On Thursday, June 25, as part of the KLASTER project, two wind farms were officially opened in the West Pomeranian Voivodeship. The windmills are located between 3 and 13 km from the shoreline of the Baltic Sea. Elektromontaż Wschód, as the General Contractor, was responsible for the power sector.
Elektromontaż Wschód has designed and built a 30 km long 110 kV cable line from the Kamien Pomorski – RS Rybice – GPZ Skrobotowo with the RS Rybice network switching station and the extension of the Skrobotowo for the purposes of power evacuation from Rybice FW, Starza and Karnice II FW. The farms located in the districts of Kamień Pomorski and Gryfice include 33 turbines with a capacity of 2 MW each and 10 turbines with a capacity of 2.2 MW each. The connection capacity of both farms is 88 MW, and the total installed capacity is 97.18 MW. The total lifetime is 25 years. The capital expenditure on this project amounted to PLN 543 million. The cost of 1MW of installed capacity is PLN 6.1 million.
The construction phase started in the first quarter of 2019 and was completed in the first quarter of 2020.
In total, 43 windmills, with the estimated annual production of 275 GWh of energy, will meet the energy needs of about 120,000 households. During the opening of the West Pomeranian investment, Jacek Sasin, the Deputy Prime Minister and Minister of State Assets said that “this is as much as a city the size of Lublin consumes in a year”. In addition, the implementation of the Klaster project is to enable the avoidance of emissions at the level of about 215,000 tons of CO2.
The construction of the 110 kV cable line connected the existing Main Power Supply Point (GPZ) located in Kamień Pomorski (owned by Enea Operator S.A.) with the newly built Rybice Network Switchgear (RS) and further with the existing Skrobotowo substation. The line runs through urban areas, crosses the national road, poviat and commune roads, passes through two drillings under the river, and then leads through floodplains.
16,340 m³ of concrete (over 1,800 courses of concrete trucks) and 2,120 tons of reinforcing steel (more than the weight of 8 Boeing 787 Dreamliners) were used to build the foundations of all windmills. The turbines, each weighing approximately 260 tons, were installed on 110 and 125 meter towers, respectively. The blades working on them, made of laminate (a mixture of glass fibre and resin), have a diameter of 100 or 110 meters in length.
PGE CEO Wojciech Dąbrowski added that “the wind farms opened on Thursday are the largest investment in wind farms in Poland”.
