The politics surrounding the development and distribution of cost effective energy resources for Alaskans.
I am assuming that you have messed around with the Homer simulation models? Are you expanding upon that type of platform that includes several modular components to the RES? It seems to be fairly accurate and is incredibly usefull in early stages. B…
Alan and others,
You might want to check out the Shark power meters, they pretty inexspensive rugged little buggers. The communication protocol is real simple to integrate and can help from a cost standpoint if you are doing a ton of load monitorin…
Folks in AK should be aware of carbon financing as a non-traditional way to enale project finance. The market is very imature at this juncture due to the backing being all private finance. Huge oppurtunity for AK projects as they effectively offset…
Well in a simple sense their needs to be direct lines of communication and direct lines of responsibility. SCADA is the key to everything at that critial cross-over with plant operator and wind turbine operator, they infact should be the same person…
Have you looked into the SEL syncrophasor application? It could be benefitial to track power quality real time, or depending on the power meter you are using could be integrated with an RTU control. What type of SCADA system is the system using? I a…
The Regional IRP addresses the need for the state power market to be more condusive to IPP development. This makes big wind happen with the way the bond market is for utilities. It will involve a huge educational effort to utlities boards and ultima…
(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)

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 kno…

- The picture below was pre-comissioning so the turbine was not moving, hence the large accumulations

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 Baner) 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 inclredibl 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

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, p
rimarily 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.
