station, Herbst says EDM stipulated that it should be a self- contained, multipurpose unit able to accommodate a range of operational scenarios, including working in areas with limited infrastructure. “It can be used in emergency applications where it re places an existing switching station that might have failed, or it can be used in a standby role where it assists with temporary 33 kV distribution,” he says. “It’s also ideal for routine maintenance projects, where it might replace – for example – a switching station that is temporarily taken of fline. It is also, of course, suitable for any project under construction which might need a temporary 33 kV net work distribution. It is a simple operation for this unit to be tapped into an overhead line and feed power directly to the site.” The mobile system delivered to EDM follows closely on another recent notable success in Africa, which saw Zest WEG supplying a 50 MVA mobile substation, one of the largest ever built in South Africa, as well as a 33 kV mo bile switching station, to Electricité de Guinée , the national electricity utility in the West African country of Guinea. The scope of the turnkey project included three trail ers with specialised equipment, one of them being a cable reel trailer with all power and control cabling needed to connect the mobile substation and the mobile switching

station trailers into an integrated mobile energy system. “The latest Mozambican order as well as the Guinean project highlight Zest WEG’s ability to design and manufacture mobile solutions for almost any application, anywhere in Africa,” says Herbst. “We believe there is a significant and growing demand for solutions of this type, given that the continent’s electrical infrastructure is growing fast. Our delivery on these latest contracts underlines our ability to meet this demand.”
