Profile
City Power is the electricity utility responsible for supplying power to the Johannesburg metropolitan area in South Africa. It purchases electricity from the national grid and distributes it to residential, commercial and industrial customers through a network of substations, transformers and low‑voltage lines. The utility offers both pre‑paid and post‑paid billing options, enabling customers to purchase electricity via vending platforms or receive monthly invoices. Its core service includes maintaining reliable power delivery, managing outages and providing customer support for faults and inquiries.
As the primary electricity supplier for Johannesburg, City Power serves a large and diverse customer base that includes hundreds of thousands of households and businesses. The incident report from July 2019 noted that more than 250,000 pre‑paid customers were unable to buy electricity when the ransomware attack disrupted its IT systems. This figure illustrates the scale of its pre‑paid segment and the utility’s reach within the city. While exact total customer numbers are not disclosed in the source, the utility’s role as a major municipal distributor underscores its significant footprint in South Africa’s Gauteng province.
City Power operates as a municipally owned entity, which shapes its mandate to provide affordable and accessible electricity under the oversight of South Africa’s national energy regulator. Its distinguishing attributes include a strong focus on pre‑paid metering solutions and the maintenance of alternative fault‑logging platforms to ensure continuity of service during IT outages. The utility has demonstrated competence in restoring critical systems after cyber incidents, as seen when most services were brought back online following the 2019 ransomware attack. Additionally, it engages in public communication efforts, issuing apologies and guidance to customers during service disruptions.
Structurally, City Power is a subsidiary of the City of Johannesburg, with its governance overseen by a board appointed by the municipality’s council. It receives strategic direction and funding from the city’s budget while operating as a commercially oriented utility. Ownership by the local government aligns its objectives with municipal development goals, such as expanding access to electricity and supporting urban growth. This public‑sector backing also subjects it to regulatory reporting requirements and accountability to both the city administration and the national regulator.
