According to Federal and independent power studies, future reliability and adequacy of the electric power supply depend on the timely installation of generating and transmitting facilities to meet our future needs.

Data from utilities, utility power pools, and national organizations show that the present interconnections of utilities were sufficient at the time of the study to meet power needs in emergencies, but higher capacity transmission lines to interconnect utility systems will be required to carry the growing electric loads projected through the year 2000. Federal studies of interconnections conducted from 1969 to 1975 for the most part were based on costs and benefits for the interconnecting utilities; were aimed at systems in the Southwest and concentrated on small isolated systems; and were done without involving the affected utilities.
