In a festive atmosphere, in the presence of representatives of the political leadership, the region, the local government and executives of the energy sector, an event was held on Thursday for the completion of the first Repowering project in Greece on 9 Aegean islands. The event was welcomed by Mrs. R. Savvaki, Senior Economic Policy Officer on behalf of the ambassador of the Netherlands, Mr. S. Terstal, Mr. S. Oikonomou, President of KAPE, Mr. K. Mavros, Director Advisor to PPC Renewables, Mr. C. Kok, Managing Director of EWT and Mr. D. Karagoules, General Manager of RESINVEST. The event was coordinated by the journalist Ms. M. Nikoltsiou.
EWT, through a public open tender, undertook, on behalf of PPC Renewables, the design, supply, transport, installation, commissioning and maintenance of 10 Wind Farms with a total of 22 Wind Turbines with a total power of 19.8MW on 9 Aegean islands, specifically in Evia, Ikaria, Karpathos, Psara, Lesvos Limnos, Samos, Chios and Mykonos, while the Greek group RESINVEST undertook as the main contractor the project management for the transportation and erection of the wind turbines. The infrastructure projects were awarded to the Electromec-Nostira joint venture in collaboration with RESINVEST.
The contractors built all 10 wind farms at the same time, with active construction sites on all the islands, despite the numerous difficulties they faced. Among the important successes of the project are the implementation of a particularly demanding and technically complex solution for the transport of the equipment to Melanio, Chios, through seawalling, for which a temporary ramp of 36 meters was built into the sea. Also, special management of the Wind Turbines had to be carried out in the Petrified Forest in Sigri, Lesvos, as a total of 650 findings were found in 3 foundations where they were transferred with special care and diligence to the Petrified Forest Museum in a specially designed exhibition space. Finally, the timely completion of the project was a challenge due to the unfavorable situation of lack of important materials for the construction of the interconnection networks, machines and personnel due to the successive lockdowns.
Despite the difficulties, EWT and RESINVEST managed to manage all the issues that arose and currently 22 EWT Wind Turbines are in operation and generate more than 54,000 MWh per year, while at the same time contributing to the reduction of carbon dioxide emissions by approximately 15,500 tons per year. Their good operation has been ensured through a 14-year maintenance contract.
Environmental management of the desiccated equipment was carried out on all the islands. Also, according to the current institutional framework, they were transferred to special management centers. Finally, for the first time all infrastructure projects are certified in terms of their construction quality by an independent body (BoP Certification).
The aim of Repowering is to make better use of the already installed equipment, the energy potential and the latest technology, which through modern wind turbines offer greater energy efficiency and better results.
In his speech, Mr. Black said “the completion of the first wind farm renovation in our country demonstrates the company’s determination and paves the way for a new market, that of Repowering.”
Mr. Dimitris Karagoules after initially describing the successful completion of a completely complex parallel construction project of 10 A.P. which were also the first repowering project of such extent in Greece, he then emphasized the urgent need to immediately take measures to support and encourage repowering in Greece, which could meet the ESEK goals by themselves, without essentially additional environmental impacts. Finally, he asked for the updating of the National Energy Planning with the aim of fully exploiting the country’s potential in the production of energy from RES, with the aim of Greece becoming a key exporter of green energy in the next decade.
Mr. Carel KokCEO of EWT said in his speech “as a newcomer to EWT, I am completely satisfied to see the excellent teamwork, the technical training of the people, the ability to overcome problems and the excellent cooperation. I am proud of everything we have achieved together and I am convinced that our wind turbines together with our new Class IA model, , are perfectly designed to meet the challenges and the ambitious plan for Repowering the Aegean”.
