Review of Nominations and Operational Balancing Times for Modification Proposal 461
Meeting Friday 13th September 2013
Hayley Burden

2. Nominations and Operational Balancing - Background
UNC Section C Nominations – 6 clauses containing time references
UNC Section D Operational Balancing and Trading Arrangements – 10 clauses containing time references
Predominantly shipper/trader related processes, therefore views of those users are key in making the right decisions around any proposed changes

3. Nominations NG NTS Recommendations
D-1 Nomination times are suitably detached from the start/end of the day to not be affected by the change to the Gas Day
Last time for shippers to renominate on the Day (D 04:00) is impacted by new Gemini outage time (03:00-04:59)
Times related to Calorific Value Information are not expected to be affected from the change to the Gas Day
Times related to Trade Nomination submissions are affected by the new Gemini outage time
Time related to Trade Nomination rejection impacted by new Gas Day start time

4. Operational Balancing & Trading Arrangements NG NTS Recommendations
Most times associated with Trading Arrangements and Market Transactions are not expected to be impacted
Last Contract Renomination time in relation to the physical market is impacted by the new Gemini outage time
Last time for acceptance of market offers will also be impacted by the new Gemini outage time
Transaction effective time on the Market Offer Date recommended to align with the start of new Gas Day
