Grid congestion now reaches small consumers: what 1 July changes

The queue just got a lot longer

For years, grid congestion in the Netherlands was a large-consumer problem. If you were connecting a substation, an industrial plant or a battery park, you knew about the waiting list. If you were a household, a shop, a small workshop or an office fit-out, you were shielded. Small consumers, meaning everything up to a 3x80 ampere connection, received reserved capacity almost automatically, and your connection was granted quickly.

From 1 July that protection ends. As Netbeheer Nederland has set out, small consumers now join the same national queue as everyone else. New connections and connection upgrades for households and small businesses can face the same waiting times that industrial developers have lived with for years. There is one important nuance. If you do not need additional electricity, nothing changes for you, and your existing connection keeps working exactly as before. The change bites when you want more power: a heat pump, a charging point, an extra production line, an electric oven, a new building.

The scale is not small. Reporting on the pre-1-July queue put the number of large consumers already waiting for an upgraded connection at roughly 15,000. Adding small consumers to the same list does not make the copper in the ground grow any faster. It redistributes access to it.

Why the rules changed

The old system produced what the regulator politely calls "socially undesirable situations." Because small consumers had guaranteed priority, a chain of pharmacies could reserve capacity ahead of a hospital extension, or a string of small connections could quietly consume the headroom a school or a public-transport depot needed. Everyone followed the rules, and the outcome still made no sense.

So the Authority for Consumers and Markets (ACM) built a single prioritisation framework that applies to large and small requests alike. Instead of "who is small" or "who asked first," the queue is now ordered by what a connection is for. In simplified terms there are three priority groups: congestion relievers (parties that free up capacity, such as energy-storage operators, for connections above 3x80 A); safety and acute care (police, fire services, defence and acute healthcare, across all connection sizes); and basic societal needs (public transport, education, and, added from 1 July, housing construction).

There is also a transition window. Between 1 July and 1 January, freed-up capacity is reserved first for congestion relievers and for safety and healthcare, before the rest of the queue is served. Techniek Nederland has published a clear walkthrough of what this means in practice for installers and their clients.

The honest summary is that the constraint was never a shortage of clean electricity. The Netherlands has plenty of generation and plenty of demand. The constraint is transport capacity, meaning the ability of the wires, transformers and substations to move power from where it is made to where it is used at the moment it is needed. That is a physics and engineering problem, and it does not disappear because the rules were rewritten.

What this actually means if you are building something

If you are a developer, an industrial operator, a facility manager or a municipality with plans that need more power, three things follow from 1 July.

First, your connection is now a project risk, not an administrative formality. It belongs on the critical path next to permits and long-lead equipment, with its own owner and its own timeline. Assuming it will just be there is the fastest way to have a finished building that cannot be switched on.

Second, the answer is rarely to wait for more copper. Grid operators are expanding the network as fast as they physically can, but reinforcement runs years behind demand. The projects that get connected in the meantime are the ones that can show the grid operator they will not make congestion worse, or that will actively help.

Third, how well you understand your own electrical installation now has direct commercial value. The question is no longer only how much power do I want. It is how much power do I really need, when, in what pattern, and how much of my apparent demand is peaks I could shape, shift or supply myself. Answering that well can be the difference between a connection this year and a connection in 2030.

Where the engineering comes in

This is the part most of the public conversation skips. Getting connected under congestion sounds like a policy or a subsidy question. In practice it is an electrical-engineering and energy-modelling question, and the quality of that work decides the outcome.

At APARA we start from how the electrical asset behaves in reality, not on the nameplate. A motor does not draw its rated current the moment it starts. It has an inrush, a ramp, a start-up sequence, a duty cycle. A process has peaks that last minutes and baseloads that run for months. A charging hub, a battery, a heat pump and a production line each have their own signature in time. Load-flow, short-circuit and dynamic studies turn those signatures into a model that reflects the plant as it truly runs, rather than a conservative sum of maximum ratings that reserves capacity nobody will ever use.

Build that model honestly and something useful happens. The gap between contracted capacity and actually required capacity becomes visible. That gap is where the room to manoeuvre lives. It is where you find out whether your real constraint is a number on a contract or a handful of coincident peaks, and whether those peaks can be flattened, moved, or covered from your own side of the meter.

We are deliberately not laying out the specific solution here, because there is no single one. It depends on your site, your sector, your load profile and your timeline. What is constant is the discipline behind it. Understand the asset as it behaves in time, put every real constraint into a validated model, and design so that not a single electron of available capacity is left unused. Get that right and a full grid area often turns out to have more room than the connection request first suggested.

The transition is engineering work

The Netherlands will keep electrifying. Industry, mobility, heat and housing all point the same way. The grid will keep being the bottleneck for years. That in-between period, where demand is real and copper is scarce, is not solved by waiting. It is solved by engineering: grid integration, protection, dispatch interfaces, SCADA and energy management, and honest energy models that respect how plants actually run.

That is precisely the E&I&A scope we work in. If your project is on a connection waiting list, or you are weighing your options before you even apply, the earlier the electrical engineering starts, the more room you tend to find.
