Jonesboro, Ark. — The Jonesboro power grid has successfully managed record-setting demand during this summer’s intense heat, according to City Water and Light (CWL). However, residents may notice an increase in their energy bills as a result of the higher usage.
City Water and Light Energy Marketing and Purchasing Director Slade Mitchell explained that Jonesboro’s grid is part of a much larger network managed by the Midcontinent Independent System Operator (MISO). MISO is a nonprofit regional transmission organization that oversees electricity delivery across a swath of North America, from Canada to the southern U.S., including parts of Louisiana and Texas.
“So the larger system that we’re connected to is called the Mid-Continent System Operator, or MISO,” Mitchell said. “It stretches kind of the middle part of the United States, as far south as Louisiana and then parts of Texas, all the way into Canada.”
While grid stress can sometimes lead to blackouts, Mitchell assured customers that no outages have occurred locally and protocols are in place to prevent electrical disruptions. “The larger system at times has had stress, and when you have those kinds of stress, they make adjustments, send out certain indicators to us, and then we’re directed in certain manners to try to react," Mitchell explained.
Mitchell praised CWL’s investments in local infrastructure, which he said have improved reliability and performance. “We’ve been very pleased with the way our system has performed during the heat,” he said, adding that upgrades made in anticipation of summer demand have ensured stability.
Beyond local efforts, Mitchell acknowledged MISO’s role in maintaining regional balance during this challenging period. “The demands have stretched the system. But MISO, the larger system that we’re connected to, they’ve done a really nice job managing that and continue to do so as of right now,” he said.
The U.S. Energy Information Administration notes that rising demand often requires utilities to invest in new infrastructure, such as power lines and generating plants, leading to higher costs for customers. Jonesboro resident Cindy Gosha shared her experience, saying, “I keep my house at 72. I’ve seen a slight increase in our electric bill, but not too awfully bad.”
CWL officials said they are not predicting any major grid disruptions or issues for the near future. However, they continue to closely monitor conditions as summer heat persists.
