Diesel-Powered Backup Generators are Essential for Port Operations. Not everyone has one.

“Argonne found that 31 percent of America’s ports do not maintain any physical backup measures for the loss of electric power, meaning they rely solely on external power sources. This presents an incredible, urgent opportunity. Port authorities across the country should prioritize upgrades and installations of reliable emergency backup power systems.” percent maintain a backup generator, 31 percent maintain a UPS, two-tier emergency backup power to the port’s operations. and 22 percent maintain both.
