In order to participate in the balancing markets, a provider of FCR or FRR shall demonstrate that the technical requirements for the reserve are met by performing a prequalification with an approved result.

Information about the prequalification process

Before an application for prequalification is made, we recommend you to have a look at the page Information about ancillary services.

A new prequalification is required for

  • every unit or group you want to use to provide reserves
  • for each unit or group, one application is required for each reserve market

FCR providing units or groups shall be re-assessed

  • at least once every 5 years.
  • in case the technical requirements, endurance requirements or the equipment have changed

Summary of the prequalification process

  1. The operator in question notifies Svenska kraftnät about the scheduled date for the tests required in order to prequalify the unit/group, to ensure that Svenska kraftnät is able to attend during the tests. If required, Svenska kraftnät may request a change of the date of the tests.
  2. Tests are performed in accordance with the “Test Program Template”.
  3. A formal application is submitted to Svenska kraftnät. The application shall include the following documents:
    a. Application Document Template, and
    b. Test Report Template (the results of the completed test)
    c. Test data and additional attachments.
  4. Svenska kraftnät makes an assessment of the application. The application is rejected or approved. If the application is rejected, the operator is informed about the decision including information on any measures required in order for the unit or group to be approved.

Svenska kraftnät may request additional information during the assessment.

Submitting your application for prequalification

The application should include

  • Test report where the results of the prequalification tests are summarized for each respective reserve and unit/group (test report templates found below).
  • Logged data from the prequalification tests.
  • Additional attachments in the appendix.

How long does it take?

You will receive feedback on your application within eight weeks after it was submitted.

If the application is not immediately approved, you will need to answer the feedback and submit a revised version within four weeks after the feedback was received.

If your unit or group fulfils the criteria, the final decision will be issued within three months after you’re notified that your application is complete.

Reporting data to Svenska kraftnät

A provider of ancillary services is required to log and save certain measurement data for at least 14 days in accordance with the Balance Responsibility Agreement is only available in Swedish.

The provider can choose the format in which the data is logged during operation. However, when data is sent to Svenska kraftnät it must use the units and format given in the relevant documents for each reserve. In these documents it is described which measurements should be conducted and ready to be provided. In addition, the documents clarify the correct format for reporting these measurement data.

Company secrecy

The application and all related documentation shall be sent to Svenska kraftnät by using Svenska kraftnät’s services for safe sharing of documents: Alfresco or Deaddrop. In the case of using Deaddrop, the applicant will receive a temporary Deaddrop link after notifying Svenska kraftnät that the application is complete and ready to be sent in.

As a general rule, all documents that are submitted to Svenska kraftnät are public, but in some cases information may be classified.

The applying company is therefore recommended to state which information in the application can be considered as sensitive from a secrecy point of view, and for what particular reason the company may be harmed if the information is disclosed.

Svenska kraftnät is not bound to follow the assessment of the applying company but will do an independent review in each case.
