10 Wind Energy Companies in Bremen – this is where the Wind comes from

Bremen and Bremerhaven are home to around 80 companies in the wind energy sector. With a total of 3,000 employees, these businesses cover the entire value chain and make a significant contribution to the local economy. Since 1990, wind turbines have been planned, built and serviced in Germany´s smallest federal state.

These are impressive figures that prove: despite limited space for large-scale wind farms, the region has become a strategic hub for onshore and offshore wind energy. Over the years, Bremen has developed deep expertise across the full wind energy value chain.

In this article, we present 10 leading wind energy companies in Bremen and Bremerhaven that combine long-standing experience with innovative solutions. Whether you’re developing a new wind farm or seeking service partners, you’ll find what you need right here.

As a project developer, wpd manages every stage oft he project lifecycle: from site analysis and financial assessment to purchasing, sales, and long-term operations. More than 1,300 employees work across the group.

2. Energiekontor AG

A true pioneer, Energiekontor has been active in the wind energy sector since 1990, back when turbines were still measured in kilowatts rather than megawatts. Since then, the company has developed over 170 wind farms with a combined capacity of around 1.5 gigawatts, including projects in other european countries like the UK and Portugal. In addition to new installations, its portfolio also includes repowering projects and solar park development. Energiekontor manages 444 MW in owned assets.

3. Nordwest Assekuranzmakler GmbH & Co. KG

NW Assekuranz provides insurance for both onshore and offshore wind farms. But it’s about far more than just policies: the company offers technical risk assessments, damage analysis and claims management, and provides support throughout the entire lifecycle of a wind energy project.

4. Ocean Breeze Energy GmbH & Co. KG

Ocean Breeze Energy owns and operates the BARD Offshore 1 (BO1) wind farm, Germany’s first commercially operated offshore wind farm, located roughly 100 km off the German North Sea coast. Since its commissioning in 2013, it remains one of the country’s largest. Its 80+ turbines deliver a combined nominal capacity of 400 megawatts. The company ensures efficient and safe operations at sea.

5. Deutsche WindGuard Engineering GmbH

Just like aircraft, rotor blades need wind tunnel testing to optimize aerodynamic performance. Deutsche WindGuard operates a wind tunnel center in Bremerhaven, offering aerodynamic testing for rotor blades. The center includes large-scale, climate, and pressure wind tunnels for simulating diverse environmental conditions.

6. Rhenus Offshore Logistics

Logistics in the offshore wind energy sector is particularly demanding: due to the unpredictable weather at the North Sea, crews can only reach offshore platforms on about 50% of the days in a year. On the remaining days, companies like Rhenus spring into action. They deliver materials, skilled workers, and supplies offshore converter stations and wind turbines via ship, while also handling port operations, ship provisioning, and logistical planning.

7. SPIE Wind Germany GmbH

From construction to installation, maintenance, and servicing – SPIE Wind Germany ensures wind turbines are erected and stay operational. This requires skill and adaptability, as each site comes with unique environmental and regulatory challenges. Beyond turbine installation, the company also designs power routes, plans grid connections, and manages permitting processes. SPIE Wind Germany is part of the French SPIE Group and employs around 3,000 people in Europe.

8. RTS Wind Group

Since 1997, RTS Wind Group has been offering service solutions in the wind energy sector, operating in more than 40 countries with over 500 employees. Its core services include installation, maintenance, repair, upgrades, and personnel services for wind energy projects.

9. Deutsche Windtechnik

With more than 2,500 employees, Deutsche Windtechnik ensures the reliable operation of around 7,500 wind turbines. Its full-service portfolio includes maintenance, remote turbine monitoring, inspections, and technical assessments. The company runs its own training center and actively participates in research projects to advance new technologies in turbine maintenance and operation.

10. Lanthan GmbH & Co. KG

The wind energy industry in Bremen isn’t only shaped by major corporations. Smaller players also play a key role – like Lanthan, a specialist in aircraft warning lighting systems. These red lights, mounted on wind turbines, industrial chimneys or tall buildings, are subject to strict approval processes. According to the company, it is one of the leading manufacturers in this field and currently employs around 20 people in Bremen.
