The Australian government's Department of Industry has a dataset on 31 example homes in 30 minute intervals on their open data site:
University of Massachusetts Amherst also has a research dataset:
The Australian government has published a Smart-Grid Smart-City Customer Trial Data.
There are two datasets (with additional bits and pieces - see below):
This data is from the customer trial conducted as part of the Smart Grid Smart City (SGSC) project (2010-2014). It provides one of the few linked sets of customer time of use (half hour increments) and demographic data for Australia, as well as detailed information on appliance use, climate, retail and distributor product offers, and other related factors. The project was jointly funded by the Australian Government and an industry consortia, led by Ausgrid. Data resources that comprise this Customer Trial Data may be linked by the Customer ID number. Details of data resources for this dataset are listed below and include: electricity use interval readings; customer household data; home area network plug readings; peak events; peak events response; and offer and acceptance.
The Almanac of Minutely Power dataset Version 2 captures three major types of energy consumption, namely electricity, water, and gas.
The data were captured in a Canadian residential home over a 2-year period (1 minute intervals). Also, it has been beautifully cleaned and ready to be analyzed.
