1. Adrian Abbott & Jody Asquith Benchmarking Energy Consumption in Coal Mining

2. “I understand the value of developing a baseline to know my site’s performance, but how do I know where I stand relative to industry best practice?”

3. The Answer… Energy Benchmarking Benchmark energy performance –Site(s) performance relative to like operations –Typical ranges of performance –equipment level –process level

4. Benchmarking Energy Performance Where are we at?…. Established an energy baseline Developed sub process detail Identified energy performance metrics Reporting monthly, quarterly and annually…. …but how do I know where I stand relative to industry best practice? CHECK Benchmark Energy Performance! Map ALL of the above to like sites within the organisation, and Map ALL of the above to industry

5. Energetics’ Benchmarking Tool Utilises an energy dataset that has been built up and refined over 25 years of working with the industry How is your operation performing relative to other, similar operations and against industry best practice? How does the variability (range, frequency) of your own energy performance compare with others? Identify areas which should be targeted for improvement, even down to process or equipment type.

6. Electricity Consumption – O/C “Typical” site Focus on areas of highest consumption “Other” indicates more metering/ analysis needed

7. ACME Colliery Open cut mine using truck and shovel CHPP 7.5 million ROM tonnes/4 million tonnes product

8. Average site performance Energy intensity performance indicators: Understand industry average “per Saleable Tonne” allows for CHPP

9. Similar sites

10. Energy cost performance Understand range in energy cost per month of saleable coal during varying monthly production. Understand if your range is ‘above’ or ‘below’ average. Can be used as a high level ‘Trigger’ for further investigation.

11. Understand industry performance ranges and average Highlights smallest range ‘Min’ & largest range ‘Max’ Energy intensity performance spread – Quality of control! Here, ACME performs the best in class with a tight range.

12. Performance frequency Does ACME frequently perform within a certain target range? Why? Can frequency be improved to the left of chart? How does ACME compare amongst industry?

13. Drilling down… Identifies major equipment areas Seek to understand each unit in terms of its level of activity. Such as: High use by the pumps - is it because the pumps aren’t performing or does the site use too much water?

14. Summary Operational benefit Improve understanding of site performance (productivity, yield, etc) Financial benefits in lower cost of production As energy costs escalate, impacts will gain importance Energy management is another operational management dimension Identify largest stream & analyse/report Drill down Identify next largest stream… Should I accept what I see?

15. Next Steps “Harvest” the data from what you are already collecting Sub-metering and/or analysis to drill down deeper  Energy-mass balance  EEO Benchmark your results and identify areas to focus on for potential improvement
