ABB has won an order of more than $20 million from MHI Vestas Offshore Wind to supply energy-efficient and compact WindSTAR transformers designed for installation in wind turbines.

Borssele III and IV comprise the second phase of the Borssele wind farm. This phase constitutes a 731-MW wind project in the North Sea, 22 kilometers off the coast of The Netherlands and will be capable of providing enough clean energy to power more than 800,000 households.
ABB will supply its WindSTAR power transformer, which is specifically designed to fit into the tower of a wind turbine. This transformer enables a new generation of powerful offshore wind turbines to operate at the world’s highest voltage of 66 kV, which significantly reduces losses and increases efficiency. It also brings lifecycle benefits and cost optimization.
As turbine size increases for offshore (reaching 9.5 MW in this project, a world record power level for commercial offshore wind), transformers must remain compact and lightweight with a minimal footprint, while also meeting specific application needs, mechanical structural constraints and costs.
ABB pioneered transformer technology in the 1890s and has since been at the forefront of record-breaking innovations including the world’s highest voltage HVDC converter transformer and AC transformer at 1.1 and 1.2 million volts respectively.
