Siemens will supply the electrical equipment for two offshore substation platforms, which will be installed at the wind farm. The substations will bundle the power generated by London Array’s first 630 MW phase, which will use 175 Siemens SWT-3.6 wind turbines, before it is transported via high-voltage subsea cables – to be supplied by Nexans - to the coast. Each of the platforms will have two 180-MVA transformers and medium-voltage switchgear along with requisite protection, instrumentation and control equipment.
