But what does a tremendous save look like in natural gas safety?
In Witt, Illinois, it started with a quiet alert from advanced metering technology and ended with a coordinated response that prevented what could have been a devastating explosion.
A Warning Before Anyone Knew
The incident began not with a customer call, but with data.
Ameren Illinois’ advanced metering infrastructure (AMI) flagged unusual activity at a residential gas meter, detecting a spike in usage that didn’t match normal patterns.
“Dispatch monitors AMI and receives alerts daily,” said Tyler Millburg, a gas supervisor based in Hillsboro. “When they see a significant spike outside normal usage, that triggers an investigation.”
Such spikes can indicate anything from appliance issues to more serious concerns like leaks. In this case, the alert prompted dispatch to send a gas journeyman.
“Our average response is about 22 minutes,” Millburg said. “Once on scene, we begin verifying conditions right away.”
Initial readings confirmed elevated gas levels both inside and outside the unoccupied home.
A Scene Escalates Quickly
At 9:05 a.m., the Witt Volunteer Fire Department was dispatched.
“We were on scene in about six minutes,” said Fire Chief Don Keiser.
Ameren personnel were already there, providing a critical advantage.
“He was getting some pretty high, concerning readings on the outside of the home,” Keiser said.
Although the house was locked, readings suggested gas was accumulating inside. Fire crews secured the area, blocked nearby streets and assessed surrounding homes.
“When Ameren Illinois is already on scene with that kind of reading, you know there’s an issue,” Keiser said.
Coordinated Response
With conditions worsening and the homeowner still en route, Ameren Illinois and fire personnel made a joint decision to act.
Meter activity had already indicated a serious issue.
“If that dial is moving rapidly, that’s a sign of significant gas flow,” Millburg said. “Our journeyman turned off the gas at the meter, and a lineman shut off electricity to the house.”
Without access to the home, Ameren requested emergency assistance.
“Our dispatch contacts fire and police, and we coordinate closely once they arrive,” Millburg said.
Firefighters forced entry and, wearing breathing apparatus, escorted an Ameren journeyman inside.
Identifying the Source
After ventilating the structure to safer levels, crews traced the source of the leak to the basement.
“A fuel line to the water heater had broken at a copper flare fitting,” Millburg said.
He noted that this type of failure is a known risk, particularly in older installations.
“The compound that gives natural gas its odor can react with copper over time,” he said. “The line may appear fine on the outside but deteriorate from the inside out.”
The flared section of the pipe is also the weakest point.
Crews ventilated the home further, reducing gas concentrations and stabilizing the situation.
What Could Have Happened
The entire response took less than an hour, but the potential consequences were significant.
“It could have been deadly,” Keiser said. “That house was full of gas. All it needed was an ignition source.”
The danger extended beyond a single home.
“Houses nearby were very close,” he said. “It could have impacted more than just that property.”
After more than 30 years in the fire service, Keiser didn’t hesitate.
“That’s probably the closest call I’ve ever been around,” he said.
Technology That Made the Difference
Ameren Illinois has been using AMI for several years to collect energy usage data. Recently, teams across the company explored how that data could do more to help identify potential gas leaks faster.
Working with Data Analytics, Gas Dispatch and Operations developed a process that uses algorithms to flag unusual gas usage. By comparing a customer’s typical usage to the past 24 hours, the system looks for spikes that don’t return to normal levels.
If a significant increase is detected, the alert is reviewed by Gas Dispatch. When a potential leak is confirmed, a field technician is sent to investigate, following established safety procedures to protect the public.
This approach allows Ameren Illinois to use existing technology in a new way to help identify potential issues sooner and respond more quickly.
Without AMI detecting the anomaly, the situation may have gone unnoticed.
“If that system wasn’t in place, we wouldn’t have known about the leak when we did,” Millburg said. “This could have turned into a catastrophic event.”
A Shared Commitment to Safety
The incident also highlighted the strong coordination between Ameren Illinois and local first responders.
“It was a collaboration,” Keiser said. “Together, we handled it.”
Both emphasized that while technology plays a critical role, public awareness remains essential.
In this case, the homeowner had noticed an unusual odor in the days prior but didn’t recognize it as a warning sign.
“If you smell that rotten egg odor, don’t hesitate to call,” Keiser said.
Millburg echoed that message: “It’s important to act right away. We respond quickly, and there’s no charge.”
A Different Kind of Save
In sports, a great save is visible and immediate.
In Witt, the save came quietly — through data, training, teamwork and technology working exactly as designed.
No one was hurt. No homes were lost.
And what could have been a tragedy became a powerful example of how advanced metering and coordinated response are helping keep communities safe.
