Abstract [en]

In the next five to ten years, the electricity market is facing a number of challenging changes. This study has taken a closer look on a portion of these and some of their likely consequences. In summary, the changes are either related to an increase in frequency at which meter readings are collected or to the expansion of the electricity market to cover the whole Nordic. The goal has been to investigate what is on the horizon from an IT perspective in terms of performance and security requirements that Vattenfall needs to prepare for. Requirements related to these quality attributes are extra important for companies in the utility business as the amounts of data being managed are very big and because of the private nature of the information.

The main source for elicitation of data has been interviews. In order to elicit as many requirements as possible, stakeholders with diverging backgrounds from different departments at Vattenfall have been interviewed. The performance results are presented and analyzed using ArchiMate and Quantitative analysis. The corresponding method used for the security risks is CORAS. The performance analysis technique was also used to create models of the current system situation, in order to make it easier to perform a comparison. In conclusion, the results show that Vattenfall will have to implement big improvements for certain parts of its IT in order to cope with future market changes.
