OSTI ID:5492405

A study was made of the feasibility and economics of interconnecting a number of communities in Southeast Alaska utilizing dc submarine cables. The objective is to make it possible to utilize the hydroelectric power that is available in some areas to minimize fossil fuel generation in other areas and to supply hydroelectric power to a potential large mining load in eastern Southeast Alaska. A reconnaissance inspection was made of possible transmission line and cable routes and terminal sites. The first part of the work included a review of the load/resource analysis to determine whether the system configurations and capacities proposed by APA were engineeringly appropriate. Other items addressed included the suitability of dc transmission for this application, multiterminal aspects of dc transmission, performance of the dc system, reliability and operational flexibility of the system and operation and maintenance. Results are presented in a separate report. The second part of the work consisted of the costing of the transmission schemes and recommendations on the future activities that should be carried out for detailed cost estimates and designs prior to preparation of bid specifications. These aspects are described in detail in this report.
