Step by Step
to Restoring
Your Power

By John Johnston

Members of SMECO know that when they report their lights out, our line workers will come out in all kinds of weather to fix the problem. Whether the outage is one or two homes late at night, or thousands of customers after a hurricane or winter storm, what happens when our crews get the call?

SMECOs First Responders

SMECO’s servicemen are first responders, arriving on the scene to diagnose the cause of the outage.

The first line worker to take action is the serviceman. This employee is a first responder, an experienced line worker who troubleshoots problems on SMECO’s electric system. A service crew is the serviceman teamed with a line worker who is an Apprentice 7 or above, assigned as a helper. Together, they are first to arrive at the general location of the outage.

If a member reports their lights out during the working day, SMECO sends the service crew that is closest, so that we can restore power quickly. During evenings and weekends, the service crews rotate among weekly shifts where they are on call—nine crews in the Central Region and seven crews in the Southern Region.

A serviceman receives an outage alert from SMECO’s ARCOS text notification system regardless of the time of day. For off-hours outages, “you have to get ready like you’re going to work in the morning,” said Rob Dennee, a serviceman in the Southern Region. “You have to pre-trip the truck, making sure it has enough fuel and motor oil and the tires are filled and so forth. You log onto the truck’s computer and check the details of the job. Then I text my helper to let him know where we’re going. Sometimes he gets there first.”

For small outages at night, Dennee will attempt to call the SMECO member who reported the fault. He pulls into the driveway and makes the call, letting the member know that the cooperative is working on the problem.

“I treat the customers how I want to be treated. The person may not know I’m coming, so sometimes I will flash my truck lights to let them know I’m there, so I don’t frighten them,” Dennee said. “If I can fix the problem on site with the tools I have, I’ll take care of it and energize the line.”

Calling for Backup

Communication between crews and the Operations Center protects SMECO’s workforce from electric shock.

Repairing an outage often means replacing a damaged pole or insulator or transformer, a job that requires heavier equipment than a service crew typically carries. In such cases, the serviceman contacts the Operations Center and reports what they found at the scene. The center notifies the available chief linemen, who, like the servicemen, have a rotating call schedule for evenings and weekends. The chiefs assemble their crews at the regional office, discuss the specifics of the job, collect the parts they need, and head to the scene of the outage.

If the repair work will put our crews in traffic or close to an edge of a road, SMECO also asks a contractor to send a flagging crew to control traffic.

“A lot of times at night, I’ll ask to close down the road just because it’s secluded,” said Chief Lineman Andrew DeAtley, who has been with SMECO for 20 years. “In those conditions, any traffic can be dangerous to work in.”

Once at the job site, the assembled crews hold a tailgate conference to plan their work strategy and make sure everything is safe. Then they obtain clearance from the SMECO Operations Center to disconnect and ground any lines that must be repaired. It’s a two-way process that includes verification by both the Center’s system operators and the team in the field, ensuring that any other crews working up or down the line are protected from electric shock.

Many lines have reclosers, switches that allow SMECO to isolate a broken section and feed the other sections from a different substation or feeder line. “A substation is like a human heart and the feeder lines are like arteries, so the reclosers are like smaller arteries,” Dennee said. “We try to sectionalize the line to keep as many people on as possible, while still protecting our equipment at the substation.”

Faults on overhead electric lines are relatively easy to locate, at least in the daytime. Underground cables take much longer to repair, and not just because the lines aren’t visible from above.

To find a fault underground, the crew locates the problem using a thumper, a surge generator that sends high-voltage pulses through the cable. When a pulse reaches the fault, an electrical arc jumps to ground, creating a thumping noise and an electromagnetic field, which can be detected using a special receiver. “Normally within a half hour, we find the fault,” said Chief Lineman Marty Bowling. “How long it takes to fix the outage depends on how much hand digging we have to do and how much cable we have to replace.”

Before SMECO can do any digging, it must contact the Miss Utility service to have other utilities—gas, water, cable, and internet—locate their own facilities and mark them for safety.

“Depending on where you are, you may have to wait to dig, especially in St. Charles, where there are a lot of people and a lot of utilities,” DeAtley said. Once all the utilities have marked their lines, and the Operations Center grants clearance to disconnect the cable, the crew digs at the location of the fault.

When major storms cause widespread damage to SMECO’s electric system, our basic procedure for restoring specific outages remains the same. The changes are in our overall strategy. With an especially large emergency, we mobilize all our crews and the personnel who support them. SMECO’s outage restoration policy is to make repairs that will restore service to the most people in the least amount of time. We start with transmission lines and substations, move next to distribution lines that feed neighborhoods, and then fix tap lines and individual service lines.

“Sometimes we have to just cut our way in, and that can take a while since storms can bring down numerous trees,” Dennee said. “There was an incident this summer where it took hours and hours to get one road back on.”

Once the crews have finished making the necessary fixes, they get clearance from the Operations Center to close the switches and restore power to the SMECO members who are waiting. Before leaving, they repair any damage that their equipment made to the landscape.

Dennee urges SMECO members to always contact us when their lights go out. “We will come out and make sure it’s safe. Please bear with us, some nights I’ve come home and I didn’t have power myself,” he said. “I know it’s frustrating, but most people realize we can’t just snap our fingers and safely turn the lights on. It takes everyone at SMECO to make it happen, and their jobs make things better for those of us in the field.”
