When is a battery profitable for my business?
Direct answer
A battery becomes profitable for your business when several value streams come together: using more of your own solar power, shaving consumption peaks, responding to price differences and providing services to the grid. A single application is rarely enough. The outcome depends on your consumption profile, your connection and the requirements around safety and grid costs. Measuring and modelling on your own data is therefore the first step.

When is a battery profitable for my business: scattered information versus Energy Intelligence
More and more businesses consider a battery, often after a rejected request for extra grid capacity or with a roof full of solar panels that generates more on sunny afternoons than the building uses. At the same time you hear stories about trading on the energy market and payments from the grid operator. The question is not whether a battery is technically possible, but whether it pays for itself in your situation. That calls for a sober look at where the money has to come from.
- Storing your own solar power gains value now that the Dutch net metering scheme for small consumers ends on 1 January 2027.
- Shaving peaks keeps you within your contracted transport capacity and can postpone a heavier connection.
- Revenues from the imbalance market and congestion services usually run through an aggregator and can be stacked with dynamic prices.
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.
Which value streams can a battery tap into?
A commercial battery earns its keep through a combination of value streams. The first is using more of your own solar power. Now that the Dutch net metering scheme for small consumers ends on 1 January 2027, storing electricity for your own use becomes more attractive than feeding it back. The second is peak shaving: the battery absorbs short peaks so you stay within your contracted transport capacity. The third is responding to price differences. With a dynamic contract you charge at low prices and discharge at high prices. Through the imbalance market of the national grid operator a battery can also help balance the grid, almost always via a specialised aggregator. The fourth is congestion services: in congested areas grid operators pay for flexible capacity. The strongest business cases stack several streams.
- Using your own generation: storing instead of feeding back, especially after net metering ends
- Peak shaving: staying within your contracted transport capacity
- Dynamic prices and the imbalance market: charging low and discharging high, usually via an aggregator
- Congestion services: payment for flexible capacity in congested areas
- Stacking: combining several value streams strengthens the business case
Which factors determine whether it pays off for you?
The same battery delivers a lot at one company and little at another. Your consumption profile is decisive: how high are the peaks, when do they occur and how well does your consumption coincide with your own generation? If you mainly generate when the building uses little, there is more to gain than with a profile that already matches well. The size of your connection also matters, because it limits how much the battery can charge and discharge. A battery also wears with every charging cycle: intensive trading accelerates degradation and shortens its lifespan. On top of that, expect requirements around fire safety, siting and insurance, and grid tariffs and possible connection costs that reduce the return. All these factors together determine the outcome, not the battery itself.
- Consumption profile: the height and timing of peaks and the overlap with your own generation
- Connection: the contracted transport capacity limits charging and discharging
- Degradation: every charging cycle costs lifespan, intensive use wears faster
- Safety and insurance: requirements for siting, fire safety and cover
- Grid costs: grid tariffs and possible connection costs reduce the return
How do you approach the decision?
Start by measuring. Your quarter-hourly data show how high your peaks are, when they occur and how much of your own generation you currently feed back. Then go through the value streams and cross off what does not apply to you: without your own generation the value of self-consumption disappears, and without congestion in your area congestion services drop out. Next, model the remaining streams on your own data, including degradation, grid tariffs and the costs of installation and safety measures. If you consider the imbalance market, ask how the aggregator divides revenues and risks. Finally, explore the subtopics that weigh most in your case, such as the end of net metering, contracted transport capacity, the imbalance market and congestion management. Profitability is not a property of the battery, but of your profile.
- Step 1: request quarter-hourly data and map your own consumption and generation profile
- Step 2: cross off value streams that do not apply to your situation
- Step 3: model the remaining streams on your own data, including degradation and grid costs
- Step 4: assess the agreements with an aggregator before entering the market
- Step 5: explore the subtopics that weigh most in your case
