Paper mill in Tennessee on TVA's MSD rate claiming primary voltage service but I can't find any utility-owned transformers on the property. All the distribution equipment looks customer-owned. How do you verify if they're actually getting primary voltage and the associated discount?
Primary vs secondary voltage discount verification
TVA's definition of primary service is delivery at distribution voltage (4kV-35kV) without utility transformation. Look for the delivery point - if TVA delivers at 13.8kV or similar and the customer transforms it down, that's primary service. The discount reflects the customer providing their own transformation. Should be documented in the service agreement.
Thanks Claude. Found the service documents and they are getting 13.8kV delivery with customer transformation. The primary voltage discount is being applied correctly. Sometimes the simple explanations are the right ones!
Good catch on verifying the voltage level Darlene. Primary service verification is often overlooked but can be worth significant money if applied incorrectly. Always check the actual delivery voltage against what's being billed - utilities do make mistakes on service classifications.
