  4. Overview • Resource and design info needs are wide ranging and include weather, wind, waves, currents and geophysical • Implications for structural design, project layout, performance, project access & availability, etc. • Measurements & modeling are both needed • Extremes and fatigue are both important • Extreme load analysis must consider operating characteristics of turbine, not just joint probability distributions of external events (i.e., wind & waves) Source: NREL

  5. Interagency Partnerships

  6. Key Input for Public/Private Data Campaign • Design Standards • IEC 61400-3 Part 3 (Offshore Wind turbines) • RADC Workshop, Washington D.C. June 2011 • Experts input from industry, national labs and other agencies • Gaps Analysis near complete • Next: Develop roadmap to address gaps

  7. Gaps Analysis: Summary of Gaps • Wind Energy • Long-term frequency distributions near surface • Long-term observations at hub height • In-situ measurements at hub height • Vertical wind profiles • Downstream wind speeds at hub heights (i.e. wake effects) • Turbulence intensity at hub height • Marine Hydrokinetic (MHK) Energy • Current velocity distributions • Wave climatologies • Long-term subsurface turbulence observations • Long-term current shear observations • Across both technologies • Wind/Wave coupling • Wind speed/wave height distributions • Wind direction/wave height distributions • Extreme events • Ice, lightning, hurricanes, earthquakes Resource Assessment http://cleantechnica-com.wpengine.netdna-cdn.com/files/2008/04/towerjpg1.jpeg Measurement Modeling Resource Assessment Historical Referencing

  8. Ocean Observation Challenges • Current ocean observation systems focus on a few meters above the sea surface to the ocean floor • Very few measurements currently taken at heights needed for wind technology • Technology improvements for ocean observation systems • What technologies can we began designing/employing now to gather data that will be needed in the future? • Frequency distributions needed require long-term observations • Methods needed for confident extrapolation of available data sources to address needs in nearer term • Define longer-term data and observations needed • Spatial distribution of observations • How should we deploy ocean observation systems spatially to gather information across a broader region?

  16. Resource Assessments Underway Goals for Resource Assessments • Determine maximum extractable energy (theoretical limit) • Calculate technically extractable energy • Characterize seasonal variability of resources • Display results in GIS formatted database • Wave: EPRI, end of FY 2008 • Tidal: Georgia Tech, end of FY 2008 • Ocean Current: Georgia Tech, end of FY 2009 • Ocean Thermal: Lockheed Martin, end of FY 2009 Marine Resource Assessment Awards:

  17. Wave Resource Assessment Wave Energy is the dominant MHK resource available to the United States ≈ 900+ GW (≈ 9+ Quads or 2,640 TWh/year) Physical Potential ≈ 400 GW (≈ 4 Quads or 1,170 TWh/year) Extractable

  18. Tidal Resource Assessment CONUS tidal resources are concentrated and exist in close proximity to major coastal load centers… However, over 90% of the overall resource is located in Alaska. Tidal power can likely provide less than 1 Quad (≈ 293 TWh/year) of energy annually
