With more than 185 gigawatts of capacity installed across 88 countries, Vestas plays a central role in the global wind energy supply chain. The company employs over 33,000 people and leads in both onshore and offshore turbine technology.
Vestas has made significant investments in digital innovation, using real-time analytics and machine learning to optimise turbine performance and forecast maintenance needs. These technologies help maximise energy output while reducing operational downtime. Vestas’ commitment to sustainability is embedded in its manufacturing processes, with a growing emphasis on recyclable components and circular economy principles.
- ACCIONA: Integrated Renewable Infrastructure Solutions
ACCIONA, based in Spain, is a diversified infrastructure and renewable energy company with a strong presence across Europe. It operates wind farms in Portugal, Croatia and Hungary and has recently commissioned large photovoltaic facilities in Ukraine. What sets ACCIONA apart is its integrated approach, combining renewable energy generation with water treatment and sustainable transport infrastructure.
The company leverages its engineering expertise to deliver turnkey renewable projects, often in markets where infrastructure challenges are significant. By operating across multiple sectors, ACCIONA is uniquely positioned to offer holistic, low-carbon development solutions that contribute to Europe’s broader sustainability goals.
- Enel Green Power: Advancing Solar Manufacturing in Europe
Enel Green Power, a subsidiary of Italy’s Enel Group, is playing a pivotal role in reshoring solar manufacturing in Europe. Its 3Sun Gigafactory in Catania, Sicily, is on track to become the continent’s largest producer of bifacial photovoltaic modules. With an annual production capacity of 3 gigawatts, the factory is a cornerstone in strengthening the European solar supply chain.
The €600 million project, partially funded by the EU’s Innovation Fund, will not only reduce Europe’s dependence on imported solar panels but also generate thousands of high-quality jobs in southern Italy. Enel Green Power’s technological innovations are focused on high-efficiency, low-impact solar modules that can be deployed in a wide range of environmental conditions.
