Like the Plan model above, Plan-extended is a model that picks values from the load series and uses them as a forecast. Once these values run out, you can choose to use the last existing value as a future constant forecast. This is done by specifying a negative value in “Adjustment period (h)”. If instead you specify a positive value, during the hours you have specified, the forecast will undergo linear approximation to the value you entered in “Value”. After these hours, the forecast will constantly follow this value.

For “plan – extended” the quarantine settings also applies, so that if you entered 2 in “Quarantine (h)” the last two existing values in the .el file will be ignored.
