Course Description

In 1882 Sir Thomas Edison built the world’s first electricity generating station in New York. The supply of Electricity spread rapidly across the globe in the ensuing years. Today, over a century later, the use of electrical energy has become commonplace. Global economics is rapidly changing methodology in the Distribution of Electricity throughout the world. Many Distribution Electricity Utilities have changed from State Ownership to Private Ownership and the trend is increasing worldwide.

Regulatory and shareholder pressures are now driving Utilities to deliver an improved supply performance and demonstrate a more commercial approach to their activities.An important step is to ensure that decision-making personnel possess sufficient up-to-date knowledge of distribution system behavior and modern distribution network design.
