• Cook Inlet Tidal Energy Project:
• Fire Island Site - FERC Preliminary Permit in 2008
• East Foreland Site – FERC Preliminary permit in 2010, will

be ORPC’s first pilot project in Cook Inlet.

• RivGen Commercialization Project utilizing several test/

demonstration sites:

• Nikiski “Virtual River” test site
• FERC permitted site at Nenana on the Tanana River
• Kvichak River at Igiugig
• False Pass Ocean/Tidal energy feasibility study

Alaskan Tidal and River Hydrokinetic Projects

Project Development Work Completed:

• Acoustic Doppler Current

Profile Resource Assessment

• Complete Multi-beam

Bathymetry of Project Area

• Test deployment and

retrieval of Hydrophone for Passive Acoustic Monitoring

• f beluga whales, deployed

for overwinter deployment

• f two Hydrophones
• Identified potential come

ashore locations

• Completed REF Grant

Agreement with AEA

East Foreland Tidal Energy Project

Work Completed at East Foreland in 2011

• Circulation

modeling performed at UAA

• Stationary ADCP

survey attempted at 5 sites, data recovered from two sites

• Potential

interconnect sites have been identified

Multi-beam Bathymetry completed in June 2012

Utilized Directional Autonomous Seafloor Acoustic Recorders (DASARs) developed under Department of Energy (DOE) grant to ORPC to collect data on beluga whale and marine mammal use of the Fire Island and East Foreland Project areas

• Collected six months data at Fire

Island in winter 2010 - 2011

• Performed 1 month test

deployment of single DASAR to test deployment and recovery system at East Foreland in September

• Deployed two DASARs on

10/21/12 for overwinter period

Hyrdophone test and overwinter deployment

• DOE grant to ORPC is

funding flume studies at UAA to circulate high silt content water and test critical device components

• Testing several types
• f bearings/seals in

Cook Inlet water samples

• Will determine best

suited bearing/seals and maintenance cycles

UAA Suspended Sediment Flume

RivGen™ Power System – Built for remote Alaskan conditions

RivGen™ Pontoon Support Structure

• Built and tested in Alaska
• Fabricated and assembled by Marsh

Creek in Wasilla

• Tested at the Nikiski “virtual river”

test site adjacent to the Arctic Slope Regional Corp Rig Tenders Dock

• Verified pontoon support structure

functionality

• Will complete additional testing in

fall 2012 and spring of 2013

ORPC was contracted by the Aleutian Pribilof Islands Association (APIA) to complete a tidal and ocean current resource

• assessment. ORPC worked

with APICDA, Benthic GeoScience, NREL, and TerraSond to complete the survey this fall

False Pass Reconnaissance study – ADCP survey

12

Reconnaissance of 7 sites in the vicinity of False Pass performed to assess viability to deploy ADCP equipment at each site

Hazard Assessment

13

• One ADCP under loan from

NREL at northern site offshore

• f False Pass Harbor
• Second ADCP at southern site

in narrow constriction of Isanotski Strait

• Both ADPCs deployed with

redundant recovery systems to enhance recovery probability in harsh high current environment

• Programmed to collect data

for full lunar cycle (29.5 days)

• Two HOBO water level sensors

also deployed North and South of False Pass to enhance UAA model fidelity

Two ADCP’s deployed late September- early October

14

ADCP’s recovered in late October - early November

Unusual Marine mammal siting… Some near misses… Success at last! Challenging early winter weather conditions…

15

• Continue to pursue additional funding with application to Round 6 of the

REF for funding for the TidGen™ Array Project at East Foreland

• Additional field work in 2013 field season including continued Acoustic

Monitoring, ADCP surveys, and geotechnical work.

• Working with HEA on economic analysis of valuation of power produced

from the project

• Working to submit Federal Regulatory Commission (FERC) Final License

Application by January 2014 to be prepared for installation of first test device in July 2014

• Awarded Emerging Energy Technology Fund (EETF) grant from AEA and the

Denali Commission to test RivGen™ device at Nikiski in 2013 and perform Demonstration project at Igiugig in 2014

• Analyze data for False Pass Survey and perform economic analysis of

potential for tidal/ocean current energy with APIA

Continued Project Development work 2012-2013
