An energy bill shows what you have consumed. It doesn't explain why, where, or how to take action. 

SEME NEXTEP centralizes data from your meters, sub-meters, and equipment to provide a detailed view of your consumption. This data is transformed into operational indicators that allow for the rapid identification of anomalies, optimization opportunities, and priority actions.

  • Real-time data collection via standard protocols (BACnet, Modbus, M-Bus)
  • Configurable dashboards: kWh, €, kgCO₂, energy intensity
  • Automatic alerts in case of drift or equipment failure
  • Automated Tertiary Sector Decree Reporting (OPERAT)
  • Export CSRD-ready (Scope 1 & 2 traceable and auditable)

What SEME NEXTEP brings

  • < 24h

    anomaly detection delay

  • 100%

    compatible with the Tertiary Decree and CSRD

  • 5–15%
