The Grantee is responsible for identifying any other sources of project funds and for ensuring compliance with applicable wage scales for all sources of project funding.If a Grantee believes they or their contractors may be exempt from these requirements,they should contact the State of Alaska Department of Labor and Workforce Development,Wage and Hour Administration,for a determination and forward a copy of that determination to the Authority's Grant Administrator. 14,Construction Plans and Specifications Review Prior to public notice of bidding a construction project the Grantee will provide the plans and specifications to the Authority for review.Concurrence that the plans and specifications are consistent with the grant award must be received before grant funds will be released for construction related costs. 15.Construction Insurance and Bonding When the value of the construction is anticipated to be greater than $100,000,prior to beginning construction on a project funded by this grant,the Grantee or grantee's contractor(s)must provide the Authority;1)proof of adequate insurance as defined in Appendix B.#4 of the grant agreement,and 2)either a payment and performance bond,as may be required by AS 36.25.010,a surety in form and substance acceptable to the Authority,or some other guarantee or assurance acceptable to the Authority that the Grantee or the Grantee's contractor has the capacity,qualifications,and financial resources necessary to complete construction of the project as proposed in the grant or construction contract(s)funded by this grant. Page 13 of 39 Advanced Grid Solutions Strategy Grant Agreement #7310302 |Appendix C_Grantee Proposal/Scope of work This grant consists of $210,750 from Round 3 of the Emerging Energy Technology Fund and a match of the same amount from the grantee and other cooperating entities to develop an advanced grid integration strategy that will enable multiple renewable energy sources incorporated with an Energy Storage System (ESS)to be delivered to remote diesel microgrids at high penetration,including stand-alone,diesel off operations.The primary innovations of this system will include development and validation of an inverter capable of operation in both grid- support and grid-forming (current source and impedance controlled voltage source)modes and software to optimize dispatch of energy to maximize efficiency and enable standalone operations.Using shared components and integration strategies across multiple renewable energy sources will simplify power integration and enhance economics and replicability.This Project will culminate in the demonstration of this technology by integrating hydrokinetic power from ORPC's RivGen®Power System simultaneously with power from a wind turbine array installed by University of Alaska Anchorage (UAA)along with ESS into the grid of the Village of Igiugig,Alaska. The proposed microgrid architecture will share common power conditioning technology components to integrate renewable energy power from both wind and hydrokinetic energy into the Igiugig grid with the incorporation of ESS and a novel control technique.This system will enable high penetration for these renewable energy resources with up to full 100%penetration with diesel generation turned off,and added reliability and availability of stand-alone renewable source operations due to the inclusion of energy storage.This architecture will use an inverter being developed by Intergrid that accepts DC power on the front end from variable frequency drives (VFDs)which actively rectify and maximize power from each of the wind and hydrokinetic turbines.The inverter is capable of active grid-forming.Short-term energy storage will also be integrated on the DC bus for the wind.The technology developed as part of this Project will be tested in a methodical fashion to reduce risk and increase efficiency and understanding of the testing process.As such,the demonstration phase will be split into two distinct parts:laboratory testing and field testing. The laboratory testing will take place at both Intergrid and National Renewable Energy Laboratory (NREL)facilities and will include demonstration of the low cost electrical dispatch software developed as part of this Project,as well as the advanced modular inverter design. The goals of the demonstration will be to prove the functionality of the major Project innovations and insure that they are ready for full-scale field implementation.During the laboratory test stage the subsystems will undergo a pre-defined test schedule with specific pass/fail test criteria developed as part of the Project and submitted as a deliverable prior to actual testing.Following bench testing of the inverter system and dispatch software at Intergrid's test facility,a laboratory hardware-in-the-loop (HIL)test will take place at NREL.For the HIL stage of the lab testing multiple rectified 3-phase AC power sources,including a RivGen®generator,will be connected to the Intergrid inverter and in turn to a 3-phase AC load.The dispatching and monitoring of the power conversion chain will be controlled by the dispatch software. Upon successful completion of the laboratory testing phase,the components will be demonstrated in the field.Field demonstrations will take place at Igiugig,Alaska,under the guidance of local Project partners Igiugig Village Council (IVC).In 2015,ORPC completed a three-month installation of a single prototype RivGen®Power System.During that demonstration,the prototype RivGen®device was installed with the knowledge that it would never be capable of providing the entire village load and as such used an inverter that was grid- Page 14 of 39 Advanced Grid Solutions Strategy Grant Agreement #7310302 supporting,i.e.,requiring and existing voltage and frequency to match.However,the prototype RivGen®Power System consistently provided approximately one third of the village's electrical load and periodically reached penetration thresholds of one half of the village load.As the RivGen®technology improves,and with the inclusion of additional renewable power sources, the need for an inverter which can act as a grid-forming inverter becomes necessary. In order to validate the full-scale functionality of a power system that includes ESS and grid- forming inverters,three particular operating conditions will be proven during field testing:1) grid-forming functionality of inverter;2)grid-supporting functionality of inverter;and 3)transition to and from generator parallel. The overall project objective is to develop a multi-use inverter building block that can be used to interface rotating machines and storage to a village microgrid,and control software that performs optimum dispatch and fault response for the microgrid.From an economic perspective,the objective is to develop a commercial inverter with dispatch system that can be deployed for less than $0.25/W.Specific project objectives include the following:1)completion of modeling as a basis for contro!and dispatch software design;2)laboratory validation of RivGen®generator,VFD,and Intergrid inverter integration at NWTC;3)laboratory validation of supply of power from Intergrid inverter to diesel microgrid at ESIF;4)integration of power from the wind turbine(s)to the Igiugig grid using prototype Intergrid Inverter;5)integration of power from the RivGen®Power System to the Igiugig grid;6)integration of power from the RivGen® device and wind turbine(s)simultaneously to the Igiugig grid;7)integration of energy storage; and 8)demonstration of control and dispatch software operation;and 9)final report.

