PROVIDER REVIEW
Green Mountain Review 2026
Green Mountain Energy has built its reputation as one of Texas’s pioneering renewable energy providers, offering 100% clean electricity plans since 1997. Customer sentiment data shows a 4.1 out of 5.0 star rating with a Net Promoter Score of 29, suggesting generally positive experiences among reviewers. On the regulatory side, the company logged 153 complaints with the Texas PUC over the past 12 months—below the 202-complaint average across tracked providers, though these raw counts aren’t adjusted for customer base size. Lower scores for billing clarity (26/100) and customer service (39/100) indicate areas where improvement is needed.

Complete Provider Analysis
The complaint breakdown reveals billing issues (70) and service/disconnection concerns (66) as the primary friction points for customers who escalate to regulators.

Positive Experiences
“They are allways very knowledgeable. And the bill is understandable, clear. No hidden fees. My bill has been $190 to $238. I was with txu since 1969, they just continued to increase there bill last one from txu was $350 . So I changed to green mountain, iam very happy with the company”
“Im absolutely so very proud my friend told me about Green Mountain Energy and how awesome they are. I was with the same company for over 12 years but knew must have been getting screwed and how right I was after talking to Green Mountain Energy. Ty for taking prompt immediate care and doing all the work for me. I look forward to many years of service to come.”
“I have had Green Mountain Energy for several years and continue to be very pleased with the service, the pricing, and customer service.”
“Their customer service went above n beyond to help us out. I would recommend this company anyway, anytime! If u was 100% customer service n expectations, this company is just that!!! I don’t ever recommend anyone or anything but this company has changed that by far!!!! Ty GME for everything!!!”
Critical Feedback
“I have been a loyal customer with GME for over 11 years. I finally moved to a new location and was planning to transfer service. After speaking with several agents, I was advised they don’t service my new address. I was devastated but had to cancel service after so many years and go elsewhere. Because of this, several agents told me I would not get hit with a cancellation fee. GME has always treated me right so I didn’t think my experience will change so quickly. I was hit with a bill over $800 after being advised I would not get a bill. I called and explained and was now told yes they do…”
“Terrible customer service. They don’t follow their own policies. They tried to convince me that the 24-48 hours they quoted for document verification was actually 24-48 “business hours” (which is not a thing anywhere). Customer service rep confirmed 3 times that I would 100% have service on Friday and I did not. They can’t turn on service over weekend so had to wait until Monday. DO NOT USE!”
“They will add on fees after your year contract is up and try to make it impossible for you to get out of your account. Beware of the balloon affect. They are not very transparent about it and will do everything they can to keep from telling you why your bill jumped 400.00$ making it look like your usage went up. Wasn’t home for a whole month and everything was off minus air being set to 75 and my bill was still $700.00!! Switched to a different company now my bill is only $250.00 $350.00 in the summer.”
FINAL VERDICT
Our Recommendation
Green Mountain: Conditionally Recommended
Solid renewable option with service room to grow
Green Mountain earns a conditional recommendation as a provider that delivers on its core renewable energy promise but shows inconsistency in customer experience. The 4.1-star rating and positive NPS of 29 indicate that most customers are satisfied overall. However, the customer service score of 39/100 and billing clarity score of 26/100 reveal meaningful friction points that prospective customers should consider. On the regulatory front, Green Mountain recorded 153 PUC complaints over the past year—actually below the 202-complaint average across the 15 providers we track, though this comparison isn’t adjusted for customer base size. Billing and service/disconnection issues account for most complaints. Green Mountain works well for customers who prioritize renewable energy sourcing and can tolerate occasional service hiccups. Those who need highly responsive support or crystal-clear billing may want to weigh alternatives.
Pros
- Strong 4.1 out of 5 star rating indicates good performance
- Positive customer sentiment with NPS score of 29
- PUC complaint count below average among tracked providers

Cons
- Customer service score of 39/100 needs significant improvement
- Billing transparency score of 26/100 indicates confusing communications

- Time-of-use billing details difficult for customers to understand
Best For
- Environmentally conscious customers seeking 100% renewable plans
- Customers comfortable managing accounts online with minimal support needs
- Those prioritizing green energy credentials over premium service
- Experienced energy shoppers who understand variable rate structures
- Homeowners willing to trade some billing simplicity for sustainability

Our Methodology
How We Calculate NPS Scores
Our scoring system analyzes customer reviews to provide an unbiased assessment of each electricity provider.
- Data Source: Google reviews of each provider
- AI Analysis: We score each review on a 1-10 recommendation scale and filter out spam, off-topic, and employee reviews
- Minimum Data: Providers with fewer than 25 scored reviews are shown as “Not yet rated”
- True NPS Calculation: We calculate Net Promoter Score as (% Promoters) – (% Detractors), where Promoters rate 9-10 and Detractors rate 1-6
- Star Rating: NPS scores are mapped to a 3.0-5.0 star scale for intuitive comparison
About “Billing Clarity” Scores
This score measures how clearly a provider communicates billing to customers—not billing accuracy. Texas electricity providers have robust, audited billing systems that are highly accurate.
- What we measure: Clarity of bill statements, proactive notifications, explanation of credits and charges, time-of-use rate communication
- Why it matters: Customers often report confusion about bills even when charges are correct—this score reflects how well providers help customers understand their bills
- PUC “billing complaints”: Most are about confusing statements or unexpected (but legitimate) charges, not actual billing errors
Pricing Data Collection
We collect electricity plan pricing daily from ComparePower’s live plan data.
- Data Source: ComparePower, the original Texas electricity consumer advocate
- Update Frequency: Prices are synced daily from every competitive Texas utility area (Oncor, CenterPoint, AEP Texas Central, AEP Texas North, TNMP, and Lubbock Power & Light)
- Usage Levels: We display pricing at 500, 1,000, and 2,000 kWh/month to show how rates vary by consumption
- Coverage: 17 major retail electricity providers in the Texas deregulated market
PUC Complaint Data
Complaint data provides insight into provider accountability and customer issues.
- Data Source: Texas Public Utility Commission (PUC) official complaint records
- History: Monthly complaint data since January 2022
- Categories: Billing, Service & Disconnection, Slamming/Cramming, and Other
- License Holders: The PUC reports complaints per license holder, so brands that share a license share the same counts
- Size: Counts are not adjusted for the number of customers a provider serves
- Update Frequency: Monthly updates as new PUC data becomes available
