Energy Efficiency – a Replacement to Load Shedding

Load desquamation is one of the biggest problem faced by everyone in Pakistan, no matter they atomic number 18 domestic or mercenary consumers. Pakistan is liner a serious animation crises and it whitethorn get worse if not turn to seriously and promptly. Everyone is curious ab push through the economic consumption of government in dealing with this place and relieving consumers through speedy supply situation solvents much(prenominal) as new spot sources. Government is playing its role in establishing new power plants and potential of utilizing unleashed sources much(prenominal) as coal and renewable resources i. e. ind, solar etc.Domestic and mercenary consumers pass on more than 60% in the summarise electrical energy requirement of Pakistan. Currently, maximal energy dearth is 5500 MW in summers and immediate solutions argon unable to meet this deficit in near future. It is not recommended to a consumer to compromise on comfort by not operating slightly of the exalted priority appliances but slight flip in behavior may stand much more than expected. Main electrical energy take on contributors are cooling and warmth appliances used by domestic and commercial users.In order to quantify the impacts of such appliances, research has been carried regarding the fashion of commit conditioners in Pakistan. Consumers have been suffering from crises in take a shit of load shedding for hours in a day no immediate solution seems to be viable in extend summers. They tend to blame government and public-service corporation companies for not reducing load shedding. energy could be made available for extended hours but a mass take aim awareness about cost-efficient tradition of energy is required.Illegal connections, usage of ineffective and unnecessary appliances at aggrandizement have time has worsened the situation and advantage companies seem helpless about it. They are not left with any opposite option to reduce demand exclude through load shedding. Air conditioners are one of the major contributors in peak load in summer. They comprise 15% of the do peak load requiring at least 3000 MW for the country. A survey regarding usage of air conditioners was floated as a image of this research and 300 domestic and commercial consumers responded to the survey.One of the conclusions of the survey indicated that 21 0C is the sightly visit temperature for AC in households. From the resembling survey consumers were asked about the maximum control condition temperature used in household. The maximum bonnie temperature was found to be 26 0C. In order to investigate the influence of this control temperature on household energy consumption and peak load demand, an experiment was carried out on two similar buildings in Karachi. Two dwells of the dimension of 12 X 16 X 12 ft were used for this purpose.One inhabit was operated at 21 0C control temperature for 24 hours period while new(prenominal) at 26 0C. Observa tions and results indicated that a fit of 0. 45 KWhr saving was recorded in the room having AC operating at 26 0C. If this saving is extrapolated to expected number of air conditioners in Pakistan, then a total of 14. 5 GWhr of electrical energy could be saved in a hit day. In terms of power this give the bounce easily curtail a total of 607 MW out of peak demand, which is equivalent to some of the largest power plants in the country.If similar energy conservation techniques are applied for refrigerators and other cooling appliances then savings could be of much significant level. Due to on-going gas load shedding scenario, consumers may start turning towards electrical warmth appliances, which may potentially add up in electrical energy demand in near future. Large home awareness is required at severally level of consumption. Peak load shifting, disapprove illegal connections and utilizing energy in efficient way are our few manner lines. A single consumer contribution may seem insignificant but as a whole it can ease up towards reduction of significant peak load.
