Eskom boosts cybersecurity after breach exposed flaws in prepaid token system
In December 2024, the power utility disclosed, as part of its full-year 2024 financial results, a forensic report detailing the breach of its Online Vending System (OVS).
'The system was exploited to generate and distribute fraudulent prepaid electricity tokens, revealing critical vulnerabilities in both the physical and cybersecurity components of the utility's prepaid electricity infrastructure.
'In response, Eskom undertook a comprehensive review and intervention strategy aimed at mitigating these vulnerabilities and restoring system integrity,' Eskom said in a statement.
Eskom Chief Technology and Information Officer Len De Villiers says the power utility has 'successfully strengthened the protection of its current systems against potential threats'.
'All system enhancements are managed through a robust change management process that spans all divisions, ensuring consistent oversight and control. These measures are part of Eskom's ongoing commitment to safeguarding operations and addressing identified vulnerabilities,' De Villiers says.
The latest key actions implemented include:
Internal controls to deal with electricity theft have been implemented
Measures to safeguard the system by reinforcing physical infrastructure and limiting both physical and digital access
Enhanced monitoring capabilities to ensure transparency and timely reporting
Ongoing collaboration with law enforcement agencies to support investigations and ensure accountability. As part of this process, internal employees who have been implicated have been placed on precautionary suspension pending further review
Augmented in-house capabilities, supported by an external information technology firm tasked to better manage risks and safeguard operations
Co-ordinated system upgrades through a structured change management process
Regular reporting to the Eskom Board, which has maintained oversight throughout the remediation process
Accelerated acquisition of a new, secure vending system, designed to replace the current OVS and prevent future incidents.
Eskom Group Chief Executive Dan Marokane said: 'We are fully aware of the challenges that have emerged within the OVS environment, and we have taken clear steps to address them.
'Our focus is on restoring trust, strengthening our systems, and ensuring that our customers can rely on a secure and efficient service. This is not just a technical fix, it is part of a broader commitment to transparency, operational excellence and accountability.'
Eskom, in conjunction with law enforcement, is investigating, with the findings to be disclosed once complete. – SAnews.gov.za

Gridlock: The urgent imperative to increase SA's transmission capacity
South Africa is not short on ambition or potential when it comes to energy reform. The country's renewable energy market is maturing. Investment appetite is increasing and policy shifts, like the recent Electricity Regulation Act, indicate focused commitment to achieving a more competitive, sustainable and competitive energy market. However, one obstacle remains a hindrance to this momentum - transmission. Despite billions of rand committed to generation, over 20GW of renewable energy remains untapped due to a lack of grid capacity. As the country scrambles to meet rising energy demand and decarbonise its economy, transmission has emerged as the single most critical enabler of energy security and low-carbon growth. Importantly, the lack of transmission is not just a technical hurdle. It is the vital lever that is needed to unlock real energy transformation. With open access to the grid, more independent power producers (IPPs) will be able to participate and, more importantly, the increased capacity created by a robust transmission ecosystem will mean that South Africa (SA) can unleash the full potential of renewables – cutting emissions while improving reliability. The good news is that we appear to finally be on the path towards this enhanced transmission capacity. The establishment of the National Transmission Company of South Africa (NTCSA), to be spun off from Eskom, was a significant early milestone on this journey. This unbundling will enable open and transparent access to the grid for public and private generators. It will also pave the way for the trading of electricity through market platforms and wheeling arrangements, creating the foundation for a more dynamic and competitive power sector. The NTCSA coupled with the proposed Independent Transmission Projects (ITP) programme, creates a compelling case for private sector participation, not just in generation but also in grid infrastructure. However, there is still a long road ahead. The Transmission Development Plan (TDP) 2024 identifies the ambitious objective of integrating around 56GW of new generation and constructing over 14 000km of transmission lines by 2034. That is less than 10 years from now. The initial phase to 2029 targets a more realistic 5 043km of powerlines, but with only 286km expected to be completed in 2025, the gap between ambition and delivery remains immense. Also, with Eskom's financial constraints and national debt levels limiting national government's capacity to finance these builds, the success of the ITP programme will depend heavily on attracting private sector buy in, partnership and investment. Private investment in these ITP projects will require clear revenue models, predictable tariff structures and credible counterparties. The private sector needs certainty, not just around returns, but also when it comes to things like termination and non-payment recourse. South Africa could apply lessons from past public-private partnerships, like the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP). A stable, predictable, and transparent regulatory environment, consistently applied, is key. Investors will need absolute certainty regarding tariff structures, off-take agreements with the NTCSA, and the long-term security of their substantial investments. The government's commitment to late-stage tendering – ensuring environmental approvals and servitudes are largely in place before bids – is a sensible move to de-risk projects. Standard Bank is actively engaged in this sector, working to structure bankable transmission models. There are multiple avenues to de-risk transmission investments, and we can leverage global lessons and precedents to achieve this. Countries like Brazil and Peru have successfully deployed BOOT (Build, Own, Operate, Transfer) models to deliver thousands of kilometres of grid infrastructure. We do not see any reason why South Africa cannot do the same. Transmission infrastructure does not have to be the bottleneck; it is an enabler of energy reform. But to do that, it needs to become a national investment priority. There are encouraging signs that this may be the case. The Request for Information (RFI) that took place between December 2024 and February 2025 gathered insights from market participants on how to accelerate the development of transmission infrastructure. Further milestones include the imminent release of the full Request for Proposal (RFP), which will signal a vital shift from talking and planning to execution, and allow government to shape the legal frameworks, procurement mechanisms and support instruments that will guide the first batch of independent transmission projects to market. This is the crucial next step in shifting SA's energy reality from crisis management to long-term and sustainable resilience. DM

