Why a battery for your business?
Lower capacity tariff and peak demand
Your grid bill is driven by your highest quarter-hourly peak. A battery shaves those peaks and structurally reduces capacity charges.
More solar self-consumption
Without storage, midday output goes to the grid at low or negative prices. A battery shifts that energy to evening and morning hours, lifting self-consumption to 70–90%.
Flexibility revenue
Through an aggregator your battery delivers grid services to Elia (aFRR, imbalance), shortening the payback period.
Protection against price volatility
Dynamic tariffs reward load shifting. The energy management system charges cheap and discharges during expensive hours, automatically.
CleverNett carries the investment
A commercial battery requires serious CAPEX. With CleverNett you don't carry it: we invest, build and operate the installation on your site. You only pay for the energy and savings actually delivered.
Your balance sheet stays free for your core business, with no technical risk and no maintenance worries. The system stays under our management and is monitored 24/7.
- No investment, no residual value risk
- Design, construction, permitting and grid connection included
- Maintenance, monitoring and warranties on us
- Combines with rooftop solar or a corporate PPA
What does a commercial battery cost?
Price depends on power (kW), capacity (kWh), grid connection and the services you stack. These are 2026 Belgian benchmarks — in a CleverNett partnership you don't carry this investment.
| Segment | Typical size | Indicative CAPEX |
|---|---|---|
| SME | 100–250 kWh | €40,000 – €100,000 |
| Mid-sized industry | 250 kWh – 1 MWh | €100,000 – €350,000 |
| Large industry / co-located | 1 MWh and up | €250 – €400 per kWh |
Benchmarks include inverters, EMS and installation, excluding grid reinforcement. The business case is built on your last 12 months of quarter-hourly data.
Battery storage for SMEs
Storage pays off beyond heavy industry. For SMEs connected from roughly 250 kVA with a pronounced peak profile — cooling, EV chargers, production lines — peak shaving often returns within a few years.
We always start with a free battery scan: we analyse your quarter-hourly data, size the battery and show the expected savings before anything is decided.

Frequently asked questions
What does a commercial battery cost in Belgium?
Expect roughly €250 to €400 per kWh for larger industrial systems and €40,000 to €100,000 for a 100–250 kWh SME battery. In a CleverNett partnership, CleverNett carries the investment.
How fast does a commercial battery pay back?
Typically four to eight years, depending on peak profile, self-consumption and flexibility revenue.
Is battery storage worthwhile for an SME?
Yes, from roughly 250 kVA of connection capacity and a pronounced peak profile.
Do we need to invest ourselves?
No. CleverNett finances, builds and operates the installation.
