UAF 11-0017: NENANA, ALASKA HYDROKINETIC (RIVGEN™) POWER SYSTEM
Progress Report: FY 2010, 3rd Quarter Submitted October 15, 2010
1. Total Project Funding Denali Commission $830,325 ORPC Alaska $1,128,449 2. Updated schedule and milestone information as identified in the Project Work Plan.
• AHERC foundation and debris diversion literature surveys, data collection and final reports completed Dec 31, 2010
AHERC will complete its literature surveys on best practices for riverine foundation systems and the state of the art of debris diversion systems. The foundation study will pay special attention to applicability to Alaskan River environments and deployability with available infrastructure in mind. The debris diversion study will focus on debris diversion concepts that are adaptable to in river hydrokinetics and will incorporate reports on the data collection efforts performed during the 2010 field season. As there will be a late start to the field season this year as funds will not be available until August 2010 some of the debris data collection efforts may be shifted to take place as part of the foundation system deployment in 2011.
• ORPC environmental and site characterization data collection for project design and FERC draft license application performed by October 1, 2010
ORPC will complete the data collection efforts necessary for choosing optimal locations for RivGen™ deployments based on bathymetry and current velocity measurements. ORPC will also complete data collection at sites of interest to quantify the river bed substrate to allow for the completion of foundation support frame design.
• Prototype Bottom Support Frame And Debris Diversion system fabricated, deployed, tested, and retrieved at Nenana Site July – September 2011
Prototype bottom support frames and debris diversion systems will be designed by ORPC engineers based on AHERC literature surveys and data collection efforts. These system components will be fabricated in the 2nd Quarter 2011 for deployment and testing in the 3rd Quarter 2011. The testing will include verifying the efficacy of deployment and retrieval procedures as well as testing the persistence of the foundation system and debris diversion system in the Tanana River. Additional data collection will be undertaken by ACEP to further the quantification of debris loading and impact energy on the foundation and debris diversion systems.
• Additional field work required for Final Pilot License Application completed by Oct 31, 2011
Any additional field work required for prudent project implementation and completion of successful permitting for the project will be completed in the 2nd and 3rd quarters 2011. This additional work will be scoped as required by project engineering data needs and resource agency consultations.

• FERC Final License Application submitted by Dec 31, 2011
After agency review of ORPC’s Draft Pilot License Application for the Project, ORPC will submit the FERC Final Pilot License Application allowing the recommended six month lead time for FERC and Agency approval to issue ORPC a Pilot License to interconnect the RivGen™ Power System to the GVEA grid in June 2012
• RivGen™ TGU built and tested at Eastport Maine test site by Dec 31, 2011
ORPC will complete the fabrication of the RivGen™ TGU including the turbines, support frame, and generator. This system will be tested aboard ORPC’s state of the art Energy Tide 2 test facility in Cobscook Bay, Maine to verify that the turbine meets power output and performance specifications prior to its shipment to Alaska.
• Final Report on Nenana site characterization work and foundation system and debris diversion system performance submitted to ACEP by Dec 31 2011
ORPC will submit its final report on the performance of the foundation system and debris diversion system with input from AHERC data collection efforts to ACEP for inclusion in ACEPs final report on the project.
• Final performance report on RivGen™ test in Maine submitted to ACEP by Feb 15, 2012
ORPC will submit a final performance report on the RivGen™ TGU test in Maine for inclusion in ACEP’s final report on the project.
3. Narrative Summary As ORPC Alaska (ORPC) and Alaska Center for Energy and Power (ACEP) were finalizing contract documents until September 10, 2010, some of the work scheduled for this quarter was delayed. This includes, specifically, AHERC’s plan to collect data on debris in the Tanana River, which will now be re-scoped and rescheduled to take place in summer 2011. ORPC, however, has moved forward with site characterization efforts employing TerraSond Ltd to perform a detailed bathymetry and ADCP transects to measure current velocity in the area of the Tanana River now being considered as the prime location for the RivGen™ deployment. Although the ACEP contract was not fully executed, ORPC approved this work on the assumption that EETG funding would be available to reimburse this cost near the time of its billing to ORPC. To economize on field mobilization, this effort was undertaken in conjunction with work performed for AHERC by TerraSond as part of AHERC’s AEA funded project to characterize the reach of river being investigated for the RivGen™ Power Project. TerraSond performed this work in early August 2010 and issued a preliminary representation of the data to ORPC and AHERC. This has been included as Appendix A. Considering this new data ORPC, AHERC and TerraSond came to an agreement on the area to focus TerraSond’s second expedition in early October 2010. The purpose of this expedition is to characterize the sub-bottom profile of the proposed deployment area to inform AHERC’s foundation literature survey, and ORPC’s subsequent bottom support frame design and engineering. Based on this recommendation, Monty Worthington, ORPC Project Director, travelled to Nenana on October 1, 2010 and met with the City of Nenana, the Nenana Native Council, and Inland Barge representatives to confirm that the new site would not create any conflicts with existing uses. Details of this meeting and TerraSond’s October expedition will be included in the next quarterly report.

Despite the delay in debris data collection in the Tanana River by AHERC, ORPC anticipates being able to maintain the schedule as proposed in the grant documents, with the possible exception of a delay in the construction of prototype debris diversion device, as this may be dependent on initial data on debris distribution, size, and frequency for a prudent design to be completed. The project remains on budget. The only costs incurred have been the work contracted to TerraSond for the August expedition to Nenana.
