101 companies blacklisted in South Africa
Eskom has banned 101 suppliers from doing business with the power utility for periods of up to 10 years.
This follows Eskom’s efforts to step up efforts to tackle fraud, corruption and other forms of misconduct across its supply chain.
The restrictions were imposed through Eskom’s supplier disciplinary process between February 2023 and 31 March 2026.
They relate to cases dating from 2015 to March 2026, although most of the cases arose between 2016 and 2022.
The restrictions were considered by Eskom’s Supplier Review Committee, which assessed allegations of supplier misconduct and determined appropriate sanctions based on the available evidence, applicable policies and governance requirements.
The process can result in restrictions of up to 10 years, depending on the seriousness of the misconduct.
Eskom Group Chief Executive Dan Marokane said the utility was focused on making sure that misconduct resulted in meaningful consequences.
“Fraud, corruption, procurement irregularities and supplier misconduct have affected public confidence and highlighted the need for decisive, transparent and sustainable consequence management across Eskom’s supply chain,” said Marokane.
He said Eskom now aims to process and resolve newly referred supplier disciplinary cases within 90 days.
“The progress achieved to date demonstrates Eskom’s determination to confront fraud and corruption in a practical and measurable way,” he said.
Marokane added that reducing backlogs and resolving new cases more quickly would help ensure that supplier misconduct was dealt with fairly while reinforcing accountability.
The announcement follows allegations by the Association of Private Security Owners (TAPSOSA) regarding 26 black-owned companies that were among the 101 suppliers restricted by Eskom.
TAPSOSA had alleged that the companies were referred to the National Treasury without due process. Eskom rejected this claim, and said the referrals followed its internal supplier discipline and governance procedures.
Eskom said all affected suppliers were given an opportunity to respond to the allegations before decisions were made.
More cases are being prepared for referral to the National Treasury
The utility said the cases involved serious misconduct, including fraud, corruption, misrepresentation, collusion and other integrity-related breaches.
It also rejected suggestions that suppliers were referred because of ordinary contractual or operational problems, such as isolated failures to meet service-level agreements.
Eskom further denied claims that the companies were targeted because they had acted as whistleblowers.
It said TAPSOSA was not a party to the supplier disciplinary proceedings involving the 26 companies and questioned the basis on which the organisation claimed to represent them.
Of the 53 referrals Eskom made to National Treasury for supplier restrictions, only one involved a company providing security-related services, the utility said.
The disciplinary process forms part of Eskom’s broader efforts to strengthen procurement governance.
It is aligned with National Treasury’s Public Finance Management Act (PFMA) Supply Chain Management Instruction No. 3 of 2021/22, which provides a framework for dealing with supplier misconduct.
Eskom’s Supplier Integrity Pact also requires suppliers to maintain ethical standards and refrain from dishonest, fraudulent, corrupt or anti-competitive conduct throughout the procurement process.
As of 20 August 2026, the National Treasury had recorded 35 companies and 45 directors or owners linked to Eskom’s supplier disciplinary process on its restricted supplier database.
Being listed means the affected suppliers are restricted from doing business with the state for the applicable restriction period.
This extends the consequences of misconduct beyond Eskom to other areas of government procurement. Eskom said additional cases were being prepared for referral to the National Treasury.
