Siemens supplied two Offshore Transformer Modules (OTMs) for the Beatrice offshore wind farm grid connection, which later formed part of the Beatrice OFTO transmission asset set. These Siemens OTMs function as compact offshore HVAC substations that step up the wind farm’s 33kV array voltage for transmission to shore. The modules were installed on jacket foundations within the Beatrice wind farm area and are integral to exporting the 588MW of offshore wind capacity into the Scottish transmission network.
