UniSource Energy Services maintains and strengthens our energy grid year-round to prepare for the challenges of summer, including high temperatures and powerful thunderstorms.
System inspections and upgrades continue throughout the year. In 2024 alone, UniSource invested more than $24 million in power lines, transformers, electric switches and other transmission and distribution equipment that serves our communities every day.
“We work very hard throughout the year to maintain and improve our grid because we know this is when our customers count on us the most,” said June Deering, Director of UniSource electric services. “High temperatures, high energy use and thunderstorms all present challenges. We want our systems to be as resilient as possible in time for summer, when customers usually use the most energy.”
Recently completed and ongoing upgrades help UniSource serve customers’ increasing energy needs and strengthen the system to reduce the likelihood of potential storm damage. These improvements include:
- Lake Havasu City: $2.2 million to upgrade transformers at the London Bridge Substation, and investing about $1 million in a new feeder line from the Mulberry Substation.
- Kingman: About $1.8 million to complete the new Meadview Substation. UniSource has invested more than $10 million in the project over five years. Crews also installed new breakers at the Yucca Substation, an investment of about $1.5 million in 2024 alone.
- Santa Cruz County: About $725,000 to upgrade breakers at the Kantor Substation.
Our investments in our local energy grid have helped UniSource maintain top-quartile reliability scores when compared to other energy providers across the nation.
In 2024, the average UniSource customer was without service for about 60 minutes. That compares to a nationwide average above 100 minutes, with a number that falls well within the first quartile of results gathered by the Edison Electric Institute.
