MTN South Africa has unveiled the continent’s first concentrating solar cooling system to power the firm’s data centers.

“MTN is acutely aware of the impact of global warming and its adverse impact on emerging markets including South Africa. We continuously explore ways in which we can not only reduce our carbon footprint, but it will substantially reduce our electricity consumption which will release additional capacity for the national grid,” Zunaid Bulbulia, MTN South Africa CEO, said in a statement.

MTN Group is a Johannesburg-headquartered telecommunications firm that operates in 20 countries across Africa and also operates in the Middle East.

The cooling system, which is based in MTN’s head office in Johannesburg, is driven by Linear Fresnel Concentrating Solar Power (CSP) technology, which uses heat generated from the sun and has a peak cooling capacity of 330 kilowatts.

It also consists of 242 solar mirrors that cover a total area of 484 square metres which track the sun to generate pressurised hot water at 180 degrees Celsius. The mirrors move into a self-cleaning position when it rains, and turn down into a protective stow position on cloudy days.
