Abstract: The purpose of the integral refurbishment of old power plants is to bring the power plants into a condition that will enable them to work for the next 30 or 40 years without needing new expenditure. At the same time, a refurbished power plant has to produce more energy, operate automatically and require less maintenance work. A case study of such an integral refurbishment of the ex-mine power plant is presented in the article. A two-unit power plant was refurbished after 55 years of uninterrupted operation. The first unit was totally exchanged with a new one. On the second machine, a new runner was developed and other mechanical equipment was renovated. Also, on both units, new governors were built, and a full automatic system was created.
