Use Case: IT Integration as a Key Success Driver in the Merger of Regional Energy Suppliers to Form E.ON Thüringer Energie AG

Optimization of processes and systems for sustainable growth

The success of the E.ON Thüringer Energie AG (ETE) merger was largely based on the seamless integration of IT systems. By harmonizing and consolidating the underlying processes and supporting IT infrastructure, the company aimed to unlock synergies and realize operational efficiencies. This involved a comprehensive analysis of the existing system landscape, followed by the initiation of IT integration projects. With a focus on leading systems such as SAP IS-U for billing and SAP PM for asset management, the IT aspect played a crucial role in optimizing operations and creating a unified energy landscape.

Overcoming challenges through expertise and collaboration

The IT integration process faced numerous challenges, particularly in the SAP IS-U environment, due to the simultaneous implementation of new regulatory requirements from the German Federal Network Agency.

  • Fast and consistent integration and harmonization of the underlying processes and supporting IT systems
  • Planning, managing and executing the integration and consolidation without interrupting ongoing operations
  • Adherence to internal quality standards, project management methods and compliance with the Sarbanes-Oxley Act
  • Ensuring a smooth transition and collaboration between knowledge workers from both predecessor companies
  • Selecting and supporting appropriate individuals for leadership positions in the projects
  • Managing the simultaneous implementation of new regulatory requirements of the Federal Network Agency, especially in the SAP IS-U environment
  • Coordinating and aligning multiple projects with varying goals and timelines
    Maintained a collaborative atmosphere and fostered a common understanding among all stakeholders
  • Successful integration of legacy GVT applications into the E.ON Corporate Network
    Establish integration contracts and service level agreements with E.ON’s corporate IT service provider, E.ON IS
  • Managing the commercial transition of the systems
  • Ensuring compliance with quality standards and the Sarbanes-Oxley Act in all projects

However, these challenges were effectively overcome through close collaboration between mgm consulting partners, the CIO department, the business departments and IT service providers. Regular meetings of the project managers fostered communication, alignment and coordination among all parties and ensured a common understanding of project statuses and next steps. With careful project management, the team successfully overcame obstacles and maintained a collaborative atmosphere.

Achieving homogeneity and continued growth

The coordinated efforts and disciplined approach to IT integration resulted in the achievement of key milestones. The relocation and complete transition of legacy GVT applications to the E.ON Corporate Network was also successfully completed. The result was a homogeneous process landscape that meets the stringent requirements of the German Federal Network Agency and sets standards within the E.ON Group. The reorganized and expanded CIO department will work with the business departments to further develop the integrated IT infrastructure, promoting continuous growth and innovation throughout the organization.
