What is the voltage range typically classified as transmission voltages?

Transmission voltages are typically classified in the range of 69kV to 765kV. This range is essential for efficiently transferring electricity over long distances from power plants to substations, where the voltage is then stepped down for distribution to consumers.

Higher voltage levels in this classification minimize energy losses that can occur due to the resistance of wires, making it possible to transmit large amounts of power more effectively and over longer distances. Operating in this voltage range supports the infrastructure needed for high-capacity transmission lines, ensuring that power can be transported reliably across vast geographic areas.

The other ranges mentioned do not align with the standard classifications for transmission voltages, as they either fall short of the necessary threshold or represent voltage levels more aligned with distribution systems rather than transmission. Therefore, option B accurately captures the voltage levels critical for transmission in the electrical grid.
