Grid capacity map Switzerland: official sources explained
Which official grid capacity maps exist for Switzerland, 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 Switzerland: Swissgrid (Swissgrid).
How to read them
Swissgrid runs the transmission grid; most connections go through one of the roughly 600 local utilities.
What they don't tell you
No national capacity map is published, so substation proximity and voltage are the best public screen.
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. Ask the local utility (EVU) about connection conditions early.
Caveat
Gridscouter scores are estimates from open data, not grid operator capacity figures. Always confirm capacity with the operator.
