The Company Rankings reflect the Top 50 Companies for each natural gas consuming sector (Residential, Commercial, Industrial and Electric Generation) as well as for the total overall for all sectors, based on sales volumes, sales revenues and sales customers.
The data for these reports are taken from the companies' Annual Report of Gas Operations (ARGO). Companies are given the option of reporting their ARGO at the corporate level or at the subsidiary level. No effort is made to combine subsidiaries into corporate level data for the purpose of these rankings. If you would like similar data at the corporate level, please contact Paul Pierson, Manager - Statistics.
