Abstract: The HDWC Program is determining the technical and economic feasibility of electrically interconnecting the islands of Hawaii, Maui, and Oahu with a high voltage direct current submarine cable system. To investigate system feasibility, it has been necessary to "design," at least conceptually, a system capable of meeting all of the technical requirements of a full-scale link while at the same time, attempting to optimize the economics. A major research area has been the system configuration because of the great impact of the hardware on system cost. One element of system configuration is the method of completing the electrical circuit, i.e., the "return" of electrons to the source. The return may be through another cable or through the ground and/or sea. Selection of the method of return is influenced by system polarity which, in turn, determines the return current magnitude; potential environmental impacts associated with the method of return and return current magnitude; impact on system reliability; and, impact on system capital and operating costs. The present report examines the environmental consequences of selection of a "sea return" for the Hawaii interisland electrical cable system. The sections below describe the options for system polarity, the selected design for Hawaii, the characteristics of sea electrodes, their environmental impacts and possible mitigation measures.
