Cable Theft Crisis Escalates Across South African Infrastructure Networks

Cable theft continues to inflict substantial damage on South Africa’s critical infrastructure, affecting electricity supply, rail operations, telecommunications, and municipal services. State-owned enterprises including Eskom, Transnet, Telkom, and PRASA report ongoing incidents involving the removal of copper cables, leading to direct financial losses, replacement expenditures, and widespread service disruptions.

Transnet has documented significant cable losses on its rail network. In the 2023 financial year, 1,121 km of cable was stolen, representing a nearly eight-fold increase over five years. Between 2019/20 and recent years, more than 4,000 km to 4,600 km of copper cable was reported stolen from Transnet Freight Rail lines. In one week in April 2022, 123 attacks occurred on rail infrastructure, resulting in the theft of 39.4 km of copper cable. These incidents have contributed to revenue losses for Transnet, including R1.6 billion in one period and broader impacts on freight operations.

Eskom, which generates the majority of South Africa’s electricity, faces annual losses exceeding R2 billion from cable theft, with broader estimates for copper theft impacting the utility at R5-7 billion per year, plus approximately R2 billion for cable replacements. Vandalism and theft have led to power outages, transformer failures, and additional infrastructure damage. City Power in Johannesburg recorded around 2,000 incidents in one financial year, incurring R380 million in repair costs.

Telkom and PRASA have also reported substantial impacts. Combined direct losses for Telkom, Eskom, PRASA, and Transnet from cable theft and related vandalism are estimated at approximately R7 billion annually. The wider economic effects, including lost productivity, delayed services, and secondary costs, have been placed as high as R187 billion per year in some assessments. Overall copper theft damage to the economy has been estimated at more than R45 billion annually in independent research.

Gauteng Province alone recorded 5,914 cases of cable theft in power distribution networks since April 2019, accounting for nearly one-third of the national total of 19,919 cases reported in that period. Nationwide, municipalities experience an average of about 444 cable theft cases per quarter, with higher numbers often in January. Tshwane Metro Police Department logged approximately 1,498 incidents during the 2017/2018 period.

The theft primarily targets copper due to its value in the scrap metal market. Stolen cables are sold to illegal dealers, contributing to an illicit trade that supplies both domestic and international markets. Replacement costs are high: a metre of cable ranges from R1,000 to R1,400, with broader repairs for substations, transformers (R15-20 million for a 40 MVA unit), and joints (around R600,000 per 33 kV oil cable joint) adding significantly to expenses.

Service disruptions from cable theft affect multiple sectors. Power outages impact households, businesses, hospitals, and schools. Rail operations face delays and cancellations due to signal and power failures. Traffic lights become inoperable, causing road congestion and economic delays. Mining operations experience interruptions to machinery, conveyor systems, and ventilation, leading to production losses and additional security expenditures. Telecommunications services are disrupted, hindering connectivity.

Law enforcement has pursued numerous cases. Arrests occur regularly, including incidents involving foreign nationals and local suspects in possession of stolen copper. Convictions have resulted in lengthy sentences. Examples include a 15-year sentence for theft of Transnet cabling valued at R558,000; multiple 30-year sentences for tampering with infrastructure and cable theft; 20-year and 25-year terms in other cases; and group convictions such as 26 suspects for losses exceeding R29 million. In some periods, hundreds of arrests and dozens of convictions have been recorded in specific regions, with sentences totaling hundreds of years cumulatively.

Collaborative efforts among Eskom, Transnet, Telkom, PRASA, and law enforcement agencies, including the Hawks and SAPS, have focused on intelligence-driven operations, improved security, and prosecutions. Joint working groups have been established to address syndicates. Measures such as restrictions on scrap metal trading and enhanced site protection have been implemented or proposed. Despite these, incidents persist, with some reports noting temporary declines in specific metrics alongside continued high overall levels.

Cable theft remains concentrated in areas near informal settlements, industrial zones, and along transport corridors. Structures in these locations are frequently targeted, alongside farms and private properties. The crime involves organized elements, with evidence of insider involvement in certain cases and coordination among groups.

Statistics indicate more than 20,000 cases recorded countrywide in some annual periods. Earlier data showed increases, such as from 13,675 cases in 2003/04 to 33,156 in 2007/08 for related thefts. Transnet’s cable theft statistics reports are published monthly, tracking ongoing trends.

The cumulative effect includes billions in direct costs to utilities passed on through higher tariffs or taxpayer burdens, alongside indirect losses from reduced economic activity, investment deterrence, and service unreliability. Replacement and security spending diverts resources from maintenance and expansion of infrastructure networks.

This situation reflects a persistent challenge to South Africa’s infrastructure stability, with documented impacts across public utilities and the broader economy. Ongoing data from affected entities and law enforcement continue to quantify the scale through reported incidents, losses, and enforcement outcomes.
