This case study examines the adoption of battery-powered electric vehicles (BEVs) by District Watch Group, a Cape Town-based security company, to improve operational resilience and reduce costs. The company has integrated 8 BMW i3 EVs into a 60-vehicle fleet, demonstrating a significant reduction in maintenance and fuel expenses compared to internal combustion engine (ICE) vehicles.

• District Watch Group has achieved an overall cost reduction of approximately 80% over the life of its electric vehicles compared to its internal combustion engine (ICE) fleet. This is primarily attributed to significantly lower maintenance costs, as EVs avoid the gearbox replacements typically required for ICE vehicles in their second year, and a fuel cost saving of between R120 and R160 per shift.
• The operational viability of the EV fleet is supported by a range that exceeds the company's requirements. While the BMW i3 has an expected range of 290-320 km, District Watch Group only requires a maximum operational range of 200 km per shift to maintain swift response times and minimize vehicle wear and tear.
• The transition to EVs has extended the expected vehicle lifespan from the industry standard of 3-4 years for ICE vehicles to 5-6 years for the BEVs. The company's current EV pilot consists of 8 battery-electric vehicles within a total fleet of 60, with a battery guarantee of 10 years.
• Despite the operational savings, several barriers to EV adoption persist, including higher upfront capital costs, higher insurance premiums, and increased tyre wear due to regenerative braking. Additionally, the company faced technical challenges with the vehicle chassis structure, which required innovation to install radio communication equipment and security lights.
• The document identifies critical infrastructure needs to support EV growth in Cape Town, including the development of specific EV electricity tariffs that incorporate rooftop solar PV, the establishment of a safe and accessible public charging network (such as in malls), and the implementation of 'spot charging' arrangements.
