Costs relating to items that are consumed in the manufacturing process, including changes in inventories and distribution costs up to the point of sale.

Included in materials, energy and consumables used is carbon taxes of R1,4 billion (2023 - R1,7 billion; 2022 - R1,2 billion). Under the carbon tax regulations, South African companies are able to buy carbon credits from third parties to offset a portion of their carbon tax liability. To this end, Sasol enters into strategic and cost-effective long term agreements with reputable suppliers for credible high-quality carbon offset credits. The ultimate amount of credits acquired will depend on the development of projects under the applicable standards, delivering the credits within the agreed timeframe, and will be subject to audit/verification by an independent party.

Purchase commitments

The Group enters into off-take agreements as part of its normal operations which have minimum volume requirements (i.e. take or pay contracts). These purchase commitments consist primarily of agreements for procuring raw materials such as coal, gas and electricity.

The most significant commitment relates to minimum off-take oxygen supply agreements for Secunda Operations of approximately R211 billion (2023: R219 billion).

●

The Oxygen Train 17 oxygen supply agreement runs to 2037, with an option to renew the contract to 2050. The renewal option is not taken into account in the calculation of the commitments.

●

The Oxygen Trains 1 – 16 arrangement is managed through various agreements, including the Gas Sales Agreement, Utilities Agreement and a suite of other contracts. In terms of the Utilities Agreement, Sasol is contractually bound to buy oxygen and other derivative gasses from Air Liquide annually, while Air Liquide is bound to buy utilities from Sasol for the same amount for 15 years. The ultimate amount of the commitment is dependent on expected future increases in the regulated price of electricity in South Africa and is presented on an undiscounted basis.

Additionally, Sasol South Africa Limited (SSA), together with Air Liquide Large Industries South Africa Proprietary Limited (ALLISA), signed six Power Purchase Agreements (PPAs) to date, with contractual terms of 20 years each, for the procurement of more than 600 MW of renewable energy from Independent Power Producers. The joint procurement of renewable energy by SSA and ALLISA is primarily aimed at the decarbonisation of the SO site.

Four of the six projects reached financial close during the 2024 financial year. Subject to financial and grid connection approvals, the remaining two projects are expected to reach financial close in the 2025 financial year. Projects are expected to reach commercial operations between 2025 and 2026.

SSA also signed a 20 year PPA with Msenge Emoyeni Wind Farm Proprietary Limited, for the procurement of 69 MW of wind capacity from the Msenge project, located in the Eastern Cape. The project reached financial close in March 2023, and commercial operation is targeted for financial year 2025.

Furthermore, Sasol is party to long-term gas purchase agreements of approximately R32 billion (2023: R38 billion) which commits Sasol Gas (Pty) Ltd (Sasol Gas) to purchase a minimum quantity of gas until 2034.

Contractual purchase commitments are taken into account in testing the recoverability of the carrying amounts of property, plant and equipment. At 30 June 2024 and 30 June 2023, there were no onerous contracts relating to these off-take commitments.
