Overview

Use Case: Reporting data for Imbalance Settlement

Imbalance Settlement is run daily and is performed per usage date. Reporting to ISR for the usage date D will normally be done on D+2 to D+5. Elhub will freeze the values and send the final report to the ISR on D+5, but can postpone sending the final report until D+13 in the case of severe errors.

A preliminary report is sent to the ISR before 10:00 D+2. The final report is reported to ISR before 12:00 D+5. The deadline set by the ISR for the final report is 12:00 on D+13. 

Elhub reports the following to the ISR for the Imbalance Settlement with hourly resolution:

  • Production per Metering Point
  • Exchange between neighbouring MGAs
  • Aggregated hourly metered consumption per Balance Supplier in each MGA
  • Aggregated hourly profiled consumption per Balance Supplier in each MGA
  • Hourly Metered Grid Losses in each MGA (including reference to Balance Supplier) *)
  • Hourly Profiled Grid Losses in each MGA (including reference to Balance Supplier) *)
  • Hourly Metered Consumption in Pumped Hydro (including reference to Balance Supplier)
  • Hourly Metered Consumption in Pumped Storage (including reference to Balance Supplier)


*) For MGA with only hourly metered metering points, grid loss is "Metered." For MGAs with profiled metereing points, grid loss is "Profiled."  

For more details on reporting to ISR, see eSett Handbook. The same set of data is also made with the relevant parts to Balance Responsible Party, Balance Supplier. 
A BRS-NO-502 message is sent to Balance Supplier and Balance Responsible Party every day for every D+x day. The messages contain all aggregated series related to the Balance Supplier/Balance Responsible Party.  The Balance Responsible Party will get a copy of the messages sent to their Balance Suppliers and a separate message with aggregated sums for the Balance Responsible Party per MGA.

In addition the Balance suppliers will get access to the same aggregated data in Elhub Web Portal.

Process Flow and Information Exchange

Sequence: Reporting data for Imbalance Settlement

Starting state

The process is time triggered and will normally run each day between 07:00 and 12:00, D+1 around 07:10, D+2 to D+4 around 08:40, and D+5 around 10:00. Elhub will freeze the values and send the final report to the ISR on D+5, but can postpone sending the final report until D+13 in the case of severe errors

Process Sequences

This refers to BRS for ISR/eSett [4]. 
The process is time triggered. The preliminary report should be finished and reported to the ISR before 10:00 D+2. The final report should be finished and reported to the ISR before 12:00 D+5. Data is only reported if there are no validation errors or when the validations are manually approved.
Elhub can perform additional reporting to ISR at any time during the day on demand or time triggered. 
Elhub can also start aggregating hourly values at different times. 
Elhub performs the following aggregations with hourly resolution:

  • Production per Production Unit
  • Total exchange between neighbouring MGA
  • Aggregated consumption for hourly settled metering points per Balance Supplier in each MGA


The aggregated time series can be sent to the ISR as soon as they are complete and approved. 

Elhub calculates the Grid Losses and Adjusted Load Profile (JIP) for the MGA. Elhub calculates Preliminary Volumes per hour for all profiled metering points in the MGA. These will be aggregated per Balance Supplier in each MGA. Grid losses and aggregated profiled consumption per Balance Supplier in each MGA is sent to the ISR.


The following consumption should be reported separately:

  • Consumption in Pumped Hydro
  • Consumption in Pumped Storage (not connected to specific production unit)


The imbalance settlement process is run daily D+1 - D+5, but data is only reported to the ISR on D+2 and D+5. The last version of each time series used in the report to the ISR is marked in the database to be used in reconcilliation. All time series sent to the ISR are also sent to the respective Balance Responsible Party and Balance Supplier, as aggregated values per MGA. The Balance Responsible Party will get a copy of the messages sent to their Balance Suppliers and a separate message with aggregated sums for the Balance Responsible Party per MGA.

The following aggregation will be sent to the relevant Balance Supplier / Balance responsible Party:

  • SE05 - Sum supply of last resort consumption per MGA
  • SE07 - Adjusted Load Profile per MGA
  • SE10 - Sum consumption for Balance Supplier per MGA (Pumped consumption types excluded)
  • SE11 - Sum production for Balance Supplier per MGA
  • SE12 - Sum consumption for Balance Supplier for profiled metering points per MGA
  • SE13 - Sum consumption for Balance Supplier for non-profiled metering points per MGA (Pumped consumption types excluded)
  • SE15 - Sum pumped consumption per Balance Supplier per MGA
  • SE16 - Sum pumped storage consumption per Balance Supplier per MGA
  • LS01 - Grid loss, is sent to the Balance Supplier for Loss.

In addition to a copy of what their Balance suppliers get, the relevant Balance responsible Party will receive:

  • SE08 - Sum consumption for Balance Responsible Party per MGA (Pumped consumption types excluded)
  • SE09 - Sum production for Balance Responsible Party per MGA
  • SE17 - Sum pumped consumption per Balance Responsible Party per MGA
  • SE18 - Sum pumped storage consumption per Balance Responsible Party per MGA
  • SE21 - Sum consumption for Balance Responsible Party for profiled metering points per MGA
  • SE22 - Sum consumption for Balance Responsible Party for non-profiled metering points per MGA (Pumped consumption types excluded)

In addition the Balance suppliers will get access to the same aggregated data in Elhub Web Portal.

Validation Rules

In this process there is only Elhub sending messages. No messages will be received for validation.
