Changes in electricity systems mean that more detailed information about demand levels for particular energy services in the home are now available to energy researchers. Accordingly, it is useful to determine how these data might be best used by energy researchers. To advance this discussion, 13 studies that use intrusive load-monitoring techniques to generate, to present, and to make effective use of, disaggregated end-use electricity data from households are identified. These studies are placed within a broader literature context (including studies using non-intrusive load-monitoring techniques), are summarized briefly, and are cross-compared in order to delineate emerging issues. These issues are as follows: methodological challenges, including monitoring equipment performance and participant recruitment; ways to present the time-and space-specific nature of the end-use electricity data generated; advances with respect to end-use electricity models that can be built; appliance-specific insights; and future priorities for this kind of work, including energy conservation insights, relevant policy recommendations, and priority academic investigations. Finally, reflection upon these 13 studies, as well as the broader energy research agenda, generates a number of priority areas for work going forward: making effective use of additional data; broadening the focus to include electricity production and storage, as well as other energy, carbon, resource, and information flows; placing these data within broader social contexts and wider power system considerations; and encouraging effective use of these data to advance energy system sustainability, at both the household and community levels. of advanced sub-metering technologies (e.g., smart electrical panels and smart plugs) has facilitated the collection of more electricity end-use information. With this detailed information now more readily available (e.g., how much electricity was used by a refrigerator at different times of the day in a particular household), a whole new set of energy research questions can be investigated.The purpose of this article is to determine the impact of the availability of disaggregated (divided according to time-of-use) end-use electricity information from households upon energy research. The investigation unfolds in four parts. First, the area of study is elaborated both by identifying our focus as well as other contiguous areas of research-together, this forms the broader context. Second, key research articles that use fine-resolution (i.e., high frequency), disaggregated end-use electricity data in households are identified and briefly summarized. Third, these articles are compared with each other in order to delineate emerging themes. Fourth, reflection upon these themes and the potential to address policy debates is undertaken in order to sketch an agenda for energy researchers going forward. It is critical that recent advances in information and communication technologies (which enable the collection of these data) are accompanied...
