Making the energy transition happen

By expanding renewable energy technologies and future-proofing our grids

Why do we need the energy transition?

Almost 60% of the energy consumed in Europe is imported from outside the EU. This leaves Europe dependent not only on other countries, but also on nuclear power and fossil energy sources such as coal. And even when renewable energy is generated within the EU, the capacity needed to store green electricity is lacking. At the same time, the infrastructure needed to distribute that electricity is not being modernised quickly enough. In Germany, for example, outdated grids mean that green electricity does not always reach the places where it is needed. Industry, too, faces challenges with processes that consume large amounts of energy but are difficult to electrify.

We are building the infrastructure for a secure energy future

Europe needs to get ready for the energy transition. That means generating more renewable energy and creating the storage capacity needed to make it available even when the wind is not blowing and the sun is not shining. Reliable infrastructure is essential to securing energy supplies, reducing costs and strengthening Europe’s energy independence.

Where STRABAG is already making a difference

By building new power transmission lines, we are helping to transport wind power from northern Germany to the south of the country. We also have extensive expertise in plant engineering and construction, including the delivery, together with Siemens Energy, of a major electrolyser plant for OMV in Austria.

Solar energy on the rise

Electricity generated from solar energy has tripled in just five years.
Grid expansion for the energy transition

We are building almost 400 kilometres of power transmission lines as part of the SuedLink and SuedOstLink projects in Germany – nearly one-third of their combined length.
Renewables over coal

In 2025, renewable energy overtook coal in global electricity generation for the first time in 100 years.

How do we make the energy transition happen?

A range of measures is needed to fully harness the potential of renewable energy, including expansion, modernisation and storage. Find out more about our projects.

Power lines

Two major power transmission routes, SuedLink and SuedOstLink, are being built across Germany as part of the country’s energy transition – and STRABAG is playing a major role in their construction.

Wurten storage facility

New is not always necessary: by expanding the existing infrastructure and raising a dam, we are doubling the storage capacity of this Austrian water reservoir.

Electrolysis plant

Green hydrogen is highly versatile and can be produced sustainably. In Austria, STRABAG and Siemens Energy are building one of Europe’s largest electrolyser plants for OMV.

More about sustainable hydrogen

The energy transition represents a major opportunity for Europe. By expanding our grid and storage capacities, we are helping to secure our energy supply for the long term. To achieve this, we need to modernise existing grids and establish renewable technologies such as wind and solar power. Renewable energy makes our infrastructure more reliable and flexible while helping to reduce costs.

Frequently asked questions about the energy transition:

Why do we need to expand renewable energy?

The energy transition is an important means of helping the EU achieve its climate targets. Energy from renewable sources produces significantly fewer CO2 emissions than fossil fuels. Resources such as wind and sunlight are also available in virtually unlimited quantities. Expanding renewable energy and the infrastructure it requires offers many advantages. The most important are that Europe becomes less dependent on fossil fuel imports while conserving natural resources.
What does modern energy infrastructure look like?

A robust infrastructure is essential if renewable energy is to be used on a broad scale. Only then can electricity reach the places where it is needed. Generation, storage and distribution need to work together efficiently, including for new technologies. Hydrogen, for example, is expected to play a much greater role in the future. This will require not only additional production facilities, but also the corresponding infrastructure.
Why is energy storage important?

Storing sustainable energy is at least as important as generating it. Energy supplies also need to be secure on cloudy days and when there is little wind. Electricity storage will therefore play an important role in both the energy transition and grid stability. It makes energy available when it is needed while helping to keep supplies secure and affordable.
