(trading as DivFood)

Project Duration: May 2015 – March 2016

Value: ZAR 50 million / USD 3.6 million

Brief: Cogeneration /MV switchgear control/ Back Up Power

Alternator : Site voltage 400V : 11kV (400V direct in Paarl)

Providing modular backup power solutions to Nampak’s largest packaging production plants situated in Paarl, Western Cape (1MVA), Mobeni, Kwazulu Natal (4 MVA), and Vanderbijlpark, Gauteng (4MVA).

Trekkopje Desalination Project

Project Duration: July 2009 – December 2009

Value: ZAR 21 million / USD 1.5 million

Brief: Cogeneration /Substation control/ Back Up Power / Relocated Site

Alternator : Site voltage 400V : 33kV

Supplying Uramin Namibia (Pty) Ltd – part of the French Nuclear giant Areva – with a 6MVA (4x synchronised units) temporary solution (11kV) for commissioning of their new desalination plant. Once Nampower was able to supply power to the desalination plant, 4.5MVA of the 6MVA was relocated to the Uranium mine where it was combined with additional generators into the mine’s 11.75 MVA diesel standby plant. SWT introduced 5 new generators and 4 new transformers and associated switchgear (open air) to complete the new 33kV standby plant. The system offers cogeneration with Nampower (automatic control of consumer substation) and is used during periods of high demand to export power to Nampower.

Project Duration: January 2015 – May 2015

Value: ZAR 4 million / USD 290 000

Brief: MV switchgear control/Back Up

Alternator : Site voltage 400V : 11kV

SWT installed a 1.65MVA standby diesel generator, able to deliver 1320KW of power. The 12 cylinder Perkins engine is housed in a 40ft sound attenuated and weatherproof canopy. SWT engineers provided an 11kV Medium Voltage fully synchronised seamless power transfer solution allowing routine, non-disruptive testing and eliminating break before make plant return from generator power (following a power failure).

Project Duration: February 2010 – August 2010

Value: ZAR 3 million / USD 214 000

Brief: Back Up Power/MV switchgear control / Sound Sensitive

Alternator : Site voltage 400V : 11kV

A synchronised 2x 500kVA system with 11kV step-up into the site’s 11kV MV ring supply. The transfer system is once again a fully synchronised MV solution allowing seamless transfer between mains and generator power. The load can be transferred seamlessly to the generator plant prior to critical operations (mains supply are exposed overhead lines) and returned (again seamlessly) after completion by the plant supervisor.

Project Duration: July 2009 – October 2010

Value: ZAR 7 million / USD 500 000

Brief: Cogeneration / Back Up Power

Alternator : Site voltage 400V : 400V (including 3.3kV step-up step-down transmission)

Providing a complete overhaul of Cape Town Station’s back-up electricity supply as part of the Cape Town Station upgrade prior to the FIFA 2010 Soccer world Cup. The installation set new standards in terms of synchronised power via step-up & step-down transformers and offering power cogeneration.

Project Duration: November 2015 – February 2016

Value: ZAR 2 million / USD 145 000

Brief: Back Up Power / Energy Conscious

Alternator : Site voltage 400V : 400V direct

A 700kVA UK Perkins generator set, housed in a soundattenuated / weather proof canopy connected to the mainpower supply of the Woodstock Exchange building,including a 1250-Amp automatic changeover switch,providing a fully automated system.

Mpumalanga (Southgold Exploration (PTY) LTD)

Superwatt initially supplied 2 X 1120 containerized generators based on the UK-built 4000 series Perkins engines which were synchronized to replace the existing 1.5MVA generator. Due to the rapidly expanding system a further 3MVA system was supplied by Superwatt and successfully synchronized into the initial installation. Superwatt was awarded the contract to supply an additional 6MVA system which was incorporated into the current solution by October 2009.

Chapman’s Peak Drive

Superwatt supplied a super silent 125kVA Perkins generator to Tintswalo Lodges Group’s new Tintswalo Atlantic at the foot of Chapman’s Peak in Hout Bay. To meet the clients high standards at this exclusive five star Boutique lodge, Superwatt installed a unit which runs at less than 70db at a proximity of 1 meter

Global Aquaculture Solutions

Global Aquaculture Solution was awarded the tender to upgrade the brood stock facilities and install an emergency generator at the Research Aquarium, at Sea Point. Although the original requirement was for a UK Perkins, due to a time constraints ultimately the decision was made to purchase an OEM Caterpillar 375kVA ex stock which was modified to suit the tender requirements. This project is due for completion by April 2011.

Villiersdorp

An uninterrupted power supply was needed to safeguard the Betko cold store against any break in the cold chain since a single outage could result in the loss of the entire season’s export crop. Superwatt supplied its first two QST30 USA built Cummins (2x 1100kVA) to service the clients.

During the FIFA Soccer World Cup, held in South Africa in 2010, Superwatt was responsible for the complete power generation of the BBC’s temporary studios situated near the Cape Town Stadium.
To avoid any power disruption the BBC decided to run entirely on a UK Perkins 700kVA generator, supplied and maintained by Superwatt, during each of the 64 games played. The unit was fully synchronized to the grid and successfully operational throughout the tournament.

Newcastle, KZN

Superwatt initially supplied a 550kVA OEM Cummins unit to Brandyvine Valley Investment’s Uitkomst Colliery outside Newcastle in Kwazulu Natal to power their below-ground mining operation. This unit was converted from a 400V to a 525V output (a mining industry requirement) by using a step-up transformer. The mine placed a further order for a second 400V 550kVA unit 9 months later to power their above-ground operations.

Paarl

The original requirement, for Huis Vergenoegd in Paarl, was a back up generator which could power critical circuits of the main distribution board. Although it was possible to separate the circuits this would result in a more involved, and higher costing, installation. Superwatt proposed installing a larger generator which was able to supply the whole of Huis Vergenoegd with back up power in the event of a power failure. This was ultimately a more comprehensive option at lower cost to the client.

Hatfield, Pretoria

A generator was supplied to service the corporate head-office in Hatfield. Initially a 630kVA OEM Cummins unit was installed. This unit was subsequently upgraded to a UK-built Perkins 700kVA generator.

Adept Internet Solutions required an immediate installation of back up power, to which Superwatt supplied in the form of a rented OEM Caterpillar 275kVA.
This unit was supplied ex stock and will be available for purchase by Adept if they require.

Richard’s Bay

Superwatt supplied a custom-designed backup solution to BHP Billiton’s Hillside aluminium smelter plant in Richard’s Bay. The main supply of the system is a containerized 900kVA UK-built Perkins generator.
