Groningen grid status

The numbers

Stations and areas

• Province overview, directional: Every Groningen service area Wattlas sampled on 5 July 2026 shows TenneT's off-take layer at a less constrained level (code 1) while the feed-in layer is at its most constrained level (code 3), except Eemshaven and Delfzijl where both layers have room. This is the reverse of the congested south: off-take generally has headroom, feed-in is the binding constraint. Expected: Feed-in relief runs through the large TenneT northern build-out (Eemshaven Oostpolderweg 2034 to 2037, Farmsum Oosterlaan 2032 to 2035, Vierverlaten 2034 to 2036), so these three span 2032 to 2037; related regional works in the same programme run to 2039. source
• Delfzijl (Weiwerd) service area, feed-in: The capacity map (sampled 5 July 2026) lists 509.1 MW existing against 399.7 MW required feed-in capacity with an 83.1 MW feed-in waiting queue, the largest in the sampled Groningen areas, on an industrial-scale grid (off-take existing 518 MW). TenneT code 0 both layers here, so the constraint is regional feed-in capacity rather than transmission. Expected: TenneT Farmsum Oosterlaan 220/110 kV (2032 to 2035) and Eemshaven Oostpolderweg 380/110 kV (2034 to 2037); Enexis expands Weiwerd. source
• Veendam service area, feed-in: The capacity map (sampled 5 July 2026) lists 154.7 MW existing against 107.8 MW required feed-in capacity with a 62.6 MW feed-in waiting queue, TenneT feed-in code 3, regional solve indicated 2029. Off-take has room (existing 155.4 against 61.5 required). Expected: Regional feed-in solve indicated 2029; TenneT Meeden-Winschoten 110 kV and Gasselte-Veendam works 2029 to 2037. source
• Eemshaven service area, both directions: The capacity map (sampled 5 July 2026) lists 149.8 MW existing against 70 MW required off-take (queue 0.1 MW) and 155.5 MW existing against 123 MW required feed-in (queue 0 MW), with TenneT off-take code 1 and feed-in code 0. Eemshaven has room in both directions, unusual for the north, and carries the largest TenneT build-out: a new Eemshaven Oostpolderweg 380/110 kV station. Expected: New TenneT 380/110 kV station Eemshaven Oostpolderweg (2034 to 2037) and Farmsum Oosterlaan (2032 to 2035). source

As of 2026-07-05. All MW figures come from the official Netbeheer Nederland capacity map, sampled 5 July 2026, carrying that peildatum; existing, required and queued capacity are the map's published per-service-area figures. The directional flip (off-take room, feed-in constrained) is confirmed across the sampled areas. Enexis build-out figures come from Enexis' own press release of 31 October 2025. TenneT project dates are from the capacity map projects layer, all indicative operator timelines. Enexis is the sole regional grid operator for the sampled Groningen areas.