Nobuhle Nkabane stands firm against opposition criticism of higher education budget
Higher Education Minister Nobuhle Nkabane says she will not dignify direct attacks at her other than focus on the task at hand of serving the people of South Africa. Image: Facebook Higher Education Minister Nobuhle Nkabane on Thursday said she would not dignify the attacks levelled against her when the DA and some opposition parties rejected her department's budget. Nkabane presented her department's budget for the 2025/26 financial year in the National Assembly two days after doing so in the National Council of Provinces, where the DA, MK Party, and the EFF rejected it. The department has been allocated R142.4 billion and is set to increase at an average annual rate of 4.4% to R150 billion in the next financial year and R158 billion in 2027/28. 'This growth is not sufficient to meet growing demands for additional resources,' she said. Video Player is loading.

Advertisement Next Stay Close ✕ The Technical and Vocational Education and Training colleges have been allocated R14 billion, and both the Sector Education and Training Authorities and the National Skills Fund have a combined R26 billion. The National Student Financial Aid Scheme (NSFAS) is allocated R48.7 billion, and its allocation will increase to R51 billion next year and R53.4 billion in 2027. Nkabane said the allocation was not sufficient to meet the growing demand for access to higher education. 'We continue to seek efficient ways of allocating limited resources to ensure that no deserving learner is left behind.' She also said NSFAS remained committed to implementing a comprehensive student funding model for higher education to address the needs of the 'missing middle'. 'The National Skills Fund has set aside R3 billion over a three-year period.' Nkabane said the allocation for university education increased from R91.7 billion to R96 billion, with a R1.4 billion deficit on the universities' budget. 'We continue to work with National Treasury to find a sustainable adjustment to the universities' budget,' she said. Tebogo Letsie, ANC MP and chairperson of the Higher Education Portfolio Committee, said they would ensure that the department, NSFAS, and universities were accountable. 'We will ensure public resources are used efficiently, effectively, and transparently to deliver the ANC vision,' he said. Letsie took a swipe at the DA for its stance to reject the department's budget because they don't believe Nkabane should be the minister. 'When you vote in 2026, remember them, they will be saying your poor child must not go to school and university because they have a problem with the minister,' he added. MK Party MP Mnqobi Msezane said they rejected the budget because they don't have confidence in the Ministry and Director-General Nkosinathi Sishi, who they claimed faced allegations of gross misconduct, fraud, and corruption, and was not suspended or investigated by Nkabane. 'We don't have confidence in the Ministry and the department to oversee this budget,' Msezane said. DA MP Matlhodi Maseko said the higher education system was being systematically eroded by incompetence, deception, and the unchecked abuse of power in the system. 'The minister has repeatedly given conflicting representations to this House,' she said in reference to the SETA boards' chairperson appointment scandal and listed other challenges in the department under Nkabane's watch. Maseko said President Cyril Ramaphosa should remove Nkabane without delay. 'The future of our youth depends on strong, ethical, caring leadership, and until there is accountability at the very top, every rand in this budget will be another drop in a leaking bucket,' she said. EFF's Sihle Lonzi accused the DA of cherry picking which budget to support and also criticised it for discovering corruption in the department after former deputy minister Andrew Whitfield was fired from the executive. However, Lonzi said his party would not support the budget after presenting a seven-point plan to rescue the department. 'We have no certainty that the R142 billion is going to be used correctly,' he said.
