Oncor implemented new delivery charge tariffs in October and I'm seeing calculation errors across multiple retail electric providers. The new TDU charges are supposed to be revenue-neutral but several clients are seeing 20-30% increases in delivery costs. Has anyone else noticed problems with how REPs are implementing the new Oncor tariff structure? The PUCT approved these changes but something's not right in the billing.
Oncor delivery charges in Texas - new tariff structure causing problems
Georgia doesn't have retail choice but I've consulted on Texas accounts. Oncor tariff changes always cause billing chaos initially. Most REPs don't update their systems properly and customers get stuck with incorrect charges. Have you compared the new tariff schedules directly against the billing to identify specific calculation errors?
We don't have deregulation in Kansas but I've worked on Texas accounts before. Oncor delivery charge errors are common during tariff transitions. The key is getting detailed usage data and manually calculating what charges should be under the new tariffs. REPs often blame Oncor but it's usually their own billing system errors.
Did the manual calculations and found multiple errors. One client's REP was applying old demand charge rates with new energy rates, creating a hybrid billing structure that doesn't match any approved tariff. Another REP was double-charging certain delivery fees. Total overcharges identified so far exceed $45,000 across five accounts.
Texas deregulation creates so many opportunities for billing errors. Each REP interprets utility tariffs differently and PUCT oversight is limited. Document everything carefully because REPs will fight recovery claims even when errors are obvious. Have you contacted Oncor directly about the billing discrepancies?
Oncor says they're providing correct TDU data to REPs but won't investigate individual billing disputes. That's between customers and their REPs. Typical utility response - pass the buck to avoid responsibility. I'm filing complaints with PUCT against three REPs for systematic billing errors under the new tariff structure.
Texas retail electric market is a billing nightmare during tariff transitions. I've recovered over $200,000 this year alone from TDU delivery charge errors by various REPs. The key is understanding both Oncor's tariff structure and how each REP's billing system is supposed to implement it. Most REPs have inadequate quality control processes.
Randy's right about Texas being a billing disaster. The competitive market creates complexity that traditional regulated utilities don't have. Multiple layers of charges from TDUs, REPs, and ERCOT create numerous opportunities for calculation errors. Customers need professional auditing to protect themselves.
Update - PUCT ruled in favor of my complaints against two REPs. They're required to issue credits totaling $67,000 and fix their billing systems. The third REP is still fighting but their position is weak. Oncor tariff implementation errors are recoverable if you document them properly and pursue formal complaints when necessary.
