Solar Regional Test Center in Vermont Achieves Milestone Installation

The solar industry is now more than 60% of the way toward achieving the DOE SunShot Initiative affordability goal of $0.06 per kilowatt-hour for solar electricity. Meeting the last 40% without compromising quality will be challenging. To help US industry demonstrate and validate that new PV technologies can consistently perform over time, the DOE —in […]

Measuring Inflow and Wake Flow Turbulence Using a Mobile-Deployed Acoustic Doppler Velocimeter

Sandia has developed a mobile acoustic Doppler velocimeter (ADV) system that characterizes inflow and wake flow velocity and turbulence around a vertical axis turbine deployed at the Roza Canal, Yakima, Washington. The ADV was mounted on a hydrofoil (see figure, left-hand panel) and deployed using either an aluminum platform mounted on a bridge (center panel) […]

Continuous Reliability Enhancement for Wind (CREW): Project Update

During 2013, the CREW team performed an internal reassessment of their effort to identify the benchmark’s value, any data gaps, and opportunities to be better aligned with the wind industry and found that wind-plant owners and operators have been developing in-house reliability-data collection tools with similar goals to the CREW project and that the original […]

Investigating the Value of Simulated Wind Data for Wave Resource Characterization at US Test Sites

Sandia is cataloging wind, surface current, and wave data at US test sites to provide detailed and consistent wave-resource data that wave-energy developers can use to evaluate and compare different test sites. As part of this effort, Sandia compared National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) simulations for wind speed and […]

Quantifying Offshore Wind Scour with Sandia’s Environmental Fluid Dynamics Code (SNL-­‐EFDC)

A key risk driver in offshore wind projects is the potentially detrimental interaction between offshore wind substructures/cables and the seafloor. In previous years, Sandia developed methods for evaluating regional sediment stability with the use of combined wave, circulation, and sediment dynamics modeling. Knowledge of sediment stability—not only in the vicinity of an offshore wind deployment, […]
