Just wanted to share a success story for anyone dealing with power factor penalty disputes. Xcel Energy here in Minneapolis was charging us $2,400/month in PF penalties on our Schedule A-15 service. We knew something was wrong because our plant PF monitoring showed consistent 0.92-0.95 readings. After six months of back and forth, we finally got them to admit their revenue meter had a faulty CT. Total refund was $14,400 plus they waived future penalties during the meter replacement. The key was getting independent power quality data and being persistent with the regulatory complaint process.
Xcel Energy Minneapolis - disputed PF penalty resolution
Christine, that's awesome! PG&E tried to pull similar nonsense with us in San Jose. How did you get Xcel to finally admit the meter was bad? We're dealing with Schedule E-19 penalties that don't match our internal monitoring. PG&E keeps insisting their equipment is fine but the readings make no sense.
Pete, the breakthrough came when we hired an independent power quality consultant to do a week-long monitoring study. The consultant's data showed perfect correlation with our internal meters but huge discrepancies with Xcel's billing data. We filed a formal complaint with the Minnesota PUC and included all the monitoring reports. Xcel finally agreed to test their meter rather than go through a full regulatory hearing.
What kind of consultant did you use? We're having similar issues with Ameren Missouri and could use some professional backup. The utility keeps claiming our power factor is 0.78 but our Schneider monitoring system shows 0.88-0.91 consistently. It's like they're reading from a different planet.
Elmer, I used Power Quality Engineering out of Minneapolis. They specialize in utility dispute work and have good relationships with the regulatory agencies. Cost was about $8,000 for the full monitoring study and expert testimony, but we recovered that in the first month of refunds. The key is getting someone with PE credentials who can testify if needed.
Christine, did Xcel try to charge you for the meter testing? Duke Energy here in Cincinnati wanted $1,200 just to test their meter when we disputed penalties. Seems like they make it expensive hoping you'll just pay the penalties instead of fighting.
Cecilia, yes they tried to charge us $800 for meter testing initially. But once we filed the PUC complaint, they had to eat that cost as part of the dispute resolution. The Minnesota PUC rules say if the meter is found to be defective, the utility pays for testing. That's why having good documentation and following the formal complaint process is so important.
This gives me hope for our Georgia Power dispute. We've been fighting $1,800/month in Schedule PL penalties for eight months. Georgia Power claims our PF is 0.81 but our Satec monitoring shows 0.89 average. I'm going to look into hiring a consultant like you did. Did you have to shut down during the monitoring period?
Eleanor, no shutdown required. The consultant installed portable monitoring equipment on our service entrance - took about 2 hours. The monitoring ran for 7 days continuously and captured all our normal operating patterns. Make sure you get someone who understands utility billing procedures, not just power quality measurement. Half the battle is interpreting the tariff language correctly.
Great thread Christine! Duke Energy Charlotte tried similar tactics with us. The key point about getting PE-certified consultants is spot on. Utilities take you much more seriously when you have professional engineering backup. We ended up settling our dispute for $22,000 refund rather than going to full hearing, but having credible expert testimony was crucial to getting them to negotiate.
This is exactly the kind of detailed case study we need more of on the forum. Christine, would you be willing to share your consultant's monitoring report template (with sensitive data redacted)? Having a standard format for power factor dispute documentation would help other members. I can host it in the resource library if you're interested.
