Low-carbon Huawei campus in Johannesburg: Powered by a rooftop PV system and a BESS

Coal has long accounted for the lion's share of South Africa's electricity mix. To help advance the country's decarbonization and make our own operations greener, we deployed a rooftop PV system on our Johannesburg campus, significantly reducing the campus's reliance on coal-fired power and cutting its carbon emissions. The project also involved deploying a battery energy storage system (BESS) to store surplus electricity generated by the PV system and release it as needed. This system boosts energy utilization and helps ensure a stable power supply.

In 2025, the rooftop PV system generated more than 600,000 kWh of electricity, equivalent to cutting CO₂ emissions by 595 metric tons, powering the campus's green operations. This project showcased our sustained investment in and commitment to green technology and sustainable operations.

The PV + BESS solution maximizes the environmental benefits of renewable energy while significantly boosting the campus's operational resilience in complex energy conditions
