All 12 provinces compared
Generated from the same data as the cards above: status per direction, the constraint in one line where it is source-backed, an indicative relief date where the source gives one, and the date Wattlas last verified the province. Empty cells mean the figure is not yet source-locked, not that the answer is zero.
| Province | Off-take | Feed-in | Key constraint | Indicative relief | Last verified |
|---|---|---|---|---|---|
| Drenthe | Partial | Congested | Feed-in across the province: the transmission grid has off-take room while feed-in is at its most constrained level. The largest feed-in waiting list sits at Emmen (about 71 MW), with Norg around 46 MW. | 2026 to 2036, indicative | 2026-07-05 |
| Flevoland | Watch | Watch | Not yet source-locked | Not yet source-locked | 2026-07-03 |
| Friesland | Watch | Watch | Not yet source-locked | Not yet source-locked | 2026-07-03 |
| Gelderland | Watch | Watch | Not yet source-locked | Not yet source-locked | 2026-07-03 |
| Groningen | Partial | Congested | Feed-in across most of the province: the transmission grid has off-take room while feed-in is at its most constrained level in most sampled areas. The largest feed-in waiting lists sit at Delfzijl (about 83 MW) and Veendam (about 63 MW). | 2032 to 2037 for the three named stations, indicative; related regional works run to 2039 | 2026-07-05 |
| Limburg | Congested | Congested | Both directions across the province: every sampled service area is at TenneT's most constrained transmission level for off-take and feed-in. The heaviest off-take waiting queues sit in the industrial south (Maastricht, the Chemelot cluster area) and in Venlo. | Planuitwerking 2026 to 2029, realisatie 2029 to 2033, ingebruikname 2031 to 2034, indicative | 2026-07-05 |
| Noord-Brabant | Congested | Partial | Off-take in most of Brainport: only 3 of 7 studied service areas (Best, Eindhoven Zuid and Maarheeze) are green or yellow, regional headroom, on the official capacity-map colour scale, and the TenneT transmission layer is structurally full, which keeps stations like Hapert red regardless of regional relief. | Early 2030s | 2026-07-05 |
| Noord-Holland | Watch | Watch | Not yet source-locked | Not yet source-locked | 2026-07-03 |
| Overijssel | Congested | Congested | Both directions across Twente and the Zwolle corridor: every sampled service area is at TenneT's most constrained transmission level for off-take and feed-in. TenneT states Zwolle-West and the Enschede subnetwork have no room until 2035. The largest feed-in queue sits at Almelo (about 39 MW), the largest both-direction pressure at Zwolle. | 2027 Hengelo; 2033 to 2038 structural, indicative | 2026-07-05 |
| Utrecht | Partial | Partial | New and heavier off-take connections in area 1a (Utrecht city, Woerden, De Ronde Venen, Zeist, Houten) are paused from 1 July 2026 until grid expansion or freed capacity becomes available. Feed-in is constrained at the TenneT layer across the province, and regionally in Nieuwegein and Houten Oost. | End of 2031 for the most critical expansions if all goes to plan; 2033 expected; 2035 with setbacks | 2026-07-04 |
| Zeeland | Congested | Partial | Off-take across almost the whole province: TenneT's high-voltage grid has been at maximum capacity since the summer of 2023, and parts of Stedin's regional grid (among others Walcheren Noord) are full on top of that. Feed-in is congested in parts of the province, with mandatory congestion management above 8 MW in the Noordring. | 2030 to 2031, indicative | 2026-07-04 |
| Zuid-Holland | Congested | Watch | Off-take across almost the whole province: TenneT's high-voltage grid has reached maximum capacity across nearly all of it, and parts of Stedin's regional grid are full as well. On 1 July 2026 Stedin added station-level congestion announcements for Hellevoetsluis, Europoort and Wellebrug (25/10 kV), each stacked inside the TenneT constraint. The Rotterdam harbour remains the sharpest case. | 2032 to 2035 | 2026-07-04 |
