The idea for a survey of wholesale gas price formation mechanisms arose at the beginning of the triennium leading to the 2009 World Gas Conference. The Strategy, Economics and Regulation Programme Committee (PGCB) had set up a new sub-group to consider gas pricing, with a key remit to carry out a comprehensive analysis of gas price formation mechanisms. The sub-group decided to carry out a survey of current pricing mechanisms around the world, not only for gas traded internationally, but also for gas produced and consumed within countries. IGU members were surveyed and provided the data and the survey responses were collated and analysed by Nexant. The 2009 World Gas Conference in Buenos Aires presented the results of the surveys for the years 2005 and 2007. Two further surveys for the years 2009 and 2010 were undertaken and presented at the 2012 World Gas Conference in Kuala Lumpur. This 2014 survey is the third survey undertaken in preparation for the 2015 World Gas Conference in Paris5, following on from the 2012 and 2013 surveys, and is the seventh overall. In the 2014 survey responses were received for some 71 out of 109 countries. Data on the remaining countries, where responses were not received, was researched by Nexant. However, the 71 countries where responses were received covered 94% of total world consumption.
