What Are TDSP Delivery Charges on a Texas Business Electricity Bill?
TDSP delivery charges on a Texas business electricity bill cover the cost of transmitting and distributing power from the grid to your facility. These charges are set by the PUCT, vary by TDSP (Oncor, CenterPoint, AEP Texas, TNMP), and include both volumetric (per kWh) and demand-based (per kW) components. While non-negotiable, they are subject to audit and can be overcharged. A free Energy Health Check can identify errors and recover overpayments.
