Energy company RWE confirmed the completion of the assembly of 100 wind turbines at the Sofia offshore wind farm. This project is located more than 200 kilometers off the British coast and represents one of the most extensive energy deployments in the region.
Wind Turbine Capacity and Power Supply
Regarding logistical timelines, the final turbine was installed on June 10, 2026. Currently, technical teams are focusing their efforts on mechanical testing and the subsequent commissioning of the high-voltage direct current (HVDC) system, an essential step prior to final connection to the electrical grid.
Regarding operational development, component transportation and assembly tasks began in March 2025. The process required the use of the Wind Peak jack-up construction vessel, a vessel owned by Cadeler and operated by Siemens Gamesa Renewable Energy (SGRE) that transported the structures in groups of six assemblies per voyage.
Furthermore, the dimensions of these 14 MW units constitute a large-scale structure. Each generator reaches a maximum height of 252 meters at its highest point, with 108-meter blades and a rotor diameter of 222 meters. Additionally, half of these devices incorporate recyclable blades manufactured by SGRE at its Green Port Hull facilities, located in British territory.
Through this technological configuration, the Sofia wind farm will reach a total capacity of 1.4 GW when fully operational. This installed capacity will supply clean electricity to approximately 1.2 million homes in the United Kingdom, consolidating the transition toward renewable sources.
