Major milestones have been reached at two of SSE Group’s most symbolic net zero UK infrastructure projects. The first came as the official start of offshore construction work got underway at what will be the world’s largest offshore wind farm, the GBP 3.6 billion Dogger Bank. It saw work to install the HVDC export cable, which will connect the first phase of the windfarm, more than 130km off the coast to a landfall point at Ulrome, in East Riding of Yorkshire.Elsewhere the historic project to connect the Shetland Islands to the GB electricity grid stepped up with the arrival of four new 168 tonnes transformer units.The units are key components in the operation of Kergord substation and will play a vital role in the GBO 600 million Shetland HVDC link. Once complete, the link will transport clean, green energy from the islands and help Shetland’s future security of supply. The units, which will be transported from Lerwick harbour by a specialist haulier, will be moved overnight, under the guidance and supervision of Police Scotland, to avoid disruption to the local community.
