These files form the Valuing continuous electricity supply part of the ARCoES project. Files are the anonymised focus group transcripts, Choice Experiment (CE) attributes and levels for valuing continuous electricity supply, the Ngene coding using efficient design to generate a blocked CE design, the customer survey which contains the Willingness to Pay (WTP) CE scenarios and survey questions, and the anonymised participant responses to the survey. The responses were modelled using a mixed logit model. There is also a Table of previous WTP studies showing authors, attributes, levels and WTP estimates for a one hour power cut.
