EDF Luminus - Solution Architect Optimization & Generation



The Solution Architect is responsible for the conversion of the complete business demand for his/her domain into a fit for purpose technology & solution architecture supporting the business and IT strategy, policies and it objectives, including cross-domain integrations. This in very close collaboration with the business, other BU's, Enterprise Architecture and Business Engagement Management to ensure E2E coverage & qualitative intake at all levels (business, application, data, and technology architecture).


Operating Environment  (For example purpose of the entity in which the jobholder acts, strategy, plan, specific policy, economic model and/or performance model on which the job has an influence, guidelines which a direct impact on the job) :


EDF Luminus' IT organization should accelerate its transition towards a more strategic business contribution role and step away from a predominating focus on the delivery of technology services.

IT within EDF Luminus needs to look forward on the next evolution, taking into account value, efficiency and effectiveness.



The priorities for IT

  • Create a strong shared vision on future I.T
  • Increase Business & IT alignment
  • Increase the financial efficiency / Affordable IT
  • Keep the excellence in the "Run" / delivery of technology services
  • Talent : Attract Retain, Foster & Nurture !


Framework & Boundaries - Main challenges and complexity elements  (for example main problems the job must deal with, main difficulties, obstacles, conflicts, risks job faces)

  • EDF Luminus is a major player in the utility market. This market is evolving from a commodity market to a service market, has seen the introduction of decentralized production, flexible resources and increased demands from regulators and TSO's. Both digitalization and innovate services are required on the level of the energy production, distribution and optimization departments. This makes our activity very challenging both on business and IT services.
  • To accommodate this fast changing world EDF Luminus IT has organized its delivery in a bimodal way where on the one hand changes are delivered directly by BizDevOps teams organized in Release Trains (i.e. the teams work according to a scaled Agile framework) and on the other hand through Big Projects which are managed by project managers.
  • The last years some important investments were done to standardize our IT platforms. Nevertheless we still have some IT debt coming from our EDFL history.
  • EDFL has a multi technological environment where besides applications also topics like infrastructure, database, security and impact on operations needs to be taken into account
  • The core applications used are SAP and in Retail and B2B area, Aligne in the Optimization & Risk area and SAP in the finance & HR area. Interconnection happens by an ESB/API Hybrid communication platform, reporting & analysis via a central BI foundation.
  • More specifically for this role, it's important to understand that the Optimization department has as mission to preserve at all times the balance of the gas and electricity portfolios to optimize the value of our assets while keeping the cost for our clients as low as possible
  • The optimization landscape is heavily changing with the introduction of decentralized production, flexible resources and increased demands from regulators and TSO's
  • The aim is to reduce operational business cost. We are in a face to replace legacy applications by new COTS applications. This will require complex integration to existing landscape and also includes the implementation of a new Operational Data Store and Data Management System. The current IT infrastructure, which is becoming obsolete, is a mixture of applications (homemade and COTS) and technologies (excel/access, .NET, Java, APEX, Delphi, VB6) and strong interfacing (DLL, Web services, ODBC, FTP, SFTP, file transfer).
