Renewable energy communities in Sweden: a techno-economic analysis of single-owner, multiple-consumer building-level energy sharing

Renewable Energy Communities (RECs) are evolving as key enablers of climate action and renewable energy integration. However, they face technical and economic challenges, particularly in energy allocation, pricing structures and stakeholder expertise. Existing studies primarily focus on multi-owner RECs, overlooking single-owner models – increasingly relevant in urban settings. This study analyzes a real-world single-owner REC, comparing hourly- and monthly-based pricing models and four energy allocation strategies using techno-economic metrics.

Results show that hourly-based pricing reduces costs but lowers revenues. Furthermore, allocation strategies minimally impact technical performance in such REC setting. While the differences between the strategies themselves are negligible from the landlord’s perspective, the impacts on tenants in terms of cost distribution and fairness could vary, requiring further investigation.
