Grid operators publish map summarizing transmission capacity for solar power
The regional grid operators – including Enexis, Liander and Stedin – have jointly published a map showing whether transmission capacity is still available for solar energy in a given area.
This nationwide overview helps producers who want to apply for subsidies to produce renewable energy through the Sustainable Energy Production and Climate Transition Incentive (SDE++). Anyone who is going to produce sustainable electricity and applies for SDE++ subsidy to do so is required to send along a transmission indication. The system operator indicates in the transmission indication whether sufficient transmission capacity is available on the electricity grid at the chosen location.
Overall view was missing
The map, which can be accessed here, shows for the whole of the Netherlands where on the grid areas of the regional grid operators there is sufficient transmission capacity on the electricity grid to transport renewable electricity and where there is less or no more space on the grid. The card is intended for generators planning projects that supply energy to the grid through a large consumer connection, such as large solar roofs and solar farms.
Information TenneT lacks
On the map, producers can check for themselves in advance how likely it is that a transport indication can be issued. Regionally, such maps were already available and consultable through the various regional grid operators, but a comprehensive overview was lacking until now. Information on the map is currently limited to the possibility of supplying energy to the grids of the regional grid operators. Ways to integrate available capacity on the grids of national grid operator TenneT are being considered.
Red does not always lead to rejection
The information on the currently published map is considered indicative. For concrete plans, producers should always contact the relevant grid operator. In general, an application in an area that is not red will always result in obtaining a transportation indication. However, an application in a red area does not necessarily result in a rejection of the transportation indication; consideration is always given to when the congestion is resolved and how this fits with the project’s realization timeframe. The maps are updated regularly.
Meaning color codes
The color codes on the map have the following meanings:
- Transparent: no transport scarcity (yet)
- Yellow: transport scarcity is imminent, modified quotation regime applies
- Orange: advance notice of structural congestion to ACM
- Red: structural congestion, new requests for transportation will not be honored
