The favorable half of Germany: wind-rich, generation-surplus, and the origin end of the SuedLink corridor. A large load here sits where the power is, not where it is stranded.
See live grid data →50Hertz publishes a table of how much additional LOAD, not only additional feed-in, each existing substation in its control zone can host, together with an assessment of switchgear bay availability against bays already occupied or requested. This is directly load-side evidence rather than a generation heatmap. From 1 April 2026 the four German TSOs allocate large-consumer connection capacity by a maturity test (Reifegradverfahren) instead of first come first served, against a backdrop of 717 applications and roughly 270 GW requested by the end of Q3 2025.
How to check for your site: Read the 50Hertz substation table for additional load capacity and bay availability at the candidate location, then test the project against the maturity criteria, since capacity is no longer allocated by application date.
Why: Northern Germany has surplus wind but the binding constraint is grid access, which the national data-centre strategy (18 March 2026) names as the decisive factor for 2026 to 2030; the Energy Efficiency Act requires 100 percent renewable balance-sheet coverage from 1 January 2027 and waste-heat reuse. Hamburg and the north sit closer to generation than the fully allocated southern hubs.
What would change the read: SuedLink and northern grid reinforcement converting surplus wind into firm, connectable capacity for large loads.
Better access: the north hosts surplus generation and spare network capacity, though export south is constrained until SuedLink; connection is workable.
Strong availability: onshore and offshore wind run a surplus, with frequent curtailment when the south cannot absorb it.
Cost is the national wholesale price: Germany is a single bidding zone, so the north shares the same price as the south (its advantage is physical, not price).
Lower momentum than Frankfurt: less revealed data-center build so far, though growing near the coastal cable landings.
Cleaner power locally: wind-heavy generation gives the north a lower carbon profile than the gas-and-import-leaning south.
Germany's delivery reliability is world-class (about 12.8 minutes average interruption in 2023), and the north runs a generation surplus.
Average customer interruption (SAIDI) of 11.7 minutes per year in 2024, excluding major event days as filed.

We have not compiled what firm service actually promises here: whether it is firm, non-firm or interruptible, the conditions under which you can be curtailed, the redundancy required of you, and the transfer time behind any N-1 commitment. Treat this as an open diligence item, not as an indication that service is firm.
Utility feeds, UPS, storage, on-site generation, islanding, black start and the residual energy you still expect to lose are properties of a specific site design, not of a market. This layer only exists once there is a site, and we never assert it for you.
What this means: The supply crunch looks likely to ease for a new load energizing here in the coming years.
The average customer loses about 11.7 minutes of power per year (2024). This is the standard regulator outage measure (SAIDI); lower means a more reliable grid.

The northern zones carry Germany's wind surplus and are the favored siting region, but the transmission grid that moves that power is congested and new high-voltage links carry lead times of about 8 to 12 years. Access is easier than the south in principle, still multi-year in practice.

A large German load pays the wholesale price plus substantial grid fees and levies. The northern zone is the cheaper of the two German bands because it is closer to wind generation and less network-constrained.
