Cold days and nights in December and January brought true winter temperatures to the Tri-County service area. After a warm November, many members noticed a jump in their electric bill. 

“Cold temperatures really drive up energy usage, particularly for heat pumps when the low temps drop below 30 degrees,” said Greg Mullis, VP of Corporate Services.  “On these colder days, electric heat pumps automatically use back-up auxiliary heat - also known as emergency or strip heat - to bring up the temperature. While effective, this auxiliary heat uses much more energy.” 

Homes that use resistance electric furnaces and space heaters can see an even more dramatic increase in usage on cold days. “Space heaters are not an efficient way to heat the entire home. They are great for taking the chill out of a small room if used just a few minutes at a time, but they are not energy efficient, and are much more costly than heat pumps.”
