Ireland restricts Dublin data centre connections (2021)
Data centres grew to consume a large and rising share of Ireland's metered electricity, most of them clustered around Dublin. In late 2021 the energy regulator directed the grid operator to stop offering new connection agreements to data centres in the Dublin region while it reviewed the problem.
New Dublin projects stalled and developers looked to other regions and countries.
Ireland became the standard example of grid capacity, not demand, as the binding constraint on data centre growth, and connection rules became the main policy lever.
Norway is applying the same lever: freezing the queue rather than banning the industry, on the argument that the local network cannot carry what has been requested.
