The electricity grid capacity map of the Netherlands consists of three layers:

• Overview page that provides a comprehensive view of the combined TSO & DSO (congestion) situation;

• TSO map layer with information on TenneT’s (congestion) situation (at the high-voltage level 110 kV and 150 kV);

• DSO map layer with information about the (congestion) situation at the regional grid operators (at the medium-voltage level). 

On each layer, the situation for demand or infeed can be selected. The capacity statuses for different areas is visualised with different colours.

Grid hosting capacity is currently indirectly (roughly deducible) published publicly on bottleneck aggregation level for voltages ≥10 kV. The supplied overview and corresponding data do not replace a formal grid integration test and are intended solely as a high-level overview of grid status. No rights can be derived from the published information. The derivation method of the grid hosting capacity is complex, contains several assumptions, and is not publicly available. The method and assumptions do, however, adhere as closely as possible to the principles and rules set out in the national Dutch grid regulation laws defined by the “Netcode” (https://wetten.overheid.nl/BWBR0037940).
