Descriptions of imbalance settlement calculations

This page describes in more detail how time series are selected for imbalance settlement calculations. In the descriptions of calculations, input refers to data needed to calculate an individual imbalance settlement calculation. Other selection criteria refers to criteria that are based on which of the time series is selected as the basis for the calculations. Fulfillment of these criteria is verified by time-step. Only time-steps from the selected time series for which all the criteria are met are included in the calculated sum. In calculations based on accounting point information, especially the metering method may change by time-step. In practice, the accounting point type cannot change and the metering grid area to which the accounting point belongs changes very rarely.

MGA exchange sum

Description:

Exchange point sum refers to the total electricity transmission between two metering grid areas that is calculated from the metering time series of the exchange points between the two metering grid areas in question. Exchange point sum includes information about which metering grid area is the ‘In Area’ (the area electricity is transmitted to) and which is the ‘Out Area’ (the area electricity is transmitted from).

Exchange point sums are calculated between all two metering grid areas, which have at least one exchange point metering.

Datahub’s balance settlement type code: BI18

Input:

• Out Area

• In Area

Other selection criteria for metering time series to be added:

• Metering point type = Exchange point

Metering grid area losses

Description:

Transmission losses of the metering grid area in accordance with the official imbalance settlement period.

Metering grid area losses are calculated based on other calculated sums of the metering grid area using formula:

Metering grid area losses = Connection point sums − metered sum deliveries − profiled sum deliveries − metered own consumption sums − profiled own consumption sums + small scale production sums + production unit productions

Datahub’s balance settlement type code: BI07 and BI08
