First 'steel cutting'
for offshore substation
RWE Offshore Wind GmbH
Copenhagen, 12 December 2023
Milestone for RWE’s offshore wind farm Thor: End of November the construction of the Offshore High Voltage Station (OHVS) project officially commenced with a 'steel cutting' ceremony held at the HSM Offshore Energy yard in Schiedam, Netherlands. Both structures, the offshore substation and the corresponding jacket foundation, are built at this yard.
Thor wind farm will be located off the Danish west coast – approximately 22 kilometres from Thorsminde on the west coast of Jutland. To connect the wind farm to the Danish grid, RWE will build two new substations – one at sea and one on land. The substation at sea is the nerve centre of the wind farm: the electricity produced by the individual wind turbines is collected here and transformed to transmission-level voltage. The green electricity will be transported through export cables to the new-build onshore substation.
With a planned capacity of 1,000 MW, Thor will become Denmark's largest offshore wind farm to date. Once fully operational, no later than the end of 2027, the wind farm will be capable of generating enough green electricity to supply the equivalent of more than a million Danish households.
