Zest generator sets resolve standby power issues

July 2016 Electrical Power & Protection

Power outages have become increasingly frequent with a widespread knock on impact across industry. The ability to provide fit-for-purpose standby power solutions is what distinguishes Zest WEG Group’s Generator Set Division.

Standby power solutions can range from a single diesel-driven generator set to a total standby power solution depending on the size of the building or project in question. Larger contracts often require a blend of smaller and larger generators to meet the needs of the various elements within the project. In all instances, fast reaction times from suppliers and the deployment of a reliable and durable generator set should be the standard.

A diverse set of solutions

Zest WEG Group’s Generator Set Division has built a solid reputation with a large number of clients over a diversity of industries, clearly demonstrating its capability to cater for large-scale standby power projects. A number of recent contract awards highlight the company’s ability to provide solutions that range from standalone generator sets to turnkey power stations, such as the one supplied to AVI Group’s Indigo Brands.

This original equipment manufacturer is responsible for the total project management and control coordination, including the testing and commissioning of entire systems. Close cooperation with the customer ensures that the design of the standby power solution seamlessly integrates within the overall structure of the building, to allow the equipment to be easily accommodated.

The scope of supply on the Indigo Brands project comprises three 1000 kVA generator sets and three 1000 kVA transformers. Zest WEG Group’s Generator Set Division is also designing a custom-built electrical panel for distribution, interfacing and synchronisation purposes. The company will additionally be supplying a 23 000 litre bulk fuel tank system, as part of the optimum solution.

In another a recent refurbishment contract, a containerised standby power solution was supplied to a client at the V&A Waterfront. Craig Bouwer, projects and product manager at Zest WEG Group’s Generator Set Division explains that after discussions with the customer it was determined that this would provide the most cost effective solution.

The project involved a ‘rig-out’ of the existing equipment from the original building, designing and fitting a sound-proof canopy, louvres and a base frame adaptor, to allow the generator set to be housed outdoors, as well as final testing of the newly containerised unit.

Silo 1 tenant, Allan Gray, occupies a Green Star building that requires adherence to specific environmental regulations. Zest WEG Group supplied a customised solution on this flagship project that met the latest European Tier 3 emissions control regulations. The system, which incorporates specialised switching controls to ensure continuous power at a major data centre, is designed to reduce the exhaust emissions from diesel-powered generators, which include nitrogen, hydrocarbons, carbon monoxide and particulate matter in the form of any visible smoke and soot.

“The V&A Waterfront is only one of many flagship projects that Zest WEG Group’s Generator Set Division has been involved with. Another notable project is Century City, a 250 ha mixed use development in Cape Town that combines office, retail, residential and leisure elements. We are in the process of supplying and installing one 400 kVA and two 800 kVA generator sets for the Urban Square residential, hotel and conference project at Century City,” says Bouwer.

Key to Zest WEG Group’s Generator Set Division’s success on such specialised projects is its ability to devise innovative solutions. To this end, it offers 20 kVA to 250 kVA off-the-shelf products, 300 kVA to 2 000 kVA individual customised units, as well as multiple sets to achieve turnkey solutions in excess of 12 MVA for large-scale applications or projects. All gensets are sold with a standard 12 month warranty, and maintenance contracts are also available for all applications. A notable differentiator is that the company offers a 24/7 breakdown support service.
