Abstract
This document summarizes existing Marine and Hydrokinetic (MHK) performance metrics known to the United States Department of Energy and national laboratories. This document was updated based on feedback from the MHK Energy community, however, this summary still may not be exhaustive. There are a wide variety of needs and uses for metrics. All stakeholders, such as developers, funding agencies, investors, and researchers, have a need for metrics and their many uses. It is evident that the sector will benefit from clear techno economic performance metrics to guide development towards success. There are international efforts underway to bring the community together to (1) understand what metrics/approaches are being used currently and (2) reach a global framework on the approach to the measurement of success. This document serves to list existing metrics known to the U.S. at the present, and is not meant to represent international efforts or consensus.
