Energy Communities in Spain 2026: data, map and examples
Spain had 659 energy communities at the end of 2024, 44% more than the previous year. These are entities where neighbours, SMEs and local authorities produce and share renewable energy collectively, reducing electricity bills by 20% to 60%.
What is a Renewable Energy Community (REC) and how is it different from a CHP?
A REC (Renewable Energy Community) is a legal entity formed by citizens, SMEs and local authorities who join together to produce and consume 100% renewable energy collectively and locally. Its main goal is not profit, but energy savings and environmental benefit for the community.
Physical vs. virtual batteries in industry: which one is best and when
The physical battery stores kWh in a computer and allows you to move energy to evening/night and cut power peaks (backup included). The virtual battery saves €: monetize your surplus on the bill without installing anything. The choice depends on your load curve, peaks and budget; in many cases, the hybrid strategy (physical + virtual) maximizes savings.
