DTE Energy has completed emergency repair to the substation in Dexter, Minnesota, where one of the two substation transformers had failed and had to be replaced.

According to DTE spokeswoman Randi Berris, after an alarm and visual inspection of the failing transformer it was determined for safety reasons and power needs that the unit had to be repaired, reports The Sun Times News.

"It's a very complicated job to replace a 100,000-pound transformer, and the outage was necessary so the crews could work safely inside the substation to remove the old transformer and install the new one," Berris said.

"We took the opportunity also to upgrade the transformer to one with the newest technology. It will be able to carry increased load and support future growth and economic development in Dexter," Berris added.
