Eielson Air Force Base, Alaska --  Many consumers have felt the pinch of increased fuel cost in their wallets and Uncle Sam is no exception--high prices affect all who require fuel--but Detachment 460, a tenant unit at Eielson, is pursuing alternate means for energy. A move that will save money, reduce environmental impact and decrease maintenance time for Airmen. assigned to the unit are in the harsh climate Alaska can bring.

Detachment 460 reports to HQ Air Force Technical Applications Center, Patrick Air Force Base, Florida, and is the largest field detachment of AFTAC. The detachment has three mission areas that include maintaining 12 remote locations, throughout the state of Alaska, that deal with Atomic Energy Detection Systems and International Monitoring Systems. These sites are powered by propane, but now it seems solar power is a possibility, something that before didn't seem feasible considering there are times of the year where Alaska has less than four hours of sunlight a day.

"It seems we have advanced in technology to the point where solar systems in the dark arctic conditions of Alaska are viable; now we must overcome the old mindset that Alaska is just too dark in the winter for solar power," said Master Sgt. Andrew Morgan, Det. 460, superintendent.

The Geophysical Institute at University of Alaska Fairbanks uses other power systems at their remote sites and has shared that information. Sergeant Morgan said that having that information prompted the detachment to seek a better power solution.

While collaborating and sharing data with UAF on their already operational renewable energy sites Det. 460 goes out to each site and collects their own information using a solar pathfinder which provides a fast accurate solar site analysis. In a matter of minutes, the solar pathfinder shows the year-round, site-specific solar data to determine the best location and angle to setup solar panels.

"It is this great effort that will reduce our reliance on fossil fuels and will have less impact on the environment, but it is also a huge savings for the military, government and ultimately the American taxpayer -- that's something we can all get behind." said Maj. Anthony DeLuca, Det. 460 commander.

Currently Det. 460 plans on constructing a solar hybrid power system at seven different locations at a cost of $10,000 per site. Maintenance of this system consists of periodic battery replacement every 5-8 years at a low cost of two to three thousand dollars per entire battery bank. Once the system is installed and the initial cost is paid the estimated maintenance cost over a five year period will be $21,000 compared to the current propane system that runs at $160,000.

"The price for all fossil fuels is sky-rocketing, and propane is no exception. We've incurred a steady 10-15 percent every year on propane cost with no plateau price anticipated in the near future," said Major DeLuca.

Some of the challenges with having propane though aren't about money.

Since these sites are off the beaten path Det. 460 Airmen must make several trips hauling smaller propane tanks in a sled behind a snow machine or airlift taking an average of 300 man-hours to maintain proper fuel levels at all site locations. The 1000 gallon main propane tanks are stored underground and connected to thermo electric generators. Propane also has a problem of liquefying at temperatures of negative 50 and lower causing the pilot light to go out. The Airmen then have to make a trip out to the location to replace or fix any parts that broke during the flameout period; this cost accrues an average of $500 per visit and averaging two to four re-light trips a winter.

"Anytime a thermo electric generator fails, it requires immediate maintenance to restore these critical national sensors back to operational status; and a long snow machine ride in these arctic temperatures to these remote sites are very challenging and pose dangerous exposure conditions to our Airmen," said Staff Sgt. Stewart Raring, Det. 460 Site Supervisor.

As with anything different, things have to be worked out and looked at all angles, something which Det. 460 is actively doing.

"We're still working on a technical solution proposal for our headquarters, AFTAC. Once they have approved the engineering solution, we'll take the funded proposal to 354th Fighter Wing leadership and 354th Civil Engineering Squadron to lay out the tactical implementation of the final alternate solar power solution," said Sergeant Morgan.
