"CPL is your local utility" was true 25 years ago. It is wrong today.
Many guides still describe CPL as the south Texas utility that "sends you power". That has not been accurate since the 2002 Texas retail market opening. The single company called Central Power and Light split in two: the wires business became AEP Texas Central, a regulated transmission and distribution utility (TDU); the customer-facing retail business became CPL Retail Energy, a competitive retail electricity provider (REP).
The brand kept the name. The economics did not. CPL Retail Energy today is one of many REPs competing for your account; its rates are set by its parent, Direct Energy, which has been owned by NRG Energy since January 2021. It does not own the wires. It does not read your meter. It does not respond to outages. AEP Texas does all three.
The practical consequence: comparing CPL to "the utility" is a category error. CPL competes with Reliant, TXU, Gexa, Green Mountain and dozens of smaller REPs. The right question is not "should I leave the utility?", it is "is CPL's current Electricity Facts Label competitive at my usage and in my TDU zone?".
Where CPL sits on your Texas bill.
Every Texas bill has three layers. Only the first one is the REP. Knowing which line belongs to whom is the difference between a smart switch and a wasted hour.
Layer 1, Shoppable
Supply, this is CPL
The cents-per-kWh price for the electricity itself, plus any REP base charge. This is what CPL Retail Energy controls and what every comparison should focus on.
Layer 2, Regulated
TDU delivery, AEP Texas
In south Texas your TDU is AEP Texas Central. Your wires, poles, transformers and meter belong to them. CPL has no control over this line; the PUCT sets it in a rate case.
Layer 3, Mandatory
Fixed fees, taxes, riders
A TDU monthly customer charge (around $9 in AEP Central), any REP base charge, state sales-tax-equivalent gross receipts charges, and PUCT assessment. You pay these no matter who supplies your power.
When CPL advertises a rate, that rate is layer 1 only. Your total bill always includes layers 2 and 3, that is the same for every Texas REP, and it is why an EFL at YOUR usage is the only honest comparison.
CPL bill lines, decoded.
A CPL bill in south Texas can show eight or more line items. Here is what each one really is, who sets it, and whether shopping a different REP would change it.
| Line on your bill | What it really is | Who sets it | Shoppable? |
|---|---|---|---|
| Energy charge | Layer 1, supply per kWh | CPL Retail Energy | Yes |
| Base / monthly service charge | REP fixed fee (if any) | CPL Retail Energy | Yes |
| Bill credit | Plan-specific usage rebate | CPL Retail Energy | Yes |
| TDU delivery (per kWh) | Layer 2, wires charge | AEP Texas, approved by PUCT | No |
| TDU customer charge | Monthly wires connection fee | AEP Texas, approved by PUCT | No |
| Gross receipts reimbursement | State tax pass-through | State of Texas | No |
| PUC assessment | State regulator funding fee | PUCT | No |
| Sales tax | State and local sales tax | State and city | No |
Only the top three rows move when you switch from CPL to a different Texas REP. Everything else is identical regardless of brand.
"Switching to CPL saves 15%" is really about 9% off your bill.
In a typical Texas residential bill, only about 55-65% of the total is supply. The rest is TDU delivery, fixed charges and taxes that no REP, CPL or otherwise, can change.
If CPL's plan is 15% cheaper on the supply rate than your current REP, the actual saving on the total bill is closer to 8-10%. That can still be worth doing. It is also a long way from the headline.
Two neighbors in Corpus Christi on the same CPL plan, with the same monthly usage, can still pay different totals: their TDU charges, customer charges, and city sales tax can all differ slightly.

How the CPL name survived deregulation, and what it really means today.
Four moments turned a single south Texas utility into the brand you see on a CPL Retail Energy plan in 2026.
1916 to 1997, Central Power and Light
Central Power and Light Company is the vertically integrated investor-owned utility for south Texas: it generates power, owns the wires, reads the meter and bills the customer. It is part of Central and South West Corporation (CSW) for most of this period.
1997 to 2000, AEP buys CSW
American Electric Power announces and then completes the acquisition of Central and South West Corporation. CPL becomes an AEP operating company. The name on the trucks still says "CPL".
