Usage

Create a load forecast

Changed on

This endpoint is used to transmit a load forecast for a subscription. A load forecast is a power curve: each data point is the average power draw in kilowatts (kW) during its 15-minute interval, not the energy consumed in kWh. Submit by 9:00 a.m. local time on the previous day to be considered in the day-ahead auction. Intervals must start at least 15 minutes in the future, be strictly consecutive, and start on a 15-minute boundary.

Request body

scope'subscription' required

Reference point for the load forecast

subscriptionstring required

Required subscription ID when scope is 'subscription'

resolution'15min' required

Time resolution of the load forecast data points

unit'KW' required

Unit of measurement for the forecast values. Load forecasts are power curves: each data point is the average power draw in kilowatts (kW) during its 15-minute interval, not the energy consumed. The energy per interval in kWh equals the value divided by 4.

Example request

{
  "scope": "subscription",
  "subscription": "sub_mi4f0oda6x9m7gcsvjk0ole1",
  "resolution": "15min",
  "unit": "KW",
  "data": [
    {
      "start": "2025-03-31T22:00:00.000Z",
      "value": 0.2
    },
    {
      "start": "2025-03-31T22:15:00.000Z",
      "value": 0.22
    }
  ]
}

Response

Positive response

scope'subscription' required

Reference point of the stored load forecast

subscriptionstring required

ID of the subscription the forecast was stored for

startstring date-time required

Start of the first forecast interval (UTC)

endstring date-time required

End of the last forecast interval (UTC)

totalnumber required

Sum of the submitted power values in kW across all 15-minute intervals. This is a checksum for the submission, not an energy amount. To convert to total energy in kWh, divide by 4.
