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 $0.85/L (4) Enerji electricity price increase = 3% pa.�
