Is ForecastInterval.range relative to ForecastInterval.perKwh or ForecastInterval.spotPerKwh ?

[CarlLusty]

I have noticed instances of ForecastInterval where ForecastInterval.perKwh is outside of ForecastInterval.range (when reported). For reference, I've included an example below.

The easy answer may be that I have assumed wrong and ForecastInterval.range refers to the potential value of ForecastInterval.spotPerKwh and not ForecastInterval.perKwh.

I checked the documentation but it isn't all that clear to me which it is. Docs:

• ForecastInterval.range: When prices are particularly volatile, the API may return a range of prices that are possible.
• ForecastInterval.range.min: Estimated minimum price (c/kWh)
• ForecastInterval.range.max: Estimated maximum price (c/kWh)

Is ForecastInterval.range relative to ForecastInterval.perKwh or ForecastInterval.spotPerKwh?

Thanks, Carl.

It's relative to the spot price
