Senator Murkowski introduces bills to boost hydropower generation

Understanding Energy Transmission - ET 101

Despite the length of transmission lines, by tradition, much of the energy produced in a region stays within or near that region. There are exceptions, but they won't be discussed at this point. For example when Alaska interconnects to British Columbia, most of the newer energy won't travel much farther than to the nearest load in British Columbia.

When new generation is added, the energy is actually shifted to the next region's load in a kind of domino effect. So the power may leave the region, but it doesn't go too far.
