Abstract
The adoption of energy storage technologies and renewable energy sources is essential for a sustainable, low-emission future under the European Green Deal and the Paris Agreement. However, diverse municipal resources, infrastructure, and socioeconomic conditions create challenges, including limited capacity, funding, and expertise. This paper builds on previous studies benchmarking Baltic Sea Region municipalities and identifying their storage potential. It presents a platform where six municipalities apply a modelling approach based on local parameters, generating scenarios to explore renewable energy and storage options. The results provide insights into addressing implementation challenges and demonstrate that while no single approach fits all, the platform supports municipalities, energy planners, and other stakeholders in simulating future perspectives, reducing emissions, and ensuring a stable, sustainable energy supply. meet EU targets while maintaining a stable and reliable energy supply.
