Renewable energy is a key driver of the sustainable energy transition. To accelerate deployment, the Renewable Energy Directive was amended by Directive (EU) 2023/2413, commonly referred to as ‘RED III’, which raised the Union’s renewable energy target and introduced territorial instruments such as coordinated mapping and renewables acceleration areas. This article examines the legal mechanisms of RED III that have a territorial impact and assesses their interaction with spatial-planning, asking how implementation reshapes the relationship between EU-level regulatory influence and Member State discretion. Utilising doctrinal legal research and concepts from spatial-planning scholarship, the article analyses how RED III operationalises these area-based planning instruments and links them to project authorisation. Lithuania is used as an illustrative implementation example. The findings suggest that RED III does not establish an EU spatial-planning system but strengthens the territorially oriented governance of renewables by connecting plan-level choices to permitting. At the same time, it leaves Member States with substantial discretion over legal form and integration into national planning hierarchies. The article concludes that RED III is a turning point in a specific sense: it makes territorial steering a more explicit and legally structured component of EU renewables governance, without harmonising national spatial planning systems.
