DTE Energy is the twelfth-largest utility in the U.S., serving 2.2 million customers in the state of Michigan. When disruptions to its electric grid would cause power outages, DTE used to spend hours figuring out where it needed to send repair crews. Now, AVEVA PI System can locate disruptions in five minutes and send out emails and texts to crews on the ground with maps of where the damage is.
“I’ve been hearing a lot about this Internet of Things. This is a good example of that–putting out these low-cost sensors, incorporating them into the PI System.”
