1 The Northwest National Marine Renewable Energy Center Meleah Ashford, Program Manager Oregon State University

2 Northwest National Marine Renewable Energy Center One of two national marine renewable energy centers in the US NNMREC is a partnership between Oregon State University (wave energy) University of Washington (tidal energy) National Renewable Energy Laboratory 14 co-investigator faculty from OSU & UW

3 NNMREC Vision Improved understanding of marine renewable energy (MRE) system performance and interactions for optimization opportunities. Development of the necessary infrastructure to test and deploy MRE systems. Contributions to national and international marine energy performance, survivability, and environmental assessment standards. Assessment of effects of in-water systems in an environmental and social context.

4 NNMREC Funding and Timelines Total Original Funding = $13M with matching funds USDOE-Energy Efficiency & Renewable Energy $1.25M annually for 5 years NNMREC Matching Funds Oregon Legislature ($3M for capital projects (Test Berth)) Oregon Wave Energy Trust Oregon State University University of Washington (Snohomish PUD, BioSonic, EPRI) New Federal Appropriations (FY09) $2.3M for test berth acceleration and research

5 Focus Is Performance Evaluation, Research And Outreach Marine Renewables Research Technology Environmental (physical and ecological) Social Public Outreach/Engagement & Information Clearinghouse Marine Renewables Testing Facilities Wave Energy Devices (OSU) Tidal Energy Devices (UW)

6 Marine Renewables Research - Technology System Performance Assessment through Modeling and Simulation Materials Research for Reliability and Survivability Mobile Test Berths for Performance Assessment of Wave Energy Systems Mobile Instrumentation Package for Performance Assessment of Tidal Energy Systems

7 Device and Array Optimization Assemble a nearshore wave model using simplified representation for wave energy conversion (WEC)device Wave height in the vicinity of an idealized array

8 Marine Renewables Research - Physical Environment Physical Environment Prediction & Monitoring Effects of Wave Energy Systems on the Wave Climate & Potential Impact on the Coastline Impact of Tidal Energy Systems on Estuaries

9 Compatibility with Environment w/o array w/ array Wave model to transform affected wave field to shore Wave height near a beach

10 Marine Renewables Research Ecological Learn from experience of hydro and wind energy Effects of Electromagnetic Fields Effects from construction/deployment/service of cables Effects of the physical structures Monitoring needs to be scale appropriate Need devices in the water to assess impact

11 Marine Renewables Research - Social Aspects Effects on fishing community Effects on local economic issues Benefits Impacts Educating public for more informed community and political decision making

17 1 st Stage Demonstration Center Test Berth - Planned

18 Future NNMREC Demonstration Site

19 NNMREC Wave Energy Test Berth Timeline (Estimated) PHASE I. One Floating Test Berth (1 MW) funded II. Up to four more Floating Test Berths (1 MW ea.) III. Central Junction Box funded IV. Grid-connected Test Berth (incl. subsea cable to shore, substation interconnect, land-based facilities at HMSC for data analysis, communications and control) V. Demonstration Site (generating up to 5 MW)

20 Test Berth Siting Process Initial focus on point absorbers (buoy-type devices) Site criteria Minimum criteria 140-foot depth (200-foot maximum) Soft/sandy bottom 1 X 1 mile footprint (not including buffer zone) Preferred Criteria miles from shore Low marine traffic area High visibility to boating traffic Close proximity to Yaquina Bay Unobstructed wave conditions (e.g. no reef shadowing) Good access for salvage equipment Close proximity to grid connections for future Ability to bore cable from site to shore fro future grid connection

21 Environmental Clearances, Permits and Consultations US DOE required third-party NEPA documentation for funding of test berth beginning soon Oregon Department State Lands (DSL) Oregon DEQ Oregon Coastal Management Program Oregon Department of fish & Wildlife US Coast Guard NMFS Federal Energy Regulatory Energy Commission (FERC) Mineral Management Service (MMS) US Fish & Wildlife Service US Corps of Engineers
