Siemens head of grid access Patrick Weber said that the company is launching innovative equipment that is installed on the turbine, doing away with the need for the entire AC substation.
"The new technology is connected to a wind turbine on a balcony or a more extended solution, a more rigid solution for different wind turbines," he said. "We call it offshore transformer module, or on a separate jacket. There are a lot of advantages in this new technology, reducing Capex and Opex."
Taking the example of the 402MW Dudgeon project in UK waters, Weber explained that the current single transformer platform could be replaced with two 200MW transformers attached to two turbines at the project.
However, Weber explained that HVDC solutions would still be on offer for customers seeking this technology.
