The thirteenth IGU Wholesale Gas Price Survey, which began in 2005, shows the trend towards gas-on-gas competition (GOG) in the global gas markets, continued in 2020. In the 2020 survey responses were received for 94 out of 113 markets, but these responses covered 98% of total world consumption. The share of GOG rose by 1 percentage point in 2020 from 2019 to reach 49.3%. GOG gained share against OPE, while there was a switch to OPE away from regulated pricing in some countries, leaving the OPE share unchanged at around 18.5%. The rise in GOG was largely driven by a significant shift in LNG imports to GOG and away from OPE. The rise in GOG LNG imports in 2020, reflected another sharp rise in spot LNG cargoes.
