1 Hydrokinetic Project Development Presented at the Alaska Rural Energy Conference, Fairbanks, AK April 29,2010 Monty Worthington, Director of Project Development

2 Ocean Renewable Power Company Overview Developer of technology and projects that convert river, tidal, and ocean currents into emission free electricity Founded in 2004 with executive offices in Portland, Maine and project offices in Anchorage, AK (ORPC Alaska, LLC) Eastport, Maine (ORPC Maine, LLC) Proprietary technology including OCGen, TidGen, and RivGen power systems Project sites in Cook Inlet and Nenana, AK, and Eastport, ME Beta Turbine Generator Unit (TGU) to be deployed late Feb,

3 Concurrent Project and Technology Development As an emerging and rapidly developing industry Marine Hydrokinetic (MHK) projects (Wind, Wave, River In Stream) concurrently develop technology and projects that will utilize these technologies Successful project and technology development are both critical for project success This concurrent development complicates permitting processes, existing permitting and regulatory practices can be inadequate to address uncertainties or irrelevant entirely 3

4 Permitting and Licensing Necessary Permits: Permitting process for hydrokinetic projects in the FERC Pilot Project License US is still being defined Environmental effects of MMPA Authorization technology are not understood These risks cannot be consistency Review measured without deployment Fish Habitat Permit of technology Fish Sampling permit FERC Pilot Project Licensing DNR submerged land use permit Process to deploy small scale, easily removable projects to gather this data is still being worked through to satisfy regulatory agency needs, with environmental monitoring to scale with the project size US Army Corps of Engineers Permit Coastal Zone Management Program Temporary Water Use or Water Rights Permit USCG Review MMS lease for OCS Projects 4

5 Project Development Process Select a site Perform preliminary resource assessment Secure site control Technology selection, development, and conceptual system design Site characterization and environmental studies Integrate t into permitting and licensing process Repeat previous three steps as necessary Finalize technology and system design Finalize permitting and licensing Install project and monitor technology performance and environmental effects 5

6 Technology Development the evolution of ORPC technology Proprietary TGU is the core of three hydrokinetic power systems TidGen Power System Bottom mounted TGU for shallow tidal applications Beta TGU OCGen Power System Floating OCGen Modules (stacked TGUs) for deep tidal and offshore ocean current applications RivGen Power System Bottom mounted TGU for remote river applications 6

7 Beta Turbine Generator Unit (TGU) Weight: 13 tons Design capacity: 60 kilowatts Steel and composite TGU support frame 14 feet tall Underwater Permanent Magnet Generator ADCF Turbine Visual Comparison TGU & 6 Tall Human

8 The Beta TGU mounted on the Energy Tide 2 Barge and Test Facility

10 Beta TGU project monitoring ORPC s is equipped with state of the art monitoring equipment to collect environmental and performance data for the project and to verify monitoring technologies and methodologies for this purpose Data collection equipment: Technical data including power, RPM, vibration, strain gauges etc for turbine performance evaluation 2 color and 2 B/W video cameras for monitoring of turbine and aquatic species interactions 2 DIDSONs and 2 Simrads for monitoring of aquatic species interactions with turbine Hydro-acoustic survey of noise source levels of TGU ADV, and flow meters to collect current velocity data Thermal sensors to measure heat transfer to water The ET2 control, data acquisition and monitoring room

11 TidGen Device initial deployment for Cook Inlet Tidgen TGU will be rated at kW in a 6 knot current TidGen TGU Will utilize (4) Beta sized turbines 8.5 ft dia. X 18 ft long each TidGen TGU will be 90 x 14 and 30 above the seafloor TidGen Devices and Bottom frame will weigh approximately 60 tons and will be separately installed TidGen Device footprint will consist of (4) 6 diameter feet. 11

12 Cook Inlet OCGen Module OCGen TM Modules will be attached to the seafloor via a compliant mooring system with screw type, gravity based, or driven anchors. Cook C k Inlet OCGen TM Modules will be comprised of 2 OCGen TM TGU s Cook Inlet OCGen TM Modules will be 90 x 28 rated between 400kW and 500kW. Modules will be deployed 40 below the surface to allow for navigational clearance 12

13 Cook Inlet Site Characterization Marine Geophysical surveys ADCP current velocity measurements Multi beam bathymetry Sidescan sonar Sub-bottom profiling magnetometer 13

14 Cook Inlet Environmental Studies Pre and Post deployment fish studies Pre and Post deployment Beluga monitoring Visual monitoring of proposed deployment area from 2009 through project deployment Passive acoustic monitoring from 2010 through project deployment Acoustic signature modeling and monitoring Modeling and monitoring effects on sediment transport 14

15 Planning Project compatibility with ih existing i Cook Inlet users Shipping Industry Port of Anchorage and Port MacKenzie Commercial fishing industry Marine service industry Energy industry Recreational Users 15

16 Power transmission system planning 16

17 Cook Inlet Project Licensing Process Initial FERC Preliminary Permit Secured in April 2007 FERC Draft Pilot License Application filed March 31, 2009 Second Preliminary Permit Applied for March 31, 2010 to allow more time to complete Final License Application FERC Final Pilot License Application to be filed in late 2010 or early 2011 All other permits and authorizations (USACE, ADNR, Coastal Zone Management, USCG, MMPA, etc) applied for before filing of Final License Application 17

18 Project Development Nenana RivGen Power Project and Hydrokinetic Test Center ORPC began working on the Nenana Project in early summer 2008, collaborating with the City of Nenana, the Nenana Native Council, The Alaska Center for Energy and Power, and the YRITWC to locate a suitable site for a Hydrokinetic Pilot Project and Test site. 18

19 The Nenana a Site on the Tanana a a River This site was chosen for its adequate current velocities, depth, lack of conflicting uses, accessibility, and community support for the location 19

20 Site Characterization Multibeam bathymetry to map the river bottom and establish baseline river channel location Acoustic Doppler Current Profiles (ADCP) to measure current velocities Side scan sonar to image the bottom for hazards to construction 20

21 Technology Development - RivGen Power System RivGen TGU will be rated at 30kW in a 6 knot current RivGen TGU is designed to fit into a standard 40x8 x10 CONEX container Power electronics will integrate RivGen into isolated microgrids id RivGen will be completely submerged allowing for potential year round operation 21

22 Addressing challenges through partnership p The Alaska Hydrokinetic Energy Research Center (AHERC) will be performing studies on the state of the art of riverine foundations and debris diversion systems to inform the ORPC engineering i team. AHERC will be collecting data on river debris to further inform design parameters for the RivGen TGU, debris diversion system, and foundation. AHERC will install a shallow water profiler (SWIP) to gather data on ice formation and breakup, and has also been collecting sub ice velocity data. Desktop and field studies on the potential impact of the project on local and migratory fish will be performed by UAF fisheries faculty and students. The effect of silt wear on ORPC turbine materials and components will be studied with UAA researchers The effect of the Project on sediment transport and riverbed migration will be monitored and modeled to ensure a sustainable approach to energy extraction 22
