Background
 EU Balancing Code implementation required by October
2015
 Nominations process: timescales and rejections, etc.
 NG are not currently exercising the option to approach our NRA
for a 12 month extension
 EU CAM Code implementation required by November 2015
 ‘Single nomination’ process for bundled capacity
 EU Interoperability Code in ‘comitology’ – it was expected
that implementation would be required for October 2015
 Nominations matching process
 Data exchange

1. New Terms; and
2. Application
 Additional terms required in new Nomination process
 Rules apply in respect of each System Entry Point and
Connected System Exit Point at an Interconnection
Point (as now)
 Transitional requirements in September 2015
 For gas days up to and including 30th September 2015 –
existing process
 For gas days 1st October 2015 onwards – new process

3. Nominations and Renominations General
 ‘Single Sided’ and ‘Double Sided’ nominations
 Communications (User to Transporter)
 Acknowledgment
 Quantity types – ‘Processed’ and ‘Confirmed’
 Multiple nominations per User per Day
 Initiating Transporter and Matching Transporter role
 Matching rule publication

4. Processing of Nominations
 Submission window: D-30 to D-1 (13:00)
 Default Nomination Rule – Nominated Quantity deemed
to be zero in absence of User Nomination
 Mandatory information requirements
 Determination of Processed Quantity by NG
 Notification of Confirmed Quantity: by D-1 (15:00)
8
5. Processing of Renominations
 Submission window: D-1 (15:00) to D (02:00)
 Negative Implied Flow rate validation
 Daily nomination must not exceed the volume deemed to
have already flowed at effective time of flow rate change
 Mandatory information requirements
 Determination of Processed Quantity by NG
 Notification of Confirmed Quantity – by Hour Bar + 120
minutes
 Effective time of flow rate change – Hour Bar + 120
minutes

6. (A) Rejection
 National Grid NTS may reject Nominations or Renominations:
 Absence of mandatory information
 Not submitted by User or its User Agent
 In a Transportation Constraint, nominations above capacity entitlement
 Negative value or Negative Implied Flow rate
 Absence of a Double Sided Nomination to match against
 Absence of matching information from Adjacent Transporter
 Timing and consequence –
 User notified within 120 minutes of Hour Bar
 Prevailing Confirmed Quantity applies
12
6. (B) Revision
 National Grid NTS may revise Processed Quantity:
 In a National Grid NTS Transportation Constraint /
Emergency
To match capacity entitlement
To a value deemed appropriate (Emergency only)
In the case of multiple Confirmed Quantities, the revisions
will pro-rated
 National Grid NTS may revise Confirmed Quantity:
 Where the Adjacent Transporter has revised its Processed
Quantity
13
7. Physical or Locational Trades at IPs
 Confirmation lead time – Hour Bar +120 minutes
 Opportunity for User to provide Renomination/s up to
next Hour Bar
 In absence of such Renomination/s, National Grid NTS
will revise the previously determined Processed Quantity
 In the case of multiple Confirmed Quantities, the revisions
will pro-rated
 User may subsequently revise subject to availability of
Renomination process

Current Arrangements at Interconnection Points
Prospective Arrangements at Interconnection Points
One type of Nomination / Renomination
‘Single Sided’ and ‘Double Sided’ Nominations and Renominations
No details of User’s counterparty at IP required
Details of User’s counterparty at IP required
One Nomination per System Entry Point or Connected
One or more Nominations per System Entry Point or Connected System Exit Point
System Exit Point at the IP per User

counterparties per User
No NG NTS interaction with Adjacent Transporters at IPs NG NTS interaction with adjacent TSOs at IPs to undertake Nomination ‘matching’
process. Specification of an Initiating and Matching Transporter role.
Nomination submission period:
Nomination submission period:
D-30 to D-1 13:00 (DM Output)
D-30 to D-1 13:00. Note that the adjacent Transporters may not offer the same
D-30 to D-1 14:30 (Input)
earliest submission time.
Renomination submission period:
Renomination submission period:
15:00 D-1 to 03:00 D
15:00 D-1 to three hours prior to the end of the Gas Day
Typically 1 hour processing time
Processing time up to 2 hours
Communications as per UK Link Manual / Gemini
Communications as per Edig@s file formats or equivalent data format developed
by ENTSOG
Limited ability to reject a nomination (e.g. validation
Additional reasons for Transporter to amend or reject a nomination. Application
failure). Application of Overrun Charges for nominations

Working Towards 1 October 2015
 NG discussions with adjacent TSOs to agree
nominations framework principles and implementation
date/s - Q4 2013 onwards
 The Nomination information required in the
Interconnection Agreements (IA) will be included with the
other EU code IA changes
 NG discussions with adjacent TSOs may lead to variations
to Mod 493
16
Next steps
 What topics do stakeholders want NG to cover at the
next Workgroup on the 22nd May?
