Significant Increase in Offshore Wind Energy Production in the North Sea

Sun 26th Jan, 2025

The offshore wind energy capacity in the North Sea has recorded a notable increase, with production rising by approximately eight percent compared to the previous year. In 2024, the total output reached 20.8 terawatt-hours (TWh), sufficient to meet the annual energy needs of around 6.5 million households, as reported by the network operator Tennet.

This growth is part of a broader trend in Germany's renewable energy sector, which saw a total wind energy generation of roughly 150 TWh in 2024, with the North Sea contributing about 14 percent of this total. The wind farms located in the Baltic Sea, managed by the company 50 Hertz, generated 4.89 TWh, marking an increase of 0.72 TWh from the previous year.

In terms of capacity, the wind parks in the North Sea expanded by 281 megawatts, bringing the total to 7,387 megawatts. The peak output was recorded on July 14, reaching an impressive 6,291 megawatts. The installed capacity of wind turbines in the Baltic Sea also saw growth, increasing by 476 megawatts to a total of 1,828 megawatts.

To further enhance the efficiency of offshore wind energy production, Tennet's Germany CEO, Tim Meyerjürgens, has advocated for improved land use strategies. He emphasized that focusing on actual energy yield rather than just installed capacity is essential for minimizing costs. Meyerjürgens suggested that optimizing the allocation of offshore areas based on energy production goals could result in savings amounting to tens of billions of euros, thereby alleviating network fees and bolstering Germany's economic position.

However, this viewpoint has drawn sharp criticism from environmental organizations such as Nabu. Kim Detloff, the head of marine protection at Nabu, expressed concerns that the proposed changes could lead to detrimental effects on marine ecosystems. Detloff argued that increased density in wind farm development could exacerbate issues related to wind shadow effects and loss of productivity due to overcrowding, potentially compromising established planning and environmental standards.

The environmental impacts of wind energy expansion are a contentious issue, with Detloff warning that ecological damage is escalating. He called for a reevaluation of the current approach to offshore wind development, advocating for reduced pressure on marine environments rather than increased exploitation.

As Germany continues to pursue its energy transition goals, the balance between expanding renewable energy capacity and protecting marine ecosystems remains a critical discussion point among stakeholders in the energy sector.
