Energy Audits

Procex is able to perform Level 3 Energy Audits based on AS3598, or Energy Savings Action Plans conforming to the Guidelines for Energy Savings Action Plans published by the NSW Dept. of Energy, Utilities and Sustainability (DEUS). 

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        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.
