Utility bills may notoriously spike during the sweltering summer months, but a woman in Texas said she didn't cool her home enough to warrant the electricity bill she received for $1,381,783.92.

Kristin Harriger, of Abilene, said she was expecting a bill from Potentia Energy for about $100, and thought it was a joke when she opened her statement and saw all those extra digits, according to the Abilene-Reporter News.

"I opened it. I read it. Then just went, 'Oh, my gosh. That's a lot of money," Harriger told the newspaper.

Harriger said she is a single mother and always pays her bills, but that she's confident that this new bill may float a little longer than usual.

Rather than the normal 9 cents per kilowatt-hour rate on her utility bill, the company charged her $1,000 per kilowatt-hour.

Harriger said she called the utility company and that employees there told her that it was either computer error or human error, and that they would get to the bottom of it right away.

According to the Abilene-Reporter, a Potentia Energy senior manager said an investigation into the lofty bill was conducted and it was determined that the bill was flagged to be held by internal auditors. However, the statement was mistakenly sent by a third-party billing vendor.

The company said a new bill reflecting accurate charges has been sent out to Harriger.
