Power factor correction - Woodburn Orchard

Date

The Woodburn Orchard’s facility in Batlow New South Wales produces and packs around 4000 tonnes of apples a year. Woodburn is classified as a large enterprise when compared to other orchards that were audited.

Energy efficiency improvements - Alto Hotel

Date

The Alto Hotel on Bourke in inner city Melbourne aims to lead its field in energy efficiency practices. Changes are extensive and have included equipping air conditioning with inverter and moment sensor technology (an $8000 saving); finding ways to optimise heating in an heritage building (solutions include staggered stud wall systems, multiple layers of floor coverings, and heat reflecting, double glazed windows). This factsheet outlines many of the 4-star hotel’s initiatives to bring energy efficiency to the front of its business model. 

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 management - Falls Festival

Date

The Falls Festival is a 3 day music festival held across Australia. Organisers of the Tasmanian event, at Marion Bay, were interested in reducing its fossil fuels consumption, and the savings that come with that. Assessments showed the primary opportunity to save came with selecting the right sized generators: there are 26 generators on site and changed practices were able to cut 90 running hours of usage by powering them down at appropriate times, and by choosing the right generator for the job throughout the festival. 

Energy management - Capilano Honey

Date

At Capilano’s Richlands honey production facility, electricity and natural gas are the primary energy sources and input costs. Of the 18,000 gigajoule (GJ) (a cost of $580,000) used on site, 25% is used by thermal loads of pasteurisation and hot water generation. An assessment took into consideration upcoming business changes (the build of a new facility was pending) and advised Capilano about opportunities to save money on lighting, solar PV, thermal system insulation and heat recovery, and compressed air heat recovery.

Energy assessment and LED lighting - Caernarvon Orchard

Date

Caernarvon Orchard in Orange, New South Wales, produces and packs 4500 tonnes of apples and 800 tonnes of cherries per annum. About 5% of its annual electricity spend is on lighting (around $3400 pa). An energy audit found that replacing high bay lighting fixtures with light emitting diodes (LEDs) would save $2120 a year (from a one off investment of $5600). Savings would also come from using electronic lighting ballasts, and replacing fluorescent tubes.

Energy assessment and management processes - Incitec Pivot Plant Gibson Island

Date

The Incitec Pivot plant at Gibson Island in Queensland used about 13 peta joules (PJ) of energy in 2008–09 in the manufacture of nitrogen-based fertilisers. This case study describes 3 projects estimated to save 150,000 giga joules (GJ) of energy annually. This case study was developed as part of the Energy Efficiency Opportunities (EEGO) program.

Energy assessment - Thiess' Australian Mining business unit

Date

Thiess’ Australian Mining business unit, through effective use of the Energy Efficiency Opportunities (EEO) Assessment Framework, found new efficiencies and dollar savings. The projects implemented were payload management, automating mobile lighting equipment, plant idle-time management, and turbo idle-down time.

Energy efficient Showcase Bakery - Bakers Delight

Date

Bakers Delight’s designed a showcase bakery at its operation in Mascot. The bakery showcased best-practice building design, baking procedures and equipment efficiency, achieving a 32% reduction in annual energy costs compared to a standard Bakers Delight bakery. This was achieved without impacting on product quality, customer satisfaction or staff comfort.

Measuring and monitoring energy use produces big savings - Murray Goulburn Cooperative

Date

A team-based approach relying on ‘people know-how’, combined with sound measuring and monitoring, has enabled a dairy processing company to gain impressive bottom line savings. The 12 month pilot project, which measured energy use in the various stages of milk processing at the Rochester (Victoria) Branch of Murray Goulburn Cooperative, achieved savings of $400,000 a year with a reduction in greenhouse gas emissions of 3,500 tonnes.
