What is the primary function of an electrical grid?

The primary function of an electrical grid is to deliver electricity from producers to consumers reliably and efficiently. This involves the infrastructure that transmits electrical energy generated by power plants—whether from renewable sources, fossil fuels, or nuclear plants—through transmission lines and distribution networks to homes, businesses, and industries.

The reliability of this delivery is paramount; the grid must ensure that electricity is available when needed, balancing supply and demand in real-time. Efficiency is also a key aspect, as the infrastructure must minimize losses during transmission and maximize the utilization of the energy produced. While the grid can influence how electricity is generated and where it comes from, its core role revolves around the actual delivery to end-users. This capability is what makes an electrical grid vital to the functioning of modern society.
