FONTANA, Calif. (KTLA) -- The power was back on Wednesday morning for thousands of residents in Huntington Beach and Fontana.

The lights went out for more than 15,000 people in Fontana around 8:40 p.m. Tuesday, after a Mylar Valentine's Day balloon floated into a substation.

A utility spokesman said balloons cause problems every year on Valentine's Day.
