The main benefits of using high-voltage transmission include:

• Reduced Power Loss: As explained above, higher voltage reduces the current, which in turn dramatically minimizes energy loss from resistance along the transmission lines.

• Cost Efficiency: Lower current allows for the use of thinner and lighter conductors and smaller transmission towers, which significantly reduces the cost of materials and infrastructure for long-distance projects.

• Improved Voltage Stability: High-voltage systems maintain a more stable voltage level throughout the line, ensuring that the power delivered to end-users is consistent and reliable.

• Increased Capacity: Higher voltage allows for the transmission of more power through the same conductors, increasing the overall capacity of the grid without adding new lines.
