Modification 15 Gas Day Change

This proposal is being made to implement the requirements of the Capacity Allocation Mechanisms (CAM) Regulation (EU 984/2013) which defines the gas day as operating from 05:00 to 05:00 the following day. The proposal amends the text of the GNI (UK) Limited, code to account for the change and provides for the transition on 30th September 2015 to the new gas day definition.
