Dealing with a weird AMI issue down here in Huntsville. Alabama Power installed smart meters on my client's facility last year. Now we're seeing random usage spikes that don't correlate with actual operations. Last month showed 15,500 kWh on November 12th when the facility was closed for maintenance. Alabama Power claims the AMI data is accurate but something's clearly wrong. Anyone else seen AMI meters report false high readings due to data transmission errors?
Alabama Power AMI meter showing usage spikes - data corruption?
Patricia, that sounds like classic AMI data corruption. Duke Energy Ohio had similar issues when they first rolled out smart meters. Random usage spikes on days with no activity usually indicate communication errors between the meter and the utility's collection system. The meter might be transmitting corrupted data packets. Have you requested hourly usage data to pinpoint exactly when these spikes occur?
Chuck's right about requesting hourly data. I've seen this with MLGW's AMI rollout here in Memphis. Usually the meter records correct usage but data gets scrambled during wireless transmission. The hourly breakdown will show if usage spiked during a specific hour or if it's spread across the day. If it's all in one hour, that's definitely transmission error.
Randy and Chuck are spot on. Pacific Power had this exact problem during their AMI deployment. Meters would occasionally transmit duplicate readings or corrupted data packets showing impossibly high usage. The fix usually requires the utility to flag the meter for manual validation and possibly firmware updates. Don't let Alabama Power brush this off as "accurate data."
Thanks everyone. I requested the hourly data and you're absolutely right - the entire 15,500 kWh spike occurred between 2:00-3:00 AM on a day when the facility had no power consumption except emergency lighting. That's physically impossible. Alabama Power's AMI team is now investigating the meter's communication module. Apparently this model has known firmware issues.
Patricia, document everything with Alabama Power's AMI investigation. Consumers Energy had similar firmware problems and initially tried to blame customers for the billing errors. Having detailed records of the utility acknowledging meter problems helps if you need to dispute future bills. These AMI systems are great when they work properly but create massive headaches when they don't.
Tina's absolutely right about documentation. I had a similar case with IPL where AMI meters were double-reporting usage during certain weather conditions. Took six months to get them to admit the problem and issue credits. The key is proving the pattern of errors and getting the utility to acknowledge equipment defects in writing. Makes future disputes much easier to resolve.
Patricia, any final update on your Alabama Power AMI case? These firmware issues seem to be industry-wide problems. Would be helpful to know how they resolved it for future reference when dealing with other utilities experiencing similar AMI data corruption issues.
