The 340-foot tall shipping crane would be a massive power hog. Demand would spike every time it lifted a container off a cargo ship. When Rick Kniaziowski, the terminal manager for the shipping company Matson, first asked about getting it, the head of the local utility said no.
"His eyes got really big," Kniaziowski says. He was told, "Everyone's TVs are going to brown out, and they're either going to hate you or they're going to hate us.'"
But the utility looked around for a solution, and it found a European company, ABB, that offered a new kind of energy storage: flywheels.
