December the 6th, 2022 - The well known Croatian company Koncar is an internationally recognised leader, and it has been working intensively on the creation of new or the revitalisation of old energy plants for around 100 years now. The revitalisation of a plant in Greece is now in the works.
As Poslovni Dnevnik/Darko Bicak writes, in very few segments of the global market does Croatia occupy such a large share as it does in the energy sector, especially in terms of transformers and hydropower plants.
The biggest name in this field is undoubtedly Koncar, which has been working on new or revitalising existing energy capacities for about 100 years, and the latest example of this is over in Greece. To speak more specifically, Koncar recently signed a contract with the Greek electricity company (Public Power Corporation - PPC) in the capital of Athens for the first phase of the revitalisation of the Messochora hydroelectric plant in Greece.
The first phase of the works
Several Koncar Group companies, led by Inzenjering/Engineering (KET), will participate in this Greek revitalisation project. As part of the first phase of the revitalisation of this plant, the testing and analysis of all of the equipment at the hydroelectric power plant will be carried out, and all of the preparatory work will be done for the first commissioning of this plant.
As explained by Gordan Kolak, the president of the Koncar Management Board, the HE Messochora project was initially contracted in the years following the end of the Homeland War, back during a period when the Koncar Group was working very intensively to return to its former markets, which included that of nearby Greece.
"We won't be exaggerating by saying that this particular project was particularly crucial for Inzenjering, but also for other companies from within the wider Koncar Group," said Kolak. It regards a plant with an installed capacity of 2x90 MW, the equipping of which (with all kinds of electromechanical equipment) was contracted by Koncar back in 1996 amid strong international competition on a "turnkey" basis.
The implementation of the project lasted from 1996 to 2002, with Koncar successfully fulfilling all of its contractual obligations, and the equipment was delivered and installed within the given deadlines. However, PPC faced certain administrative problems due to which it could not fill the reservoir with the water required for testing, and ultimately ensure the operation of this plant.
Therefore, in agreement with PPC, the equipment was finally taken over and preserved so that the project could continue when the conditions for it were properly created. Few expected that this would happen only after a twenty whole years, after Koncar, following several months of negotiations with PPC, finally signed the contract by which it returned to this Greek hydroelectric plant.
"Taking into account the attitude of our Greek partner who wants to put this plant into operation with as much originally produced equipment as possible, it's evident that this is an extremely large technological and engineering challenge, because in the meantime, several technological changes have taken place on the market for many types of installed equipment, which is typical for the passage of this amount of time. Therefore, members of Koncar's teams from the original phase of the plant's construction will participate in the work on the ''new'' Messochora. These kinds of challenges are at the very core of Koncar's expertise, performance according to special customer requirements and the adaptation of equipment and systems of different generations,'' said the Zagreb-based company.
To date, Koncar has secured references in as many as 130 markets around the world and delivered more than 400,000 transformers of various types, voltage levels and powers, fully or partially built and revitalised tens of thousands of transformer plants up to 400 kV, as well as 400 hydroelectric power plants, and produced revitalised about 700 generators.
The production of hydrogen generators in their facilities began back in 1947, and the first one was put into operation the following year at the HPP Mariborski otok, which operated successfully for more than forty years.
By 1957, 100 generators had been delivered, and in that very year, the first export job in Pakistan was achieved by Koncar for HE Chichoki Mallian. Their biggest turnkey project took place in 1988, when they delivered equipment for the 295 MW Bechme HPP in Iraq.
