Spatial optimisation and permitting Lessons learned from European Practice

Space is a limited resource and subject to conflicting interests. Given that all infrastructure impacts the environment in which it is built, development of renewable energy sources (RES) and electricity grid infrastructure requires robust and holistic spatial planning.

Approaches and methodologies combining spatial planning with energy system planning, can optimise electricity grid development and therefore, enhance RES integration.

But how can spatial optimisation help accelerate permitting for electricity grids? What is the role of acceleration areas for RES and grids, and how are they being implemented in Europe? What practices do grid operators deploy and what can be learned from them? These questions were at the centre of discussions in different fora throughout 2025. To explore these aspects, raise awareness, as well as disseminate good practices and related tools, RGI engaged with a wide range of stakeholders.

CINEA knowledge sharing workshop on permitting

On 7 May, RGI contributed to a workshop on permitting organised by CINEA, sharing insights and good practices on spatial optimisation and grid acceleration areas as tools to address permitting challenges. The event gathered over 200 participants, including Innovation Fund grantees, project developers, representatives from DG ENER, CLIMA, GROW, all EU Member States, and other stakeholders.

On 1 October, RGI contributed to a webinar organised by CAN Europe, in partnership with WWF EPO, BirdLife Europe and Central Asia, the European Environmental Bureau, and The Nature Conservancy. The event, entitled ‘From Policy to Action: Tracking Progress of Renewable Energy Spatial Planning and Designation of Acceleration Areas in Selected EU Member States’, launched a joint analysis by the Oeko-Institut, assessing the progress of ten EU Member States in transposing RED III, implementing spatial mapping and planning for renewables, and designating Renewable Acceleration Areas. RGI’s intervention brought in the perspective of electricity grids and spatial planning optimisation, particularly linking grid acceleration areas with the broader concept of renewable acceleration areas.
