Area ProjectsCommunitiesserved by AVEC• AVEC is striving tobe as efficient as possible• Installing fuel-efficientengines• Installing automatedcontrol systems thatdispatch themost efficient enginefor the load.Kiana – new fuel-efficientDetroit Diesel Series 60#7

Selawik• Power plant andtank farm – beforeupgrade#8

Selawik• Selawik, newautomated powerplant, elevatedbulk fuel tankfarm and fourwind turbines#9

Improving EfficiencyCommunitiesserved by AVEC• Using low loss transformers• Using recovered heat where possible– Being done in Selawik– Renovations needed – Kiana, Ambler– Possible new project – Kivalina#10

Fuel Storage andTransport• Fuel fill lines have beenbuilt to the airports at:– Noatak– Ambler– Shungnak• To aid fuel delivery whenbarges cannot deliverReceiving fuel at Ambler#11

Fuel Storage andTransport• Look at options forroad access to Noatak– Could store fuel atRed Dog port andtransport by truck• Options for fuel storage on the Kobuknear Noorvik or Kiana to better serveAmbler and Shungnak/KobukNoatak – aerial view#12

Possible Interties• Ambler – Shungnak/Kobuk– Might enhance Kogoluktuk hydro feasibility• Noorvik – Selawik• Kivalina – Red Dog Port– Possible wind generation near Red Dog Port– Not enough room at Kivalina for windgenerators and airport access#13

Renewable Energy Possibilities• Wind within aneconomical transmissiondistance to many Kobukarea AVEC villages islimited• Kivalina is windy butthere is not enoughroom for utility gradeturbines and safe airportaccessKivalina#14

Renewable Energy Possibilities• Possible windpotential using theold runway atNoorvik• Possible windpotential on ridgesnear KianaMet tower locationand potential windturbine site on oldrunway in Noorvik.#15

Renewable Energy Possibilities- Solar Power• Due to high fuelcost, AVEC will lookat 50 kW solar PVfor Noatak, Ambler,Shungnak andSelawik• Goal – can we put inenough PV todisplace stationservice and linelosses and therebyincrease dieselefficiency?New power plant siteand possible solararray in Shungnak.#16

Kiana• Bulk fuel tankfarm – beforeand after#17

Kiana• Distribution upgrade to overhead#18

Ambler• Power plant and tank farmand new fill line to airport#19

Bottom LineStrive to beforward lookingand as efficient aspossible untilviable long termsolutions emerge
