Proud of having the opportunity of working on this project!

Sustainable Graz is ready for a green future

In an era in which we increasingly experience the effects of climate change, sustainable initiatives are more important than ever. Helios is a good example of this. This Austrian project – unique in Europe – combines heat from solar energy and landfill gas with extensive storage capacity. A complex project which, among other things, required the construction of a major solar thermal energy installation with solar panels covering an area of 2,000 m2. The energy generated by the installation is transferred directly into the city heating network in Graz.

Step into the future

Austria has taken a major step forward on the road to ecological sustainability and future-proof heating with this large-scale sustainability project. The strength of Helios lies in the sheer size of the associated storage capacity. The project will be executed in different phases under the supervision of Arcon-Sunmark A/S, the contract principal.

Excavation works 

The pipes between the solar panels and the heat storage system run below the surface. Boels provided earthmoving equipment in the form of excavators and dump trucks for this work. A telehandler and electrical forklift trucks were required for loading and installing the solar modules. In addition, Boels supplied construction site fencing, scaffolds and work platforms for the installation work. The proximity of a Boels’ branch was an added bonus for the customer. Materials and equipment could be delivered quickly and support was always on hand.
