Use cases

Typical projects of our installation partners

Three case studies from the field and four scenarios you encounter every week as an installer, and how you win them with Voltmasters EMS.

Three case studies from the field

Open BESS container with battery racks at the Cras site in Ostend, with the CRAS building in the background

Case study 01 · Cras Ostend · Power Boost Reserve

300 kW of charging power on a 250 kW connection

Two Alpitronic HYC150 fast chargers demand 300 kW combined, while the grid connection delivers only 250 kW. In a competitive charging market, curtailment is not an option: a driver who sees 75 kW instead of the promised 150 kW drives on to the next charger, and doesn't come back.

A 250 kW / 500 kWh battery, intelligently steered by the Voltmasters EMS, automatically covers the shortfall. On top of that, the battery delivers balancing services, always respecting the available Power Boost Reserve. If the battery runs low, the EMS automatically switches to curtailment so the installation stays safe and stable.

Result: full charging power, no loss of charging time, charging experience or customers, without an expensive, lengthy grid reinforcement.

Case study 02 · EV charging infrastructure · Negative prices

Trucks that get paid to charge

A transport company in West Flanders charges a fleet of eleven electric trucks on a limited grid connection, with battery storage and solar panels on site. At moments with negative energy prices, the EMS flips the logic:

  1. The batteries sell energy first, freeing up room for cheap or negative power.
  2. At negative prices, the whole site charges from the grid at full capacity.
  3. The solar panels are temporarily limited to take maximum advantage of the grid.
  4. The EMS steers all assets as one efficient ecosystem.

Lowest point 13:45  −€200.83/MWh

Result: the trucks don't just get charged, they even get paid for it.

Truck B · ready by 12:00

Priority 2

Truck C · no deadline

Flexible, cheapest hours

Case study 03 · Truck fleet · Battery Schedule

Every truck charged on time, every time

Multiple trucks charge at the same time, with very different departure times. Without smart steering, every vehicle gets the same power: priority trucks come up short on energy, while non-urgent vehicles load the grid during expensive peak hours.

The Battery Schedule in the Voltmasters EMS calculates the optimal charging plan per vehicle ahead of time, based on departure time, available grid capacity and dynamic energy prices. The truck with the earliest departure gets immediate priority, the second one is ready exactly on time and the flexible vehicle charges in the cheapest hours. If anything changes, the system recalculates the schedule instantly.

Priority per vehicle Deadline-driven charging Real-time recalculation Cost optimisation

Result: every charging deadline met, at the lowest possible energy cost.

Four scenarios you encounter every week

SME · Battery & imbalance market

The battery that earns at night too

An SME installs a 233 kWh battery alongside its dynamic energy contract. The EMS arbitrages daily on day-ahead prices: charging on the cheap, sunny afternoon, discharging during the expensive evening peak. On top of that, it makes the battery available on the imbalance market through a trading partner. Dispatch signals take priority but stay within the grid contract.

Result: two revenue streams from one battery, even outside opening hours.

Industry · Capacity tariff

The quarter-hour peak under control

A manufacturer watches its capacity tariff rise year after year. Through the A1 port of the Fluvius meter, the EMS tracks the quarter-hour values in real time, exactly the same measurement as the invoice, and shaves the peaks with the battery, without touching production. Planned large loads are entered in advance so the battery pre-charges.

Result: a lower peak bill, no extra sub-meters, invoices that match the measurement.

Logistics · EV charging plaza

A charging plaza without grid reinforcement

A logistics site wants to charge a fleet of electric vehicles on a connection that was never designed for it. Load balancing distributes the available power dynamically across the charge points, the battery assists at peak moments and vehicles always get priority. When thresholds are exceeded, low-priority loads are shed automatically.

Result: the entire fleet charged within the existing grid connection.

C&I · Telecontrol > 100 kVA

Telecontrol without the headaches

For a storage system above 100 kVA, the grid operator requires telecontrol. The EMS processes the Fluvius RTU signals (IEC 60870-5-104 over Netflex) as a constraint in the optimisation and ramps down in a controlled way, with a hardware emergency stop via Moxa IO modules. Voltmasters validates against real measurements beforehand and supports the formal certification with real-time diagnostics.

Result: a compliant installation, certification often completed in a single session.
