Greece’s Largest Highway Solar Network Goes Live on Olympia Odos

Greece’s Largest Highway Solar Network Goes Live on Olympia Odos

(IN BRIEF) Olympia Odos has inaugurated Greece’s largest solar installation along a motorway, deploying 10 MWp of photovoltaic panels across 19 sites in Achaia, Corinth and Western Attica. Financed and constructed in under two years via the concession model, the €10 million project harnesses roadside land, toll-station canopies and rooftop space to fully power the highway’s lighting, signage and ventilation systems. This milestone is part of Olympia Odos’s broader strategy to cut scopes 1 and 2 emissions by 2030, complemented by LED lighting upgrades and expansion of EV fast-charging to 26 chargers per 100 km. The initiative underscores the effectiveness of private-public partnerships in accelerating green infrastructure and sets a new benchmark for sustainable transport networks in Europe.

(PRESS RELEASE) PARIS, 2-Jul-2025 — /EuropaWire/ — Greece’s most extensive highway solar initiative is now energizing Olympia Odos. Deploying 10 MWp of photovoltaic capacity across roadside plots, toll-canopy arrays, and facility rooftops, the system meets all of Olympia Odos’s electricity requirements. This rapid rollout was made possible through the concession framework.

In a ceremony attended by Infrastructure and Transport Minister Christos Dimas, Olympia Odos—operator of the Athens–Patras–Pyrgos motorway and a VINCI Highways subsidiary alongside Avax, Aktor and TERNA—unveiled its expansive solar network and officially opened the Kiato solar park. Comprising 19 installations in Achaia, Corinth and Western Attica, the network utilizes under-used roadside land, toll station roofs, and operational center buildings. Once final grid connections and technical tweaks are complete, the entire 10 MWp portfolio will be live by year-end.

Delivered in under two years under the state concession, this €10 million investment exemplifies how private capital can accelerate green infrastructure development. It also forms a core pillar of Olympia Odos’s strategy to shrink its carbon footprint. Alongside adopting LED lighting throughout the route, the operator plans to reduce its scopes 1 and 2 emissions by 2030. Efforts to curb users’ scope 3 emissions include rolling out a new generation of electric-vehicle fast chargers—raising coverage to 26 chargers every 100 km by December, aligning with Europe’s leading networks.

Minister Christos Dimas remarked, “This is Greece’s largest motorway solar network—an investment exceeding €10 million, completed in under two years, and a model for sustainable, self-sufficient infrastructure. Kiato and its neighboring communities are among the biggest beneficiaries.”

Belen Marcos, President of VINCI Highways, added, “Decarbonizing road transport demands robust investment and swift delivery. The concession model does both, enabling private finance under public guidance. In collaboration with GEK TERNA, AKTOR and AVAX, we’re proud to take this significant step toward making Olympia Odos greener.”

Dr. Panagiotis Papanikolas, CEO of Olympia Odos, emphasized, “We’re not merely building roads—we’re shaping a sustainable future. Installing 19 solar parks with a combined 10 MWp means our operations are entirely powered by renewables, a vital milestone on our path to net zero by 2030.”

This landmark project positions Olympia Odos—and Greece—among European leaders in environmentally responsible transport infrastructure, illustrating how innovation and sustainability can drive major mobility projects.
