days of continuous operation since the previous shut-down, Unit 6 of the Šoštanj Thermal Power Plant (TEŠ) was shut down late in the evening. The reason for the controlled shut-down is suspicion of boiler leakage. During the shut-down, which is expected to take five days, the regenerative air pre-heater will be partially cleaned and the suspected leakage in the boiler piping will be traced.
Until yesterday, Unit 6 produced 2,675,887 MWh of electricity and 216,362 MWh of heat for the Šalek Valley this year. Altogether, this year the TEŠ has produced 3,120,309 MWh of electricity and 250,687 MWh of heat.
In the first ten months of the year, the availability of Unit 6 was 98.76%, which is an excellent result in terms of reliability of operation in comparison with European fossil fuel power plants, placing it near the top in Europe.
During the shut-down of Unit 6, the production of electricity and heat will be secured with the operation of Unit 5 and gas-fired power plants, if necessary.
