Addition of counterparty nomination in confirmations (18G)
In our October newsletter, we informed you about the inclusion of the original counterparty nomination in the confirmation (NOMRES) messages. Given that there is now no longer a lack of clarity, like there was back in October, we intend to add the sending of the nominated values by the counterparty ('the 18G feature ') to the Edig@s version 5.1 NOMRES messages on TTF as of 1 July 2020. Please find below a brief explanation and a request to check your systems.
At virtual network points, it is compulsory in Edig@s version 5.1 to include the (original) nomination of the counterparty in the confirmation (NOMRES) messages, alongside the actual confirmation. The codes used in the NOMRES message indicate the meaning:
- 16G: confirmed values to shipper
- 18G: nominated values by counterparty
After consulting with the Edig@s working group, we were able to remove the lack of clarity on the flow direction, and GTS has now also been able to implement the 18G feature. For Edig@s version 5.1, the flow direction of nominations of the counterparty is the same as the flow direction of the shipper’s confirmation both for entry (Z02) and exit (Z03). The figure below shows an example of the current, version 5.1, TTF Edig@s message into which the 18G feature has been incorporated.
Although tests conducted with a number of market parties did not find any issues, we kindly ask you again to check your current systems with respect to validation and processing of confirmation messages, so as to ensure that this will not pose any problems as of 1 July.
