How do I earn money with flexibility on the imbalance market?
Direct answer
You can earn money with flexibility on the imbalance market by deploying controllable power at moments when TenneT sees the Dutch grid drift out of balance. This can be done passively, by shifting consumption or generation in response to the imbalance price, or actively, by supplying reserves to TenneT through a balancing service provider. Returns vary strongly per quarter hour and require professional control.

How do I earn money with flexibility on the imbalance market: scattered information versus Energy Intelligence
The Dutch electricity grid must stay in balance every second. The growth of solar and wind creates unexpected shortages and surpluses more and more often. Businesses with controllable power, such as a battery, combined heat and power, cooling, an electric boiler or charging infrastructure, can respond to this. Picture a cold store running its compressors a quarter hour earlier or later. That flexibility has value, but only when metering, control and contracts are properly arranged.
- TenneT settles imbalance per quarter hour: the imbalance price can spike high, but can also turn negative.
- Responding passively to the imbalance price runs through your supplier or aggregator, active bidding on reserves such as FCR and aFRR runs through a balancing service provider (BSP).
- Without fast metering, automated control and clear agreements on balance responsibility, wrong steering costs money instead of earning it.
Insight
Traditional approach
Information is scattered across portals, documents, invoices or separate spreadsheets.
Modern approach
Data, context and interpretation are brought together into a clear decision picture.
Decision-making
Traditional approach
Choices are made based on averages, assumptions or occasional analyses.
Modern approach
Scenarios, KPIs and current measurement data make the trade-off more concrete and repeatable.
Follow-up
Traditional approach
Actions often stay non-committal or disappear into separate reports.
Modern approach
Follow-up actions, monitoring and reporting are linked to the same energy data.
How does the imbalance market work?
TenneT, the national transmission system operator, continuously guards the balance between electricity supply and demand. Every connection falls under a balance responsible party (BRP), previously known as the programme responsible party. If actual offtake or feed-in deviates from what was declared in advance, TenneT settles the difference per quarter hour at the imbalance price. That price reflects what TenneT pays to restore the grid and therefore fluctuates strongly. During a shortage the price rises, during a surplus it can turn negative. A business that shifts consumption or adjusts generation at the right moment supports the system and can receive the imbalance price. Steering the wrong way means paying that same price to TenneT.
- TenneT settles imbalance per quarter hour, the imbalance settlement period
- The imbalance price can swing from negative to very high within a single day
- TenneT publishes imbalance prices almost in real time, so market parties can respond
- Moving with the system earns money, moving against it costs money
Responding passively or bidding actively: which route fits your business?
There are two routes. With passive balancing you steer your own consumption or generation in line with the live imbalance price that TenneT publishes. You deliver nothing to TenneT directly, but you improve the position of your balance responsible party. This is usually arranged through your energy supplier or an aggregator that controls your installations automatically. With active bidding you make capacity available as a reserve through a balancing service provider (BSP). Think of products such as FCR for fast frequency support and aFRR for regulating power. These require prequalification and compliance with technical requirements. For the BSP role TenneT applies a minimum of one megawatt, and an aggregator may bundle smaller installations into a pool. The right route depends on your capacity, your response speed and the operational commitment you can carry.
- Passive: moving with the imbalance price through your supplier or aggregator, without a delivery obligation to TenneT
- Active: bidding on FCR, aFRR or mFRR through a BSP, with prequalification and obligations
- Smaller installations participate through a bundled pool run by an aggregator
- Batteries, CHP, cooling, electric boilers and charging infrastructure are common sources of controllable power
What do you need and which risks apply?
Earning from imbalance starts with controllable power that responds quickly and reliably. You also need metering per quarter hour or faster, automatic control through an energy management system, and a contract that defines who steers and who carries the imbalance risk. Keep expectations honest. Imbalance prices are highly volatile: quarter hours with high prices alternate with long quiet periods. Steering wrongly or too late costs money instead of earning it. Anyone offering contracted reserves must deliver when TenneT calls, even when that is operationally inconvenient. Batteries degrade faster under intensive charging and discharging. Have the value of your flexibility calculated in advance, so you know which route fits. Separate explainer pages cover related subtopics such as imbalance prices, aFRR, batteries and aggregators.
