Independent data centre operator Teraco is expanding its facilities in Johannesburg and Cape Town and building a new centre in Durban as demand in the SA market explodes. But it’s having to focus enormous energy on increasing power efficiencies at all the sites in order to try to combat the effects of fast-rising electricity tariffs. Teraco MD Lex van Wyk says companies have been hard hit by the latest electricity increases and “this will only worsen”. “We’re taking every step in managing our facilities better so that our clients are not affected as seriously as they could be,” he says.
