Nearly 21 TWh of Wind Energy Transmitted from German North Sea in 2024

In 2024, the transmission system operator (TSO) TenneT delivered approximately 20.8 TWh of wind energy from the German North Sea to the mainland, up from 19.24 TWh the previous year.

According to the company, the annual result in 2024 is around eight per cent higher than in the previous year. The amount of renewable energy transmitted to the mainland is enough to cover the annual demand of around six and a half million households, TenneT said.

At around 14 per cent, the share of North Sea electricity in 2024 was almost the same as in the previous year.

“The North Sea, with its enormous potential for wind energy, is a stable pillar in Germany’s energy mix and continues to gain in importance. However, in order to efficiently utilise its full potential, better use of the North Sea area is needed,” said Tim Meyerjürgens, CEO of TenneT Germany.

“The aim must be to achieve the actual energy yield, not the installed capacity, while keeping costs as low as possible. Intelligent re-zoning based on an energy target could save costs in the double-digit billions. Both for wind farm operators and for us grid operators. This would ease the burden on grid fees and strengthen Germany as a business location.”

On July 14, the offshore wind farms in the German North Sea reached a peak feed-in power of 6,291 MW, according to the TSO.

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

The installed capacity of wind turbines in the Baltic Sea was 1,828 MW (50Hertz grid area; previous year 1,352 MW). They supplied approximately 4.89 TWh, compared to 4.17 TWh in the previous year.

This brought Germany’s total offshore energy generation in 2024 to about 25.7 TWh, with the North Sea contributing 20.8 TWh.

According to the Federal Network Agency (BNetzA), Germany currently has 9.2 GW of offshore wind capacity in the North Sea and Baltic Sea.

The country’s renewable energy capacity grew by nearly 20 GW in 2024, reaching almost 190 GW, with solar and wind energy accounting for the majority of the increase, according to the initial data from BNetzA.
