Columbia Power LCOE (levelized cost of energy) Model for the Stingray H1 at the DOE Reference Site of Humboldt, CA. The model is integrated with and reports LCOE from DOE Cost Breakdown Structure

This is the LCOE analysis spreadsheet and content model for the heaving point absorber buoy developed for controls purposes. The cost assessment was done on a wave-farm of 100-units.

The overall project objective is to materially decrease the leveled cost of energy (LCOE) of the Columbia Power (CPower) StingRAY utility-scale wave energy converter (WEC). This will be achieved by reducing structural material and manufacturing costs and increasing energy output. In this Project, improving the overall Power-to-Weight ratio (PWR) is accomplished through lowering design margins?allowing for weight reduction and more efficient, cost-effective WEC manufacturing and assembly?and by optimizing mass-related WEC performance parameters, such as center of gravity and system inertia. A mixed materials approach to further structural optimization was developed under this Project and validated with extensive laboratory structural testing. This approach substitutes fiber-reinforced plastic (FRP) for steel where appropriate. The benefits of steel are maintained where most useful, for instance at structural joints where the stiffness of steel is required, and the complex geometry is more readily fabricated with steel. However, there are structural spans whose simple shapes are readily fabricated with mandrel-wound FRP and where significant cost and weight savings can be found. An adhesive, double lap shear joint is used to join the FRP and steel subcomponents.

This dataset presents techno-economic modeling results for the AquaHarmonics Wave Energy Converter (WEC), analyzing both baseline and optimized system configurations using the National Renewable Energy Laboratory's System Advisor Model (SAM). The models incorporate empirical performance data and simulate deployment at the PacWave South test site off the coast of Newport, Oregon. Included are SAM-generated reports and a project file detailing device and array specifications, energy production estimates, capital and operational costs, and resulting Levelized Cost of Energy (LCOE) calculations. The data provides comparative insights into design improvements and their impact on system performance and cost. SAM software is required to view and interact with the project file, and can be downloaded via the attached link.

Spreadsheet which provides estimates of reductions in Levelized Cost of Energy for a surge-mode wave energy converter (WEC). This is made available via adoption of the advanced control strategies developed during this research effort.

Project resultant levelized cost of energy (LCOE) model after implementation of model predictive control (MPC) controller. Contains annual energy production (AEP) data, cost breakdown structure (CBS), model documentation, and the LCOE content model. This is meant for comparison with this project's baseline LCOE model.

This submission contains two resources developed by Booz Allen Hamilton Inc. in 2025 for the U.S. Department of Energy/Water Power Technologies Office (WPTO). The study identifies near-term opportunities to reduce costs and improve performance in wave and tidal current energy systems. Conducted in 2025, the work combines a literature review with insights from approximately 140 publicly available resources and 13 subject matter experts from five national and international organizations, to develop and recommend four potential approaches to advance marine energy technologies. The analysis focuses on the primary cost and performance drivers for marine energy technologies including power, structural design and device profile, anchoring and mooring, operations and maintenance, and array design, and uses DOE's standardized cost breakdown structure to assess their impact on the levelized cost of energy (LCOE). The material presented in the final report and presentation are intended to clarify, guide, and inform the research and development (R&D) of commercially viable marine energy systems.
