On this page we share answers to some of the most frequently asked questions in order to help market participants.

Frequently Asked Questions

  • 1. Settlement

    This category contains Settlement related questions.

    • 1. Nordic Imbalance Settlement Model utilises the Nordic calendar in all reporting schedule (CET) – how does this reflect to content of the message?

      In general, messages utilise CET-time but Finnish market participants may use EET-time if they wish so. In this case it is their responsibility to manage the message gate-closure times which are set according to CET-time. Reporting and imbalance settlement in NBS-model are always performed and invoiced from BRPs in CET-time.

    • 2. Do Bilateral Trades include Elspot- and Elbas-trades or will they be reported separately?

      Elspot- and Elbas-trades are not included in Bilateral Trades and therefore have to be reported separately.

    • 3. How are we supposed to handle structural changes in those cases where the change is valid immediately (i.e. mottagningsplikt) but structure changes in Online Service can only be added with a validity 3 days later?

      We have been notified by several DSOs that the current gate closures in the NBS model are too strict to handle these situations and that it will result in an increased number of bilateral corrections. eSett and the involved TSOs are currently reviewing the set gate closures and will communicate any changes as soon as possible via eSetts established communication channels.

  • 2. Handbook

    This category contains Handbook related questions.

    • 1. Are there different language versions of Handbook available?

      Yes, The Nordic Imbalance Settlement Handbook have been translated into Norwegian, Swedish and Finnish languages. All versions are available here.

    • 2. How often the Handbook will be updated?

      New versions are updated approximately twice a year or every time major changes are being made.

  • 3. IT & Messaging

    This category contains IT & Messaging related questions.

    • 1. What market party abbreviations shall be used in the NBS-messaging?

      Regarding the market party abbreviations, either EIC-codes, GS1-codes or national codes can be used. If the market party operates in several countries, it is necessary to use either EIC- or GS1-codes since they are internationally approved codes.

    • 2. Swedish market participant can see in Online Service hourly values for profiled consumption and losses, who has reported those?

      Svenska kraftnät is reporting profiled consumption and profiled losses to eSett on behalf of the Swedish DSOs.

    • 3. Imbalances in our MGA are almost never “0” (zero). How can this be when both we and also adjacent MGAs are reporting correct values.

      As a service to the Swedish DSOs, Svenska kraftnät has decided to continue to receive the load profile shares from Swedish DSOs and based on those calculate and divide the profiled consumption per MGA and BRP (like today). In these calculations rounding errors could occur resulting in that the balances are not equal to “0” but very close to “0”.

    • 4. What kind of information is eSett reporting back to the market parties?

      eSett is as a standard reporting back acknowledgements on all messages sent to eSett. eSett is also reporting back information on exchanges, bilateral trades and settlement results depending on the market role. Depending on the need the market parties can choose to subscribe to data packages or download information via Information Service. More information can be found in the “Communication guideline” to be found here: https://www.esett.com/materials/communication-guidelines/

    • 5. What is included in the data packages and how often are they sent?

      The data packages are tailored per market role and are sent on a regular basis. More information on the different data packages available and the frequency of distribution can be found here: https://www.esett.com/materials/communication-guidelines/

    • 6. How does the reporting of MGA Exchanges and Bilateral Trades work and what are the principles regarding their confirmation reports?

      To find a detailed description with examples please take a look at a specific document describing these concepts here.

  • 4. Finance

    This category contains Finance related questions.

    • 1. What exactly does mean "the last seven settled days" in the collateral formula?

      "The last seven settled days" refers to settlement data from the last seven days which can be seen as final. In other words, the last seven days whose reporting window has been closed.

    • 2. Could you specify the time schedule of the collateral calculations? Will public holidays affect on the calculations?

      The collateral is always calculated on Monday by 13 CET. In case Monday happens to be a holiday, the calculation of the collateral is postponed to next working day. In other words, regardless of the holidays, the collateral is always calculated on invoicing day. If there appears to be significant changes in the requirements of the collaterals, the changed information can be published on any day.

    • 3. The reporting of data is a daily process but the invoicing is performed only weekly. How will this work?

      BRPs report data every day and eSett will send the invoices regarding the whole week once it is complete.

  • 5. Commissioning

    This category contains Commissioning related questions.

    • 1. When will the commissioning plan be published?

      eSett has during the parallel settlement period provided handbooks in local language describing the NBS model, provided an Online Service user guide to support the work in the system and held several clinics (Skype meetings) to support the daily operations. Any education except from the above will not be provided before go-live.

    • 3. In one of the infoletters you have written about “Assign/Terminate Retailer”. What is this?

      This is a description of how a power plant can be activated and inactivated from one day to another but still enabling to use the same name and code of the power plant. For Swedish DSOs this function is very useful in the case of the aggregated series for production units below 1 MW.
