The Renewable Energy and the Smart Grid (NZ GREEN Grid) project’s Household Electricity Demand Study data includes:
This data has been cleaned and anonymised using the code in this R package to produce the ‘safe’ dataset available from the UK Data Service. None of the data is held in the R package so none of the code here will work unless you also have access to the data.
Accessing the data
The data is archived as:
- Anderson, Ben and Eyers, David and Ford, Rebecca and Giraldo Ocampo, Diana and Peniamina, Rana and Stephenson, Janet and Suomalainen, Kiti and Wilcocks, Lara and Jack, Michael (2018). New Zealand GREEN Grid household electricity demand study 2014-2018. [Data Collection]. Colchester, Essex: UK Data Service. DOI: 10.5255/UKDA-SN-853334
You will need to register for a (free) UK Data Service account before you can download the data. Staff at UK universities should be able to use their institutional login to do so. Users from outside the UK will need to use a specific form to request a UK Data Service user id. Once registered & logged in you should be able to download the data.
Please document any errors, problems or queries by raising a github issue and we will try to respond.
This is not open access data. It is licensed as Safeguarded data under the UK Data Archive End User Licence conditions. You will need to agree to these T&Cs before downloading the data.
We also encourage you to log your (intended) data usage via https://github.com/CfSOtago/GREENGridData/issues/38. This is not a requirement of re-use but it helps us to justify both continuing to improve the data and also releasing future datasets.
Version 1 - September 2018
Version 1 of the data archive includes:
- powerData.zip: 1 minute power demand data for each circuit in each household. One file per household;
- ggHouseholdAttributesSafe.csv.zip: anonymised household attribute data;
- simple line charts of mean power per month per year for each circuit monitored for each household. These are a useful check;
- tile plots (heat maps/carpet plots) of the number of observations per hour per day. Also a useful check…
- PDF snapshots of the live documentation found below.
NB: Version 1 of the data package does not include any time-use diary data.
Accessing and using the R code
The GREEN Grid Data R Package can be forked, cloned or installed as an R package. Amongst other things it contains the following folders:
- reshareDataProcessing - R/Rmd script examples to show how the clean anonymised data can be analysed.
- originalDataProcessing - R scripts to process data and generate data quality reports. These will not run without access to the original study data but you can review them to understand why the anonymised data looks the way it does;
- docs - the data archive documentation published via the github pages that you are now reading. These were created sing the code in the originalDataProcessing folder.
We encourage feedback and contributions but inevitably #YMMV.
We also encourage you to log your (intended) data usage via https://github.com/CfSOtago/GREENGridData/issues/38.
