Privacy-relevant smart metering use cases

Privacy in Smart Metering has been discussed extensively, as have privacy enhancing technologies (PETs). However, neither of these items has been put into the perspective of the actual use cases at hand. This perspective is crucial to (i) map the correct PETs to each use case and to (ii) identify gaps, i.e., use cases which are privacy-relevant, but not yet covered by a PET. Beside the construction of such a set of privacy-relevant smart metering use cases, some open research questions have been found. Most importantly, the Smart Metering systems must be described in more detail in order to facilitate a sound development of PETs.
