We would like to inform you that as per TSOs request, the 2026 Auction Calendar has been updated on the corridor IFA1, IFA2 and VKL.

For more details please refer to the Auction Calendar on our webpage http://www.jao.eu/auctions#/calendar/table to find its latest version.

We are pleased to invite you to participate in the upcoming new fourth round of LTFBA test sessions on 22nd  of September with a possible rerun on 23rd of September in case it’s needed.

The focus will be the same as previous tests:

• Yearly Auction Test Session (CORE & Nordic Regions)
• Monthly Auction Test Session (CORE & Nordic Regions)

These sessions are intended to provide Market Participants with the opportunity to:

• Familiarize themselves with the LTFBA auction setup
• Navigate the platform and explore its functionalities
• Submit and manage bids within the tool

Please note that these sessions are dedicated to practical testing within our Auction tool's test environment, allowing participants to actively interact with the system and validate their processes.

Registration

Market Participants interested in joining are kindly requested to register by sending an email to helpdesk@jao.eu with the following information:

Further details, including access information and session timelines, will be shared with registered participants ahead of the test dates.

Should you have any questions, please do not hesitate to contact us.

We look forward to your participation.
