Zest WEG to provide generators for Leonardo skyscraper
South African power manufacturer Zest WEG has supplied Johanesburgs Leonardo skyscraper with back-up generator sets in order to keep the power going during outages.
The generators will provide the building with emergency power backup and comprise prime-rated Mitsubishi-powered diesel generators coupled to WEG alternators. To reduce noise levels to local council requirements, Zest WEG Group supplied and installed inlet and outlet splitter attenuators. The fuel storage and transfer system ensures eight hours of operation, with bulk and day fuel tanks installed in compliance with local fire regulations.
The company also installed medium voltage (MV) generator protection and a control panel, as well as a main MV distribution panel for the building, comprising six tiers for all incoming supply and feeder breakers. All the related cabling for the MV and low voltage (LV) reticulation were also provided for the generator sets, fuel system and auxiliary control equipment.
The iconic structure, that will dominate the skyline as the tallest building in Africa, is being built for 75 on Maude (Pty) Ltd, a partnership between Legacy Group and Nedbank Limited.
According to Craig Bouwer, projects and product manager at Zest WEG Group genset division, the commissioning of the units was undertaken in the first quarter of 2019 with practical completion expected to be reached in the second quarter of 2019. This follows the original awarding of the tender in November 2017.
“We are proud to have designed, manufactured and supplied the two 2,000 kVA, 11 kV generator sets which we are installed in the Leonardo’s dedicated plant room on ground level,” says Bouwer.
“Our contract included delivering the units to site and placing them in position, which was done in September last year. We were also responsible for the complete installation, testing, commissioning and handing over to the client in full working order.”
