We calculate this based on your consumption peaks, consumption profile and future charging demand (such as charging infrastructure). During the energy scan we determine how many kWh and kW power are optimal.

The investment varies greatly per project, from tens of thousands of euros for a compact rack system to several hundred thousand euros for a container solution on MWh scale. Determining factors are capacity (kWh), peak power (kW), technology (LFP/NMC), integration with PV and charging infrastructure, and the grid connection on site. During the on-site energy scan we calculate the optimal sizing and expected payback period for your situation.

Peak shaving is smoothing out consumption peaks: the battery provides power when your consumption suddenly increases, so your grid consumption remains limited and you pay less for peak power.

Yes. In many cases battery storage is faster and cheaper than grid reinforcement. The battery buffers energy locally so your connection stays within existing limits.

Yes, provided certified LFP/NMC modules, fireproof housing, correct cooling and monitoring are used. Powerland only works with proven systems according to European safety standards.

Yes, if the installation is provided with UPS functionality or back-up mode. This keeps critical infrastructure active during a power outage.

A battery becomes interesting for businesses with a regular peak consumption above 15-30 kW or an annual consumption above approximately 50,000-80,000 kWh. The higher the peaks, the faster the saving. For charging plazas, compressors, cooling, forklifts or electric fleets, battery storage is almost always profitable. During the energy scan we measure your peak profile and calculate which storage capacity (kWh) and power (kW) are optimal for your site.

No. In most cases a battery actually avoids grid reinforcement. An industrial battery buffers energy locally and provides power during peak moments, so your connection stays within existing limits. Only when your continuous consumption structurally becomes higher than the current grid capacity may reinforcement remain necessary. During the energy scan we analyze your peak profiles and determine whether battery storage can completely avoid or postpone grid reinforcement.

Yes, a battery can be profitable even without solar panels, especially for businesses with high peak consumption, variable production moments or electric charging infrastructure. In that case the battery is used for peak shaving: it provides power during peaks, so your grid consumption stays within limits and you pay fewer peak penalties. The ROI then mainly depends on your peak profile and energy tariffs, not on PV yield.

A battery container is only the physical housing in which batteries and components are placed.
A BESS (Battery Energy Storage System) is the complete energy system: battery modules, inverters, BMS, EMS, cooling, safety and the container or cabinet in which everything is housed.

In other words:

• Battery container = the box / housing
• BESS = the fully working system

This depends on both your connection capacity (technical maximum power) and your access capacity (contractual power). In Belgium the low voltage limit is around 160A (≈110 kW).
If your business structurally exceeds this limit, you must request an upgrade, but this may be refused by the grid operator when there is grid congestion.
If the upgrade is approved, Fluvius will provide a new cable up to your property, but all costs are for the applicant, including excavation works and the placement of a medium voltage cabin with transformer and protection.
With battery storage you can often stay below 160A, provided the battery has sufficient time to recharge between peaks. This can sometimes avoid an expensive grid reinforcement or medium voltage cabin.

Yes, businesses can generate income through the imbalance market, but only when the battery is linked to a recognized energy service provider (aggregator) that offers balancing services. The battery is then used to stabilize the grid by automatically charging or discharging when there is a shortage or surplus of energy. Profit depends on market volatility, battery capacity, response time and contract type. This requires a suitable EMS and specific certification.

An industrial battery lasts on average 10 to 15 years, depending on the cell type (LFP or NMC), temperature, number of charge cycles and charging strategy. LFP batteries typically achieve 6,000-10,000 cycles and retain 70-80% capacity after ten years. A good EMS extends lifespan by charging smartly, limiting peak load and avoiding deep discharge.

Grid reinforcement is needed when your continuous consumption is structurally higher than your current connection capacity. You calculate this by analyzing your quarter-hour values (15-min interval) or peak profiles. If your consumption consistently exceeds your contractual limit, this indicates a need for reinforcement. For irregular peaks, battery storage is usually a cheaper alternative. Powerland performs this analysis during the energy scan, including simulation of peak trends and required kWh buffering.

Your connection capacity is the maximum power your electrical connection can technically handle. This is determined by the grid operator, the cable, the fuses and (for medium voltage) the transformer.
Your contractual capacity (also access capacity) is the power you agree with the grid operator and for which you pay. This may be lower than what is technically possible.
If your consumption often exceeds the contractual capacity, you pay more. If it structurally exceeds the connection capacity, an upgrade or another solution (e.g. battery storage) is needed.

Grid congestion means that the electricity grid in a certain region is overloaded. There is insufficient capacity to supply additional power (consumption congestion) or to send surplus energy back to the grid (injection congestion). As a result, businesses cannot request higher capacities, expand or fully inject their production.
With battery storage and smart control (EMS) you can locally absorb grid congestion, provided the battery has sufficient time to charge between peak moments. If the base load is structurally too high, grid reinforcement sometimes remains necessary.

In Belgium, your energy cost is partly determined by the highest quarter-hour power of the month. This peak power may be higher than your contractual capacity. When this happens, you pay peak penalties.

Therefore every business should evaluate what is financially most interesting:

• Increase contractual capacity
• Smooth out peak consumption with battery storage
• Keep paying peak penalties (can sometimes be the cheapest option for rare peak moments and limited exceedances)

At Powerland we make a simulation for you of what is most interesting for your business.
