Grid capacity map Portugal: official sources explained
Which official grid capacity maps exist for Portugal, how to read them, what they don't tell you, and a five-step workflow to screen a site before you talk to the grid operator.
Official sources
For Portugal: Capacidade de receção (REN) (REN); Capacidade da rede (E-REDES) (E-REDES).
How to read them
REN and E-REDES publish reception capacity per substation for new generation.
What they don't tell you
Capacity is often assigned by auction or agreement with the operator, and tables lag behind requests.
None of the official maps tell you whether there is usable land nearby, what the zoning is, or whether noise, flood or nature rules will block a project.
A five-step screen
1. Check the official source for the area's status. 2. On Gridscouter, find the nearest substations at the right voltage and their BESS, solar, wind or data-center score. 3. Run the land finder for plots within a set radius, filtered by size and land use. 4. Run quick due diligence on the best plots: noise, flood, nature, heritage and industrial-safety buffers. 5. Request a connection title (TRC) or check the next capacity allocation round.
Caveat
Gridscouter scores are estimates from open data, not grid operator capacity figures. Always confirm capacity with the operator.
