Those huge electricity transmitters and substations that you have noticed are much more complex than you would think. Power transmission all around the work is a specialized job done with the help of specific equipment and even a small error in these products or services could cause a big trouble in the affected area. From your air conditioners to your mobiles everything is powered by electricity and the government and some private firms are responsible for this bulk movement of electricity.
Even a second without electricity could seem like a curse, thus one of the most important functions of the public sector becomes to develop a highly efficient electricity distribution and transmission system. The need of households, factories or hotels could vary in the terms of the amount of power demanded and hence the capacity and of the residential and commercial facilities vary.
A power plant could be a nuclear reactor or hydro-electricity plant, and from that area, the power has to be effectively transmitted through a complex system of wires and lines which are interconnected. Catering to the commercial and domestic needs of the end receivers becomes the priority of the transmission developers. Thus, as huge as this process seems to be at first, it is equally personalized in a manner. The building block of this process of transmission and distribution is the power grid.
The New Entries
Traditionally, the process of developing power grids and transmitters was fully controlled by the government in a majority of the countries looking at the importance and safety constraints posed by the industry, but now many private companies which are reputed have also joined the field. These companies and developers have developed bigger and better power grids which have put the public sector in this regard to shame.
These transmitting corridors which are interconnected ensure that all the household or industry in the particular area are powered continuously and in a cost-efficient way. The transmission turns out to be a challenge especially in an area which could be considered as load centers (especially industrial).
The Resource jungle
It is a well-known fact that to produce electricity, an area rich with hydro, solar or tidal power and with coal will have better electricity production and would sell the excess electricity to the power-deficit states. Thus, this transfer of large-scale power over long distances becomes a challenge which is only overcome by the commercial substations and transmission lines. These private companies have foreign investments and tie-ups as their backbone, which provides them an innovative solution with limited investment on research and development.
The true power
It has been observed that innovative solutions are being developed to control the capital expenditure in setting power lines and making them much more integrated. Technologies are being developed to minimize the power loss while its transmission. On tricky landscapes, helicopters can be used to set the stations and equipment and wires.
