Gainesville Regional Utilities (GRU) announced on Monday that its fuel adjustment for electric customers will increase in January because of a rise in natural gas prices caused by cold temperatures across the country.  

GRU said its fuel adjustment would rise from 35 mills to 40 mills per month. The increase would cost a 1,000-kilowatt-hour per month customer an additional $5.  

In the press release, GRU noted that it makes no profit from the fuel adjustment millage and only raises or lowers the adjustment to cover the cost of natural gas. These fuel adjustments are standard at utilities, but the rates vary.  

Coming off high natural gas prices in prior years, GRU leaders in 2023 reduced the fuel adjustment millage four times, from 80 mills to 40 mills, and lowered it in 2024 to 35 mills.

In January 2023, the fuel adjustment, or fuel pass-through cost, nearly equaled the cost of the base rate plus the monthly customer charge. At the time, Gainesville had the second-highest electric bill in Florida, but largely because of $45 in monthly savings through the lower fuel adjustment, Gainesville ranked 13th most recently, according to the Florida Municipal Electric Association.  

For November 2025, with its 35-mill fuel adjustment, Gainesville had the 10^th-highest fuel adjustment. 

Fuel adjustment as a portion of the monthly electric bill for 1,000 kilowatt hours 

January 2023 

• Fuel adjustment at 80 mills: $80 

• Base rate: $86.13 

• Customer charge: $16.50 

• Total: $182.63 

November 2025  

• Fuel adjustment at 35 mills: $35 

• Base rate: $84.60 

• Customer charge: $17 

• Total: $136.60 

In its press release, GRU said it is taking steps to mitigate fuel adjustment increases by entering long-term, pre-paid fuel arrangements and having power plants that run on a variety of fuel sources.  

GRU recommended the following tips to reduce winter bills: 

• Set your thermostat to 68° F.    

• Raise your thermostat at one or two degrees at a time to avoid activating expensive emergency heat strips.   

• Lower your thermostat when leaving home for eight hours or more.   

• Weather strip doors and caulk windows.   

• Check your air filter monthly and change when needed.   

• Open curtains during the day to let sunlight in and then close them at night.   

• Keep your fireplace damper closed when not in use.   

• Set the temperature on your hot water heater to 120°.   

GRU customers can request a utility staffer to come and inspect the windows, doors, ductwork, insulation and other energy infrastructure on their dwelling for tips and advice.
