Why Cook Inlet? • 4 th largest tidal range in the world up to 12 meters (40 feet) Current velocities up to 10 knots Tidal resource is in the vicinity of electrical infrastructure - the Railbelt Grid Staggered tidal phases can lead to continuous power production Univ. of Alaska-Anchorage Modeling 5 18
Cook Inlet Tidal Current Phases 6 6
ORPC Alaska’s Cook Inlet project sites • Began Project in northern Cook Inlet 2007, narrowed focus to Fire Island in 2009 • Began East Foreland Project in 2010, now the priority Pilot Project site 7 7

Cook Inlet Environmental Studies Pre and post deployment fish studies Pre and post deployment Beluga monitoring • Visual monitoring • Passive Acoustic Monitoring Sediment transport modeling • Working with UAA researchers to develop modeling and study plan 11 11
Passive Hydroacoustic Monitoring • ORPC Project, DOE funded • Directional Autonomous Seafloor Acoustic Recorders (DASARs) - localize beluga vocalizations • Team CIBA collaboration (ADF&G, NMML, UAF, UH) • Ecological Acoustic Recorder (EAR) and C- POD • used by Team Cook Inlet Beluga Acoustics Whale photo credit: NMFS, AK regional office 12 12
East Foreland, Alaska Tidal Energy Project 13 16
Work Completed at East Foreland in 2011 • Circulation modeling performed at UAA • Stationary ADCP survey for full lunar cycle performed at five locations Have two weeks of data from • one site • 2 ADCPs yet to be recovered. They contain more than six weeks of data. • Potential interconnect sites have been identified. • Collaborating with HEA on project development • UAA flume work continues. 14 17
ADCP Data from Northernmost Site 15 19
Work Planned for 2011-2012 at East Foreland • Recover ADCPs and analyze data • Do additional modeling calibration at UAA with ADCP data • Work with NOAA/AEA on modeling effort and provide input on ADCP locations for spring 2012 deployment at 10 sites • Scope and initiate environmental studies including beluga monitoring and pre-deployment fish studies • Collect geophysical and geotechnical data using multi-beam and side scan sonar, sub-bottom profiler, magnetometer etc. • Test RivGen™ bottom support frame at Nikiski and initiate local contractor relationships through this work • Work with HEA towards Power Sales Agreement • Submit FERC Draft Pilot License Application 16 22
