South African energy regulator approves Sasol Gas maximum gas price adjustment for Q2 FY2025/26

The National Energy Regulator of South Africa (NERSA) said in a statement on September 9 it had considered and noted Sasol Gas Limited’s (Sasol Gas) adjustment of its maximum gas price for the second quarter (Q2) of the 2025/26 financial year (FY2025/26).

In its June 30 ruling, the regulator allowed Sasol Gas, a wholly-owned subsidiary of Sasol South Africa Limited (SSAL), to adjust its maximum gas price quarterly, based on acquisition costs and pricing data submitted to NERSA. On August 15, the company submitted information for the October–December 2025 quarter.

NERSA said it had verified the figures against contracts, tested their accuracy, and confirmed volumes with data from Mozambique. As a result, Sasol Gas’s maximum gas price for Q2 of FY2025/26 has risen by 4% compared with the previous quarter, from ZAR87.04/GJ ($4.79/GJ) per annum to ZAR90.57/GJ ($4.98/GJ).

The increase is mainly owing to higher costs of new Mozambican gas, influenced by oil-linked derivatives, currency shifts, and changes in the US Producer Price Index (USPPI).

“For clarity, NERSA would like to emphasise that the extent of adjustment does not necessarily translate into the same amount of adjustment on actual gas prices Sasol Gas charges to its customers,” said Nomfundo Maseti, full-time regulator member primarily responsible for piped-gas regulation. “It is expected of Sasol Gas to charge actual gas prices lower than the maximum price,” she added, as per NERSA’s statement.

According to the regulator, the quarterly monitoring system protects consumers by keeping prices fair, holds licensees accountable by requiring proof of cost changes and improves transparency through NERSA’s regular review of gas costs and price adjustments.
