The Sofia project will be located 195 kilometers off the northeast coast of the United Kingdom. The 100 SG 14-222 DD wind turbines will be distributed over an area of 593 square kilometers, similar to that of the island of Ibiza. According to Siemens Gamesa's estimates, once commissioned, Sofia will be capable of generating enough electricity to meet the demand of more than 1.2 million British households. Almost half a hundred of the Siemens Gamesa turbines that will integrate Sofia (44 to be precise) will be equipped with RecyclableBlade blades. This is the first time that the German manufacturer has applied its recyclable technology to blades of this size, 108 meters long.
Siemens Gamesa installed its first recyclable blades in the German Kaskasi project, also developed by RWE, in the summer of 2022. The eight-megawatt Kaskasi wind turbines (model SG 8.0-167 DD) have 81-meter-long blades. Sofia's blades will be 27 meters longer than Kaskasi's.
Marc Becker, CEO of Siemens Gamesa's offshore business: "When we started working with RWE on the Kaskasi project, we knew that we had taken the first steps towards a decisive turnaround in the wind industry. Having the opportunity to produce and install 132 recyclable blades for the Sofia project is an extraordinary achievement. It demonstrates our companies' joint focus on delivering even greater levels of sustainability in renewable energy generation globally."
Siemens Gamesa's wind turbine blades are made from resin-bonded materials resulting in a lightweight and highly resistant structure. RecyclableBlade technology allows the blade materials to be efficiently separated at the end of their useful life and reused in new applications after separation.
The blades will be manufactured at the Hull (UK) plant, where the first recyclable blades were also produced for the Kaskasi offshore wind project.
