MMG Case study

- MMG production was highly impacted

by unreliable power from grid

- In end 2012 Aggreko and MMG entered

in formal agreement for a 12MW/33KV

power plant in continuous and 4MW/33

KV in standby, all diesel powered

- End of 2013 this agreement has been

extended to a further 8 MW/33 KV

diesel to reach a total of 24 MW

capacity. The entire power is planned to

run at least up to end 2015.

- This capacity can be ramp up of down

depending of quality of power from grid

MMG: testimonial

MMG request that Aggreko maintain a minimum of 5 generators on line in order to keep power to the site following a trip of the utility supply. Load shedding disconnects the main productive loads at these times and retains light & power to the plant. There is a significant SAFETY benefit in keeping the lights on after these outages. This also allows a restart of the plant very quickly after an outage. Aggreko power is used initially with a swap over to utility power as soon as it becomes available. The ability of the Aggreko station to synchronise additional generators immediately following an outage certainly allows us to ramp up the power draw and get back to producing copper. The primary benefit where production is impacted is any time that Aggreko operates more than these first 5 sets. All MWh produced by these extra generators will be utilised to produce copper. A conservative estimate of copper produced would be one tonne of copper for every 3MWh. The cash flow impact for Kinsevere would be approximately 50% of the LME price for this extra copper produced

Sum up, Q&A

- Reliable power generation is critical

for mining companies

- Uncertainty on power quality and

availability from grid and import

- Issues of grid are temporary

- You are expert in mining, not power

producers

- Aggreko is the world and DRC

leader for this type of services
