Is network congestion holding your business back? Take back control.

Network congestion... What can you actually do about it?

More and more companies are running into bottlenecks due to limited grid capacity, and projects related to growth, electrification, and sustainability are being postponed. Discover how you can create capacity within your existing grid connection without waiting for grid upgrades or making large capital investments.

In practice, waiting for network upgrades means:

❌ Delayed expansion of production or charging infrastructure
❌ Limited feed-in of solar power
❌ Peak loads that disrupt your operations
❌ Strategic uncertainty in investment decisions

That is why we worked with experts to write this guide:

  • What network congestion really means for your business operations

What is network congestion, and why is it a problem?

Grid congestion occurs when the power grid can no longer meet the demand for electricity. This is because more and more businesses and households are switching to renewable energy, electric vehicles, and the electrification of processes. As a result, the grid’s capacity becomes overwhelmed, and energy cannot always be drawn from or fed back into the grid when needed.

Grid congestion hinders growth, increases operational costs, and makes businesses dependent on an unstable grid. A smart battery solution helps optimize energy usage and circumvent grid constraints.

"Companies are increasingly losing control over their energy and efficiency"

“Grid congestion and rising energy costs are forcing companies to adopt a different approach. Without control over your energy supply, it’s becoming increasingly difficult to operate efficiently. Using energy wisely is no longer a choice, but a necessity.”

Orlando Co-founder of Boltainer

Limited network capacity is holding back growth

The power grid was not designed to handle large-scale local generation and consumption. Due to limited grid capacity, businesses are unable to obtain additional connections, which brings expansion or electrification to a standstill. This hinders growth and forces businesses to seek alternative solutions to ensure their energy security.

Overload caused by feed-in costs money

On sunny and windy days, more energy is sometimes generated than the grid can handle. This means that companies cannot feed their surplus solar energy back into the grid or must sell it at low rates. As a result, investments in renewable energy become less profitable and opportunities for savings are lost.

Growing demand for energy

Demand for electricity continues to rise due to the electrification of industry and transportation. Because of limited grid capacity, peak periods are becoming increasingly expensive, resulting in higher fixed charges and additional grid surcharges. Inefficient energy management thus leads to unnecessarily high costs and dependence on expensive grid connections.

Negative electricity prices? Grid congestion makes it worse

In 2025, a record number of hours with negative electricity prices was once again reached. Due to grid congestion and a surplus of solar energy, prices are increasingly dropping below zero—precisely when you’re feeding power back into the grid.

Result: lower returns—or even having to pay for your own electricity. With a smart battery, you can temporarily store energy and use it when it’s actually profitable. This way, you stay in control, even during grid congestion.

Maximize energy savings and reduce costs

More control

Always ensure you have enough power by temporarily drawing extra power from your battery when energy consumption peaks.

This gives you the following:

  • Local additional power for charging stations and high-demand users, among others
  • Become virtually independent of the grid
  • Significant savings on peak power costs

Additional revenue

Earn extra income and mitigate the impact of grid congestion by automatically trading surplus energy on trading platforms such as EPEX and the imbalance market.

This gives you the following:

  • Maximizing the efficiency of every kWh
  • Sell surplus inventory automatically at opportune times
  • Up to 20% higher annual returns through smart energy trading

Independence

Switch to greater efficiency and lower costs. Make the most of your energy with a smart battery, without being subject to grid restrictions.

This gives you the following:

  • Avoid high costs associated with a more robust grid connection

Use clean energy more efficiently

Store the solar or wind energy you generate yourself and use it when you need it. Reduce your reliance on the grid and increase your self-consumption.

More power on-site

Generate additional local power for charging stations, heavy machinery, or other high-power consumers without having to apply for a more expensive grid connection.

Maximize your solar energy with smart storage

Store excess solar energy and use it when the sun isn't shining. This way, you can lower your energy bill and increase your self-consumption without wasting energy.

Maximize your revenue

Grid congestion can force companies to reduce production or even shut down, which has a direct impact on revenue. With a smart battery, you can ensure a stable power supply, even when the grid cannot provide enough power. This keeps machines running, maintains process efficiency, and prevents revenue loss due to unexpected power restrictions. This way, you not only ensure the continuity of your business, but also make the most of every productive minute.

Answers to frequently asked questions

Can't find your question here? Please contact us.

How does grid congestion in the region affect my business?

Grid congestion means that the power grid in your region is overloaded, which may prevent you from purchasing or feeding back additional electricity. This can limit growth, increase peak-load charges, and prevent you from making the most of your renewable energy solutions.

How can a battery help with grid congestion?

A smart battery stores energy when the grid isn't under load and supplies it when you need it. This allows you to reduce peak demand, avoid grid overload, and store energy instead of feeding it back into the grid at low rates.

Can I still install solar panels if there is grid congestion?

Yes, but you may not be able to feed all the energy you generate back into the grid. With a battery storage system, you can store your solar energy and use it later, so you can still benefit from your investment without relying on the grid.

What happens after I submit the form?

After you fill out the form, we’ll request some additional information, and you’ll receive a personalized report. This report provides insight into your current energy consumption, highlights potential savings, and offers concrete recommendations for optimizing your energy management with Boltainer’s smart battery solutions.

What information will you need for the calculation?

To provide an accurate calculation, we need the following information:

  • Type of energy contract: Fixed or dynamic.
  • Number of ampere connections: This can range from 3x25A to 3x630A.
  • Annual energy fed back to the grid (kWh): How much energy do you feed back to the grid each year?
  • Annual consumption (kWh): What is your total annual energy consumption?

For connections of 80A or higher, we also need:

  • Contracted power capacity (kW): The maximum amount of power you are allowed to draw from the grid.
  • Maximum feed-in (kW): The maximum amount of power you can feed back into the grid.

If you're not sure how to fill out this information, just leave your personal details and we'll get in touch.

How long does it take to install the battery?

The battery is typically installed within 6 to 8 weeks after the quote is finalized and the project plan is approved. This includes delivery, installation, and configuration, so you can start enjoying your new energy solution right away. If customization is required, we will let you know the exact timeline.

How can the scan help me save energy?

The scan provides a comprehensive overview of your current energy consumption and how you can manage it more efficiently. By gaining insight into peak consumption, net metering, and storage optimization, you’ll receive practical advice to help you reduce costs and make your energy management future-proof.

How accurate are the estimated savings and returns?

The results are based on current data and market prices, combined with your specific usage profile. While this provides a good estimate, actual savings may vary due to factors such as grid congestion, market fluctuations, and weather conditions.
