Pacific Gas and Electric warned Bay Area residents Thursday of a new scam the company said targets people through emails that pose as PG&E bills.
PG&E representatives said no security breach has occurred and information contained in the fraudulent email is illegitimate.
"It's unacceptable that someone is trying to take advantage of our customers and others," said Helen Burt, senior vice president and chief customer officer for PG&E. "We take our customers' security very seriously and under no circumstances would we email anyone to request that they provide personal information without first logging into 'My Energy' or calling us."
Company officials said they are investigating the situation with law enforcement.
The emails, which have been sent to people inside and outside of PG&E's service area, request information about recipients and their utility accounts, according to the company.
PG&E advised recipients not to respond to the request, click on any links, open any attachments or provide personal information. The email should be deleted immediately and reported to company security at CorporateSecurity@pge.com.
This latest scam is similar to other recent email and phone schemes targeting customers of several utilities across the country, according to PG&E.
