Slovenia has inaugurated its first solar power plant installed on a noise barrier along a highway, marking a national first and a new use case for renewable energy deployment. The project forms part of DARS’s broader strategy to support sustainable development, reduce carbon emissions, and improve energy efficiency.
The solar plant was commissioned at the Šmarje Sap West rest area, approximately 10 kilometers from the capital Ljubljana, along the motorway connecting Slovenia and Zagreb. The project reflects a practical approach to leveraging existing infrastructure for clean energy generation, without requiring additional land allocation.
DARS initially announced plans to develop similar projects in July 2023 as a pioneering concept. This installation represents the first tangible implementation of that strategy and serves as a starting point for a broader pipeline aimed at integrating renewable energy solutions into non-traditional sectors such as highway infrastructure.
From an industry perspective, the project highlights a strategic shift in solar deployment models. By utilizing existing assets (including noise barriers and public infrastructure), it enables capacity expansion without placing pressure on agricultural land or urban areas. This approach also strengthens the case for replicability across other markets, particularly in Central Europe and the Balkans, where land-use constraints and regulatory considerations present similar challenges.
Commenting on the project, Andrej Ribič, Chairman of the Management Board of DARS, emphasized that the initiative extends beyond electricity generation - “The project is not only important for electricity production, but also as an example of thoughtful siting of renewable energy facilities without impacting traffic safety or routine highway maintenance”.
The electricity produced will be used for DARS’s own consumption, including road lighting and tunnel systems, enhancing energy independence and optimizing energy management.
Looking ahead, DARS plans to continue expanding its solar portfolio as part of its long-term strategy, with the objective of cutting carbon dioxide emissions by 30% by 2030 compared to 2024 levels. These efforts underscore the growing role of decentralized energy solutions in supporting the decarbonization of transport infrastructure and the broader energy transition.
