LED lighting as energy management tool through correlation analysis of daily electricity demand and supply curve

Abstract

Power industry has restructured in last decades and now it has become a commodity rather than a utility with the maximization of profit as its main purpose. Peak ripples in the electricity demand curve could disturb the economic generation. In developing countries, Electric Supply Companies are unable to meet the existing power demand due to unfeasible and unjustified fuel burning. Therefore, they are left with load shedding as the only Demand side solution. It is a well-known fact that the Light Emitting Diodes (LED) Lighting could be used to conserve electricity. However, LED could also be used as an energy management technique without affecting the comfort level of consumer. Electricity demand and supply curves could be correlated up to 93% through this option. Argument is supported by correlation analysis of estimated daily demand and supply curves of Karachi Electric Supply Company (KESC). Estimated curves are developed through LED lighting energy conservation analysis on KESC summer and winter demand curves. Finally, from global perspective, LED lighting is not only a remedy for removal of peaks and ripples in demand curve but also a feasible solution for global climate problems through energy conservation and low carbon emissions.
