Just finished an audit on a 180-unit complex here in Denver that's been master-metered by Xcel Energy since 2015. Found a systematic billing error where they've been applying the wrong rate schedule for four years. Property was being billed under Schedule SG (Small General) instead of LGS (Large General Service) despite consistently exceeding the 30kW demand threshold. The rate difference has cost this property $47,000 in overcharges. Xcel initially pushed back claiming the account was set up correctly, but the meter data doesn't lie.
Xcel Energy apartment complex billing error - $47K overcharge
Carl, that's a massive overcharge! How did Xcel justify keeping them on SG for four years? Here in Milwaukee, We Energies automatically moves commercial customers to the appropriate rate when they exceed thresholds for three consecutive months. Did the property ever request a rate analysis?
Linda, that's the frustrating part. The property management company just paid the bills without question. Xcel's explanation was that the customer never requested a rate change, so they kept billing under the original schedule. But their own tariff says accounts should be billed under the most advantageous rate - which clearly wasn't happening here.
Carl, I see this all the time with OG&E here in Oklahoma. Utilities love when customers don't pay attention to rate schedules. Did you get the full refund or did Xcel try to limit it to 12 months? Most utilities have policies limiting retroactive adjustments.
Steve, Xcel initially offered only 12 months, but I pushed back with their own tariff language about billing under the most advantageous rate. After involving the Colorado PUC informally, they agreed to the full four-year refund. The key was showing that every single month exceeded the SG threshold, making the original rate assignment clearly inappropriate.
Great result Carl! This is why apartment complex audits are so valuable. Property managers often treat utility bills like rent - just pay whatever shows up. I've found similar issues with FPL down here in Florida, especially on older master-metered properties where the rate was set decades ago and never reviewed.
This highlights the importance of annual rate schedule reviews. I tell all my apartment clients to request rate analyses every year, especially if their usage patterns have changed. Utilities won't volunteer to put you on a better rate - you have to ask for it.
Clyde's right about annual reviews. I've also seen the opposite problem - properties getting moved to higher rate schedules unnecessarily. Had a Wisconsin property where We Energies moved them to a demand-based rate after one month of high usage due to equipment malfunction. Took six months to get them back on the right schedule.
Dan, that's exactly why I always recommend written documentation for any rate schedule changes. NorthWestern Energy here in Montana has made similar "automatic" moves that weren't in the customer's best interest. Having proper documentation makes reversals much easier.
All great points. I've now added quarterly rate schedule verification to my standard apartment audit checklist. This Xcel case could have been caught much earlier with regular monitoring. The property is now saving about $800 monthly on the correct LGS rate.
Carl, curious about the demand characteristics that triggered the rate issue. Was this primarily HVAC load or did they have other major equipment? I'm auditing a similar Cincinnati complex with Duke Energy and want to make sure we're on the right schedule from the start.
Chuck, it was primarily central HVAC plus pool equipment and common area lighting. Peak demand was running 45-65kW depending on season, with summer peaks consistently above 60kW. The SG rate was capped at 30kW, so they were paying hefty overage charges instead of the more economical LGS demand structure.
This thread should be required reading for property managers. I'm seeing similar issues with TEP here in Arizona - old master-metered properties on legacy rates that haven't been reviewed in years. The savings potential is enormous if you know what to look for.
Omar's absolutely right. Carl, would you be willing to share your rate schedule audit checklist? I think a lot of us could benefit from a systematic approach to identifying these issues. Property managers need education on this stuff - they're leaving money on the table everywhere.
