Smart metering should be fully deployed before January 1st 2017 in Norway. The smart meters should be able to report consumption on a hourly basis, meaning that the amount of meter data will increase drastically. This raises some challenges with regards to sharing of meter data. The meter data has to be shared with the power producer, and the regulator has also stated that meter data also should be made available to third parties at the consumers wish. Meter data is important financial data and is also considered as sensitive data, and should be shared in a secure and reliable manner.This thesis gives an introduction to the smart metering technology, as well as the power industry in Norway. Further on, it presents some of the ICT solutions used in the industry today, as well as some proposed future solutions. Based on the proposed solutions and comments received from the industry actors, a test system with minimum centralization of business processes using Web Services technology has been developed. A solution based on the existing system, Nubix, is proposed. The system works as a forwarding hub, meaning that it forwards request from power producers and third parties to the grid owners. By using this solution the development costs can be kept low, and the system can easily be extended if more centralization of meter data and business processes is needed.
