Energy Efficiency – a Replacement to Load Shedding

Load shedding is one and only(a) of the biggest problem go virtually by everyone in Pakistan, no matter they ar domestic or commercial consumers. Pakistan is facing a serious muscularity crises and it whitethorn get worsened if not addressed seriously and promptly. Everyone is curious ab push through the role of government in dealing with this know and relieving consumers through immediate supply side solutions much(prenominal) as new provide sources. Government is vie its role in establishing new powerfulness plants and effectiveness of utilizing unleashed sources such as coal and renewable resources i. e. ind, solar etc.Domestic and commercial consumers sum to a greater extent than 60% in the entireness electrical nothing requirement of Pakistan. Currently, maximum dynamism deficit is 5500 MW in summers and immediate solutions atomic number 18 unable to meet this deficit in near future. It is not recommended to a consumer to agree on comfort by not operational so me of the high priority appliances but refined change in behavior may contribute much more than expected. Main electricity aim contributors are cooling and heating appliances used by domestic and commercial users.In order to define the impacts of such appliances, interrogation has been carried regarding the custom of get off conditioners in Pakistan. Consumers have been suffering from crises in form of excite shedding for hours in a day no immediate solution seems to be viable in extended summers. They tend to blame government and utility program companies for not reducing blame shedding. Energy could be made available for extended hours but a mass level awareness about good usage of readiness is required.Illegal connections, usage of unable and unnecessary appliances at peak demand clipping has worsened the situation and utility companies seem powerless about it. They are not left with both other option to reduce demand besides through load shedding. Air conditioner s are one of the major contributors in peak load in summer. They comprise 15% of the total peak load requiring at least 3000 MW for the country. A descry regarding usage of air conditioners was floated as a part of this research and 300 domestic and commercial consumers responded to the survey. peerless of the conclusions of the survey indicated that 21 0C is the average meet temperature for AC in households. From the same survey consumers were asked about the maximum control temperature used in household. The maximum average temperature was constitute to be 26 0C. In order to enquire 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. 2 rooms of the dimension of 12 X 16 X 12 ft were used for this purpose.One room was operated at 21 0C control temperature for 24 hours period while other at 26 0C. Observations and results indicated that a total of 0. 45 KWhr saving was enter 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 single day. In terms of power this can 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 nest egg could be of much important level. Due to on-going gas load shedding scenario, consumers may develop turning towards electrical heating appliances, which may potentially add up in electrical energy demand in near future. Large casing awareness is required at each level of consumption. Peak load shifting, discouraging illegal connections and utilizing energy in efficient way are our a couple of(prenominal) life lines. A single consumer contribution may seem insignificant but as a whole it can contribute toward s reduction of significant peak load.
