DTE Energy will give approximately 8,000 customers credits on their bills following a July 17 in Berkley and Royal Oak during record-setting heat.
The credits will be for $25 to $250, depending on the length of the customer's outage, said DTE spokesman Alejandro Bodipo-Memba, who added all eligible customers have been contacted via a recorded phone message.
Anyone with questions can call 313-235-4141, he said.
The July 17 equipment failure in Royal Oak that caused the fire was so intense it blew out a window and a door several feet away in the substation, Royal Oak Fire Marshall Fire Marshal Tom Nikkila said.
"It was a high-heat fire," he said. "It was quite an event.
"I am not an electrical engineer. You would have to talk to DTE," Nikkila said when asked about the fire's cause. "I can tell you it was 102 degrees that day. The demand for electricity had to be incredible."
The National Weather Service issued an excessive heat watch that day for southeast Michigan and the Detroit Free Press reported that the high hit 101 degrees, which tied a record first set on July 17, 1887.
Some customers in Berkley and Royal Oak who were impacted by the ensuing outage were without power for up to two days, Bodipo-Memba said.
"We obviously recognize this was a difficult time for our customers to be without power and we wanted to be proactive in providing credits for their inconvenience," he said.
and, while Bodipo-Memba said the service interruptions should be over, the work continues.
The damage was "pretty significant," he said.
