Selectra editorial verdict
Green Mountain Energy is the most credible 100% renewable retail brand in the US, with a 25+ year track record, Green-e certification on every plan, and NRG's balance sheet behind it. For households who want to make a verifiable green-electricity choice without installing rooftop solar, it is the cleanest single decision in the market. The trade-off is price: you will typically pay 1-3 ¢/kWh more than a standard fixed plan. If your priority is purely lowest unit cost, look elsewhere; if you want a 100% renewable label that holds up to scrutiny, Green Mountain is the benchmark.
Pros
- First and longest-running 100% renewable retail electricity supplier in the US (since 1997).
- Every kilowatt-hour sold is matched with Green-e certified RECs — the gold-standard third-party renewable verification.
- A+ BBB rating with long-standing accreditation.
- Backed by NRG Energy (NYSE: NRG) since 2010 — operational scale and balance-sheet stability.
- SolarSPARC add-on directs voluntary contributions to community-solar projects in low-income neighbourhoods.
- Customer-portal and mobile-app experience is solid; 24/7 chat in Texas.
Cons
- Rates carry a premium of roughly 1-3 ¢/kWh over standard fixed plans — you pay for the 100% renewable guarantee.
- Texas plans include a $9.95 monthly base charge that hurts low-usage households disproportionately.
- Early-termination fee on the 36-month Solar plan ($295) is high — only commit to long terms if you are confident in staying put.
- 100% renewable means RECs, not physical delivery — the electrons in your wall still come from the local grid mix. The "Pollution Free" branding can over-promise this.
- Limited footprint: only 6 states, all electric (no natural gas).
Common questions about Green Mountain reviews
Green Mountain Energy reviews — answers
Reliability is best judged across multiple sources, not one platform. Trustpilot and Google reviews skew negative (dissatisfied customers post more often), while BBB ratings reflect complaint handling. The most balanced check: look at the BBB letter grade for complaint resolution, scan recent (last 6 months) Trustpilot reviews for recurring themes, and compare Green Mountain's unit rate against your utility's price-to-compare before signing up.
Retail energy is a complaint-driven category — customers rarely write reviews when their bill arrives correctly, but a billing dispute, a variable-rate surprise, or a renewal price increase often triggers a 1-star review. The same dynamic affects every US retail-energy brand. The BBB complaint-resolution rate and the state public-utility-commission complaint reports (often public) tend to be more representative than aggregate review scores.
