CP1383 – Upgrade of NHHDA and EAC/AA systems to Oracle 11g

Formal title: Upgrade of NHHDA and EAC/AA systems to Oracle 11g

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


The current version of NHHDA and EAC/AA applications that Elexon provide to Party Agents run on Oracle 10g, for which Oracle Corporation ended application support in July 2012, meaning these systems are now running on unsupported platforms. An upgrade to Oracle 11g is therefore required.


CP1383 was raised and issued for industry impact assessment via CPC00719 on 26 October 2012, with responses due back on 22 November 2012.

At its meeting on 4 December 2012 the SVG recommended that the Panel approve CP1383, a decision they could not make as the implementation cost is above the £150k SVG approval threshold. On 13 December 2012, the BSC Panel noted the SVG’s recommendation  and approved CP1383 for implementation as part of the June 2013 Release.
