Need some guidance on meter testing procedures with Ameren Missouri. I have a large industrial client whose bills have been trending upward without corresponding increases in production. Ameren says their meter is reading accurately, but I'd like to request formal testing. Does anyone know Ameren's specific procedures for meter testing requests? Do they charge for testing if the meter is found to be accurate?
Meter Testing Protocol - Ameren Missouri
John, Ameren Missouri generally follows standard utility practice - they'll test the meter for free if it's found to be inaccurate (usually >2% error), but charge around $500-800 if it tests within tolerance. You can request testing through their business customer service line. Make sure you document any unusual billing patterns or energy usage anomalies to strengthen your case for testing.
Linda's information is spot on. I'd add that before requesting meter testing, make sure you've ruled out other causes like rate changes, seasonal adjustments, or operational changes at the facility. Ameren will ask what evidence you have that the meter might be faulty. If you do proceed with testing, request that your client or a representative be present during the test - it's usually allowed and gives everyone confidence in the results. Also document the current meter readings and serial numbers before testing begins.
