Positive Experiences
Verified
“I switched because with Green Mountain I never have had any issues and excellent customer service. I signed up with a Rep outside in front of HEB. I am so proud I changed. I’ve had Reliant, Direct Energy. Green Mountain had a cheaper offer. They always call me for updates or if I need anything. Some months usage is less and glad for that. They call me if I have any questions. To me there’s more prestige with HEB and Green Mountain Energy. They follow-up every year. I’m impressed.”
Verified
“My experience with this company has been great so far. Customer service was excellent yesterday – I had all my questions answered in a timely manner and the best part is I wasn’t transferred to different departments. I spoke with one person, resolved my issue, and I was done. Great job to the young man I spoke with to resolve my issue about my bill!”
Verified
“They are always very knowledgeable. And the bill is understandable, clear. No hidden fees. My bill has been $190 to $238. I was with TXU since 1969, but they just continued to increase their bill – last one from TXU was $350. So I changed to Green Mountain and I am very happy with the company.”
Verified
“Great customer service, understanding of late payments, overall the best. Been with them 5+ years.”
Verified
“I was very close to moving my service to another company but Green Mountain’s customer service configured a deal I could not refuse. I strongly suggest calling customer service before signing with another provider.”
Critical Feedback
Verified
“DO NOT USE THIS COMPANY! Called almost 2 months in advance to have my service canceled only to find out the employee didn’t actually cancel my service. Got a bill for a place I don’t even live at anymore and when I called to see why I’m being charged, the supervisor admitted the employee made a mistake by not canceling the policy by my move out date, but it doesn’t matter because energy was still being used. I don’t even know why they have customer service because they are not helpful.”
Verified
“Worst experience. I called three times before my move-out and clearly informed them that I would not be continuing the service. However, a week after moving out, I received an email showing my weekly usage and realized I had been enrolled in a month-to-month plan without my knowledge. I contacted customer service and asked them to check the call records, as I had already spoken to an agent and confirmed the cancellation. I was never informed that I would be automatically enrolled in a monthly plan.”
Verified
“Have had this company for years up until now. Their rates used to be more reasonable but have recently skyrocketed. The kWh rate on my most recent bill was 19.2 cents, which is crazy. There’s fixed rate plans from other companies that are around 12.5 cents. Charging over 50% more for power is crazy and they need to work on getting their rates more competitive.”
FINAL VERDICT
Our Recommendation
Green Mountain: Conditionally Recommended
Solid renewable option with billing concerns
Green Mountain Energy earns a conditional recommendation based on mixed but generally positive indicators. The provider maintains a 4.1-star Google rating and a positive NPS of 31, suggesting most customers are satisfied with their overall experience. Their regulatory record is encouraging, with 100 PUC complaints over the past 12 months—below the industry average of 120—indicating relatively fewer escalated disputes. However, the data reveals notable weaknesses: a customer service score of 39/100 suggests room for improvement in support interactions, while a billing clarity score of just 26/100 points to potential confusion around charges and invoices. For customers who prioritize Green Mountain’s established reputation in renewable energy and can tolerate occasional billing complexity, this provider offers a reasonable choice. Those who require straightforward billing or responsive customer support may want to explore alternatives.

Our Methodology
How We Calculate NPS Scores
Our proprietary scoring system analyzes thousands of customer reviews to provide an unbiased assessment of each electricity provider.
- Data Source: Online Reviews from verified customers
- AI Analysis: We analyze each review to distill sentiment and filter out incentivized reviews, bot-generated content, and review bombing attempts
- 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 directly from official sources to ensure accuracy.
- Data Source: ComparePower, the original Texas electricity consumer advocate
- Update Frequency: Prices are synced daily from all 5 TDSP territories
- Usage Levels: We display pricing at 500, 1000, and 2000 kWh/month to show how rates vary by consumption
- Coverage: All 17 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: 46+ months of historical complaint data (January 2022 – Present)
- Categories: Billing, Slamming/Cramming, Quality of Service, Disconnection, and Other
- Update Frequency: Monthly updates as new PUC data becomes available
