What are "transmission losses" in an electrical grid?

Transmission losses refer specifically to the electrical energy that diminishes or is lost as it travels through transmission lines from power plants to end users. This loss occurs mainly due to the resistance present in conductors, which converts some of the electrical energy into heat, along with other factors such as line capacitance and leakage.

Understanding transmission losses is essential for grid efficiency, as they represent a significant portion of total energy wastage in the grid system. By focusing on reducing these losses through better materials, improved technologies, and more efficient system designs, operators can enhance the reliability and sustainability of the electrical grid.

The other options describe concepts that are related to energy production, consumption, or surplus but do not address the losses that occur specifically during the transmission of electricity through the grid.
