Studies in the USA indicate that the world's electrical consumption is set to rise to 30 billion kWh by 2030 from 15.4 billion kWh in 2006. Governments and utilities today need to plan to supply large amounts of electrical energy efficiently, inexpensively and with minimal impact on the environment.

In countries with growing populations and rising economies, such as Brazil, China and India, demand for electricity will become intense and the challenge will be to deliver large quantities of electricity from power generating stations to urban centres that can be thousands of kilometers away. Ultra high voltage, or UHV, offers the promise to meet this challenge.

UHV is needed to deliver electricity to cities without increasing the number of transmission lines. In growing cities where demand is on the rise but room for transmission lines is limited this is critical because it means only one power line corridor is needed, not several.
