Economy

In the aftermath of the GROWIAN episode and simultaneously falling oil prices, wind energy exploitation in Germany had in fact already ceased when the Chernobyl nuclear reactor accident in 1986 once again prompted a move towards energy transition. The foundations for a prospering wind energy sector were laid by the 100 MW – later to be increased to 250 MW - support programme set in motion by the then Federal Ministry for Research, as well as the introduction of the German Electricity Feed Act of 1991.

 

Germany wind energy industry due to early market entry

Germany’s current status as an international leader in the wind energy industry is due to its early entry into wind energy development. Many countries around the world are increasingly converting to renewable energy-based energy systems, resulting in new areas of economic activity as well as opportunities for exports, value creation and employment.

Wind turbine operation (onshore or offshore) and service offer opportunities for value creation and employment on a regional level in particular. Industrial value creation, i.e. manufacturing of wind turbines and large components and design and development of network infrastructure is spread across many regions in Germany and in other countries. In the offshore sector, the companies and bodies within the maritime industry (ports) who make the infrastructure available also reap the benefits.

 

Regional economies – adding value

Greater use of wind energy and increased electricity production strengthen regional economies and secure local employment. Numerous studies prove the high amount of adding value by operating wind energy turbines.


Industry and Services

The wind industry, i.e. the industrial economy, is spread across all of Germany. Along with manufacturers of wind turbines, supplier industries also enjoy the benefits. Industrial wind energy research and the services sector also have an impact on all areas of Germany.

 

Offshore Wind Energy - Maritime Economy

As well as businesses that are already established within the wind energy sector, businesses in the maritime economy, in particular, also benefit from the expansion of the offshore wind energy industry. As they take on the diverse range of functions associated with the expansion of wind energy at sea, new business areas and sources of revenue develop for ports, which in turn is associated with additional employment benefits.

A wide range of stakeholders from various industry and service sectors has developed as a result of increasing national and international exploitation of wind energy. The value chain extends from planning and financing of turbines to production of wind turbines and large components, to transport and erection, to wind farm operation and maintenance. The offshore wind industry has developed as a specific arm of the wind industry.

 


1. Industrial Production and Manufacturing

Wind turbine manufacturers

Internationally operational companies are involved in manufacturing of wind turbines. Alongside companies that service both the onshore and offshore markets, wind turbine manufacturers also include a small number of producers focussing solely on the offshore market. In addition, some turbine manufacturers are part of industrial groups offering conventional energy production plans as well as onshore and offshore wind energy turbines.
Suppliers and component manufacturers


Suppliers and component manufacturers

The supplier industry is a central part of the offshore value chain. Suppliers include, in particular, companies from industry sectors such as steelwork and mechanical and electrical engineering. Important supplier companies within the wind energy sector include manufacturers of large components such as transmission units, foundation structures and towers as well as parts and components for powertrains, rotor blades and cables.

 


2. Project planning and development


Project planning and development companies

Planning and implementation of offshore wind farms are often managed by specialised companies. The project developer’s tasks include selection of a location, land use planning and categorization, analysis of wind climatic conditions at the planned location, selection of plant configurations and implementation of approval procedures. Project developers are also responsible for wind farm construction and for handover to the operator/investor. Project developers often involve other specialised service providers in on- and offshore projects who are responsible for the accompanying ecological investigations, for example.

 


3. Financing and Insurance

Banks and financial institutions

Due to the high investment costs associated with wind farms, projects are generally implemented by project consortia and are credit-financed by private or public banks. Groups of investors include large corporations, banking partnerships and municipal utilities, amongst others. Smaller companies and private investors may also participate in wind energy projects, by purchasing bonds for the purpose of capital generation, for example.

Insurance companies

Ambitious expansion targets for wind energy in various countries are leading to increased numbers of wind farms and to stronger demand for insurance services as a result. Risk management presents a major challenge on account of the large sums invested especially in offshore wind turbines. There are a range of risks associated with such projects, from ground investigation to transport, to making an wind farm operational.

 


4. Construction and maintenance


Transport and logistics companies

The transport and logistics sector has a central function because of the dimensions of wind turbines and large components. Special ships such as installation and transport vessels are required for the construction of offshore wind farms. Within the logistics sector, shipyards have an important role to play.


Construction companies

Turbine erection and cable laying are managed by specialised construction companies. They use specialist machinery e.g. to erect the foundations or specialist cranes required for the installation of rotor blades, for example. Several companies are often involved in projects as consortia.


Wind service and maintenance companies

Wind farm operators expect undisturbed wind farm operation. In this respect, service and maintenance of turbines plays an important role in operational management. Maintenance is managed by the turbine manufacturer or by external service providers. Foundation structures and rotor blades are relatively high-maintenance especially in offshore wind energy. Service and maintenance companies conduct special measures for inspection.

 


5. Testing and certification

There are a range of national and international requirements to be observed when constructing wind farms. Independent testing and certification bodies offer their services in order to ensure high quality in implementing a wind farm project.

 


6. Wind farm operation

The range of wind farm operators is very diverse and ranges from individual operators to cooperatives to engineering companies, individual municipal utilities, large electricity suppliers or municipal utility groups.
