February was quite a rollercoaster with a high of 88 degrees on Feb. 8 and a low temperature of 12 degrees just 12 days later.
That means North Texans likely had to use their air conditioners, then switch to the heater, in the same month, and in some cases on the same day!
Even though February had the lowest overall temperature of the winter, January packed a punch, with two winter storms bringing freezing temperatures that lasted far longer. However, CoServ Members should expect energy usage to be lower in February than in January.
| January | February | Difference | |
| Average temperature | 42.9 | 49.3 | 6.4 degrees warmer |
| Heating Degree Days | 678 | 448 | 230 less HDD | Cooling Degree Days | 0 | 16 | 16 more CDD |
| Utilities and the federal government measure the impact of weather on energy usage by calculating Cooling Degree Days (CDD) and Heating Degree Days (HDD). To calculate the CDD, take the average temperature for a day and subtract it from 65. The higher the number, the more air conditioning will be needed to keep your home comfortable.

You may remember that February 2024 was particularly mild with an average temperature of 57.7 degrees. February 2025 had an average temperature of 49.3 degrees, or 8.4 degrees colder. In addition, the winter storm that rolled through in mid-February resulted in 229 HDD over seven days, accounting for nearly half the HDD for the month. There were nine nights altogether with temperatures below freezing.
The cooler temperatures and winter storm resulted in more heater usage, which increased by 45% compared to last February. Members should expect energy usage to be higher than last February.
CoServ Gas Customers who have gas heaters could also notice a decrease in electricity usage while gas usage will increase. January and February typically have the highest gas usage of the year. It steadily decreases each month through the spring and becomes even lower in the summer.
There were seven days with temperatures 75 degrees or higher, which resulted in minimal CDD.
The region only had 1.35 inches of rain, down nearly an inch and a half from normal.
The closer the temperature is to 65 degrees, the less heating or cooling needed to stay comfortable indoors. Spring is on the horizon and with it typically comes more mild temperatures that hit that sweet spot.
Rates
While the weather is often unpredictable in North Texas, CoServ Members can count on their electricity rate to remain affordable.
When we save money on our wholesale electricity purchases, we pass those savings on to our Members by adjusting the Power Cost Recovery Factor (PCRF) on your bill.
For the ninth month in a row, CoServ maintained the PCRF as a negative number, meaning it subtracts from the base rate. And for the fourth month in a row, the PCRF has remained the same at -$0.01 per kilowatt-hour.
By making strategic power purchases weeks, months and years ahead of time, CoServ locks in lower prices to shield us from high spot prices. This is one of the biggest benefits of being a CoServ Member, or what we call, the CoServ Advantage!
