The constrained half: the FLAP-D hub (Frankfurt) and Bavaria's industry sit on the importing side of a bottlenecked grid, having lost most of their nuclear in 2023. The highest demand meets the tightest supply, which is where the reliability overlay bites.
See live grid data →TenneT publishes a control-zone map of currently identified locations for possible new connections, with an indicative substation, an estimated in-service date, and notes on local limitations. That covers the Munich side of this market. Frankfurt sits in the Amprion control zone, for which we have not established an equivalent publication, so coverage here is partial and stated as such. The same national maturity test (Reifegradverfahren) applies from 1 April 2026.
How to check for your site: Check the TenneT connection-location map and its in-service dates for the candidate site. For a Frankfurt-area site, approach Amprion directly: no equivalent published position is established in our evidence.
Why: Frankfurt's transmission is fully allocated for years and new load is pushed to ex-coal corridors, but the SuedLink link (around 2028) and grid reform are underway.
What would change the read: SuedLink completing and the southern grid de-bottlenecking so core-hub access reopens.
For new supply: New supply is pulled toward ex-coal corridors and the north; SuedLink (around 2028) is the structural unlock for moving that power south.
Beyond the grid: Efficiency permitting adds a hard design constraint: under the Energy Efficiency Act, data centres commissioned from July 2026 must reuse a rising share of waste heat (toward 20 percent by 2028) or feed district heating, with fines up to 100,000 euros for non-compliance. White & Case Columbia Climate Law
Constrained access: a demand centre that depends on northern and imported power over congested corridors; connection is planning-heavy until SuedLink (about 2028).
Tighter availability: the 2023 nuclear exit removed large southern baseload, leaving heavier reliance on gas, imports and redispatch.
Cost is the national wholesale price (single bidding zone), though the south bears more of the redispatch burden.
Highest momentum: Frankfurt anchors the FLAP-D cluster (about 750 MW), the continent's number-one hub.
Higher carbon: gas backup and imports lift the effective carbon of southern supply relative to the wind-rich north.
Delivery reliability is high nationwide (about 12.8 minutes average interruption in 2023); the concern here is forward firm capacity, not outages.

The south lost most of its nuclear baseload in 2023 and depends on northern and imported power over a bottlenecked grid; the SuedLink HVDC fix is delayed to about 2028, leaving heavy redispatch. Firm-capacity risk for a new large load is concentrated here.
What this means: A large new load should expect genuine exposure to forced power cuts (curtailment), price spikes, and delays in getting connected, and should design in backup power or firm supply contracts.

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 picture looks likely to tighten; a new load should lock firm supply early and expect competition for capacity.
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.

Frankfurt, Europe's largest data-center hub, has its transmission interconnection fully allocated for years ahead, and the industrial south leans on northern power over a bottlenecked grid until SuedLink completes around 2028. Developers are moving to the Aachen-Cologne-Dusseldorf corridor and brownfield coal sites where capacity exists. Core Western European connection timelines run about 7 to 10 years.

The southern German band sits above the north because the south is further from wind generation and carries heavier network-constraint and redispatch costs, which flow through to a large load's delivered price.
