Energy storageFixed battery storage (BESS)

battery storage that pays for its place

From a 107 kWh cabinet in a car park to 5 MWh containers combined into multi-MWh plants. Storage cuts the peak that sets your grid fees, stores solar, keeps the site running, lets chargers draw more than the connection and trades the hours in between. The EMS decides which matters most.

WattsFuture battery storage: commercial cabinets and 20 ft containers.

The range

Cabinets and containers, 107 kWh to 5 MWh

Tier-1 LiFePO4 cells, from WattsFuture in the Netherlands. Several units combine into one plant; the largest containers are paired with a separate power-conversion container.

What storage does

Six ways a battery earns

  • Peak shaving

    Caps the site's peak so the power-based part of the grid fees stays low.

  • Solar self-consumption

    Stores midday solar for the evening and the night instead of exporting it cheaply.

  • Charging boost

    Lets DC chargers draw more than the grid connection; the limit is never crossed.

  • Backup

    Keeps critical loads running through a grid outage, with seamless switch-over where required.

  • Trading

    Charges in cheap hours and discharges in expensive ones, on day-ahead and intraday prices.

  • Balancing markets

    Earns from FCR and aFRR in the hours the site does not need the battery.

Peak price

The peak is covered by the battery

At a peak price of about €170/MWh, solar and the battery cover a 1.6 MW truck session. Grid import drops to about 100 kW.

  1. Peak price: The peak is covered by the battery. At a peak price of about €170/MWh, solar and the battery cover a 1.6 MW truck session. Grid import drops to about 100 kW.
  2. Grid support: Grid support in seconds. The grid frequency dips to 49.87 Hz and the battery discharges over 1 MW within seconds. The EMS can offer this response on balancing markets.
  3. Solar surplus: Solar used on site, by priority. 1.6 MW of solar: the building first, then 1 MW to the DC chargers, the rest to AC charging with VOOL load management. Nothing is wasted.

Energy management

What the EMS knows, and what it does with it

Inputs

  • Day-ahead prices and grid tariffs
  • Solar and consumption forecasts
  • Connection-point limits
  • Live metering (Modbus TCP, e.g. Socomec meters)

Outcomes

  • Peak shaving, lower power-based fees
  • Maximum solar self-consumption
  • More charging power on the same connection
  • Revenue from trading, FCR and aFRR where allowed

Tooling

  • WattsRouter edge controller on site
  • WattsMonitor cloud dashboards and alerts
  • Full analytics before you invest
  • Controller + installation + a small monthly fee

Storage questions

“Who sells and installs battery storage for companies in Luxembourg?”

AMP X VOLT supplies, installs and operates WattsFuture LiFePO4 battery storage: cabinets of 107, 215, 218 and 241 kWh and 20 ft containers from 1.3 to 5 MWh, combined into multi-MWh plants, with an EMS that manages grid limits, prices, solar and EV chargers. Engineering includes the grid connection, protection, earthing and the grid-code file.

“Can a battery let EV chargers use more power than the grid connection?”

Yes. The battery charges when the site has spare capacity or cheap energy and discharges into the chargers at the peak, so the chargers can draw more than the connection while the connection limit is never crossed.

“Can storage be financed without capex?”

Yes, for projects from about €1 million per client: with AMP X VOLT's partner investment fund for energy infrastructure, the fund finances and owns the system, AMP X VOLT builds and operates it, and the client pays one monthly fee (capacity as a service).
