Abstract
This report uses the full New Zealand GREEN Grid household electricity demand study research data to test the feasibility of multi-year data analysis beyond the single year made possible by the public available data (Stephenson et al. 2017); impute total dwelling load (W) per minute using the original circuit level data; produce a smaller mean half-hourly power demand (W) per circuit (and total load) per dwelling dataset for further analysis and extract half-hourly data for specified circuits.
