Grid Congestion in the Netherlands: Why a Home Battery Is the Solution

What is grid congestion and why is the problem growing?

Grid congestion occurs when the demand for transport capacity on the electricity grid exceeds the supply. This is not a new phenomenon, but the problem is growing exponentially due to the simultaneous increase of solar panels, electric vehicles, heat pumps and home batteries. Grid operators such as Enexis, Alliander and Stedin report that the grid is full in some regions.

For homeowners, grid congestion has direct consequences: restrictions on feed-in, longer connection waiting times and in extreme cases a temporary feed-in ban. A home battery offers an elegant solution here.

How does a home battery contribute to grid relief?

A home battery reduces peak load on the grid in two ways:

Peak shaving

Instead of feeding generated solar power directly back to the grid (which contributes to congestion), a home battery stores the power for your own use later in the day. This significantly reduces peak feed-in in the afternoon and relieves the local grid.

Demand response and smart charging

With a dynamic energy contract, the battery charges at times of low grid load — typically at night or early in the morning. This also applies to EV chargers in combination with a home battery. The result: lower electricity costs and a contribution to grid balancing.

What can you do yourself?

As a homeowner with solar panels, you can actively contribute to grid relief and benefit financially at the same time:

• Install a home battery: store solar power for your own use instead of feeding back during peak times
• Choose a dynamic contract: automatic charging at low grid load delivers a double benefit
• Use an EMS (energy management system): automatically optimises when you charge, feed in and consume
• Enable sharing mechanisms: some grid operators offer compensation for demand response via certified aggregators

Regional congestion: check your situation

The extent of grid congestion varies considerably by region. Below is an overview of the most affected areas in 2026:

Financial benefits with grid congestion

In areas with active congestion issues, some grid operators offer congestion subsidies for households that actively contribute to grid relief. These are per-kWh compensations that you can deploy flexibly. Ask your grid operator about available schemes in your postcode area.

GOPACS market for flexibility

Via the GOPACS platform (Grid Operator Platform for Congestion Solutions), energy companies and aggregators can purchase the flexibility of home batteries. Some energy suppliers already offer households the opportunity to participate in this market via a contract — with an additional compensation on top of the normal energy revenue.

Congestion zones and future legislation

The Energy Act 2024 increasingly requires grid operators to invest in grid reinforcement and in smart demand management. It is expected that home batteries with grid relief functionality will receive additional subsidies in the coming years, both nationally and provincially.

Conclusion: from problem to opportunity

Grid congestion is a societal problem that is growing rapidly. But for the savvy homeowner, it also presents opportunities: higher compensation for flexibility, additional subsidies and an increasing value of energy independence. A home battery is the key player here.
