More and more companies are noticing that the electricity grid in the Netherlands is reaching its limits. New connections are being refused or delayed, solar panels are not always allowed to feed back into the grid, and expansions require months or even years of waiting time. This situation is what we call grid congestion. Although it seems like a technical problem, it ultimately boils down to one question: how can your company continue to grow and become more sustainable while the grid is at capacity? In this article, you will read what grid congestion is exactly, why it occurs, what the consequences are for businesses, and how you can still create capacity with smart solutions — such as a smart EMS.
What exactly is grid congestion?
Grid congestion means that there is too little capacity on the electricity grid to simultaneously handle all demand and supply of power. There can be an overload when drawing power, or when feeding back into it. The grid operator must then take measures, such as refusing new connections or limiting existing ones. According to Netbeheer Nederland the number of regions with congestion is growing rapidly, especially in Gelderland, Noord-Brabant, Utrecht, and Friesland. Companies in these areas are finding that expansion plans or sustainability projects are delayed. Important to understand: grid congestion does not mean there is too little energy, but that the infrastructure — cables, transformers, and distribution stations — is not designed for today's peak usage.
How does grid congestion occur?
There are multiple causes that reinforce each other:
- Accelerated electrification: More and more companies are replacing gas and diesel with electric alternatives. This significantly increases peak demand.
- Sustainable generation: Thousands of companies are simultaneously generating solar and wind energy, which specifically causes overload during the day.
- Slow grid upgrades: Upgrading the grid often takes five to eight years due to permits, staff shortages, and material issues.
- Lack of flexibility: Everyone consumes or produces at the same times, leading to short, extreme peaks.
The result is that the grid is literally "full" in many places. The available capacity is not flexible enough to absorb peaks, meaning new connections or expansions have to wait.
Do you want to grow despite a full connection? With a smart EMS you optimize your capacity. You prevent peaks, increase your self-consumption, and structurally lower your energy costs. Read how it works in practice at how Zympler works.
What does grid congestion mean for businesses?
For businesses with growth or sustainability plans, grid congestion has direct consequences. According to Netbeheer Nederland thousands of companies are now on a waiting list for expansion or feed-in. This leads to:
- Operational limitations
Machines or charging stations cannot always operate simultaneously, which affects planning. - Higher costs
Peak loads lead to higher transmission tariffs and potential penalties for exceeding contractual values. - Delayed sustainability efforts
Solar panels or heat pumps cannot be optimally utilized without sufficient transmission capacity.
A concrete example: a logistics center with a charging plaza generates more solar power during the day than it can feed back into the grid. At the same time, consumption rises during the afternoon peak. Without smart control, overload occurs, leading to production loss or higher costs.
What does grid congestion cost your organization?
The financial impact of grid congestion is often greater than companies realize. There are three cost categories:
- Operational costs: Inefficiencies due to downtime or delayed production.
- Financial costs: Higher transmission tariffs during peak consumption.
- Missed revenue: E.g., solar panels selling their generated electricity at the lowest market price instead of supplying it to your own operations.
How can you smartly resolve congestion?
There are five practical strategies for resolving grid congestion that companies can implement right now:
- Peak shaving – flattening peaks with battery storage or smart software.
- Load shifting – shifting consumption to periods of lower grid load.
- Capacity Limiting Contracts (CLC) – discounts on grid costs in exchange for flexibility.
- Local storage and energy hubs – collaborating with neighbors to share or buffer energy.
- Solving grid congestion with smart control using an EMS – using data to automatically optimize consumption, generation, and storage.
More explanation on how a smart EMS makes this possible can be found in the description of how Zympler works.
How does a smart EMS work in practice?
A smart EMS (Energy Management System) acts as the brain behind your energy consumption. The system:
- Continuously measures consumption, generation, and storage.
- Predicts peaks based on data and weather information.
- Automatically schedules when devices charge, discharge, or pause.
- Controls assets in real-time, ensuring consumption stays within safe limits.
This makes it possible to prevent peaks without restricting operations. Think of a battery that charges at night to absorb peaks during the day, or charging stations that intelligently distribute across available capacity. A smart EMS works independently of hardware suppliers and can therefore be integrated with existing infrastructure. Zympler distinguishes itself through the simplicity and speed with which companies can reduce their peak load without complex implementations. View examples of smart EMS control for more insight.
Which strategy is right for your business?
The optimal approach depends on your profile:
- Offices and SMEs
Profit often comes from smart charging and utilizing solar power for self-consumption. - Logistics and transport
Large charging peaks require battery support and dynamic planning. - Industry and production
Focus on load shifting and integration with production processes.
It always starts with insight. Analyze quarter-hourly values, recognize patterns, and simulate scenarios. An EMS can then calculate the impact of each measure. This makes the step from insight to action concrete and measurable.
How can you start today?
You don't have to wait for grid reinforcement. The first steps are:
- Measure – map peaks and troughs using existing measurement data.
- Analyze – determine when and why peaks occur.
- Optimize – plan processes more intelligently or use flexible contracts.
- Automate – have an EMS control based on predictions.
- Collaborate – explore opportunities within business parks or energy hubs.
Grid congestion is not just a limitation, but also an opportunity to work smarter, more cost-effectively, and more sustainably. Companies that invest now in insight and control will be at the forefront of the energy market of the future.
Zympler provides smart energy management software that solves grid congestion, lowers energy costs, and supports growth.

Why are more and more companies choosing behind-the-meter batteries?
More and more companies are investing in behind-the-meter batteries. These are energy storage systems directly connected to a company's internal installation, rather than to the public grid. They offer control over peak demand, flexibility during grid congestion, and opportunities to generate revenue through trading or grid services. In this article, you'll learn why this trend is growing so rapidly, what the benefits are, and how a smart EMS makes a difference in efficiency and reliability.
How does battery storage work for businesses (technically and practically)?
Battery storage is playing an increasingly important role in the energy transition. While it was once primarily for grid operators or large solar farms, more and more businesses are now investing in their own battery systems. The technology helps to use energy more intelligently, save costs, and bypass grid congestion. But how does battery storage actually work – both technically and in practice? In this article, we explain what happens inside a business battery, how its control system operates, and what it means for your business operations.
