The European Offshore Wind Deployment Centre has generated power for the first time last weekend and is now exporting electricity to the Grid from the first of the11 turbines to go live.
The electricity was exported via the scheme’s 66 kilovolt (kV) subsea cabling – the first time that cabling of this capacity has been installed on a commercial offshore wind project in Scotland.
Power from the first two turbines from the Aberdeen Bay wind farm – the one that US president Donald Trump failed to prevent – is being exported through, two ‘strings’ of 4km export cable with a capacity of 66kV.
Compared with conventional cabling of 33kV less inter-array cabling is required leading to reduced construction cost. Overall, just over 14 miles of cabling has been installed from the wind farm to the onshore Blackdog substation – similar to the distance from Aberdeen to Stonehaven.
Adam Ezzamel, EOWDC project director, said: “First power from EOWDC reinforces North-east Scotland’s status as Europe’s energy capital and will help establish the region as an international centre for offshore wind generation.”
Jean Morrison, chairman of Aberdeen Renewable Energy Group, added: “The timescale between the first installation and first power is remarkable.
“The techniques and innovations developed at the EOWDC will be hugely significant for the industry and should help to reduce the future costs of offshore wind. As energy demand grows, we need to maximise the returns from our natural resources and offshore wind can help us do that.”
Scottish Energy Minister, Paul Wheelhouse, said: “Once the test and demonstration site is fully operational, not only will this help the offshore wind sector to further reduce its costs through lessons learned during operations, but the output from will itself add significantly to Scotland’s renewable electricity generating capacity, building on figures announced last month that showed installed capacity reached a record 10.4GW in the first three months of 2018 and which also provisionally indicated that renewable sources met an equivalent of 69% of Scotland’s electricity demand in 2017.”
