The PREIS Group is sending a strong signal for sustainable growth and the future of energy infrastructure: at its Sevnica site in Slovenia, the company is investing up to 30 million euros in expanding its production capacity for transformer housings.
Strong investment in energy infrastructure
The global energy transition and the growing demand for electricity are driving increased demand for high-performance energy infrastructure. Transformers are a central component of modern power grids – and this is precisely where the PREIS Group comes in.
With the expansion of the PREIS Sevnica site in Slovenia, the PREIS Group is strengthening its position as a leading manufacturer of transformer housings in Europe and is responding specifically to rising demand in the energy sector.
Expansion of production capacity in Sevnica
The investment includes:
- the construction of new production halls
- the expansion of existing production areas
- the use of modern production and automation technologies
The aim is to nearly double production capacity while further increasing efficiency and quality.
These measures will enable PREIS to continue delivering complex energy infrastructure projects reliably and to the highest quality standards.
The PREIS Group as a key partner in the energy transition
The transformer housings produced by PREIS are essential for:
- the expansion of renewable energy
- the stability of power grids
- secure energy distribution worldwide
Through customised solutions and the highest manufacturing standards, PREIS positions itself as an important partner for international energy projects.
New jobs and regional value creation
The expansion of the site will create around 80 new jobs, particularly for skilled professionals.
This not only strengthens the competitiveness of PREIS but also makes an important contribution to the economic development of the Sevnica region.
Future-oriented strategy of the PREIS Group
The investment underlines the long-term strategy of the PREIS Group:
- focus on sustainable energy projects
- expansion of international markets
