Glossary
Every Dutch grid term the app uses, explained in plain English. We keep the Dutch terms (they're what every operator and journalist here uses) and add the English equivalent next to each. For the full method, see methodology.
- ABC English: Restricted connection + transport contract
- Aansluit- en transportbeperkingen contract — a contract accepting peak-curtailment.
- The customer accepts that transport will be restricted during peak hours in exchange for an earlier connection. A common path forward in congested areas.
- Afname English: Consumption
- Drawing power from the grid — a consumer connection.
- The consumption grade measures how quickly a new consumer (data centre, factory, heat-pump cluster, EV hub) can be connected. Independent of the feed-in grade for the same area.
- ATR English: Connection + transport right
- Aansluit- en transportrecht — the right to both a physical connection AND guaranteed transport.
- Without ATR, a connection can physically exist but no energy can actually flow through it. The portfolio matcher offers a non-firm (ATR85) toggle that relaxes this guarantee for projects that can curtail.
- GVA English: Group reinforcement project
- Groepscapaciteit / Groepsverzwaring — a bundled upgrade of multiple feeding areas.
- A coordinated reinforcement that upgrades several feeding areas at once. The relief year shown on a region detail page often comes from a GVA schedule.
- Netcongestie English: Grid congestion
- Demand or supply exceeds the available grid capacity in an area.
- An area is ‘netcongestief’ when grid operators must refuse or postpone new connections and capacity expansions. Speed to Power expresses this as a grade of D, E, or F.
- Opwek English: Feed-in (also: teruglevering)
- Pushing power onto the grid — a producer connection.
- The feed-in grade measures how quickly a new producer (solar farm, wind project, battery in feed-in mode) can be connected. Often diverges significantly from the consumption grade in the same area.
- TenneT-cap English: Two-layer cap
- A high-voltage saturation that caps every DSO area below it at grade C.
- When the TenneT substation above a DSO area is congested, the DSO cannot promise local capacity even if its own MS-net has headroom. The grade is held at C until TenneT’s published relief year passes.
- Voedingsgebied English: Feeding area
- The primary geographic unit a DSO publishes a congestion view for.
- A geographic zone fed electrically by one substation or cluster. All Speed-to-Power grades are computed at this level first; municipality and postcode figures are aggregations on top.
