I'm not sure if the edits I made to the text were uploaded correctly, so I'm rewriting them here. (Two comments, because the text won't fit in a single comment)

Electricity is distributed from power stations through wires carried by pylons and extended underground. The produced electric current is of the alternate type (AC), as it is easier to manage voltage with AC than with direct current (DC).
Higher voltage is preferred, because the waste of energy due to the resistance in cables diminishes, and the current needed to transmit the same quantity of electric power is lower.
An average power plant can produce about 1 million KW of electric power at 25.000 V. The voltage is increased to 400,000 Volt by step up transformers through a grid system.

High voltage is necessary for industries, while for various locations such as small factories, offices and houses, voltage must be reduced by step down transformers.
The needed energy varies throughout the day: for example, on winter evenings the use of energy is higher for lighting, as well as in the morning when electrical appliances are used by housewives.
At night less energy is required and for this, an energy control system dispatches energy on demand.
A general blackout may be due to events like storms and the collapse of pylons; it may be necessary to resort to different lines or to the electricity grid of other companies.

(My voice cracked a little on the word "dispatches," sorry!)

HI, thank you so much , you're really kind, the your voice and spoken speed are perfect. :)
