The military is among the largest buyers of independent power systems known as microgrids. They make tactical sense; and environmentalists hope they can help the transition from fossil fuels.
SAN DIEGO — Col. Thomas Bedell had been commanding Marine Corps Air Station, Miramar in San Diego for just one day, in July 2021, when he got a message from the base energy management director. The city power system was straining under a heatwave, and it was time to start up the microgrid.
Using energy sources including solar and methane gas from the rotting garbage in a massive San Diego city landfill located inside the base, Miramar can go 21 days in a self-contained state that's called"island mode." Or as Col. Bedell says, aircraft carrier mode. "It's designed to operate the first Air Force or Air Force's North Headquarters building completely independently for up to four and a half hours," he said.
for generators to power bases in war zones, a vulnerability that proved deadly in Afghanistan and Iraq. Newell retired as colonel, and started a company promoting the mobile combat energy solutions he says will be even more important in the next war. He spent his last years in the Marine Corps helping stand-up the microgrid at Miramar Air Base.
