1. Who Is Green Mountain Energy and Who Owns It?

Founded in Vermont in August 1997 to offer renewable retail electricity in deregulated markets, Green Mountain Energy relocated its headquarters to Austin, Texas in 2000 ahead of ERCOT retail deregulation. In November 2010, NRG Energy, Inc. acquired Green Mountain Energy Company for approximately $350 million. It operates today as NRG Energy’s dedicated 100% renewable retail brand.

Operating History in ERCOT: Holding PUCT REP Certificate #10009 since the start of Texas retail choice in 2002, Green Mountain Energy was the first Texas retail provider dedicated exclusively to renewable electricity products and has helped finance wind and solar installations across Texas.

2. Is Green Mountain Energy a Retail Provider or a Delivery Utility?

Green Mountain Energy is a Retail Electric Provider (REP), not a local delivery utility. If you enroll with Green Mountain Energy in Dallas, Fort Worth, Houston, Corpus Christi, or Lubbock, Green Mountain 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 Green Mountain Energy Offer?

• 100% renewable fixed-rate plans (12–24 months)
• Time-of-use renewable plans
• EV charging & night-rate plans
• Solar buyback plans

Renewable Energy Offerings: Every residential plan offered by Green Mountain Energy is 100% renewable, backed by wind and solar Renewable Energy Certificates (RECs) disclosed on the plan’s Electricity Facts Label.

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

• Billing & Payment Policies: Supports autopay and paperless billing discounts on select plans (such as Pollution Free e-Plus Preferred, where the EFL specifies whether autopay/e-bill enrollment is required to maintain the preferred rate).
• Early Termination Fee (ETF) Policy: Typically assesses a flat early termination fee (commonly $150 for 12-month plans and $295 for 24-month plans, as stated on each plan’s EFL), waived when moving to a new address with proof of move-out.

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

Green Mountain Energy is a sister company to Reliant Energy, Direct Energy, and Discount Power under parent NRG Energy, Inc. While every Green Mountain plan is 100% renewable, several other Texas REPs (including Chariot Energy, Rhythm Energy, and Gexa Energy) also sell 100% REC-backed renewable plans—often at lower cents-per-kWh rates. Always check the EFL to verify whether a 'Preferred' rate depends on continuous autopay and paperless billing.

Pre-Enrollment Checklist for Any Green Mountain 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.
