Review of Physical Regime Times for Modification Proposal 461 Meeting Monday 5th August 2013 Hayley Burden

Assured Pressures & Flex Processes These are examples of physical gas use processes which will stay constant irrespective of the Gas Day changing It is believed consumers use of gas will not alter because the Gas Day has changed NG NTS view would be to retain the existing DN Assured/Agreed Pressure & Flex Capacity arrangements

UNC References – Physical Regime NG NTS have identified 28 references within the TPD and OAD relating to the physical regime NG NTS suggest that most of these times could remain as they are. 1 reference relating to revised OPNs would require moving forward an hour as it is close to the end of the gas day NTS welcome the views of Mod 0461 WG members on this assessment
