The Netherlands is grappling with one of Europe's most acute electricity distribution crises. Liander and Enexis — the country's two largest distribution system operators (DSOs) — have publicly asked consumers and renewable energy producers to adapt their behaviour. According to Liander, approximately 7,300 customers are waiting longer than expected to upgrade from a small-consumer connection to a more powerful one, directly blocking those wanting to install heat pumps or EV charging stations.
What are grid operators asking solar owners to do?
In 2025, Enexis invested a record €1.9 billion in new grid infrastructure, unlocking 542 MW of additional flexible capacity — equivalent, according to van der Leeuw, to the annual electricity consumption of a city the size of Eindhoven. The expansion included flexibility contracts, congestion management tools, and pilot projects for centrally controlling hybrid heat pumps, which reduced evening peak loads by 10–25%.
New rules from July 2026
The Dutch situation is a preview of challenges other densely solar-equipped European countries — including Germany, Spain, and Belgium — may soon face. For solar and heat pump owners across Europe, the takeaway is clear: smart self-consumption, overnight EV charging, and flexible feed-in are no longer optional extras but increasingly central to how distributed energy systems will function.

How Much Do Solar Panels Produce in Winter? Realistic Numbers
Winter output from a rooftop solar system is a fraction of the summer peak: shorter days, a low sun, cloud and snow mean that the four darkest months together typically deliver only around a tenth to a fifth of the annual yield, depending on latitude. This guide sets realistic month-by-month expectations, explains what winter means for self-consumption and your bill, shows how a battery and smart scheduling help, and why you should never size a system for December.
Pre-Season Heat Pump Checklist: What to Check in September
A heat pump does most of its work in the coldest months, but how much electricity it burns doing so is largely decided in September. Here is what homeowners can check themselves, from the outdoor unit to the heating curve, what to leave to a qualified engineer, and how to get the most out of rooftop solar in the autumn months.
Air conditioning on solar power: what summer cooling really costs in 2026
In a heatwave, air conditioning becomes one of the biggest loads in a household — exactly when solar panels produce the most. We look at what cooling costs with and without solar, how much extra capacity you need, and what to watch for when sizing a system.
Heat Pump, Solar & H Tariff: How to Plan Together
Combining a heat pump, rooftop solar panels and a preferential electricity tariff can significantly cut household energy bills — but only if you plan all three as one integrated system. This guide walks through the decision logic, common mistakes and key considerations for homeowners.
