2. Is Cirro Energy a Retail Provider or a Delivery Utility?

Cirro Energy is a Retail Electric Provider (REP), not a local delivery utility. If you enroll with Cirro Energy in Dallas, Fort Worth, Houston, Corpus Christi, or Lubbock, Cirro Energy does not own the poles, wires, or smart meter at your home. Your local Transmission and Distribution Utility (Oncor, CenterPoint, AEP Texas, TNMP, or LP&L) delivers the electricity, reads the meter, and restores power after storms. Regulated TDU delivery charges are passed through on your bill at the exact same PUCT-approved rate regardless of which retail provider you choose.

3. What Types of Electricity Plans Does Cirro Energy Offer?

Renewable Energy Offerings: Includes standard statewide renewable content with optional renewable add-ons.

4. Billing Practices, Cancellation Fees, and Conditions to Check

5. What Cirro Energy’s Ownership Means for Customers (Before You Enroll)

Cirro Energy is owned by NRG Energy, Inc. While Cirro Energy itself is not currently active in Power Hopper’s checkout feed, four of its corporate sister brands under NRG Energy—Reliant Energy, Direct Energy, Green Mountain Energy, and Discount Power—are active in Power Hopper’s comparison feed.

Pre-Enrollment Checklist for Any Cirro Energy Plan:

  1. Open the plan’s official Electricity Facts Label (EFL) and compare the 500 kWh, 1,000 kWh, and 2,000 kWh average price rows. If the 1,000 kWh price is 4¢–6¢ lower than the 500 kWh and 2,000 kWh rows, the plan uses a usage-threshold bill credit that can increase bills in mild or peak months.
  2. Confirm whether the advertised energy charge requires continuous enrollment in AutoPay and paperless billing.
  3. Check whether the early cancellation fee is a flat dollar amount (e.g., $150) or per remaining month (e.g., $15–$20 × months left), and use our Switching Break-Even Calculator if you are leaving an existing contract.
  4. Mark your contract expiration date on your calendar so your account does not roll onto a high month-to-month holdover rate when the fixed term ends.
