Offshore wind power yield from German North Sea up 8% in 2024

In total, 20.8TWh of offshore wind power was supplied from the German North Sea last year, up from 19.24TWh in 2023. Tennet said the 2024 offshore wind total is enough to cover the annual electricity needs of around 6.5 million households. 

Total wind feed-in for Germany came to around 150TWh in 2024, up from 139.56TWh in 2023. At around 14%, the share of North Sea electricity in 2024 was almost exactly the same as in the previous year.

“With its enormous potential for wind energy, the North Sea is a stable pillar in Germany’s energy mix, and it continues to gain in importance,” said Tim Meyerjürgens, CEO of Tennet Germany.

But focusing on the actual energy yield rather than installed capacity would help keep costs as low as possible, he added. “An intelligent redesign of the areas on the basis of an energy target could save costs in the double-digit billion range,” Meyerjürgens said.

For both wind farm operators and Tennet, as the grid operator, “this could relieve the burden on grid fees and strengthen Germany as a business location”, he said.

The maximum feed-in capacity of offshore wind farms in the German North Sea in 2024 reached 6,291MW on 14 July, Tennet said. Its offshore transmission capacity in the German North Sea is 8,032MW.

The installed capacity of offshore wind farms in the German North Sea was 7,387MW as of 31 December 2024, up from 7,106MW the previous year.