1999 to 2002, Texas SB7 and the retail open
Texas Senate Bill 7 splits utilities into a regulated wires business and a competitive retail business. On 1 January 2002 the retail market opens. CPL's wires become AEP Texas Central; CPL's retail customer base is moved to a new affiliated REP, CPL Retail Energy.
2002 to today, Direct Energy, then NRG
The CPL Retail Energy brand passes to Direct Energy, then to NRG Energy when NRG closed its $3.625 billion acquisition of Direct Energy in January 2021. Today the CPL trucks belong to AEP Texas; the CPL bills belong to NRG.
If you have lived in Corpus Christi, McAllen, Laredo or the Rio Grande Valley for thirty years, you have paid bills with "CPL" on them the whole time. The companies behind that name have changed four times.
How south Texas households quietly overpay on CPL.
Five patterns we see again and again in CPL bill reviews. Each one is fixable in under thirty minutes.
If your power goes out, do not call CPL.
CPL Retail Energy sells you the electricity. It does not own the wires and it cannot dispatch a crew. In south Texas the wires belong to AEP Texas, and AEP Texas runs the outage line.
Report outages to aeptexas.com/outages, by AEP Texas SMS, or by the published AEP Texas residential outage number on your bill. CPL customer service can answer billing questions but will redirect you to AEP for anything physical.
How to actually evaluate a CPL plan in 2026.
Look up your TDU
South Texas is AEP Texas Central. Confirm yours on the last bill: every Texas bill names its TDU.
Find your real monthly kWh
Pull 12 months of usage. Texas REP plans price very differently at 500, 1,000 and 2,000 kWh.
Pull the CPL EFL
The Electricity Facts Label shows the average rate at three usage tiers, the base charge, the bill-credit rules, and the ETF.
Cross-check on Power to Choose
The PUCT-run site powertochoose.org lists every certified REP plan in your ZIP, with the same EFL.
Compute all-in dollars
Multiply: supply × your kWh, plus TDU delivery × your kWh, plus all fixed fees. That single number, side by side, is the only honest answer.
If you struggle to pay
Texas LIHEAP runs as CEAP via TDHCA. CPL must enroll eligible households in the state low-income discount on request.
Common questions about CPL Energy.
No. The original Central Power and Light Company was a vertically integrated utility that owned the generation, the wires and the customers in south Texas. Texas SB7 split that single company in 2002. The wires business became AEP Texas Central, a regulated TDU. The customer-facing retail business became CPL Retail Energy, a competitive REP. They share a heritage and a name fragment; they are different companies with different regulators and different price-setting rules today.
CPL Retail Energy is a brand of Direct Energy, which is a subsidiary of NRG Energy, Inc. NRG closed its $3.625 billion acquisition of Direct Energy in January 2021. Before that, Direct Energy was owned by UK utility Centrica from 2000. Direct Energy was originally founded in Toronto in 1986.
No. AEP Texas Central owns the wires, poles, transformers and meter in south Texas. They deliver every kWh consumed in their service territory regardless of which REP you choose. CPL Retail Energy only handles supply, billing and customer service. For outages and meter problems you contact AEP Texas, not CPL.
CPL plans are competitive in some months and not in others, like every Texas REP. The only honest comparison is the Electricity Facts Label at YOUR monthly kWh and YOUR TDU zone. powertochoose.org lists every certified plan in your ZIP code side by side. Always check the rate after any introductory period, the bill-credit thresholds, and the Early Termination Fee.
CPL fixed-term plans typically carry an ETF of $150 to $295, varying by plan and term length. The exact figure is on the Terms of Service for each plan. Texas Public Utility Commission rules waive the ETF if you move out of the service territory or within ERCOT and provide a forwarding address and supporting documentation within a defined window.
Yes. Texas runs LIHEAP as the Comprehensive Energy Assistance Program (CEAP) through the Texas Department of Housing and Community Affairs. Eligible households apply through a local sub-recipient agency; CEAP can pay arrears and a portion of ongoing bills. CPL, like every Texas REP, must process the enrollment when the application is approved.
