Mobile substations play a crucial role in keeping the lights on, often in fast-growing areas with increasing energy needs.
Here are some ways UniSource has grown and worked to improve service for customers over the last two decades.
Our preparations are focused on supporting rapid service restoration, in part by ensuring the availability of critical equipment and supplies.
Failure of just one critical piece of equipment in a substation can cause an outage that requires costly repairs and impacts our customers.
If you are planning to dig, it is important to call 811 to have any underground utility lines located and marked before you start.
Because our electric grid covers 8,056 square miles, maintaining it is an enormous undertaking.
A volatile year highlights the commitment of UniSource employees to protect their community’s safety and economic health.
