Power & Peaks

The Power & Peaks page shows how your load is distributed over the selected period. The focus is on three KPIs, the Load Duration Curve, and your highest peaks.

Note: Power & Peaks is part of the advanced analysis, which is included from the Plus plan upwards. It also requires at least hourly values. You can see Base load and Peak as reference lines in Consumption & Load as well. This page puts those values in context and shows the full distribution.

Base load, peak load, and hours above threshold

At the top you see three KPIs:

  • Base Load: The minimum continuous power of your connection. It is calculated as the 5th percentile (P5) of load values, meaning the power level exceeded during 95% of the time. A high base load points to devices running around the clock.
  • Peak Load: The highest measured power value in the period.
  • Hours above 80% of peak: How many hours the load exceeded 80% of peak load, including the share of the total period and the corresponding threshold in kW. Few such hours mean you are paying demand charges for only brief spikes.

For feed-in meters the values are named Base Generation and Peak Generation accordingly.

The Load Duration Curve

The Load Duration Curve sorts all readings in the period from highest to lowest load. The x-axis shows the % of time, the y-axis shows power in kW.

Load Duration Curve: from peak load (left) to base load (right), a dashed line marks 80% of peak load.
Load Duration Curve: from peak load (left) to base load (right), a dashed line marks 80% of peak load.
  • Far left: Your peak load, the highest measured value.
  • Far right: Your base load, the lowest continuous power.
  • Steep curve: Your load fluctuates heavily, with a few high peaks and then a rapid drop. Typical for buildings with individual large consumers.
  • Flat curve: Your load is evenly distributed. Typical for buildings with a constant base consumption.

A dashed line marks 80% of peak load. The narrow area above it shows how rarely the highest peaks occur. The area under the entire curve equals your total energy consumption in the period.

Top 10 Peaks

Below the curve we list the ten highest load peaks with exact timestamps. Each entry represents a single measurement interval, either 15 minutes, one hour, or one day depending on resolution. With multiple meters we also show the meter and location. This helps you find out when the peaks occurred and what might have caused them, for example simultaneously switched-on equipment or motor inrush currents.

For experts

The Load Duration Curve is a standard tool in energy management. It helps with the assessment of:

  • Peak shaving: Can load peaks be reduced by shifting or storage? The steeper the left flank, the greater the savings potential on demand charges.
  • Demand-side management: What share of the load is shiftable? The range between the peak and median consumption shows the theoretical potential.
  • Network tariffs: In Austria, the demand charge in the network tariff is based on the highest quarter-hourly average values. Targeted reduction of the top peaks can lower network costs.
