🏘️ Can I share solar power with neighbours or join an energy community in Portugal?

The short answer

Energy sharing lets households use power produced by a shared installation, a neighbour or a community project. Whether and how it works depends on the national rules.

📜 The rules in Portugal

Energy sharing and communities

Portugal has collective self-consumption (autoconsumo coletivo, ACC) and renewable energy communities (comunidades de energia renovável, CER) under Decreto-Lei 15/2022. A managing entity (EGAC) registers the project with DGEG through the Portal do Autoconsumo; the grid operator checks each member can join.

  • Collective self-consumption needs at least two participants: households, businesses, condominiums or public services. They must appoint a participant or independent entity as EGAC and use a certified installer. (erse.pt)
  • Joining keeps your rights as a consumer: your supply contract and your free choice of supplier do not change. (erse.pt)
  • Decreto-Lei 130/2026 (transposing Directive (EU) 2024/1711) added a definition of energy sharing (partilha de energia) to Decreto-Lei 15/2022, covering the self-consumption of shared renewable energy. (pgdlisboa.pt)

❓ Questions

Do I have to own solar panels?

No. In many schemes you can take part as a member or user without owning an installation.

Does my supplier stay the same?

Usually yes. The shared power is counted first and your supplier provides the rest.

Who registers the sharing?

Normally the grid operator or the body named on this page. Ask them before you start.
