Green Mountain Review and Ratings

Last updated:

Green Mountain currently holds a Clear Energy Facts Score of 3.1 out of 5. This places them at rank #27 out of 42. Three factors were evaluated: plan quality, pricing transparency, and customer service.

 Green Mountain Energy is known for its long-standing focus on environmentally friendly electricity plans, offering options that support renewable energy while serving customers across Texas.

Green Mountain: What we like

  1. 100% renewable plans: All of their residential plans are offered as 100% renewable, which sets them apart from many other electricity providers in Texas.
  2. Environmental commitment: The company promotes reducing its environmental impact through everyday practices and sustainability-focused initiatives.
  3. Community support programs: They operate the Green Mountain Energy Sun Club®, which supports environmental and community-based projects.
  4. Referral rewards: Green Mountain Energy offers a referral program where both you and a friend can earn $50 in bill credits when signing up. Learn more here.
  5. Mobile App Experience: Green Mountain Energy offers a robust and well-rated mobile app that allows customers to manage payments, monitor electricity usage, view bills, and handle most account functions directly from their phone. The app provides a smooth and convenient experience for customers who prefer digital account management.
  6. Customer Service: As a part of the NRG Energy family, Green Mountain benefits from a large and well-established customer service infrastructure. The company offers 24/7 customer support via phone and online channels, making it a strong option for customers who prioritize reliable assistance.

Green Mountain: What we don’t like

  1. Declining customer sentiment: Over the past year, Google reviews have trended downward, with roughly one 1-star review for every two 5-star reviews. Common complaints mention higher-than-expected bills and aggressive cancellation notices, although company responses generally show an effort to assist customers.
  2. High cancellation fees: Early termination fees are higher than the current market average.
  3. Less competitive pricing: Their plans are generally less competitive than those offered by many other providers, including several options available on the Power to Choose marketplace.
  4. Strict late-payment penalties: Green Mountain Energy enforces a strict late-payment policy, including fees such as $20 per disconnection notice, $25 for returned payments due to insufficient funds, and a $30 Disconnect Recovery Fee. Customers should review the Terms of Service for full details.

How We Rate This Company

  • PUCT Rating: This is the official scorecard published by the Public Utility Commission of Texas (PUCT).
  • Plan & Rates: We evaluate each company’s electricity rates by giving more weight to clear True Fixed plans and less weight to other fixed-type plans, using average prices across different contract lengths. Companies with lower average rates score higher, and we exclude complex or gimmicky offers that require special equipment (like smart thermostats, EV devices, seasonal pricing, or “highest usage day” rewards).
  • Cancellation Fees: We compare each plan’s early termination fee against similar plans from other providers and normalize the data. Lower cancellation fees per contract term result in better scores.
  • Transparency: We check how consistently the provider displays prices across the main shopping channels Texans use: Power to Choose, the company’s own website, and Google Ads. If the prices match across these places, the transparency score goes up. If the company advertises one price but charges something different on its site, the score goes down.
  • CEF Score: The overall Clear Energy Facts score is a weighted average of these sub-scores, giving you a single number you can use to compare providers side by side.

Data note: Except for the PUCT Rating (which comes directly from the official PUCT scorecard), all CEF scores are calculated using real, up-to-date plan data from each provider. We recalculate these scores regularly using current Electricity Facts Labels and plan details — we don’t guess or use hidden assumptions.

Clear Energy Facts ratings focus on plan structure, transparency, and pricing. They do not include direct customer service scores. For that, we recommend checking recent Google Reviews and other independent sources, and being cautious with “star ratings” shown on sponsored comparison sites.

Transparency Review in Detail

5.0 /5.0

Transparency

Ranked #1 of 42 companies

Green Mountain obtains the highest transparency score because its rates and plans are largely consistent across all platforms, including its website, sponsored content on Google, and the Power to Choose marketplace. While minor differences between rates on Power to Choose and the company’s website can occasionally occur, these variations are typically less than 5%.

Customer Service Review in Detail

4.0 /5.0

PUCT complaint record

Ranked #6 of 42 companies

In this section we focus on the company’s customer service, using the official complaint data from the Public Utility Commission of Texas (PUCT).

1. PUCT scorecard rating. This score shows how this provider compares to other Texas electricity companies based on the number of customer complaints the PUCT receives about them.

2. What the PUCT scorecard means. The PUCT publishes a scorecard that rates Retail Electric Providers based on their complaint history. It compares a company's market share to its share of complaints filed with the state. Companies that resolve issues before customers feel the need to contact the PUCT receive higher ratings (5 Power Circles), while companies that frequently force customers to escalate issues receive lower ratings.

If a company does not have a PUCT rating (or we show “No rating”), it usually means there is not enough historical data for the PUCT to calculate a score. This typically happens when a company is new to the market or has a customer base too small to be statistically compared to larger providers.
