The connection capacity calculation app e-Gridmap:
- shows the approximate connection capacities in substations that can be used without increasing transmission lines’ service capacities
- calculates the estimated costs of additional investments for accommodating the desired connection capacity at a given substation
The results are set out when connecting to one substation and do not take into account a situation where connection capacity is desired simultaneously at different substations. In the 110 kV grid, the limit for calculations of connection capacity is 100 MvA; and in the 330 kV grid, it is 300 MvA. The calculations shown by e-Gridmap apply to cases where a new grid connection must be established for connecting to the grid.
The e-Gridmap data are updated once a quarter or more often, and the date of the last update can be seen in map view. For questions related to e-Gridmap, contact firstname.lastname@example.org
For more detailed information, such as the amount of connection fee, the expected time for completion of the connection and other technical requirements, the prospective customer must submit a pre-feasibility study application to Elering via the connection information system, egle.ee.
