1. Demand Estimation Sub-Committee NDM Sample Data - reminder
22nd September 2014

2. Background
At the DESC TWG meeting in May’14 an action was created for:
i) shippers to supply NDM sample data
ii) Xoserve to provide a data file specification
A draft data file spec was presented at July’14 DESC where some clarifications were identified
A revised data file spec (version 2.0) was published with the Aug’14 DESC material

3. Reminder of Next Steps
If shippers can provide data to support the 2014 Autumn Analysis, Xoserve require NDM sample data covering period 24th September 2013 to 7th October 2014, by Tuesday 21st October
Going forward there is a preference to receive data on a more frequent basis (i.e. weekly / fortnightly / monthly)
