The public tender for the reconstruction of excitation regulators for the Liptovská Mara, Domaša, Považská Bystrica, Ladce and Velké Kozmálovce hydroelectric power plants has ened. The winner is the company ZAT a.s. We have signed the contract with the representatives of Slovenská elektrárna, a.s. (SE) in early July 2021.
As part of the project, we will gradually reconstruct 11 generator excitation sets. The first - at the Považská Bystrica hydroelectric power plant - will be put into operation in December this year (TG2). The whole project will be completed by the reconstruction of the TG1 hydroelectric power plant Ladce in June 2023.
We have been cooperating with SE on the reconstruction of hydro and nuclear power plants for a long time. In the field of hydropower, for example, two years ago we reconstructed the generator excitation regulator at the Veľké Kozmálovce power plant, which provides a supply of cooling water for the Mochovce nuclear power plant. "Our control systems also run at other hydropower plants operated by the company, for example, we regulate turbines at the small hydroelectric power plant Ružín II or at the hydroelectric power plant Tvrdošín. As part of this contract, we will implement an excitation set control system consisting of ZAT AVR Z110 controllers at the hydropower plants,” adds Miroslav Košař, Strategist in the Hydropower Segment.
The company SE operates a total of 31 hydropower plants. Their total installed capacity is 1 653 MW, which is approximately 40% of the company's total installed capacity.
The contract in the amount of 15 million CZK for the reconstruction of excitation regulators for five hydropower plants in Slovakia once again confirmed the stable position of ZAT as a requested supplier in the field of construction and reconstruction of hydropower plants.
ZAT in hydropower
ZAT has been developing, manufacturing and supplying control systems in the field of hydropower for almost 40 years. We supply for both small hydropower plants and large hydropower plants with requirements for partial control solutions for individual operating files up to complex replacements and control of entire units and the implementation of a robust DCS system.
