In a process similar to that of any commodity, energy is a product that needs to be carried from the place of its production to its end user. Therefore, it must leave the - hydro, wind, nuclear, thermal or solar power plants to be transmitted to the cities, industries, rural areas and other locations of consumption.
After being generated in power plants, the energy is then conducted by transmission lines of electrical interconnection companies such as ISA CTEEP to the substations and power distribution grids.
Substations, transmission lines are connected so that the energy can travel towards different locations. In this way, the electricity - which is high voltage - goes through transformers, making it low voltage, that is, ready for domestic use. After getting to the cities, the distribution grids are responsible for bringing electricity to homes, schools, hospitals, industries, etc.
