Guidelines for submission of operational and availability schedules

OPERATIONAL SCHEDULES 

Guidelines for submission of operational schedules

Following revisions to regulations C3 and F, the submission of operational schedules will be changed to ensure that Energinet has all the information necessary to underpin the common European grid model.

Schedules must be submitted in a new format which is described in more detail in our  Implementation Guide (link to the right).

Based on dialogue from our consultation up to and at the stakeholder meeting on 31 October 2022, we have made changes to the time series that must be submitted so that a time series containing all production or consumption with relevant mFRR (regulating power) must be submitted. If mFRR is delivered, a time series indicating the mFRR delivery must also be submitted. This change has been made in the Implementation Guide, and the change has been submitted for approval with the authorities (Danish only). Sections 5, 6, 6a, 8, and 13 of C3 have been adjusted with the new time series requirements.

Operational schedules and availability will be introduced in steps; details on availability are now found at the bottom of this page.

We are working to introduce the new rules for operational schedules in April 2023, parallel to the discontinuation of power imbalance settlement, changes to schedules for RE, and corrections for mFRR activation, which have been submitted for approval with the Danish Utility Regulator. The new mFRR energy activation market (Danish only) will be implemented at the same time.

We are ready to test submission and control of – as well as acknowledgement of – operational schedules.

However, requirements submitted for approval for direct lines, for submission of structural data, and for selecting DSO-connected weather-dependent RE facilities for submission of power schedules instead of shutdown schedules will not be implemented in April. Moreover, requirements for the submission of operational schedules for large demand facility will not be implemented in April either (operational schedules for demand facilities that deliver mFRR energy must still be submitted).

TEST OF SUBMISSION OF OPERATIONAL SCHEDULES

It is possible to test schedule submission and acknowledgement receipts via an ECP connection. How to configure ECP correctly is described on the How to get started with ECP page.   

Energinet will check the format and content of the operational schedule and via ECP return an acknowledgement receipt and - if there are no errors in the submitted schedule - an approved schedule from Energinet to the balance-responsible party. Tests with checks of merged schedules are not possible yet. 

Tests are carried out with the following changes (included in the Implementation Guide): 

  • Discontinuation of power imbalance settlement 
  • Power schedules for transmission-connected RE 
  • Shutdown schedules for each individual RE facility > 10 MW 
  • Total shutdown schedules split into solar and wind power 
  • Supplementary time series for activation of mFRR 
  • Process for acknowledgement receipts on subsmission of schedules has changed 
  • Process upon mFRR activation has changed (see mFRR EAM) 

and 

  • Batteries are considered consumption or generation facilities, respectively, depending on operation mode 
  • Total schedules broken down onto fuel types 
  • Large generation facility are split onto generators if these vary 
  • Submission is done via ECP 
  • Submission format, CIM 

One supplementary time series for activation of mFRR must be sent, indicating upward and downward regulation, respectively. This time series must be indicated by signs (+/-). The Implementation Guide has been updated on this topic. 

Content checks include whether the balance-responsible party has sent the relevant forms to match registered master data and that the maximum limit is not exceeded. The aim is for the basis of this check of operational schedules to be available to the balance-responsible party on a portal. 

This portal, Electricity Market Service, showing the basis for submitting operational schedules and submitted schedules, is now accessible; we will add balance-responsible parties to the system upon request. 

As the test environment is not fully integrated with all Energinet systems, it is possible for each individual balance-responsible party to request an introduction prior to running tests. Here, we can present the functions to be tested and those that we expect to introduce later on. 

When you are ready for a test, book a time slot 1-2 weeks in advance (Danish or English) at electricitymarket@energinet.dk to give us the best possible chance to provide feedback before and during the test.

COMMUNICATION CHANNEL OPTIONS

There will be two possible communication channels between the market participant and Energinet:

  • ECP/EDX channel
  • Electricity Market Service

Currently, it is only possible to test exchange of schedules via the ECP channel. When we open up more options, we will announce it here and send out news via our Danish Rules and Regulations newsletter in both Danish and English (please sign up on our Danish site).

Electricity Market Service will only be able to exchange schedules a few times a day. This does not support regular schedule changes and can only be used for this if the ECP connection breaks down.

In future, Electricity Market Service will be used to share information with the balance-responsible parties as a replacement for the information available on the current self-service portal.

SAMPLE FILES

We have created an example file (SampleResourceSchedule), which, however, is still being reviewed in Energinet. The file can be downloaded under Implementation Guides on the right-hand side in a zip format, which also includes a two-page explanation (Resource Schedule Example).

The file formats are defined by ENTSO-E. The ENTSO-E zip.file, also available under Implementation Guides on the right, contains schema files, and the following two files are useful when setting up the correct schedule format.

Planned Resource Schedule is IEC 62325-451-7. Filnavn: iec62325-451-7-plannedresourceschedule_v6_2.xsd - Note: file updated in April 2022
Resource Schedule Confirmation is IEC 62325-451-7. Filnavn: iec62325-451-7-resourcescheduleconfirmation_v6_1.xsd - Note: file updated in April 2022

The zip file also includes a file for setting up acknowledgement of receipt. This is the file: iec62325-451-1-acknowledgement_v8_1.xsd

To create sample files, we recommend using, for example, XMLSpy to generate XML files. In XLPSpy, you can use the XSD file as your starting point and have it create your sample file, and you then insert the correct attributes that we need in the file.

If you unzip the attached file on a file drive, you can load XSD files directly into XMLSpy and use it as the basis for your sample files.

RELEVANT RULES

Energinet have changed market regulations C3 and F, and these changes have been registered with and approved by the Danish Utility Regulator (see link on the right). The changes applicable the submission of operational schedules and availability are described in regulation C3, while the change to regulation F merely states that this regulation will no longer be applicable to the exchange of operational schedules.

Applicable regulations can be found here (Danish only):

AVAILABILITY 

GUIDELINES FOR SUBMISSION OF AVAILABILITY

Following revisions to regulations C3 and F, the submission of operational schedules and availability will be changed to ensure that Energinet has all the information necessary to underpin the common European grid model. The former 4-week schedules and daily forecasts will no longer apply when the submission of availability moves to the new system.

Schedules must be submitted in a new format, as described in more detail in our Implementation Guides (links to the right).

Operational and availability schedules will be introduced at different times. The new availability rules, which will replace 4-week schedules and daily forecasts, are not expected to take effect until after the new requirements for the submission of operational schedules (i.e. later in 2023) and will involve a prior test process.

Tests of availability submission are not yet available; Energinet expect the process and set-up to resemble the above for operational schedules.
