NLWhat is the imbalance market in the Netherlands?
Supply and demand never match up perfectly
The Dutch electricity grid must be in balance every second. At any given moment, the amount of electricity generated must equal the amount consumed. That sounds simple, but in practice, reality constantly deviates from the plan. The wind blows harder than expected, a solar farm generates less due to cloud cover, or a factory unexpectedly starts up a major process.
We refer to these deviations as ‘imbalance’.
Anyone delving into this subject will soon come across the term ‘imbalance market’. Whilst this term is widely used, it is not technically correct. There is, in fact, no separate market on which imbalance is traded. The term refers to the Dutch balancing system and the financial incentives used within it to keep the electricity grid stable.
For companies with flexible capacity – such as batteries, CHP units or industrial installations – these price incentives are of interest. To understand why, it is first important to understand how imbalance arises.
Why does the electricity grid need to be in balance?
The European electricity grid operates at a frequency of 50 Hz. This frequency can only remain stable if generation and consumption are constantly in balance.
As electricity cannot, for the most part, be stored directly in the grid on a large scale, any deviation must be corrected almost immediately. This is the responsibility of TenneT as the national transmission system operator (TSO).
TenneT continuously monitors the system balance. As soon as generation and consumption become unbalanced, balancing services are deployed to restore the system to balance.

The imbalance price is a financial incentive designed to encourage BRPs to implement their energy programme as accurately as possible.
What do we mean by the imbalance market?
The term ‘imbalance market’ is widely used by battery developers, energy companies and in the media. Formally, however, this market does not exist.
What is usually meant by the ‘imbalance market’ is the combination of:
- TenneT’s balancing system
- the activation of balancing services
- and financial settlement via the imbalance price
The imbalance price is not a trading price like those on the Day-Ahead or Intraday markets. It is a financial incentive designed to encourage Balance Responsible Parties (BRPs) to execute their energy programmes as accurately as possible.
What is imbalance?
Every BRP must submit an energy programme (E-programme) in advance. This sets out how much electricity is expected to be generated, consumed and traded during each settlement period.
In reality, this forecast almost always deviates from the actual figures.
When the actual position deviates from the E-programme, an imbalance arises.
This imbalance is settled financially at the end of the period at the imbalance price. This creates a direct economic incentive to plan as accurately as possible and to actively manage the portfolio.
TenneT monitors the system balance and activates balancing services when necessary.
Who does what?
To understand the balancing system, it is important to distinguish between the different roles.
TenneT (TSO) monitors the system balance and activates balancing services when necessary.
A Balance Responsible Party (BRP) or programme manager is responsible for submitting the E-programme and bears the financial risk of imbalance.
A Balancing Service Provider (BSP) provides flexibility to TenneT. This can be achieved, for example, using batteries, CHP units or other flexible installations that can quickly adjust their output.
Why is imbalance of interest to businesses?
The imbalance price is primarily intended as a financial incentive for BRPs. At the same time, this pricing mechanism ensures that flexibility is given economic value.
The imbalance price is primarily intended as a financial incentive for BRPs to execute their energy programme as accurately as possible. With a supply contract that is exposed to the imbalance price (a so-called trading contract), opportunities also arise to actively respond to these price incentives.
This can be done in two ways: by actively adjusting (nominating) the E-programme or by flexibly adjusting generation or consumption capacity. In this way, flexibility is not only used to support the electricity system, but can also create economic value.
Why is this more complicated than it seems?
On paper, it sounds simple: a high imbalance price means responding.
In practice, many more factors come into play.
The expected imbalance price changes constantly. Batteries have technical limitations such as State of Charge, charging and discharging capacity, and availability. Furthermore, the same battery can create value in multiple ways.
The question is therefore not just whether a battery should respond, but above all when and how the highest economic value can be realised.
This requires real-time market information, forecasts and automatic optimisation.
Imbalance is primarily intended as a financial incentive for BRPs. At the same time, this pricing mechanism ensures that flexibility is given economic value.
Imbalance is just one way of deriving value from flexibility
Although much attention is focused on imbalance, this is just one of the ways in which flexible capacity can generate revenue.
The same installation can also be used to provide balancing services via a BSP such as Enova or to create value in other energy markets.
The optimal strategy is constantly changing. Sometimes it is attractive to respond to the imbalance price, whilst at other times a different approach yields greater returns.
The challenge is therefore not to always respond to a single price signal, but to continuously determine the most economically viable use of the available flexibility.
How does Enova help?
Deriving value from flexibility starts with the right strategy. Not just when the imbalance price is high, but on an ongoing basis, tailored to the company’s operations.
Enova helps companies and organisations by linking the energy market with their day-to-day operations. Together with the customer and the BRP, we develop trading strategies that align with the available flexibility, energy requirements and business objectives. Our optimisation software supports the nomination process, whilst a dedicated Energy Manager monitors, refines and, where necessary, adjusts the strategy.
As an accredited BSP, Enova also unlocks additional value through strategic approaches. Depending on the available flexibility and market conditions, assets can be deployed for balancing services such as FCR, aFRR and mFRR. The optimal deployment varies from moment to moment. Sometimes the highest value lies in the imbalance price, sometimes in balancing services, or a combination of different markets.
That is why Enova does not focus on a single battery or installation, but on the entire energy operation. Production, consumption, generation, storage and other flexible assets are optimised as a whole to reduce energy costs, increase revenue and minimise operational risks.
Enova’s customers have real-time insight into market developments, performance, trading results and the value generated by their flexibility. This enables them to maintain control over their energy operations and the return on their investments.
