citiworks AG, a leading German energy trading and services company, has chosen Previse Systems as its partner for its future ETRM platform.

citiworks AG had initiated an EU-wide multi-stage tendering process for new ETRM software to replace its existing system with a modern, cloud-native SaaS solution that ensures high performance, particularly for real-time risk and position evaluations. The new system needed to meet citiworks AG’ functional requirements while offering the flexibility to quickly adapt to future changes. Additionally, seamless integration into citiworks AG’s IT ecosystem was crucial to maintaining a robust, modular architecture, ensuring a future-proof and adaptable infrastructure capable of responding efficiently to evolving market and regulatory demands.

citiworks AG chose Previse Systems for its next-generation ETRM solution. Previse Coral’s state-of-the-art architecture and serverless technology ensures high performance and scalability without infrastructure overhead. The open Coral Ecosystem framework ensures seamless integration into citiworks AG’s IT landscape while enabling flexible functional extensibility to accommodate future business needs, while Master Data as a Service simplifies data management and reduces costs. This combination of cutting-edge technology and adaptability made Previse Systems the ideal choice for citiworks’ evolving requirements.

The implementation will cover the entire scope of commodities traded by citiworks and is set to be delivered by the end of Q1 2026.

“In our search for a modern, high-performance ETRM system that can map our sometimes very complex processes and at the same time offers the flexibility to react quickly and efficiently to future changes and requirements, we opted for Previse Coral. We are convinced that with Previse Systems we have not only chosen the best professional and technological solution but have also found a reliable partner with whom we can look to the future with optimism”. 

The new system will enable us to further automate our processes and expand citiworks’ strong position in the areas of flexibility marketing, PPA and real-time trading, as well as ensuring the continuous improvement of our technological capabilities in the future.”

Markus Nagel, IT Project-Steering at citiworks AG/ENTEGA AG

“We are delighted that citiworks has selected Previse Coral as their new ETRM solution. The evaluation process was characterized by efficient collaboration, which we now look forward to extending into the joint project ahead. We are confident that our combined efforts will lead to a successful implementation, and we look forward to a long-term partnership with citiworks, focused on growth and continued success.”
