We are pleased to invite you to participate in the upcoming new third round of LTFBA test sessions on 4^th and 9^th of September with a possible rerun on 10^th 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.
