DR1179-Cessation of Eligible Cust Files on ESBN Extranet

RMDS became aware that Market System redundancy existed in relation to the Eligible Customer Files (ECF) and the
Downloadable Meter Point Files (DF). RMDS undertook to analyse the possible redundancy. The objective of the analysis
was to compare the two systems, the current use of the systems and the maintenance path of the systems.

Based on the analysis of usage and MP option feedback, the Option chosen was Option 3 – Cease the provision of the EC files
on the Extranet without adding the fields to the Downloadable Files apart from Meter Category Code which is scheduled to be
provided with the delivery of MCR 1151 in the 2015 Non-Schema Release.

The cessation of the provision of the two files on the Extranet with take effect on 1st September 2016 – one month after the
delivery of MCR 1151 in the 2015 Non-Schema Release. The Eligible Customer Files (2) will no longer be available for MPs to download
from the Extranet. However, ESBN will continue to produce the files for 6 months after this date and can be requested by MPs if required.
