The Mobiles are FAST
Including mobile substations in Strategic Transformer Reserve Program
Both spare large power transformers, and emergency mobile substations, have critical roles in the U.S. Department of Energy's Strategic Transformer Reserve Program, STRP. An emergency mobile substation can literally roll onto the site on the bed of a truck, run connecting wires to the power lines, and bypass all of the damaged substation equipment, allowing electricity to flow again within hours.