FNSB will be demonstrating a commercially available gasification CHP unit at either the Big Dipper Ice Arena or Hamme Pool in Fairbanks.Working with ACEP they will demonstrate the microgrid capabilities of the unit as well.The focus on the project is the operations and maintenance requirements and overall system capabilities. ORPC received full funding through Round 3 and FNSB received partial funding.I'm still working with FNSB to identify additional funding so there is a little uncertainty in the full scope of that project and which of the projects receives how much of the DOE funding.What I'm trying to say (unsuccessfully |believe)is that |will need to remain involved with the grant negotiations at least in the short term. If more information is needed I'd be happy to chat with folks.If we feel a short (<30 min)meeting is required |can set that up.

A Caltech researcher thinks arrays of tiny wind turbines could produce cheaper power than big ones. e by Kevin Bullis e April 8,2013 Though competitive in some cases,wind power needs to get cheaper still to displace large amounts of fossil fuels. 171 The remote Alaskan village of Igiugig-home to about 50 people-will be the first to demonstrate a new approach to wind power that could boost poweroutputand,its inventors say,just might make it more affordable. 4Testing the wind:Three,10-meter vertical-axis wind turbines at a demonstration facility in California. For decades,the trend across the wind industry has been to make wind turbines larger and larger-because it has improved efficiency and helped lower costs. John Dabiri,a professor of aeronautical and bioengineering at Caltech,has a heretical idea.He thinks the way to lower the cost of wind power is to use small vertical-axis wind turbines,while using computer models to optimize their arrangement in a wind farm so that each turbine boosts the power output of its neighbors. Dabiri has demonstrated the basic idea at a 24-turbine test plot in southern California.Grants totaling $6 million from the Gordon and Betty Moore Foundation and the U.S.Department of Defense will allow him to see if the approach can lower wind power costs in Igiugig.The first 10 turbines will be installed this year,and the goal is to eventually install 50 to 70 turbines,which would produce roughly as much power as the diesel generators the village uses now.Dabiri is also installing turbines at an existing wind farm in Palm Springs, California,using his models to generate power by putting up new turbines between existing ones. Ordinarily,as wind passes around and through a wind turbine,it produces turbulence that buffets downstream turbines,reducing their power output and increasing wear and tear.Dabiri says that vertical-axis turbines produce a wake that can be beneficial to other turbines,if they're positioned correctly. The blades of this type of wind turbine are arranged vertically-like poles on a carousel rather than spokes on a wheel,as with conventional wind turbines. Wind moving around the vertical-axis turbines speeds up,and the vertical arrangement of the blades on downstream wind turbines allows them to effectively catch that wind,speed up,and generate more power.(The spinning blades of a conventional wind turbine would only catch some of this faster wind as they pass through it-this actually hurts the turbine's performance because it increases stress on the blades.)The arrangement makes it possible to pack more turbines onto a piece of land. ittle wind:At a test plot in Los Angeles County,California, John Dabiri tests his concepts for wind farms made of small,vertical-axis wind turbines. Dabiri's wind turbines are 10 meters tall and generate three to five kilowatts, unlike the 100-meter-tall,multi-megawatt machines in conventional wind farms. He says the smaller ones are easier to manufacture and could cost less than conventional ones if produced on a large scale.He also says maintenance costs could be less because the generator sits on the ground,rather than at the top of a100-meter tower,and thus is easier to access.The performance of the wind farm at Igiugig will help determine whether his estimates of maintenance costs are correct. Dabiri says small,vertical wind turbines have other advantages.While the noise of conventional wind turbines has led some communities to campaign to tear them down,his turbines are "almost inaudible,”he says.They're also less likely to kill birds.And their short profile has attracted a $1 million grant from the Department of Defense to study their use on military bases.Because they're shorter,they interfere less with helicopter operations and with radar than conventional wind turbines. The approach,however,faces some challenges.Vertical-axis wind turbines aren't as efficient as conventional ones-half of the time the blades are actually moving against the wind,rather than generating the lift needed spin a generator. As the blades alternatively catch the wind and then move against it,they create wear and tear on the structure,says Fort Felker,director of the National Wind Technology Center at the National Renewable Energy Laboratory.Dabiri,and researchers such as Alexander Smits at Princeton University,say they are working on improved turbine designs to address some of these issues. Felker notes that Dabiri's approach will also require installing a thousand times more wind turbines,requiring potentially millions of wind turbines rather than thousands to generate significant fractions of U.S.power supply.And he notes that,over the last several decades,the wind industry has demonstrated that making ever larger wind turbines lowers costs ("Novel Designs are Taking Wind Power to the Next Level,”"Supersized Wind Turbines Head Out to Sea,” and "The Quest for the Monster Wind Turbine Blade.”"Going in the other direction,I believe,will not be successful,”he says."I don't think the math works out.” Felker thinks that Dabiri's approach might prove fitting for small,isolated places like Igiugig,where simpler construction and maintenance might be important."But if you're trying to transform the overall energy economy,”he says,"you've got to go big.”
