The IT services firm will also be responsible for EDF's back-office SAP systems.
EDF, which has 11,300 employees, provides gas and electricity to five million customers in London and the East and the South East of England. The company, which was formerly London Electricity, made a number of acquisitions including SWEB Energy and Seeboard Energy.
As a result, EDF inherited a complex IT infrastructure including IBM z900 series mainframe hardware that runs the AIX operating system, DB2-based databases, Unix-based Oracle databases and a mixture of servers running operating systems such as Sun Solaris and Hewlett-Packard OpenVMS.
LogicaCMG will provide application management and support for all EDF's Networks Branch business systems. It will control, monitor and maintain key network applications used by 3,500 staff in the branch.
Andy Hooper, EDF's IT director said, "A highly reliable performance is essential when it comes to systems that support the power distribution network. In effect the IT team is helping to keep the lights on.
"LogicaCMG's proposition meets our demanding requirements at a realistic price."
As part of the deal, LogicaCMG will also be responsible for EDF's SAP system which covers work management, materials and warehouse management, procurement, finance and HR across the company.
EDF's datawarehouse team recently worked with Israeli company Corigin to extract data from its IBM mainframe into an Oracle datawarehouse, so that information can be consolidated and accessed more efficiently.
