Rising fuel prices fuelling growth�

Opcon Powerboxes offer a hedge against rising fuel prices – they do not use fuel and pricing can be locked in for the entire contract period.�

Note: this slide uses the same assumptions as the customer case study. (1) fuel price increase based on forecast in IEA publication, “ World Energy Outlook 2008 ” (2) Fuel consumption reduces from 15.3 Million L/pa to 13.8 Million L/pa as Enerji provides 1 Powerbox unit of 0.7MW. (3) Diesel Fuel price at 2011 is $1/L (4) Enerji electricity price increase = 3% pa.�

Enerjiʼs primary target is off-grid power stations that supply electricity to remote mine sites .�

In WA alone there are 300 operating mines. �

We can sell direct to the mining company or via the Independent Power Producer (IPP).
