What is the reference meter / power measurement?

> A reference meter in a battery storage system (BESS) serves the legally secure recording of the amount of energy injected or withdrawn in accordance with the MessEG. The power measurement documents the instantaneous active power in kW, which is critical for the design and monitoring of the battery cells. This data forms the basis for calculating actual profitability (Rentabilité) by reconciling feed-in remuneration and self-consumption.

No own register — honestly

For this component, no own register is connected; therefore, no example value is provided here. Where the system measures, the value is read as read-only and calculated internally. It is visible via connected components.

What the AI reads in this component

What the AI reads
  • Reference meter: Legally secure billing of the quantity of energy to meet legal measurement requirements.
  • Power measurement: Monitoring of discharge currents to minimise thermal stress in the BESS.
  • Cycle tracking: Indicator of cell degradation and calculation of remaining useful life.
  • Grid stabilisation: Proof of power supply to optimise the business case.
Scenario

Monitored: continuous

The scenario: > Monitored: continuous · Grid point & PCS The scenario: an unmitigated peak defines the annual maximum value, resulting in a higher power price for twelve months. The AI: detects the rising edge early and discharges against it — the peak does not occur. It identifies the trend before the limit is reached.

Why it is important

Precise measurement data enable the exact calculation of ROI by reconciling actual throughput and system losses. The integration of reference meters ensures compliance with the MessEG and prevents billing errors. Accurate power measurement protects the hardware from overloading and maximises the lifespan of the BESS. avoided peak (kW) · power price (€/kW·a) → — €/year Calculation path: avoided peak × power price
