The NZ GREEN Grid household electricity demand study recruited a sample of c 40 households in each of two regions of New Zealand (Stephenson et al. 2017). The first sample was recruited in early 2014 and the second in early 2015. Research data includes:
The data collection was supported by the New Zealand Ministry of Business, Innovation and Employment (MBIE) through the Renewable Energy and the Smart Grid (GREEN Grid) grant (Contract ID: UOCX1203).
Whilst the GREEN Grid project collected data from 2014-01-06 to 2018-08-01, we do not have complete multi-year coverage of the 45 dwellings for whom data exists.
As Figure 4.1 shows data is available for most of the 24 dwellings in the Taranaki region from mid 2014 and for most of the 20 dwellings in Hawkes Bay from early 2015. In most cases the ‘right’ number of observations were received per half hour (30) when the dwellings were sending data. However not all dwellings sent data continuously with substantial attrition by 2017 (Figure 4.2).
