I've been exploring the power quality monitoring capabilities of LG&E's new AMI meters here in Louisville. These smart meters can track voltage variations, power factor, harmonics, and outage events in addition to kWh/demand. I'm wondering if this data represents a new service opportunity for utility bill auditors. Several commercial clients have asked me to review power quality issues that might be affecting their equipment efficiency or causing damage. Has anyone else started offering PQ analysis services using AMI data?
AMI power quality data - new revenue opportunity for auditors?
Jack, that's an interesting angle. TVA's smart meters here in Tennessee can detect voltage sags and swells, but getting access to that data has been challenging. They say it's available but you have to request it specifically and pay extra fees. I've had manufacturing clients complain about equipment shutdowns that correlate with power quality events, but without the AMI data, it's hard to prove the utility's system was the cause. What kind of PQ data is LG&E providing?
Terry, LG&E provides voltage magnitude, power factor by phase, and total harmonic distortion on request. They charge $50 for historical data exports and $25/month for ongoing monitoring. I've found several cases where voltage variations were causing motor efficiency losses that cost more than the PQ monitoring fees. One client was seeing 3-5% higher energy consumption during voltage sag periods - that's real money on a large manufacturing operation.
This could be huge for auditors willing to expand their services. Duke Energy's AMI system here in Charlotte can identify capacitor bank switching events, transformer tap changes, and even detect deteriorating connections through impedance monitoring. I've been thinking about partnering with an electrical engineer to offer comprehensive power quality audits. The challenge is learning how to interpret all this new data - it's way beyond traditional kWh auditing.
Derek raises a good point about needing engineering expertise. I've been taking courses on power quality analysis to understand THD, voltage unbalance, and flicker measurements. FirstEnergy's AMI data showed one of my clients had 8% voltage unbalance that was causing premature motor failures. The client recovered $15,000 in equipment replacement costs from FirstEnergy once we documented the power quality violations with their own meter data.
Jim, that's exactly the kind of case that shows the revenue potential. I've started advertising power quality audits as an add-on service here in San Antonio. CPS Energy's AMI system detected harmonic distortion at a data center that was causing UPS failures. We helped the customer document $23,000 in equipment damage and ongoing efficiency losses. The PQ audit fee was only $1,500 but led to a $75,000 rate optimization project. Smart meter data is opening up opportunities we never had with mechanical meters.
