What are the advantages of 765 kV?
Larger capacity lines allow for greater flow of electricity from generation plants in a broader area. This means low-cost generators in a much broader area can actually compete head-to-head, providing access to lower cost generation to customers currently isolated from it. Additionally, an expanded 765 kV network will increase opportunities for green power, such as wind farms located in remote areas far removed from load centers. From a siting standpoint, 765 kV is much more efficient in terms of economies of scale and right-of-way than lower capacity lines. A 765 kV line requires a much narrower right-of-way than multiple smaller lines needed to transmit the same amount of power.
