Power Generation Equipment 6 x 1MW units combine to provide 5 MW of continuous temporary power HV Transformer HV supply direct to client
Typical 6 Pack Power Project (5 MW)
Benefits to the mining customer Low installed capacity cost per KW No expenditure on capital equipment Availability of power within days of contract signing Minimal site preparation High flexibility for upsizing or downsizing plant capacity High degree of reliability Convenient extendible option circumvents long term commitment Risk mitigation
Mongolia Early production Situation The second largest copper and gold mine was being constructed in the Gobi Desert, Mongolia. With no utility power available to begin sinking shaft, underground mining was a problem. Solution Aggreko provided 4MW temporary power package in a standard 6 pack configuration, five 1MW units plus HV transformers.
Chile- construction power Situation CODELCO s construction of one of the biggest copper projects, Gaby Mine, required temporary power during the 17 months of construction. Solution Aggreko presented a power plant capable of delivering a continuous power output of 2720kW @ 23kV for all the 17 months of construction.
Australia bridging power Solution Downer RML at Area C Mine, Newman Australia, needed a temporary source of power until the grid supply could be connected in the area. Situation - Aggreko supplied a power package of 11MW at 33kV
Guinea breakdown and maintenance Situation - Alumina Company of Guinea needed power to install a new boiler, deal with a generator breakdown and an explosion of the existing boiler Solution - Aggreko provided and installed, in less than 2 weeks, a power plant supplying continuous power of 5.95MW / 5.5kV.
South Africa Wheeling power Situation Due to a power crisis in South Africa in 2008, guaranteed power was required for a mine already connected to the grid with no availability. Solution Aggreko supplied a 10 MW plant at Mossel Bay in a wheeling power agreement. i.e. Aggreko guaranteed the power to the grid who in turn guaranteed it to the mine.
Eritrea base load for gold processing plant Situation Due to the remote location of the mine (300km from the coast) the short construction timeframe and the relatively short mine life, the client was looking for a guaranteed power supply without having to invest in infrastructure. Solution Aggreko supplied a 20 MW plant at Bisha as the sole source of power to the processing facility. The initial agreement has an option to extend on a year by year basis.
DRC mine construcion and processing plant Situation Due to the remote location of the mine power is required in 3 stages for construction; for initial production over the first 2 years and for the main production where a hydro powered plant has been planned. Solution Aggreko supplied a 2 MW plant at the mine site for the camp and initial construction power. This will increase to 11MW as and when the mining operation is big enough to require it. Once the HEP plant is installed and running, the equipment may be transferred to another site or off-hired.
Financial Benefits Complete turnkey solutions Rapid deployment, installation and commissioning No capital expenditure, only monthly cost No amortisation of power station over mine life Flexible phased delivery, reducing cost Guaranteed power what all miners want What does it cost?
