How are engineering companies addressing the issue of energy efficiency?
Ingenuity & insight – the Ausenco group | June 2012 2
Focussing Questions:
•When is 'energy efficiency' important?•What is 'energy efficiency' to a project developer? •What is the measure of 'energy efficiency'?
•How does this impact on technology selection?

When is 'energy efficiency' important?•Limited or very high cost energy (water) supply•Good corporate citizenship•Operating costs optimisation•Optionality – unreliable and multiple supply systems

What is 'energy efficiency' in project development?
•Process selection - particularly comminution•High efficiency drives•High efficiency lighting•Optimised materials handling (trucking, conveying and pumping)•Optimised elevations•Water recovery efficiency – (water can cost $4/m3)

What is the measure of 'energy efficiency'?
$ cashflow, NPV, ROV
• Energy cost and supply risks are factored in• Corporate 'good citizen' policies are considered
• kWh/t ore processed?• kWh/t metal produced?• t CO2/t ore produced (including inherent energy)?• t CO2/t metal produced (including inherent energy)?

A cycle•Need•Idea•Innovation •Cost reduction
•Paradigm shift (only when cost effective)

Energy efficient operation Cost inefficient
(unless you are a taxi operator)

Conclusions•Energy efficiency is a sub-set of cost effectiveness•The key driving forces are commercial
– Energy costs– Energy supply limitations– Revenue implications
•To optimise energy efficiency requires a 'business optimisation perspective'
