Innovative Solar Microgrids Transform Informal Settlements in Johannesburg
City Power has made significant strides in providing sustainable and legal electricity to informal communities across Johannesburg. Their Shalazile solar project recently received recognition as a runner-up for its efforts in offering safe, reliable power without the need for illegal connections. This initiative is part of a broader strategy to reduce dependency on Eskom and bring energy access to underserved areas.
A New Era of Energy Access
The Shalazile settlement in Denver, established in November 2023 as a temporary shelter for victims of the Marshalltown fire, now benefits from a multimillion-rand solar power system. This project, implemented by City Power in collaboration with the City of Johannesburg, ensures that residents have access to clean and legal electricity. The initiative was honored at the 2025 South African Photovoltaic Industry Association (SAPVIA) Awards, where it was recognized in the socio-economic development category.
City Power General Manager Isaac Mangena highlighted the significance of the award, emphasizing that the project provides safe access to electricity without the risks associated with illegal connections. He noted that Shalazile is just one of many similar projects under development. The utility’s plan includes the first solar-powered microgrid program run by a city in the southern hemisphere, aligning with its 10-point strategy to reduce Eskom reliance, minimize energy losses, and provide power to informal settlements.
Expanding the Initiative
City Power’s solar microgrid program began in Alexandra at the Amarasta settlement and has since expanded to Vlakfontein, which is larger than Shalazile. The initiative is also spreading to Vukani and The View. The CEO of City Power, Tshifularo Mashava, emphasized that the SAPVIA award represents more than just technological achievement—it symbolizes the utility’s commitment to improving people’s lives through legal and safe energy solutions.
Mashava pointed out that the Gauteng government supports this initiative. The solar microgrids offer reliable electricity even during blackouts and help prevent cable theft, ensuring greater security and stability for the communities they serve. The City Power Board Chairperson, Makhosini Kharodi, stated that the recognition validates the effectiveness of their energy plan, noting that the utility is not waiting for change but actively building it.
Broader Impacts and Future Goals
Beyond the microgrids, City Power is installing solar panels on clinics, schools, and its own buildings. They are also adding solar streetlights in informal areas and upgrading gas turbines to enhance backup power. These efforts are all part of a comprehensive approach to reducing dependence on Eskom and promoting a fairer energy future.
Mashava expressed optimism about the future, stating, “This is just the beginning. We’ll light up every community, one microgrid at a time.” The initiative reflects a shift towards decentralized energy solutions that empower communities and ensure long-term sustainability.
Lessons from the Shalazile Project
The Shalazile camp was originally built on a site intended for a vehicle pound. Despite spending R45-million on the project, the facility never opened. However, the land has been repurposed to provide essential energy services to the community. Resident Themba Mdlalose shared his satisfaction with the project, highlighting the importance of constant and safe power for the residents living at the camp.
City Power’s innovative approach demonstrates how renewable energy can be harnessed to address social and economic challenges. By focusing on sustainable solutions, the utility is paving the way for a brighter, more equitable future for Johannesburg’s informal communities.
