Grid congestion in The Netherlands is highly localized: the last-mile wiring is at its limits, but higher up there is plenty of capacity. Furthermore, the congestion is time- and condition-dependent: people living in a home want 24/7 access to power, and want it to be reliable.

Some temporary dredging barge getting a high-voltage hookup, which is only running during sunlight hours, and whose operations can be vetoed by the grid operator at very little notice? Not a problem.
