Netbeheer Nederland expects that in 2035 around 800,000 households will be connected to a low-voltage grid with an elevated risk of faults. This is a forecast after planned grid upgrades, not a prediction that all these households will lose power.
The warning comes from a new system analysis of the low-voltage grid. According to the analysis, the number of households in an area with an elevated risk of faults will rise from around 400,000 now to approximately 800,000 in 2035. This amounts to about 9 per cent of all households, according to the notes accompanying the analysis.
Up to 2030, solar panels are the main source of bottlenecks on the low-voltage grid, according to Netbeheer Nederland. At sunny times, large amounts of electricity can be fed back into the grid simultaneously, causing voltage to rise. Inverters may then switch themselves off. This is not the same as a nationwide power cut, but it can mean that households temporarily export less solar power.
After 2030, the focus of the forecast shifts. Heat pumps and charging points mainly increase demand for electricity during the evening peak. This can place greater strain on transformer substations and cables. For 2030, the analysis still identifies around 4,000 bottlenecks at transformer substations and 1,700 bottlenecks in connecting cables, despite planned expansion.
The figures are not entirely negative. Netbeheer Nederland says the expected number of capacity and voltage bottlenecks up to 2035 is lower than in the problem analysis from 2024. According to the new assumptions, the growth in the number of households with solar panels will be lower than previously thought. This reduces some of the pressure, but does not remove the structural challenge.
The grid operators therefore point to a combination of measures. Alongside expanding cables and substations, they mention better visibility of behind-the-meter devices, technical requirements, flexible electricity use and price incentives at busy times. There is not yet any general registration system for charging points and heat pumps, as there is for solar panels.
For households, the forecast mainly means that the consequences may vary locally and technically. In a busy area, a charging point may temporarily be less available or an inverter may switch off. It is not possible to infer from the national figure whether a specific address is at risk. Local grid data and planned investment are decisive in that regard.
The analysis thus highlights a policy dilemma. The Netherlands wants to expand solar panels, electric cars and heat pumps rapidly, but that growth also requires investment, better management and agreements on who provides data and flexibility. The choice between building faster, managing demand more intelligently and using stronger price incentives ultimately lies with politicians and regulators.
One story, several perspectives
What is established
- Netbeheer Nederland expects around 800,000 households to be connected to a low-voltage grid with an elevated risk of faults by 2035.
- According to the analysis, solar panels are the main source of bottlenecks up to 2030, after which the focus shifts towards charging points, heat pumps and other causes.
- The analysis identifies grid expansion, registration, technical requirements and flexible electricity use as possible solutions.
Left
Arguments The government must continue investing heavily in grid upgrades and spread the costs widely. Households must not be penalised for policies that have encouraged the transition to clean energy. Flexibility can help, but must not mean that people with solar panels, a heat pump or an electric car bear the costs and inconvenience alone.
Values Collective responsibility, affordability and rapid decarbonisation.
Consequences Greater public investment and protection for households could make the transition fairer, but would require higher government spending and possibly higher network charges.
Centre
Arguments A combination of measures is the obvious course: expand cables and transformer substations, improve the registration of devices and shift usage at peak times voluntarily or through contracts. Clear rules are also needed on data, compensation and the reliability of automatic management.
Values Feasibility, reliability and a balance between public and private responsibility.
Consequences A mixed approach could spread the pressure, but would require time, oversight and complex agreements with millions of households.
Right
Arguments Scarce grid capacity should be allocated more strongly through prices and market incentives. Those who demand a great deal of capacity at busy times should pay more for it. The government should set the framework and speed up permits, but be cautious about broad subsidies and compulsory switching-off.
Values Cost awareness, freedom of choice and efficiency.
Consequences Stronger price incentives could encourage investment and smart use, but could hit households with less financial room relatively harder.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

Editor's note
The 800,000 households are a model-based forecast for 2035, not a count of current outages. The analysis also presents fewer bottlenecks than in 2024; local consequences for individual households cannot be established.Sources
