South Africa: Fresnel Collectors Keep It Cool in MTN’s Server Rooms

Submitted by Baerbel Epp on August 28, 2014
Industrial SolarSince June 2014, a Fresnel collector field with 242 kWth has been feeding into the district cooling system of the MTN Group at its headquarters in Johannesburg, South Africa. MTN, which has more than 200 million customers, as well as subsidiaries in 22 countries across Africa and the Middle East, is one of the leading mobile operators in South Africa – and it is aware of the impact of global warming. “We continuously explore ways in which we can lessen the impact of our operations on the environment. This initiative will not only reduce our carbon footprint but it will substantially reduce our electricity consumption, which will release additional capacity for the national grid,” MTN’s CEO, Zunaid Bulbulia, was quoted as saying in a press release from 17 July 2014. The concentrating solar thermal plant powers the double-effect absorption chiller whose cooling capacity of 330 kW keeps temperatures low in the data centre at MTN’s head office.
