CHARLOTTE, N.C. -- The cold snap that left the Carolinas in a deep freeze is finally over. While the ice and snow are melting, your energy most likely has risen during the cold snap.

"Extremely low temperatures typically will cause a spike," said Meghan Miles with Duke Energy.

Temperatures that reached single digits led to Duke Energy customers using more than energy than ever.

This past Friday, a new record was set with people using a whopping 21,623 megawatt-hours which eclipsed the record during the Arctic blast of February 2015 when customers used 21,101 megawatt-hours.

"We saw energy usage rise about 20-25 percent," recalled Miles of the similar cold blast in 2015, which could equally spell a higher energy bill.

PSNC Energy tells NBC Charlotte that an average customer with $130 energy bill could see a spike of $50 to $60 dollars for the month of January.

They added that if we see unseasonably warm temperatures in the coming weeks then bills could even out.

Here are 5 things you can do to save money:

  1. Leave your blinds or drapes open on sunny, winter days but close them at night to help insulate your home
  2. Have your HVAC system checked annually by a heating & air conditioning contractor
  3. Change your air filters regularly
  4. Replace standard bulbs with CFL or LED bulbs.
  5. Reduce thermostat to lowest comfortable home setting
