Historic TX TDSP Per kWh Charges by Utility (as of Nov. 1, 2025)

How to Read This Chart

This line chart shows historical Transmission and Distribution Service Provider (TDSP) charges in Texas, measured in dollars per kilowatt-hour ($/kWh), by utility service territory. Each line represents a different TDSP — AEP Texas Central, AEP Texas North, CenterPoint, Oncor, and Texas New Mexico Power (TNMP) — allowing direct comparison of delivery charges over time. The horizontal axis shows the year, while the vertical axis shows the per-kWh delivery charge. Changes in each line reflect updates to regulated transmission and distribution rates approved through utility rate cases.

Why This Matters

TDSP charges make up a significant, non-competitive portion of customer electricity bills in Texas and apply regardless of which retail electric provider a customer chooses. Differences across utilities reflect variations in infrastructure investment, service territory size, storm hardening, and regulatory outcomes. Tracking TDSP charges over time helps consumers, regulators, and market participants understand structural cost pressures on retail electricity prices that are separate from energy market volatility. For policymakers and analysts, this data provides critical context for evaluating affordability, infrastructure investment needs, and long-term trends in the cost of delivering electricity across Texas.
