Academy hits switch on 6-MW solar array
Lt. Gen. Michael C. Gould speaks at the dedication ceremony for the Air Force Academy's 6-megawatt solar array June 13, 2011. The array will produce about 12,000 megawatt-hours per year, or 11 percent of the Academy's overall energy needs. The Academy's vision is to produce 100 percent of its power through renewable resources by 2020. General Gould is the Academy superintendent. (U.S. Air Force photo/Mike Kaplan)

Academy hits switch on solar array

6/13/2011 - U.S. AIR FORCE ACADEMY, Colo. (AFNS) -- Officials with the Air Force Academy, Colorado Springs Utilities and SunPower Corp. flipped a switch signifying the official dedication of the Academy's 6-megawatt solar array in a ceremony June 13.

Academy Superintendent Lt. Gen. Michael C. Gould called the event significant because it demonstrates the partnership between the Academy and the local community to bring renewable energy to the Colorado Springs area.

"At the strategic level, a lot of us talk about getting serious about the renewable energy business," General Gould said. "We did it. This shows action and leadership at many levels. And it shows our 4,400 cadets -- the reason why we're all here -- what bold leadership is about and what making a commitment and taking action is all about."

The partnership to develop the array began at the federal level, with $18.3 million of American Recovery and Reinvestment Act funds set aside to build the facility. Colorado Springs Utilities won the contract, and SunPower oversaw the construction.

"The Air Force Academy is a treasure for Colorado Springs," said Colorado Springs Utilities CEO Jeff Forte, a Colorado Springs native. "So to work on this project as partners is just tremendous for us."

The solar array fits into the Academy's objective to generate 100 percent of its electricity needs on base by 2020 as part of the Defense Department's Net Zero Energy Installation initiative.

It also helps the city of Colorado Springs move toward its goal of producing 20 percent of its energy through renewable sources by 2020, Mr. Forte said.

General Gould credited several officials with the 10th Air Base Wing and the contractors for their partnership in the solar-array project. He also credited Russ Hume, the Academy's energy czar, for his involvement.

"Russ, your leadership, your push and your drive has made all this happen," General Gould said.

Because the government paid the construction and maintenance costs up front, the Academy will receive the electricity at no cost throughout the facility's lifetime, Mr. Hume said. Moreover, the array will generate the most electricity during peak times of the day, when electricity is most expensive. This will save the Academy as much as $1 million per year over the course of the array's 25-year design lifetime.

Mr. Hume said the array constitutes about 11 percent of the Academy's overall electricity needs: about 12,000 megawatt-hours per year, or enough to power more than 1,200 average homes.

The facility has also presented opportunities for cadets and will continue to do so, Mr. Hume said.

"Cadets have been involved with this project from the beginning," he said. "They were involved with determining the most logical sites for placement of the array."

Cadets are also involved with researching improvements in photovoltaic technology and cyclical wave energy, Mr. Hume said.

General Gould said the solar array brings the Academy closer to its Net Zero goal, but much work still remains.

"We have to meet this Net Zero goal by 2020, and we're going to continue with the partnerships to make it all happen," he said.

Granted reducing emissions and dependency on fossil fuel is important but I share the same concerns as SNCO. So operating at peak capacity, the $18.3M project will save as much as $1M per year savings. Doesn't take much in annual maintenance or reduction of production capacity to see that this project yields NO actual savings. Not the return in investment the AF probably needs to be looking at.

Assuming no maintenance or operating cost and a consistent KW output, this system will have a 0.061 per kw cost over the 25 years, the projected saving listed in the article.

I wonder if that includes the cost of the land to house the system and the annual taxes on that land. It does say the maintenance was paid for upfront so that's good. I am all for using renewable resources but I think solar is a waste of money. The life of these systems is about 25 years so after that it will need replaced, so the savings are nil. Not to mention that right now solar and wind are just not feasable energy options and for them to waste money on getting to 100 percent is just impractical. Plus, I doubt we will run out of oil and gas in 25 years.

And the air will be cleaner... Makes perfect sense. It's not always about money it's also about decreasing our reliance on the fossil fuels that pollute our world. Great Job USAFA, lets expand that solar array.

We're going to run out of oil and coal long before we run out of sunlight. From that perspective, this solar array makes sense.

Someone do the math for us...what is the real cost per kilowatt?

OK so let me see if my public math is correct. We spent 18.3M to construct a Solar Array for the USAFA. This Array will save approximately 1M annually for the next 25 years. That equals a savings over the life of the system of approximately 6.7M which equates to 268K annually. How much of that annual savings is used on maintenance upkeep manpower etc. to keep this system going These Net zero programs are netting zero savings. Good business plan.
