Energy Efficiency Opportunities - Assessment Handbook

Date

This handbook provides guidance for large energy users on how to effectively conduct an energy efficiency assessment.  It draws on the practical experiences of companies and consultants that have undertaken effective energy assessments and can help corporations plan and implement assessments in a way that will optimise business outcomes. The handbook was designed for corporations to meet the requirements of the Energy Efficiency Opportunities (EEO) program but can be used by any large energy user.

Energy-efficient equipment - Golden North

Date

Golden North is a manufacturer of premium ice cream and frozen yoghurt. Its South Australian facility at Laura consumes 6930 gigajoules (GJ) of electricity per annum, about 75% of which is used by the refrigeration plant. Energy assessment identified numerous areas for savings through energy efficiency improvements, including replacing inefficient compressors with a single crew compressor (and using variable speed drives to ensure it runs efficiently); installation of hot water exchangers for oil cooling and installing variable speed fans.

Energy Savings Measurement Guide

Date

This guide provides corporations with technical advice about estimating and measuring energy efficiency opportunities, presenting results to decision-makers and tracking and reporting the opportunities. It also provides guidance on how to identify and estimate the wider business benefits and costs from implementing energy efficiency opportunities. It was designed for corporations to meet the requirements of the Energy Efficiency Opportunities (EEO) program but can be used by any corporation seeking to improve the accuracy of their energy savings estimates and measurements.

Refrigerator head pressure reduction - Caernarvon Orchard

Date

At the JW Kirkwood Ticehurst Orchard in Tasmania, 58% of  the annual electricity spend of around $90,000 is for refrigeration of its cool rooms and other systems. In WA, Newton Brothers packhouse and cold storage spends 70% of its $350,000 annual electricity costs on cold storage.  Both could save money by reducing the head pressure in their refrigeration units. this would cost around $5000, save between $2500 and $3500 a year and have a payback period of just 1-2 years.  

Energy assessment and LED lighting - Caernarvon Orchard

Date

Caernarvon Orchard in Orange, NSW, produces and packs 4,500 tonnes of apples and 800 tonnes of cherries per annum. About 5% of its annual electricity spend is on lighting (around $3,400 pa). An energy audit found that replacing high bay lighting fixtures with LEDs would save $2,120 a year (from a one off investment of $5,600). Savings would also come from using electronic lighting ballasts, and replacing fluorescent tubes.

Installing fridge timers saves energy and money - Bottle King Liquor

Date

The average small-medium retail business can use 80,000 kilowatt hours (kWh) of electricity a year. This factsheet shows how one business, Bottle King Liquor, saved on energy costs to run its fridges. By installing fridge timers, the business saved $135 a year for the running costs of each of its 7 drinks fridges, a $950 annual saving that was paid back in less than 2 months.

Demand side efficiency: Savio Pack House and Cold Storage

Date

The 14 cold storage rooms at Savio’s, a fruit packing house in Queensland, are controlled by 3 large ammonia compressors, which an audit showed consumed over 435,000kWh (costing $95,000) in ten months. By avoiding demand changes which account for 40% of Savio’s total electricity costs, the business could save $5500 a year by shutting down equipment at certain times. 

Energy Efficiency Tools Review

Date

The Energy Efficiency Tools Review report provides a list of software tools used internationally for analysing energy use in the manufacturing, oil, gas, and power generation sectors. These software tools help users find energy savings in their business operations.
