Council of State cancels licences and work approvals
Greece’s highest administrative court has struck down approvals for a 185 MW solar development that had been divided into scores of smaller projects. The Council of State cancelled 186 preliminary producer licences and 25 work approvals linked to the project near Pineios Lake. The ruling applies to the approvals granted for the development’s permitting pathway.
Common ownership and functional integration under scrutiny
The court said authorities failed to assess whether the installations, although presented as separate, effectively amounted to one investment under common ownership. It targeted a permitting approach that can allow large developments to be split into sub-1 MW units. Under that model, projects may be eligible for simplified permitting treatment.
Potential impact on clustered solar structures and battery pairings
The decision is not limited to the Pineios Lake site. Developers using clustered structures may face more comprehensive environmental and planning review if common ownership, location and technical design indicate the assets operate as a single development. The ruling could also affect projects paired with batteries where generation and storage have been organised through multiple special-purpose companies.
Permitting risk amid grid congestion and market pressure
The court action comes as Greece deals with grid congestion, renewable curtailment and weakening daytime power prices. In that context, permitting risk is added to an environment already constrained by grid limitations and price dynamics. For investors, the outcome highlights that regulatory structure may carry as much weight as project size when approvals are assessed.
