When completed, the prototype unit is going to be the world’s most powerful wind turbine, surpassing GE’s 13 MW Haliade-X prototype, which is now functioning in Port of Rotterdam, situated in the Netherlands. The SG 14-222 DD turbine has a 14 MW capacity, which may be increased to 15 MW utilizing the company’s Power Boost feature. The model has a rotor with a diameter of 222 meters, blades with a length of 108 meters, and a swept area of 39,000 square meters.
According to Siemens Gamesa, the turbine prototype will be completed in 2021, and the model is going to be commercially accessible in 2024. According to the business, about thirty SG 14-222 DD offshore wind turbines may cover Bilbao’s yearly electricity usage. One SG 14-222 DD machine can supply enough energy to power nearly 18,000 ordinary European households each year, thanks to its 14 MW capacity.
The latest Siemens Gamesa B108 blades are used on the 222-meter diameter rotor. Using unique Siemens Gamesa blade technologies, each 108-meter IntegralBlade® is cast inside one piece. Furthermore, the turbine’s swept area of 39,000 m2 is nearly 5.5 conventional football fields. When compared to SG 11.0-200 DD offshore wind turbine, it permits the SG 14-222 DD to produce more than 25% more annual energy, according to Siemens Gamesa.
RWE placed the first definitive order for the SG 14-222 DD from Siemens Gamesa in March for a 1.4 GW Sofia wind farm off the coast of the United Kingdom. In addition, the new offshore giant has a nacelle weight of of 500 metric tons. In comparison to a heavier nacelle, Siemens Gamesa claims that the lighter nacelle allows them to safely use an improved tower and foundation substructure. According to the company, lower costs per turbine result from decreasing sourced materials and minimizing transportation expenses.
Siemens Gamesa has also agreed to provide the new turbine to 300 MW Hai Long 2 ventures in Taiwan and 2.6 GW Dominion Energy Coastal Virginia Offshore Wind (CVOW) commercial venture in the United States under preferred supplier agreements.
In 1976, Gamesa was founded as Grupo Auxiliar Metalrgico S.A. to develop new technology and apply them to new businesses. Robotics, microelectronics, aeronautics, and the creation of composite materials were among them. Joseba Mikel Grajales and Juan Luis Arregui created it.
Gamesa Eólica was founded in 1994 as a subsidiary dedicated to the production of wind turbines. In 1995, the company began developing, building, and operating wind farms, and the following year, it built its first wind farm. Vestas and Gamesa had a seven-year relationship that terminated in 2002.
On October 31, 2000, the company was formally listed on the stock exchange, and on April 24, 2001, it joined the elite IBEX 35 index. Gamesa bought Echesa, Cantarey, and Enertrón, three companies that make gearboxes, generators, and converters, in 2002.
