In summer 2007/08 Western Power launched its inaugural air conditioner trial. The air conditioner trial is a demand management initiative which provides an innovative solution to managing peak electricity demand. Western Power conducted the trial in the areas of Nedlands, Claremont and Dalkeith. These suburbs have high peak demand over summer. The majority of peak demand can be attributed to air conditioners.
Cool Community - Clean Future was well supported by the local community with over 1000 residents registering to take part. The trial involved installing switching devices on refrigerative or reverse cycle air conditioners in the homes of participants. The devices enabled Western Power to alter the air conditioner compressor's regular pattern of switching on and off. The devices are activated when the outdoor temperature exceeds 36C. The air conditioner's fan continues to operate as normal, circulating air around the home.
Western Power reduced peak electricity demand in a metered sample of Nedlands, Claremont and Dalkeith participants by 27 per cent during selected periods of peak demand days. This means each volunteer reduced their power use by 3.5 kilowatts per day for each day they were switched. This is the equivalent of using four microwaves or two pool pumps. It is a substantial saving for a first trial.
Western Power is committed to providing a green energy solution to the ongoing issue of peak electricity demand during summer. The trial is just one part of a toolbox of solutions that Western Power is developing to address peak electricity demand, energy efficiency and emission reductions.
