Transmission is good.
Seems simple enough.
Rob Gramlich, Pres. of Grid Strategies LLC:
They Knew it in 1934.
“Experience indicates that marked economies are effected when interconnecting transmission lines are built to tie all generating units and all the consumers of a wide area into one circuit. Without such lines, each generating unit and its market are isolated. The generating unit must provide for a peak load which is much higher than the average load.
The interconnecting of many markets and many generating units makes it possible for the peak loads in different uses to offset one another in the course of 24 hours, so that the maximum peak load can be brought much nearer to total generating capacity than in the isolated unit
The total investment required for a given standard of service is thus greatly reduced by interconnection, and with the investment the necessary charge to con- sumers is also reduced.”
