In the second half of May and the first half of June, visitors to the upper reservoir of the Dlouhé stráně pumped storage plant will have the unusual opportunity to watch a unique technological operation in which a specialist company will coat the slopes of the reservoir with a special material with a UV filter. The so-called mastix will protect the area exposed to extreme weather conditions from ultraviolet radiation from the hot summer sun and from winter frosts. The work is part of this year's more than 400 million investment, which will ensure safe operation of the plant in the years to come.
