Unformatted text preview: energy improvement can be made. The energy monitoring system enabled the plant’s energy team to identify several energy savings opportunities, and in 2009 their cumulative efforts resulted in saving 10M kWh at a value of $490K. 29 30 Thermal energy Our efforts to increase the use of alternative fuels as much as possible will be stepped up in the coming years. This year a revised target has been set to increase the alternative fuels sub­ stitution rate at Group level to 10.0% (calorific basis) by 2017. The largest source of thermal energy (98.5% calorific basis) was due to use of conventional fuels: coal, pet coke, fuel oil and natural gas.
