TenneT's grid connection map, explained
Ten substations with possible new connections for large consumers, five of them in Lower Saxony. What the map shows and what it does not.
Since 1 April 2026, TenneT has published a map of the substations where, under the current procedure, new connections for large consumers are possible. Across the entire German TenneT control area there are ten. Five of them lie in the northwest of Lower Saxony, with expected commissioning dates between 2030 and 2033. No classic power plant node is listed as available.
What does that mean? First: the time to connection is no longer counted in years from the date an application is filed, but by the maturity of the project. Second: whoever secures land at one of the listed substations and prepares the zoning has a measurable advantage in the procedure. Third: the map does not show how much capacity is available per substation or how many storage applications are already pending. Only a conversation with the grid operator answers those questions.
For municipalities, the map means this: if one of the listed substations sits in your municipal area, you should know which plots border it and who owns them.
