110/30/20 kV Güssing substation construction – Elnos Group’s first project in Austria

Elnos Group has officially begun its first major energy infrastructure project in Austria – the construction of the 110/30/20 kV Güssing Substation. The project is being carried out in the federal state of Burgenland, known for its high solar-energy capacity, and plays a key role in integrating renewable sources into the region’s power system.

The town of Güssing, once an important military point, today is a rapidly developing hub in one of Austria’s fastest-growing solar regions. This new substation, together with the existing nearby facility, will double the capacity for accepting photovoltaic energy and significantly strengthen the security of electricity supply for the local community.

• Substation voltage level: 110/30/20 kV
  
• Investor: Netz Burgenland
  
• Main contractor: Cteam Energietechnik GmbH
  
• Total cable assembly length: Over 5 km of control and signal cables
  
• Number of transformer units: More than 7

The project is divided into two major phases:

Phase 1 (until May 2025)

• Assembly of primary equipment in the 110 kV switchyard
  
• Assembly of the 20 kV switchgear
  
• Assembly of protection and control cabinets
  

Phase 2

• Assembly of remaining primary equipment in the 110 kV switchyard
  
• Assembly of the 30 kV switchgear
  
• Laying and connection of all control and signal cables

• Coordination with the main contractor and investor under Austria’s strict technical and safety standards
  
• Integration with the existing grid to ensure compatibility with the Burgenland electricity network
  
• Specialised assembly and precise configuration of protection equipment according to high European standards
  
• Execution in a region that leads Austria in solar megawatt production, with increased operational and environmental requirements

Elnos Group has been engaged as a subcontractor, with responsibilities including:

• Electrical assembly works in both phases of substation construction
  
• Construction of parts of the 110 kV switchyard, including assembly of primary equipment (circuit breakers, disconnectors, current and voltage transformers)
  
• Assembly of 20 kV and 30 kV switchgear systems
  
• Assembly of protection and control equipment to ensure stable and safe substation operation
  
• Laying and connection of control and signal cables
  
• Connection of the substation to the local electricity system

• Increased capacity for receiving solar energy in Burgenland
  
• Improved stability of the electricity network in southern Austria
  
• Contribution to Austria’s strategy of achieving 87% renewable-energy production
  
• Strengthening Elnos Group’s market position and presence in Austria
  

The construction of the Güssing Substation represents a significant breakthrough for Elnos Group on the Austrian market, enabling further expansion in the EU’s energy infrastructure sector. This project further solidifies the company’s role in delivering complex power-engineering facilities across Europe.
