Modernization of Energy Market Communication: innogy Gains a Secure and Scalable Cloud Solution on SAP BTP

For innogy Česká republika, we replaced an end-of-life solution on SAP NetWeaver with a modern cloud architecture. The new system for data exchange with market operator OTE, the EDC data center, and distribution partners reliably processes over 2.5 million messages per month—with peak loads reaching 60,000 messages per hour—delivered flexibly, securely, and with zero operational disruption.

From Legacy NetWeaver Solution to Modern Cloud BTP Application and AI Readiness

The original custom solution for market communication was hitting the limits of the aging SAP NetWeaver platform, burdened by high maintenance demands for custom legacy code and limited scalability. Together with the innogy team, we chose a more strategic approach: rather than merely replacing an old application, we leveraged the SAP Business Technology Platform (SAP BTP) to build a robust ecosystem ready for the future expansion of enterprise cloud solutions.

The newly deployed Utilities Market Communication (UMC) solution connects custom business logic in the SAP BTP ABAP Environment with the robust capabilities of SAP Integration Suite. The delivery includes a dedicated data model, communication configuration, an intuitive Fiori cockpit for real-time operational monitoring, and automated reprocessing mechanisms for failed messages.

All custom development is kept strictly outside the SAP S/4HANA Private Cloud ERP core, keeping it standardized and protected against unwanted modifications. The migration to the new architecture was completed gradually and in a controlled manner during full production in just six months, without disrupting downstream business processes.

Key Project Benefits:

• Direct TCO Reduction: Decommissioning both the legacy application and the entire SAP NetWeaver environment delivered immediate operational savings and streamlined system administration.
• Dynamic Scalability: The cloud infrastructure instantly and elastically adjusts computing capacity to handle unpredictable market traffic spikes of up to 60,000 messages per hour.
• Clean Core by Design Architecture: Strictly decoupling custom modifications from the core ERP eliminates technical debt and significantly reduces the cost and complexity of future upgrades.
• A Foundation for Innovation and Business AI: Established enterprise governance, security policies, and unified monitoring clear the way for rapid deployment of future applications, intelligent process automation, and adoption of SAP Business AI.
