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.

Recommendation for Executive Action

  1. Status: Closed

    Comments: Please call 202/512-6100 for additional information.

    Recommendation: The Federal Power Commission should: take the lead in promoting joint Federal-industry studies to identify and evaluate new interconnections and changes in existing interconnections; follow up on completed studies to resolve objections which might frustrate the adoption of study recommendations; work with utilities to establish criteria for interconnection studies which will adequately consider national goals and identify factors which may adversely affect proposed interconnections; and work with utilities to make sure that they use the criteria in both industry and Federal studies.
