The map is the fastest way to see where the Dutch grid has room. Every area is colored by its A–F grade, from A (open) to F (fully congested).

​
Grades at every level

The same grades are available at five levels of detail:
  • Province — the broadest view, useful for portfolio-level scanning
  • Municipality — compare neighboring towns
  • Postcode (PC4) — the level most connection requests are screened at
  • TenneT feeding area — the high-voltage station that ultimately feeds an area
  • DSO — per network operator
Each level has its own page with the grade history and underlying numbers, so you can link directly to an area.

​
Consumption and feed-in

Every area carries two independent grades:
  • Consumption — how quickly a new data centre, factory, heat-pump cluster, or EV hub can be connected
  • Feed-in — how quickly a new solar farm, wind project, or battery in feed-in mode can be connected
An area can be open for one and congested for the other, so check the grade that matches your project type.

​
Layers and history

Use the layers panel to switch between consumption and feed-in, and the timeline to scrub through past snapshots and see how an area’s grade has moved over time.
