Let Marvin tell you about reducing power losses and remember that you too can send us your articles by mail.
Different countries, regions, and power utility companies use different variables for billing and tariff structures. The primary objective of this article, thus, is not to focus on particular tariffs, rather, the basic elements that permeate across all the regions.
In short, I seek to highlight the two fundamental ways to reduce peak power demand and power losses in the generation and transmission.
Power Peak Demand Reduction
To get the most out of the generation and transmission company, the primary objective is to reduce power peak demand while seeking higher demand during the low load periods. Most power utility companies offer reduced tariffs at specified times of the day and year. Do note that the higher the peak demand, the higher the bill amount.
For large industries operating on LV and MV, there may be as many as four different rates used for calculation in the course of the day. The primary objective of the attending engineer is to get the maximum load, or shift the loads to maximize on the lowest rates.
