Case Study Axpo





"With Expro iRIX enabled to increase both efficiency and quality. This allows us to concentrate better on our core competencies and exploit short-term power trading."

Roman von Siebenthal, Head Spot & Forward Trading, AXPO Solutions AG




Initial situation: Manual spot trading


Manual spot trading

Axpo carried out its spot transactions on the power exchange using Excel sheets. Each branch made its own additions, which were not merged. For the calculation of the exchange bid- data from various sources was obtained manually. This process was unstable and slow.


Goals of the new solution

  • Unified solution for all branches
  • Efficiency in the procurement of bidding data and quality improvement through automation of data sources
  • Central historicization of stock exchange bids and surcharges
  • Possibility of expansion for new stock exchanges



The solution: Exchange Professional


iRIX was commissioned to develop an application that support traders as an Excel plug-in. The data from individual Excel sheets as well as all master data for the configuration of the stock exchanges are stored centrally in the database. The server establishes communication between the data sources such as e-mails from customers and the position management system on the one hand and the Excel plug-in on the other, and handles all calculations. In Excel, the data can be updated at the push of a button.


The stock exchange bid is processed on the server. The aggregated data is presented in Excel and placed on the stock exchange. The stock exchange surcharge is read in centrally via Excel and passed on to the position management system. In addition, the stored data will be used as references and are available for audits.


An automated installation routine ensures that all traders always use the latest version. Further stock exchanges can be easily integrated.





Added value for the customer


risk minimization

Development and support are outsourced to iRIX, which can adapt the application to new requirements at any time and ensures smooth operation.



The know-how, which is distributed over several local Excel solutions, is centrally combined in one application and thus secured.


Increased efficiency and quality

Media breaks and dependencies were eliminated by stable automatic interfaces between the applications.

The application is designed for several exchanges which enables the customer to expand his field of activity and ensures efficient power trading.
