Industrial, commercial, and domestic customers in South Africa use natural gas as an alternative source of energy to electricity. Sasol Gas – which sources natural gas from the Pande and Temane gas fields in Mozambique – is the only supplier of natural piped gas in the South Africa, selling to gas traders and end-users in the country through a network of transmission and distribution pipelines.
This prosecution stems from three complaints lodged against Sasol Gas last year by Egoli Gas, the Industrial Gas Users Association of South Africa , and Spring Lights Gas. "This information consists of the gas landing cost information that Sasol Gas provides to the United States Securities and Exchange Commission each financial year and information recorded by the South African Revenue Service in its Trade Statistics Data, reflecting the value and volume of natural gas imports from Mozambique."
