Smart Grids Advantages: A smart grid delivers electricity from suppliers to consumers using digital technology to save energy, reduce costs, and increase reliability and transparency. The smart grid enables information to flow back and forth between electric power providers and individual… View Article

Load Sheeding

Power generators have limited capacities. When demand of electricity in a certain area exceeds its generation, the supply is to be cut temporarily as a method of reducing the demand on the generators. This temporary reduction in electricity supply is known as load shedding and less formally power cut. Peak load shedding hours are early… View Article
