Literature survey and comparison of consumer interruption costs in North America and Europe

A survey on the assessment of electricity consumer interruption costs (CIC) from published literature in North America and Europe was conducted to identify the different approaches adopted by various countries and to make key observations including whether there is any international norm in such CIC assessment. As customer survey was found out to be the de facto approach adopted by utilities in USA and Canada to assess CIC, a further literature search was conducted to ascertain the past practices of CIC customer surveys conducted in these two countries. Finally an attempt was made to compare the CIC in different countries and the results are presented with discussions.
