Readers messaged just before 9pm Sunday night:
“My lights just flickered and something very loud (transformer?) sounded like it just exploded in Columbia Heights”
“What on earth was that explosion just now in Petworth?”
Thanks to J. for sending the explanation (and photo above) last night:
“An oil switch and a transformer blew on Newton and 16th. The Pepco team was here doing work on the transformer and clearly something went wrong.”
Looks like power has been restored.
