EDF – STERIA
SID Linky project
The objective of the Linky SID project (Linky Deployment Information System) is to build the IT infrastructure necessary for the replacement of electricity meters by the new Linky smart meter. The beneficiary of this project is ERDF (Electricité Réseau de Distribution France), a subsidiary of EDF. Steria has been entrusted with the implementation of this project.
Total project duration : 10 months
LThe total cost of the project was 200 man days.

Problematic
In view of the liberalisation of the electricity market and to homogenise the existing fleet of electricity meters (more than 23 models), ERDF designed the new smart and communicating meter named Linky. It will be deployed in all households in France between 2012 and 2017. A major IT infrastructure is required to complete this long deployment operation.
The main objectives of the project were :
- Manage the planning of interventions by ERDF technicians and external service providers and their follow-up
- To provide the technicians carrying out the interventions with an on-board computer tool to produce their intervention reports.
Mission statement
To integrate the “Mobility” team, which is supposed to develop the embedded tool intended for the realization of customer interventions by technicians. Tasks carried out during the mission:
- Study of needs and constraints
- Business concept modeling
- Technical design
- Setting up the technical and software architecture of the system to be developed
- Realize functional mock-ups for the validation of technical concepts
- Development of the application’s screens in Agile Methodology
- Unit and integration tests
- Performance optimization
- Investigations and correction of anomalies
- Packaging and deployment on test and acceptance platforms
Organization
Integration of a Steria team of 5 people
