Flex-e: Subsidy for flexible electricity consumption

The power grid is at capacity—you’ve probably already noticed. You might not be able to upgrade your connection. Meanwhile, your business just keeps growing… or at least it should.

Through the Flex-e subsidy program, the government is encouraging companies to use their existing connections more efficiently—not by requesting additional capacity, but by creating flexibility within the existing infrastructure.

  • Get more out of your existing connection without relying on network upgrades
  • Taking immediate steps toward growth and electrification, despite grid congestion
  • More effective management of energy consumption and costs, with support from grants

Why this grant exists

Network congestion is becoming a problem in more and more places across the Netherlands. Specifically, this means:

  1. No or limited expansion of your connection
  2. Long wait times for increased benefits
  3. Restrictions on the sale of surplus solar energy
  4. Uncertainty in your energy supply

For many companies, this feels like a roadblock—to growth, to electrification, and to plans that were already in place.

The Flex-e program aims to reverse that trend. Instead of waiting for the grid, it encourages smarter self-management.

What does the Flex-e subsidy entail?

The program is designed for companies that are making their electricity consumption more flexible. The focus is on measures that help reduce peaks, use energy more efficiently, or temporarily store it. These include energy storage, demand response, or combinations of these.

In short:

  • Grant of up to 40% for flexibility measures
  • Grant amount between €25,000 and €300,000
  • Designed for businesses with a high-volume connection (GV)
  • Only in areas with grid congestion

Application period:
May 6, 2026 – October 15, 2026
Total budget:
€16.1 million

Who might be interested in this program?

The Flex-e program is designed for companies that are reaching the limits of their current connection but still want to move forward. Not by waiting for an upgrade, but by making smarter use of what they already have. In practice, we see this happening frequently with companies that have higher energy demands and concrete growth plans.

FLEXIBILITY WITHOUT A COMPLEX PROCESS

“Many business owners think that flexibility has to be something big and complicated right off the bat. In practice, it’s often not as bad as it seems. If you approach it the right way, you can make progress relatively quickly within your existing plan.”

Orlando Founder of Boltainer

Industry and Manufacturing

Companies where energy is directly linked to production. If you can’t scale up due to grid constraints, you’ll see it immediately in your output.

Logistics and Transportation

Distribution centers and logistics hubs with electrification plans or charging infrastructure. In these locations, energy demand often rises rapidly, while the power supply lags behind.

Agricultural sector

Businesses with solar panels, peak demand, and seasonal fluctuations. That’s exactly where there’s significant potential for smarter management.

Companies with electrification or charging plans

Think of charging stations, vehicle fleets, or properties with growing electricity demand. The connection is often the limiting factor, not the ambition.

The difference that is often overlooked

There is one practical distinction in the regulations that is quite significant. And that is precisely where many companies fall short—not because of the technology itself, but because of the process involved.

Less than 100 kW

  • A relatively straightforward process
  • No complex congestion management contract is required
  • Faster to implement
  • Less dependent on external parties

Over 100 kW

  1. More complex (studies, contracts, coordination)
  2. Longer turnaround time
  3. More uncertainties

You go through this process

1

Submit an application

You must submit the application along with the required documents and justification for the measure.

2

Assessment (8–16 weeks)

The review process takes 8–16 weeks. If approved, you will receive 90% of the grant as an advance payment.

3

Implementation

You must implement the measure within two years of its approval.

4

Determination & Payment

After completion, you must submit a final report. Once it has been reviewed, you will receive the remaining 10%.

What you need to submit with your application

The application itself is fairly straightforward, though it may seem a bit technical at first. It sounds like a lot of steps, but in practice it’s easy to navigate, provided the plan is sound.

You will need the following, among other things:

  • Understanding your current electricity demand
  • An explanation of how to build flexibility and what the effect is
  • For larger projects (>100 kW): technical design
  • De minimis declaration

Farmer Dairy farmer

"Our solar panels are really paying off now! With Boltainer batteries and BBT software, we use our own electricity whenever it suits us and save a lot on feed-in tariffs."

Fleet & Equipment Manager Construction company

"We need far fewer diesel generators on the construction site. Combined with battery storage, we now always have a reliable and sustainable power supply, no matter where we're working."

Facilities Manager Industrial sector

"Thanks to Boltainer, we've reduced our energy costs by over 30% and are no longer subject to grid restrictions. Our production is running more efficiently than ever!"

Battery Storage in Practice

SOLAR OPTIMIZATION AT AN AGRICULTURAL SOLAR PARK

Overijssel
With the BOLT-40 and forecasting software, an agricultural solar farm no longer feeds electricity back into the grid at low rates, but instead stores it and sells it at the best possible time.

Results

  • Energy stored and managed locally
  • Earning on the EPEX and imbalance markets

Jumbo Mieremet launches 400 kW fast charger with battery storage

Jumbo Mieremet in The Hague became the first supermarket in the region to install a 400 kW DC fast-charging station with 430 kWh of battery storage. Thanks to the smart use of storage, two cars can charge simultaneously without placing an additional load on the power grid.

Results

  • Fast charging without overloading the grid
  • Charging two cars at the same time

Frequently Asked Questions About the Flex-e Grant

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

Am I eligible for the Flex-e subsidy?

That depends on your connection, location (network congestion area), and type of business. In practice, this can be quickly verified with a quick check.

Exactly how much is the grant?

You can receive a subsidy of up to 40% of the costs of flexibility measures, subject to a minimum and maximum amount.

How long does the application process take?

The review usually takes 8 to 16 weeks. After that, you can begin implementation.

Is the process difficult to navigate?

That depends on the situation. Smaller measures are often relatively simple, while larger projects require more coordination.

Do I have to take care of everything myself?

No, you’re usually guided through the process, from application to completion, so that everything stays organized.

Would you like to know if this is of interest to your company?

Not every situation is the same. Sometimes it makes perfect sense to get started on this. Sometimes it doesn't—or not yet.
