Maximise the value of your energy assets through intelligent market integration

The platform connects directly with energy suppliers and trading partners, enabling dynamic control of batteries, solar, charging infrastructure and steerable consumers based on real-time market signals.

Arbitrage on dynamic prices

The EMS checks day-ahead market prices (EPEX) and automatically schedules the battery per quarter-hour: charging in cheap slots (PV surplus or cheap grid), discharging in expensive slots. The battery shifts energy from the cheap, sunny afternoon to the expensive evening peak, and your customer avoids expensive grid purchases.

  • Plan is updated every 15 minutes based on prices, PV forecast and consumption
  • Only cycles when the price spread justifies the round-trip losses (configurable, typically €20/MWh)
  • Solar curtailment at negative injection prices

Imbalance market via trading partners

Automated participation in flexibility markets: the trading partner sends dispatch signals that give the battery precise charge and discharge commands. Partner signals take priority over the standard algorithms but always stay within the project limits and safety margins of the grid contract.

  • Secure connection via MQTT (certificate-based) or REST API (API key)
  • Live imbalance prices and per-device activation status in the Pro dashboard
  • Full alignment with local market rules and supplier communication protocols

Buy low, sell high, automatically

One day on the day-ahead market. The EMS charges the battery in the cheap midday dip and discharges it again during the expensive evening peak.

Built for Elia's imbalance and balancing markets

The EMS takes a decision every second for every device, taking each device's response speed into account. With a reaction time of 1 to 3 seconds you capture real-time price spreads and reserve activations, while slower systems are still computing.
