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.
