Pilot study on ancillary services from resources with variable production or consumption

Svenska kraftnät invites market participants to a collaboration on the conditions for delivering ancillary services and remedial actions from resources with variable production or consumption.

In February 2022, Svenska kraftnät will initiate a pilot study on the delivery of ancillary services and remedial actions from resources with variable production or consumption.

The pilot study offers market participants an opportunity to explore their own conditions for delivering ancillary services from resources with variable production or consumption, in collaboration with Svenska kraftnät.

The project will start in early 2022 and continue for the rest of the year. We are currently looking for market participants who are interested in participating in the pilot study, going through the proposed test procedure and contributing to the further development.

Collaboration key to enable more players to partake in the market

The purpose of the pilot study is to collaborate with the industry to create an understanding of the conditions for variable resources to contribute with ancillary services and to investigate how the prequalification process should be performed for resources with variable production or consumption.

Market players participating in the study will get the opportunity to present their proposals of new technical solutions. This may clarify the need to adjust the proposal for the prequalification process.

The aim is to have a mix of market players and types of technologies participating in order to get an overall and nuanced picture of the feasibility of the requirement verification process, and to exchange experiences.

Ancillary services and remedial actions within the scope of the pilot study

The study will include Frequency Containment Reserves (FCR-N, FCR-D upwards and FCR-D downwards), Frequency Restoration Reserves (aFRR and mFRR) as well as the remedial action Fast Frequency Reserve (FFR). Relevant types of technology includes, but is not limited to, wind power, solar power and consumption resources with underlying power variations.

Terms for participation

The participant chooses what market or markets to participate in

Participation in the pilot is voluntary. Participants partake in the market for one or more of the ancillary services FCR-N, FCR-D upregulation, FCR-D downregulation, aFRR, mFRR and/or remedial action FFR. If relevant, the corresponding criteria for the frequency-related functions in RfG (FSM and LFSM) may also be discussed in connection with the pilot study.

Approval of initial simplified prequalification grants access to the market

Units/groups that participate in the pilot and undergo an initial simplified prequalification with approved results may participate in the relevant markets during the pilot study in accordance with the ordinary rules. There will not be any special compensation paid in addition to the ordinary compensation on the market.

It is possible to participate in the pilot study without undergoing a prequalification, but in that case, the resource may not participate on the market.

Test results can be used towards a regular prequalification

Units/groups participating in the pilot study may use the test results obtained to undergo a complete prequalification in connection with the end of the pilot.

Test of new support document for market participants

Svenska kraftnät will issue a support document to the market participants with variable production or consumption who partake in the pilot study. The document describes the principles proposed by Svenska kraftnät on what a market participant with variable resources must be able to verify in connection with a prequalification which is required before the resource can be approved to deliver ancillary services. The document will be further developed in connection with the pilot study and then be used in future prequalifications.

Do you want to participate in the pilot study?

Svenska kraftnät is now looking for market participants who want to partake in the pilot study. Do you want to participate? Send a notification of interest no later than 28/2 2022 to our FCR e-mail: fcr@svk.se. The notification of interest shall contain a brief description if the intended resources, as well as a rough estimate of when prequalification can be performed. Mark the e-mail by writing "Pilot for variable resources" in the subject line.

Please note that you need to send all messages regarding the pilot study to the FCR e-mail address, regardless of what ancillary service you are interested in partaking with.

Start-up meetings with interested participants

Svenska kraftnät will contact all market participants who have registered interest to partake in the study to book individual introductory meetings in March. We will then discuss and specify the structure of the tests, your conditions for participation, the units you can contribute with, and similar.
Svenska kraftnät will also hold a joint start-up meeting with all participants before the start of the pilot study.

More information and contact

If you have any questions regarding the pilot study, please don’t hesitate to contact Svenska kraftnät by mail to the FCR mailbox: fcr@svk.se. Please note that all messages regarding the pilot study are to be directed to the FCR e-mail, regardless of the ancillary service concerned.
