(Reuters) -South Africa's logistics utility Transnet said on Thursday it would appeal a court decision to award Sasol and TotalEnergies about 6.2 billion rand ($344 million) in damages and interest to settle a tariff dispute.

Sasol said earlier on Thursday that it won the award in a High ruling against Transnet, which it accused of overcharging it for transporting crude oil for several years.

"The judgment thus has enormous implications not only for the public purse but also for Transnet's ability to discharge its obligations," Transnet said in a statement.

"Transnet intends to appeal the judgment," it added.

In 2017, Sasol Oil joined TotalEnergies, its joint venture partner in the Natref crude oil refinery, in a lawsuit against Transnet Pipelines over a tariff dispute.

"On 18 June 2024, judgement was handed down by the High

Court in Sasol Oil and TotalEnergies' favour. Damages in the amount of 3,889,475,802 rand plus interest amounting to approximately 2.3 billion rand ($128 million) were awarded to Sasol Oil," Sasol said in a statement.

TotalEnergies was not immediately available to comment.

The dispute has its roots in a 1967 agreement between the then South African government and Total, which established an inland crude oil refinery at a time when coastal refineries were struggling to meet inland demand.

To secure the participation of Total in the inland refinery Natref, the government put in place a pipeline tariff structure that would match the costs of a coastal processing facility.

Sasol, which was set up as a state-owned business in 1950 and privatised in 1979, owns 63,64% of Natref, with TotalEnergies holding the remainder.
