Accelerating the Energy Transition in Bulgaria, Hungary, and Romania through Renewable Acceleration Areas

Given Europe’s mounting climate ambitions and in the wake of the energy security crisis caused by Russia’s war on Ukraine, the European Union has adopted a new wave of legislative instruments, most notably the REPowerEU Plan and the revised Renewable Energy Directive (RED III). These frameworks task Member States with facilitating a swift deployment of renewable energy through spatial planning and the creation of Renewable Energy Acceleration Areas (RAAs).

This policy position provides a strategic analysis of progress, barriers, and recommendations for Bulgaria, Hungary, and Romania. It explains the challenges and makes recommendations for faster development of renewable energy in these countries.

The RENewLand project, launched in 2023, supports this assessment. By providing a science-based and stakeholder-driven methodology for spatial planning of renewables, RENewLand aims to bring support to these countries in fulfilling RED III requirements. However, despite technical tools and regional cooperation, implementation remains hindered by institutional fragmentation, data gaps, regulatory delays, and limited local engagement. This paper offers a comparative diagnosis and targeted policy guidance to address these shortcomings and accelerate progress toward the 2030 climate and energy goals.
