Customer Success.

When enercity was looking for a powerful low-code platform for its future IT strategy, it deliberately opted for a real-world stress test rather than a theoretical comparison. In 2023, the Commissioning Portal (IBA) was developed in collaboration with d.u.h.Group – a highly complex, production-ready core application for managing all meter movements within the network area. The success set the tone: Mendix was established as a group-wide platform and the foundation for a scalable multi-app architecture was laid.

In 2024, its capabilities became immediately apparent: with the Customer Self-Service (CSS) app, seven legally required click paths in accordance with Section 14a of the Energy Industry Act (EnWG) were digitally implemented within three weeks. At the same time, the vision of a central entry point took shape, leading to the launch of the enercity NetzPortal (eNP). PV Service and Digital House Connection went live in the same year.

A key driver was organisational commitment: enercity invested in its own Mendix team (Enablement & Scaling) as well as in dedicated roles such as project management and product owner for the eNP programme.

In 2025, the platform was further expanded to include, amongst other things, the sales partner portal (VPP), the district heating sales tool (FWV), the installer directory (IV 2.0) and services such as iMSys registration, PIN allocation and meter reading. The platform is not a completed project; it is continuously being developed and grows with every new solution.
