Alaska Village Daily Load Profile 12 Replies
Other than the Alaska Village Load Calculator are there any publications which include daily electrical load profiles for AK Villages? It seems that this could be solved by the PCE program collecting…

Secretary Chu Announces Closing of $117 Million Loan Guarantee for Kahuku Wind Power Project
Energy Secretary Steven Chu today announced that the U.S. Department of Energy (DOE) has finalized a $117 million loan guarantee for Kahuku Wind Power, LLC, the owner and operator of the Kahuku Wind Power project.
DOE Announces $30 Million for Small Business Clean Energy Technologies
DOE has announced $30 million in Recovery Act and FY 2010 funds to help small businesses commercialize promising new technologies. Applications are being accepted in the technology areas of biomass, buildings, geothermal, photovoltaics, wind power, vehicle efficiency, and energy transmission and storage.DOE and DOI to Spur Offshore Renewable Energy Projects
DOE and the U.S. Department of the Interior (DOI) have signed a new Memorandum of Understanding to bolster their partnership on the future development of commercial renewable offshore wind and water energy projects.DOI and 10 East Coast States Form an Offshore Wind Energy Consortium
The U.S. Department of the Interior (DOI) and 10 East Coast states have established the Atlantic Offshore Wind Energy Consortium to promote the development of wind resources on the Outer Continental Shelf.AWEA: U.S. Market for Small Wind Turbines Gained Ground in 2009
The U.S. market for wind turbines grew by 15% in 2009, according to a new report from the American Wind Energy Association (AWEA). That's a far slower growth than the U.S. market experienced in 2008, but given the economic situation, it's not bad, and AWEA is thanking the Recovery Act.Comment Wall

(Pre-Commissioned turbine - hence the large accumulation of ice; we dont see this kind of build-up while in operation, but shows how big big of a punch it can throw. Dec 08)
Some of the fun stuff we are now able to tackle in terms of keeping the tip brakes working optimally. The solutions we are currently working on and joint problem solving with Kotz:
- Eliminating the spring mechanism for a retractable cable. (Currently under testing at both Kotz and Banner) Initial promise but more data is needed.
- Using inorganic and organic coatings on aluminum surfaces. Theoretically recuding ice adhesion up to 90% (we will see). Coatings motly deveoped by NASA for shurttle re-entry. Blade tepholon basd coatings are showing inclredible results in Nome.
- Replacing constant force spring with linear force spring; thus adding more holding strength while in operation and not comprimizing braking process/streses.
- Using dual purpose electro magnets; both creating magnetic field and thermal heat. Hope is to boost connectivity issues between electromagnet and holding plate in certain enviormental conditions like ice and frost by breaking ice adhesion bonds in certain conditions

Wind Turbine Maintenance: Bottom Line for Regional Success
Hope to post some nuts and bolts comments soon involving Ice, Corrosion, and Communications but figured I'd start my comments with a fluffy mission statement.
As having the first (as I know) full time wind technician in Nome Maintenance has always been a part of our future/present development. To assist our full time person we need a network of part-time technicians to execute specific tasks when needed. Up unit this point we have spend an above average amount of time with the system at Banner Ridge and will continue to do so until we begin to modify existing issues.
With the reduction of maintenance time and energy spent with Banner coupled with the expanding mature local workforce we are now looking at providing expanded services within the region. Our scope can involve one time immediate work, or up to full Asset Management.
We believe it will begin to capture efficiencies in O&M costs, primarily leveraging the proximity of a knowledgeable workforce and economies of scale. Ultimately leading to lower cost, higher reliability wind energy with strict responsibilities to ensure we do everything within reason to keep the blades turning.
