Nest‚ tralac Researcher‚ comments on the current electricity crisis in South Africa Perhaps one of the most pressing challenges facing the South African economy in 2015 is maintaining the structural integrity of its electricity generation network. The power system has come under severe strain due to maintenance backlogs and a failure to bring new generating capacity timeously online to match economic and social development. This has led to electricity demand at times outstripping supply. Consequently

latest electrical meters which can be made to read automatically. Apart from the amount of electricity used‚ the solid state electric meter type can also record other parameters of the load and supply such as maximum demand‚ power factor and reactive power used etc. some of the advanced kinds of electric meters also include electronic clock mechanisms to compute a value‚ rather than an amount of electricity consumed‚ with the pricing varying by the time of day‚ day of week‚ and seasonally.

The Early Bird continuously calculates the marginal cost of delivering additional kilowatts of electricity to Southern Company customers anywhere in the company’s service area; then‚ as electricity demand rises or falls at points throughout the system‚ Early Bird transmits “raise” or “lower” impulses to the company’s generating units and routes the correct amount of electricity along the most economical transmission path to the end user. Periodically‚ Southern Company engineers test

The use of DG can be defined as an alternative to expand the capacity of the electrical system supply is being considered around the world. The use of small generating units‚ connected in a dispersed way at distribution/sub-transmission systems‚ can bring benefits to consumers and utilities‚ especially in places where there is deficiency of the electric energy transport system. However‚ the uncertainties involved in the planning and operation of system become bigger with the presence of DG. The impact

SCADA Vulnerabilities and Electric Power Industry Abstract Electricity is an essential element of life in the United States. It is crucial to manufacturing‚ business companies‚ residences‚ and certain methods of shipping. A deficiency in electricity can not only cause trouble‚ but also financial loss due to reduced business and manufacturing production. This paper will look at the basic concepts of SCADA (Supervisory Control and Data Acquisition) systems‚ their vulnerabilities in regards

How can India achieve inclusive growth to prevent the gap between rich and poor from widening? Inclusive Growth: A Paradox In Interests An essay by Hamza Ali‚ The University of Hull‚ UK Indian self reliance is a pipe dream that has consumed many of its greatest minds in the past half century. Its proponents often cite the litany of problems facing a nation whose population stretches to 1.1 billion and has hundreds of millions of people living in abject poverty
