Britain's smart meter programme: A case study in privacy by design

Following requirements in the 1996 EU Energy Efficiency Directive, member states are developing programmes to encourage the installation of ‘smart’ power meters that record much larger quantities of data about power usage than traditional meters. These data can reveal a great deal of information about individual household activity, leading privacy regulators to call for privacy to be ‘designed in’ to these systems. The British smart metering programme has given some attention to this privacy by design process. This article assesses its effectiveness in this case, using documentary analysis, participant observation, and follow-up interviews with a range of stakeholders. It finds that decisions made early in the British programme had negative privacy impacts that have only been partially remedied by the later development of detailed rules on the processing of smart meter data by energy suppliers and distributors. The article also considers broader lessons for the privacy by design approach.
