Energy Audits

Procex is able to perform Level 3 Energy Audits based on AS3598, and/or the "Energy Efficiency Opportunities Industry Guidelines".

Typical phases of the process are as follows:

Baseline Data

This analysis phase includes:

         Preparation of monthly and seasonal energy consumption profiles

         Tariff analysis of all forms of energy used on site

         Compiling a Baseline Energy Use Table and trends.

Energy Management Review

A review carried out with management including:

         Senior management commitment to, and involvement in energy management

         Understanding of energy savings potential in operations, maintenance and capital works

         Management of energy targets and key performance indicators

         Energy metering and monitoring

         Energy management reporting

         Energy supply management and alternative energy supply options

         Incorporation of energy management into operating and maintenance procedures

         Accountabilities for energy management

         Training and awareness procedures

         Compliance with legal or other requirements

         Identification and assessment of actions needed to improve energy management systems.

Technical Review

The technical review phase includes:

         Preparation of an energy balance for the site

         Detailed analysis of the site energy usage including:

o        Utility operation and services

o        Plant and equipment operation

o        Control systems

o        Maintenance schedules

         Identify other energy saving opportunities by investigation of processes and experience

         Identify appropriate energy use targets for major energy users

         Consider the impact of scheduling and lengths of production runs on energy use

         Investigate opportunities to reduce peak electrical demand

Savings and Costs

This phase delivers a prioritized list of recommendations to reduce energy consumption and cost:

o        Capital works -

         Description of the work involved in implementing each recommendation

         Predicted annual energy and cost saving for each recommendation

         Expected cost of implementing each recommendation

o        Management options

         Provision of energy sub-metering

         Changes to maintenance and operating practices

         Modifications and/or additions to existing plant

         Alternative fuels

         Alternative tariff structures

         Alternative staffing arrangements

         Staff training and involvement in energy management practices.


For each recommendation, the list will show:

         Comparison of benefits and costs

         Internal Rate of Return for the recommendation

         Time required to implement the recommendation

 

The energy plan should form the justification for further investment in energy saving initiatives. Detailed economic analysis of these initiatives provides a firm estimate of savings and costs.

The methodology used is based on:

o        "Energy Efficiency Opportunities Industry Guidelines".

o         Guidelines for Energy Savings Action Plans (NSW Dept. of Energy, Utilities and Sustainability),

o        Australian Standard AS3596 Energy Management Programs Guidelines for definition and analysis of energy and cost savings,

o        Australian/New Zealand Standard AS/NZS3598 Energy Audits.
