A major renewable energy infrastructure project is to bring wind power from Shetland to the UK mainland via Europe’s first multi-terminal high-voltage direct-current (HVDC) interconnection, the firms behind the development announced yesterday. Hitachi ABB Power and Grids is to build an HVDC converter station on Shetland and an HVDC switching station in Caithness on the Scottish mainland, connected via subsea power cables. The link will transmit wind power generated by energy giant SSE on the islands to the UK mainland, where it will help meet electricity demand in the north of Scotland and beyond, the firms said. The announcement follows Ofgem’s approval last month of the £600m subsea cable link. Capable of transmitting 600MW, the Shetland HVDC Connection is expected to be operational in 2024. The switching stations will convert harnessed wind power from Alternating Current to Direct Current for the long distance transmission cables and then back again, leading to lower power losses and so reduced costs and a smaller carbon footprint.
