The first commercial windfarm with 66kV cables

JDR has been awarded the contract by Boskalis Cables to supply inter-array cables for Scottish Power Renewables’ East Anglia One (EA1) offshore wind farm.

EA1 is the world’s first commercial application of 66kV cable technology. JDR will design and manufacture 155km of array cables including end terminations. The innovative 66kV high voltage technology enables increased power transmission back to shore from large, high powered offshore turbines compared to 33kV cables. JDR will also provide a unique cable management system at each offshore wind turbine generator which allows for a 66kV topside connection to the switchgear cables.

With an overall capacity of up to 714MW, EA1 is the first of four projects in the East Anglia Zone. The offshore wind farm will consist of up to 102 wind turbines and will be located 43km off the Suffolk Coast in the southern North Sea. The wind farm is expected to power 500,000 homes when fully operational in 2020.

JDR will manufacture the cables at its state-of-the-art facility in Hartlepool, UK, with delivery scheduled for Q1 2019.
