Leading service provider for Transmission System Operators (TSOs) in the European electricity market.

We would like to inform you that an amendment of the following allocation rules with effective date 1^st May 2025 have been published on our website:

• Allocation Rules for Forward Capacity Allocation on Swiss borders
• Rules for Daily Capacity Allocation on Swiss borders
• Allocation Rules for Intraday Capacity Allocation on Switzerland – Italy Border

Please note that these rules are released on behalf of the transmission system operators (“TSOs”) for information and are pending approval by the relevant National Regulatory Authorities. The rules will be binding once National Regulatory Authorities have approved them.

For your reference, you may find the track changes versions and the summary tables under the section “Public consultation” on our website (ID, DA, LT).

Best regards,

JAO Operations Team

Dear Market Participants,

Please find attached the nomination information related to the member tests for the SDAC 15MTU project.

As communicated by the TSOs and NEMOs, member tests will begin on 7th April 2025. During the first week of these simulation tests, both partial and full decoupling tests will take place, and TSOs will facilitate testing of the nomination process. The attached table provides details on the borders where shadow auctions will be organized, the resolution used for nomination rights documents, and the nomination deadlines.

To ensure a smooth nomination process, we strongly recommend that you contact the TSOs to confirm they have all necessary information. While JAO has already provided the TSOs with your company name and EIC code, they may also require your system’s email address and testers’ contact details.

For normal days, the nomination will follow production processes and will therefore be handled by CCPs.

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

Kind regards,

JAO Operations
