Vattenfall applies to extend life of cutting-edge offshore windfarm

Vattenfall applies to extend life of cutting-edge offshore windfarm
Vattenfall wants to extend the lifetime of the EOWDC to match the lifetime of components used in it

The developer of a first-of-its-kind test site for offshore wind energy is seeking to extend its lifetime beyond the 22 years originally anticipated.

Vattenfall, the Swedish energy group which operates the pioneering European Offshore Wind Deployment Centre (EOWDC) in Aberdeen Bay, is applying to the Scottish Government to extend its operational lease from 22 years to 25 years.

Vattenfall project director Kevin Metcalfe said, “We have submitted to Marine Scotland an application to prolong the lease of the EOWDC from 22 years to 25 years. If approved by Marine Scotland and Crown Estate Scotland, the longer operating life of the windfarm will deliver a boost to local jobs, businesses and the generation of more fossil-free electricity.”

The application aims to bring the operational lease in line with the design-life of windfarm components and safely operate the offshore wind test and demonstration site for an additional three years. This period excludes the time needed to decommission the windfarm.

The EOWDC’s 11 turbines, currently the world’s most powerful, have a total generating capacity of over 93.2 MW, which can supply the equivalent of 70% of Aberdeen’s household electricity demand. The project will annually prevent more than 130,000 tonnes of CO2 from entering the atmosphere.

The circa £300M (US$393M) EOWDC is a test bed for innovation in the offshore wind sector. It generated first power in July 2018. An indepth description of the construction of the project can be found here.
