Modernising the ETRM System as a Building Block of a Future-Proof Trading Strategy

The energy market is undergoing profound change. Increasing volatility, the growing relevance of short-term trading products, and rising requirements for automation, system integration and data availability are presenting market participants with significant challenges.
To remain a high-performing and innovative partner for its customers in energy trading going forward, SWU Energie GmbH has decided to replace its existing ETRM system with a new, future-proof solution.
As part of the selection process, various systems were evaluated and a range of new, innovative solution approaches assessed. In this context, the solution offered by Previse Systems AG proved convincing both technologically and functionally.
With Previse Coral, SWU Energie GmbH is adopting a cloud-native platform that provides integrated coverage of the entire deal lifecycle in energy trading and can be flexibly integrated into existing IT landscapes. The solution supports a high degree of automation, offers a central data foundation for market, portfolio and risk information, and enables transparent management of trading activities across all relevant commodities. This creates the conditions for SWU Energie GmbH to respond more quickly to changing market conditions, increase process efficiency and sustainably manage the growing complexity of energy trading.
The open and flexible system architecture allows for efficient integration into our existing IT landscape while at the same time providing a solid foundation for future extensions. In particular, the ability to process large volumes of data in real time and present them in a consolidated manner within a single system interface will provide long-term support, especially in the area of direct marketing. We are confident that we have found an innovative and reliable partner in Previse for the continued development of our energy trading activities and we look forward to a successful collaboration.

Municipal utilities are more directly exposed to market forces than ever before – from volatile wholesale prices and increasing regulatory requirements to growing data and process complexity. To remain operational under these conditions, utilities need systems that reduce complexity rather than amplify it. Previse Coral is designed precisely for this purpose: a cloud-native ETRM platform that adapts to the specific requirements of municipal utilities – regardless of size or trading volume – and provides a transparent, scalable and future-proof foundation for procurement, portfolio management and risk management.
