In the currently fast changing regulatory environment in the area of market communication (MACO) in the German energy sector, utilities are unable to keep track with these regulatory IT-requirements. Software-as-a-Service (SaaS) is a current trend in IT outsourcing, describing the use of standardized on-demand applications, which is associated with benefits such as faster deployment and access to expertise and risks, e.g. the threat of opportunistic behavior or security issues. A multiple case study has been conducted to assess the current adoption of SaaS in the area of MACO in the German energy sector and to identify the influences of different drivers. At the moment there are no solutions available on the market, thus no adoption of SaaS in this area has been observed. However the intention to use such applications when available has been stated.
