Dear Market Participants,

We invite you to join our upcoming test session for the new monthly products for the 3 borders :

→ Ukraine-Slovakia: UA <> SK

→ Ukraine-Romania: UA <> RO (integrating new border)

→ Ukraine-Hungary: UA <> HU

The test is scheduled for 29th and 30th of October 2025.

This event presents an excellent opportunity for you to engage in dummy auctions, thoroughly test your bid files and seamlessly integrate eCAT’s output files into your applications.

The target Go-Live date for the Project is 15th December 2025 for the for the January 2026 monthly auctions.

The scope of this test session encompasses long-term auctions: Monthly January 2025

To register for the test session, kindly send us the following information to helpdesk@jao.eu:

• Company name
• EIC code
• Username (if you are already registered in eCAT) or your full name
• Email address

The registration for this test will conclude on 27th of October.

Please note that all the Long Term entitlements will be granted by default to all the registered market participants.

Further details concerning the exact date, timing, and the specific scenarios to be tested will be communicated in a subsequent notice.

Should you have any questions or wish to share feedback, please do not hesitate to reach out to us.

Your insights and participation are highly valued as we work together to enhance this process.

Best regards,

JAO Operations Team
