The ocean energy sector, particularly ocean wave and tidal current technologies, have seen increased research, development, and demonstration activity around the globe. The Pacific Northwest (PNW) coastal regions in North America, have a vast theoretical potential for ocean power utilization. This region is also promoting a number of far-reaching initiatives. This report discussed a project that determined the practical level of energy development from wave and tidal current resources that could contribute to the near-term and longer-term regional electricity needs through electrical systems scenario analysis. Specifically, the study reviewed the state of the technologies, grid integration issues, interconnection standards, and resource potentials pertaining to ocean energy development in Oregon, Washington, and British Columbia. The purpose of the project was to assist regional utilities and government policy makers in developing appropriate policies to advance relevant technologies and deploy ocean energy plants in the PNW. A secondary goal of the project was to develop a preliminary interconnection guideline for electrical utilities in Oregon, Washington and British Columbia. System scenario analysis was conducted through case studies to quantify the resource potentials and network enhancement needs. Forecasted load growth and resource expansion plans at various time horizons would also add further strength to these investigations. The report reviewed the potential differences and opportunities associated with integration of ocean wave and tidal current energy plants to PNW electrical girds, in comparison to wind energy. It also presented a review of relevant geographical areas in the PNW regions and recommendation of target areas for consideration of scenario analysis, and establishment of a network scenario team.
