Heavy rains brought mild temperatures, which held the summer heat at bay in North Texas. It was the mildest May since 2021, and as a result, CoServ Members can expect energy usage to be less than in May 2024.
The weather overall was reminiscent of April. So, Members should also expect energy usage to be similar to April.
The chart below explains how utilities measure Cooling Degree Days and Heating Degree Days, which link average daily temperatures directly to energy usage.
| April | May | Difference | |
|---|---|---|---|
| Average temperature | 67.9 | 74.1 | 6.2 degrees warmer |
| Heating Degree Days | 63 | 2 | 61 less HDD |
| Cooling Degree Days | 157 | 295 | 138 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.

Temperatures ranged from a low of 53 degrees on May 2 and 3 to a high of 95 degrees on May 25, the day before the Memorial Day deluge. In fact, nearly half the rainfall for the month came on Memorial Day when more than 2 inches fell.
The average temperature for May was 74.1, 6.2 degrees higher than the average temperature for April. While air conditioning usage might have increased in May, there was no need to run the heater, which saves on electricity if you have an electric heater or natural gas if you have a gas heater.
Overall, temperatures reached 90 degrees or higher on six days last month, and lows were 70 degrees or less on eight days.
RATES
Once again, CoServ has kept electric rates low for our Members.
For the 12th month in a row, CoServ maintained the Power Cost Recovery Factor (PCRF) as a negative number, meaning it subtracted from the base electricity rate. The PCRF will be -$.005 per kilowatt for June billing.
The Standard Residential rate for June will be 12.73 cents per kWh.
We make every effort to keep electricity rates affordable while delivering safe and reliable power to Members. When we save money by making strategic wholesale electricity purchases, we pass that on to Members, as we did this month.
