What is the minimum connected load per mile for a 500kV/765 kV line that is energized?

The minimum connected load per mile for a 500 kV/765 kV line that is energized is crucial for ensuring that the transmission system is efficiently utilized and that power losses are minimized. The value selected, which is 20 MW, reflects the industry standards and operational practices for high voltage transmission lines.

Transmission lines of this caliber are designed to handle large amounts of electricity, and having a minimum connected load ensures that the line is not underutilized. Underutilization can lead to inefficiencies such as increased losses and lower reliability of the system. By establishing a minimum connected load, it becomes easier to maintain stable voltage levels, ensure the integrity of power delivery, and optimize the asset's performance.

Lines operating at such high voltages typically support significant loads, and adherence to the specified minimum helps in justifying the infrastructure investment made in constructing these lines. Thus, the established minimum connected load of 20 MW aligns with technical assessments and operational guidelines in the energy transmission sector, indicating optimal functioning and stability for the systems involved.
