The aging United States electricity grid is facing an increasing number of threats, ranging from severe weather events to solar flares to cyber terrorism.

Inside Energy research has found major power outages have doubled every five years since 2000. It's something the U.S. military is taking seriously, helping lead the way in the development of smaller and more secure grids - known as microgrids.

Ramon Crockett is a supply specialist at the Fort Carson near Colorado Springs. He describes his team as the Home Depot of the 31,000 person post. He spends much of his day trucking whatever people need around the base. But, it's a quiet job, owing to the whispering electric engine in his delivery truck.

"Yeah, it's nice, all the guys say I sneak up on 'em," Crockett laughed. His truck is one of a small fleet of electric vehicles driving around Fort Carson, carrying refrigerated goods, weapons and even troops heading out to train. The trucks make up an important piece of the base's microgrid project known as SPIDERS, an acronym for Smart Power Infrastructure Demonstration for Energy Reliability and Security.

"It's all about ... what can we do in the event of a catastrophic outage," said Bill Waugaman, who leads energy security for U.S. Northern Command - the military's homeland defense arm. Waugaman has overseen SPIDERS projects at Fort Carson and at bases in Hawaii. Those bases are still hooked up to the same electricity grid we all use. But, if there's a blackout on the main system, SPIDERS allows electricity to keep flowing to the bases' most important buildings from power sources on site.

At Fort Carson, a field of solar panels and diesel generators provide power which can be used immediately or stored in the batteries of the base's electric vehicles.

Microgrids are not new. GTM Research counts 124 in the U.S. as of now, often at hospitals, universities and research facilities, as well as military bases. But, they usually rely solely on diesel generators. During Superstorm Sandy, diesel shortages wracked the East Coast. Waugaman said generators failed in multiple hospitals from overuse at that time.

The combination of renewable energy sources and batteries found at Fort Carson could provide a prescription for a more reliable microgrid.

And Waugaman said military bases provide an important testing ground for such a suite of technologies. He said these real world tests are something hospitals or Wall Street wouldn't be willing to do, so pilot projects like SPIDERS could eventually drive markets in the private sector.

Colorado real estate investor Craig Harrison is developing what he calls the "world's largest planned microgrid" in Weld County. This square mile Niobrara Energy Park sits at the intersection of major electric transmission, natural gas pipelines, and one of the largest fiber optic hubs in the country.

Harrison wants to pool those resources and combine them with renewables on site to lure in major technology companies like Apple or Google to build data centers there. He thinks the project could be worth $10 billion dollars one day. GTM Research predicts the market for microgrids will grow nearly 270 percent by 2020.
