Capacity Peaks

Next to energy and power curves, the NET2GRID platform is able to provide values for peak offtake in a particular month, so called capacity peaks.

The clearest use case for this feature is peak shaving. E.g. in case energy retailer tariffs are based on peak usage, users would like to flatten their offtake curve. For this purpose capacity peaks indicate when many appliances are turned on at the same time and when solar production is low. This helps users shift energy consumption to other moments in the day.

The monthly capacity peak is calculated by taking the nett offtake, i.e. the offtake minus injection for each quarter hour in kWh. This amount is multiplied by 4 to get an hourly capacity peak in kW. The highest hourly capacity peak in the month is the monthly capacity peak.

The following example call for the monthly capacity peak endpoint

GET /v2/capacity-peak/electricity/mains/2022/12
Authorization: Bearer <access_token>

returns the capacity peak for the month of December 2022:

    "status": "ok",
    "data": {
        "usage": 2152,
        "capacity_peak": 8.608,
        "start": "2022-12-04T17:30:00+01:00",
        "end": "2022-12-04T17:45:00+01:00",
        "timestamp": "2022-12-13T16:18:00+01:00"

As you can see, a capacity peak of 8,6 kW is calculated and the quarter hour in which this peak happened is also returned: on 4-12-2022 from 17.30 to 17.45 hours.
