On 13 March, Power Unit No. 1 was the first unit that was removed out of service for scheduled intermediate maintenance. The works will last until 31 May and include repairs of the boiler with replacement of CSE tubes, transformer, generator, and turbine. Standard current repairs of Power Unit No. 2 are combined in terms of deadlines with Unit No. 1 to make it possible to repair Chimney No. 1 (gas ducts, reinforced concrete slabs).
Power Unit 3 is subject to major overhaul this year, which will last four months. Partial replacement of boiler gas ducts, replacement of feed-water economizer, industrial safety inspection of technical devices, replacement of 40 elbows of live steam and hot reheat pipelines will be done. During the overhaul of Power Unit 3, scheduled current repairs of Power Unit No. 4 will be carried out. During the same period, an industrial safety inspection of the second chimney stack will also take place.
A month and a half (from 11 November until the end of the year) is scheduled for the minor inspection of Power Unit No. 5 (CCGT-448).
