Vattenfall delivers first power from Vesterhav wind farm

Denmark: Vattenfall has delivered first power from its 170 MW Vesterhav Syd wind farm sited off the coast of Denmark close to its 180 MW Vesterhav Nord scheme.

“It is a huge relief to finally deliver electricity from Vesterhav Syd. When you look at the challenges there have been throughout the process, since we won the tender in 2016 and during the construction work, we are extra proud today,” said project director for Vesterhav Syd and Nord at Vattenfall, Mathilde Damsgaard.

The project’s 20 turbines were erected from July to September, and the plan was to connect them to the electricity grid immediately after installation. That had to be changed after problems with the installation of cables linking the site to the power grid on land. Vattenfall’s contractor couldn’t bury the wires deep enough in the seabed, but after switching the method and tool, the process is bearing fruit. Tough weather conditions also slowed progress.

There are also warning lights on the turbines, only to activated if a plane approaches one of the Syd or Nord sites. The radar-controlled lights can only be activated after the parks are fully operational. Until then, they will be on all the time – white during the day and red at night.

Ten of the turbines are producing power, with the final 10 expected to be connected within weeks. Vattenfall is also working hard to establish connection to the wind turbines in Vesterhav Nord. Both parks must be connected by the end of the year. When fully operational, they will supply electricity corresponding to the consumption of approximately 350,000 households.

The later connection of wind turbines means that the production of electricity in 2023 will be lower than expected. However, Vattenfall doesn’t expect a loss for the park’s owners over the lifetime, as production and income are simply pushed forward in time.
