New connections and expansions to the power grid are no longer possible in Mierlo and are limited in Geldrop
The available transmission capacity at these substations in the area shaded in red (map) is at full capacity. Starting July 1, 2026, Enexis will no longer be able to provide any new connections to the power grid in these areas. This means that new homes, schools, healthcare facilities, etc., can no longer be connected, and further business growth will be constrained. Furthermore, upgrading an existing connection—sometimes necessary for a heat pump or charging station—will no longer be possible in these areas.
Impact on Geldrop-Mierlo
As a result, there will be no new power available in Mierlo for the time being, starting July 1. We are, of course, assessing the implications of this situation. We will evaluate this on a project-by-project basis. In Geldrop, power availability is limited.
What does this mean in practical terms for Mierlo?
- New homes cannot be connected.
- Companies are unable to establish themselves or expand.
- Households are unable to make their homes more sustainable.
- It is no longer possible to upgrade existing connections—for example, for a charging station or a heat pump.
Do you have questions about your electricity connection, or would you like to make changes to it? If so, please contact the utility company at. In Geldrop-Mierlo, that is Enexis.
Priority on the full power grid
If capacity does become available somewhere, it will be allocated based on what is known as “social prioritization.” To this end, new national rules for allocating available capacity on the grid will take effect on July 1, 2026. These rules have been drafted by the regulator, the Netherlands Authority for Consumers and Markets (ACM). This means that certain applications will be given priority. Examples include hospitals, drinking water companies, and fire stations. Next in line are housing projects, schools, and heating projects, among others. See below for:
How does the power grid work?
The power grid consists of three parts: the high-voltage grid, the medium-voltage grid, and the low-voltage grid. Businesses that require large amounts of electricity are connected to the high- and medium-voltage grids (these are large-scale consumers). Small businesses, homes, and public facilities are connected to the low-voltage grid (these are referred to as small consumers). The high-voltage grid is managed by TenneT. The medium- and low-voltage grids are managed by regional grid operators. In Geldrop-Mierlo, that is Enexis.
What exactly is going on?
The power grid is overloaded. This means that the power lines and substations can no longer handle any more electricity.
The power grid can become overloaded in two ways:
- if everyone needs electricity at the same time, causing demand to exceed the grid's capacity
- if too much solar energy is generated at once and more electricity is fed back into the grid than it can handle.
In our region, we are experiencing congestion in both electricity consumption and supply. The power grid is under heavy strain on both sides, leading to congestion at times when there is high demand for or supply of electricity. This occurs mainly during peak hours, between 4:00 p.m. and 9:00 p.m.
Impact on residents
Starting July 1, 2026, there will no longer be enough electricity for existing homes and other small consumers in Mierlo and, to a limited extent, in Geldrop. Making your home more sustainable by switching to a (hybrid) heat pump or electric cooking will no longer be a straightforward option. This also applies to the installation of solar panels. Additionally, on very sunny days, solar panel inverters may sometimes temporarily shut down to prevent the local neighborhood grid from becoming overloaded. During these times, you cannot feed power back into the grid, nor can you use the electricity you generate yourself. The inverter usually switches back on automatically once the risk of overload has passed.
Please contact the Energiehuis Slim Wonen at for more information about other ways to make your home more sustainable.
A heat pump, an induction cooktop, a home charging station. Are you planning to use more electrical appliances? If so, you’ll often need an additional circuit in your electrical panel. Sometimes a higher-capacity electrical connection is required. First, have a certified electrician assess the capabilities of your existing connection. Starting July 1, a waiting list will be in effect in Geldrop-Mierlo. You can check whether this applies to your home using Enexis’s power grid checker.
Check your utility connection with Enexis
If we don’t take action now to address the overloaded power grid, we may see lights flickering in homes in the future, or—in the worst-case scenario—power outages affecting entire streets, neighborhoods, or districts. We don’t yet know if or when that will happen. Together with grid operator Stedin, we’re working to ensure that there remains sufficient power for both new and existing homes. You can, however, prepare yourself for a possible power outage. For more information, visit:
What are we going to do about this?
Grid operator TenneT is actively working to expand the power grid by building additional high-voltage and electrical substations and laying cables. This will take years. In our region, TenneT is working on reinforcing the 150 kV connection between Eindhoven-East and Maarheeze and constructing a new 380 kV overhead high-voltage connection between Maasbracht and Eindhoven.
And together with Enexis, we will be installing additional electrical cabinets over the next few years. This neighborhood-based approach is a major undertaking; streets will need to be dug up to make this happen. We are assisting the grid operators wherever possible.
More measures are in the works and are currently being finalized.

What can you do yourself?
We also need to use our electricity more efficiently. For example, by avoiding situations where we all use a lot of electricity at the same time. Would you like to do your part and help prevent the power grid from becoming overloaded? Then check out these tips:
- Saving energy is always a good idea. Visit EnergieHuis Slim Wonen at to find out how you can easily save energy.
- Use as little electricity as possible during peak hours, between 4:00 p.m. and 9:00 p.m. On the Enexis website, you can see when the power grid is under heavy load.
- Do you have solar panels? Try to use the electricity you generate right away. For example, do your laundry during the day or when the sun is out.
- Do you have an electric car? If so, charge it before 4:00 p.m. or after 9:00 p.m. Even if it’s sunny and you have solar panels, that’s a good time to charge.
- Are you thinking about buying a heat pump? A hybrid model puts the least strain on the power grid, because it switches to gas from the furnace on cold days.
- Are you thinking about buying a home battery? Home batteries actually cause an additional surge on the power grid. Be sure to research the risks thoroughly beforehand, such as fire safety and costs. We do not offer loans or subsidies for home batteries.
