Grid congestion delays RIVM move and blocks power for 55,000 Brabant homes: what it means for internationals

The Netherlands' overburdened electricity grid is now causing problems far beyond housing construction. The country's public health institute, the RIVM, has been forced to delay its move into a brand-new, energy-neutral headquarters at Utrecht Science Park until after 2026 because the building cannot draw enough power from the grid. Instead, the institute will rely on gas-powered generators — the exact opposite of what the building was designed for.

At the same time, grid operator Enexis announced on 4 October that at least 55,000 planned homes in the province of Brabant cannot be connected to the grid at all, with no clear timeline for when capacity will free up. Nationwide, Netbeheer Nederland reported that nearly half of the power connection applications for 600,000 planned homes over the next three years cannot be accommodated.

What happened at the RIVM?

The RIVM's new 80,000-square-meter, 18-story tower at Utrecht Science Park was completed in April 2026. It was designed to be hyper-sustainable and energy-neutral, running entirely on green energy. But due to severe grid congestion in Utrecht — where grid operator Stedin imposed an infrastructure freeze in July — the building cannot secure enough electricity for its high-containment medical and scientific laboratories. Sicco Louw, the RIVM's Director of Operations, told RTV Utrecht: “We must have a full guarantee that the power the RIVM needs will be delivered. If the labs fail, we have a massive problem.”

The institute will now use large gas-powered generators and an industrial energy pack to limit peak demand on the public grid. RIVM officials called it a last-minute scramble, admitting: “We had not accounted for this in what is supposed to be a completely sustainable building.” Stedin representatives noted the painful contradiction as the Netherlands tries to transition away from gas.

55,000 homes stuck in Brabant

Enexis, the grid operator for the southern provinces, reported on 1 October that it received applications for 140,000 new homes nationwide. Before new rules took effect on 1 July — which barred operators from reserving capacity for small users — it also received another 60,000 ordinary applications for new or higher small-user connections. Capacity was found for 54,000 homes, but at least 55,000 are left stranded.

Rutger van der Leeuw, director at Enexis, called the number “considerably larger than we had expected.” He stressed that the homes can still be built — the question is when they can be connected. He outlined three solutions: reinforcing the grid with more cables and substations; building homes that require less energy or use power at different times (e.g., via home batteries); and making agreements with large industrial users to shift their energy use. In Maastricht, a paper mill adjusted its processes to free up capacity for 3,500 homes.

What does this mean for internationals?

If you are an international living in the Netherlands or planning to move here, these developments have direct consequences:

• Housing: If you are looking to buy or rent a newly built home, especially in Brabant, Utrecht, or the Brainport region (around Eindhoven), your move-in date could be delayed — possibly by years — because the home cannot be connected to the grid. Always ask the developer or landlord whether a power connection has been secured.
• Residence permits: Delays in housing construction do not affect your residence permit application directly, but they can complicate your ability to find suitable housing within the deadlines required by the IND (Immigration and Naturalisation Service). If you need to register at a new address within a certain time, a delayed connection could cause problems.
• Public health: The RIVM is responsible for infectious disease control, vaccination programmes, and public health research. Delays in its move could affect the institute's operational efficiency, though it continues to function from its current location. For now, there is no direct impact on health services for residents.
• Energy costs: Grid congestion may also lead to higher energy prices in congested areas, as operators invest in grid reinforcements and alternative solutions. Internationals on fixed rental contracts may not see immediate changes, but those in variable-rate energy contracts could face higher bills.

What can you do?

• If you are planning to buy a newly built home, check with the developer whether a grid connection has been reserved. Ask the municipality (gemeente) about local grid capacity.
• If you are renting, ensure your rental agreement includes a clause about grid connection timelines.
• For residence permit-related housing deadlines, contact the IND or a legal advisor if you anticipate delays.
• Stay informed via your local grid operator (e.g., Enexis, Stedin, Liander) about congestion in your area.

The bigger picture

Netbeheer Nederland expects that more than half of the housing project applications can eventually be connected, but the situation varies by region and even by substation. Grid expansions, smarter usage, and changes to project schedules could free up capacity. But for now, the message from grid operators is clear: the Netherlands cannot keep up with the demand for electricity, and both public infrastructure and housing are caught in the bottleneck.
