Ørsted has revised commissioning schedules for the 2,852 MW Hornsea 3 offshore wind project in the UK and the 913 MW Borkum Riffgrund 3 project in Germany due to grid operator delays and grid outages.

Chief executive Rasmus Errboe said the hold-ups were linked to grid operators in the UK and Germany.

For Hornsea 3, National Grid informed Ørsted that the onshore connection would be delayed by two months. The company has moved the expected commercial operation date from the second half of 2027 to the fourth quarter of 2027 or the first quarter of 2028.

Errboe said Ørsted is taking a cautious approach to the new schedule, but does not expect a meaningful financial impact on the project.

At Borkum Riffgrund 3, turbine commissioning is progressing more slowly than expected, mainly due to curtailment and unplanned outages on the German grid.

Full commissioning has been pushed back by at least four months, from May 2026 to August–September 2026.

Errboe said the revised schedule is not expected to have a meaningful effect on Ørsted’s figures or EBITDA, citing current power prices in Germany.

The German project has commissioned 64 of its 83 turbines.

Errboe said the delays show the need for grid upgrades across Europe as more renewable energy capacity is added.
