The Hawaii geothermal/interisland transmission project

In May 1989, Hawaiian Electric Company, the electric utility serving Honolulu and the island of Oahu, issued a request for proposal for the purchase of electricity produced from geothermal resources on the island of Hawaii and transmitted by a combination of overhead lines and submarine cables to Oahu. The authors describe the project, with attention given to the AC and DC transmission portion. A brief summary of the proposal process and evaluation results is also provided.<>
