Wind power problems and challenges: Wind farms in the North and Baltic Seas remain drivers of the energy transition

New wind farm projects are being developed in the middle of the North and Baltic Seas, which represent a decisive step towards achieving Germany's climate goals. Wind farms play a crucial role in energy supply, especially on days when wind conditions are ideal.

Renewable energies: status quo and objectives

The Renewable Energy Act (EEG) stipulates that at least 80 percent of gross electricity consumption should come from renewable energy sources by 2030. It is noteworthy that over 53 percent of the energy generated in 2023 came from renewable sources, with wind energy having a dominant share of almost 29 percent.

Wind farm expansion as a solution to energy transition challenges

The expansion of offshore wind farms is crucial to increasing the pace of the energy transition. It is planned to increase the capacity of wind farms to at least 30 gigawatts by 2030, to at least 40 gigawatts by 2035 and to at least 70 gigawatts by 2045.

However, despite all efforts, there are still challenges that need to be overcome, such as limited space at sea and the need to accelerate the expansion of network infrastructure. In addition, logistical challenges such as shipping wind turbines and foundations and the long delivery times for converters represent further hurdles.

Wind farms and their development in recent years

It is remarkable that there are already more than 30,000 wind turbines in Germany, around 1,500 of which are in the North and Baltic Seas. These wind turbines generated almost 70 terawatt hours of electricity in the first half of 2023. Offshore wind farms are particularly efficient because they benefit from higher energy yields due to more consistent wind conditions.

The need for a more efficient power grid

Despite the increasing energy production from wind farms, expanding the power grid is essential to avoid bottlenecks and distribute the energy generated efficiently. There is an urgent need to expand and modernize the power grid to accommodate the growing amount of energy.

Challenge

Germany faces the challenge of quickly modernizing and expanding its energy infrastructure. Wind farms play a crucial role in this. By increasing investment, technological innovation and accelerating grid expansion, Germany can achieve its energy transition goals and ensure a sustainable future for future generations.

Wind energy has been a key technology for years, making a significant contribution to the energy transition in many countries. Building wind farms at sea, particularly in the North and Baltic Seas, is a crucial step to reduce emissions and reduce dependence on fossil fuels.

1. Objectives of the Offshore Wind Energy Act

The core of the Offshore Wind Energy Act is the accelerated expansion of offshore wind farms. The goals set are ambitious: 30 GW by 2030, 40 GW by 2035 and an impressive 70 GW by 2045. For comparison: at the end of June 2023, the capacity was just 8.4 GW.

2. Current status and challenges

The majority of the installed capacity (7.1 GW) is in the North Sea, while the Baltic Sea, especially Mecklenburg-Western Pomerania, only accounts for a fraction at 1.3 GW. However, given the current pace of expansion, it appears unlikely that the set goals will be achieved.

3. Possible measures

Additional incentives and investments are needed to accelerate expansion. This could include improved network infrastructure, government subsidies and cooperation with private investors.

4. Significance for the energy transition

Offshore wind farms are not only environmentally friendly, but also extremely efficient. Because the wind is more consistent and stronger at sea, offshore turbines can often produce more electricity compared to their onshore counterparts.

📝 Expert opinions and details

🌬️ Wind power on the high seas

Offshore wind farms use the constant and strong wind on the open sea. They are therefore often more powerful than onshore wind farms. The expansion of this technology can make a significant contribution to reducing CO2.

🚢 Infrastructure requirements

The construction and operation of offshore wind farms requires specialized vessels and technologies. In addition, the systems are more maintenance-intensive and more expensive, which in turn requires higher investments.

🌏 Global perspectives

While Germany is a leader in the field of wind energy, other countries are also pursuing the expansion of offshore wind farms. This global trend could bring additional investments and technology transfer to Germany.

🤝 Cooperation is key

In order to achieve the goals set, government agencies, private investors and environmental organizations must work closely together. Together they can overcome hurdles and accelerate expansion.

🔋 Integration into the power grid

Another important aspect is the integration of the energy generated into the existing power grid. This requires investments in modern technologies and network infrastructure.

Germany has a limited sea area that is used by various interest groups. The installation of wind turbines at sea is a complex task due to various challenges.

1. Limited space for wind turbines 🌊

• Germany only has a limited maritime area. Therefore, there is not much space to set up wind turbines.
• The sea areas are used by other groups such as the military, fishing, shipping and sand and gravel mining. This means that the areas for wind turbines are limited.

2. Problems with the placement of the systems 🌬️

• Wind turbines must be installed at a certain distance from each other. If they are placed too closely, shading effects can occur. This means that one system can “take the wind away” from the other, reducing its efficiency.

3. Allocation of areas by the Federal Network Agency 🏢

• The Federal Network Agency is responsible for allocating areas for wind turbines. But that alone is not enough.
• There are many logistical challenges that must be overcome before a system can even be installed.

4. Transportation and installation problems ⛴️

• Wind turbines and their foundations are large and heavy. They have to be shipped and then installed in the sea.
• Special heavy-duty areas in the ports and quay walls are required to transport these heavy components. But such facilities are currently not available in many ports.
• There is also a need for further infrastructure to support the rapid development and installation of wind turbines.

5. Do we need more heavy port infrastructure? 🏗️

• There is currently a lack of port areas and quay walls capable of carrying heavy loads. So there is a clear need for infrastructure development in this area.
• However, it looks like building such facilities will take time. This could slow down the development of offshore wind energy in Germany.

Wind energy in Germany: A stormy road ahead 🌬️

The development of wind energy in Germany is impressive. In recent years, Germany has developed into one of the leading countries in wind energy production. But with the rapid increase in installed capacity, challenges have also arisen.

1. Rapid increase in wind energy 📈

The increasing number of wind turbines shows the clear trend towards green energy. Using wind as an energy source is not only clean but also renewable. This means we are not at risk of “using them up” as is the case with fossil fuels.

2nd challenge of power grid expansion ⚡

A big problem is that the green electricity generated is not always consumed where it is generated. The north of Germany, where there is a lot of wind, produces a lot of this renewable energy. But the main consumption is in the industrial south. This requires a well-developed network that can transport electricity from north to south. But here we encounter difficulties.

3. Delays and obstacles 🚧

Local and political resistance has slowed the expansion of the power grid. This means that a large part of the energy produced is not used because it cannot be transported to where it is needed. Currently, only 2,500 kilometers of the planned 14,000 kilometers of lines have been completed. These delays not only cost money, but also prevent Germany from realizing its full green potential.

4. The need for accelerated network expansion 🔄

There is an urgent need to accelerate the expansion of the electricity grid. This would not only help to efficiently use the green surplus, but also reduce energy costs for consumers and reduce environmental impact.

5. Optimistic outlook 🌟

Despite the current challenges, Germany remains a leader in wind energy production. With proper planning and implementation, the country can achieve its ambitious goals and continue to play a pioneering role in renewable energy.
