The offer: a variable price you can leave
Picture a month-to-month plan. You pay a price per kWh that Green Mountain sets each month, and you can leave at any time with no fee. That is the Pennsylvania plan whose terms we could read. The company also sells a 12-month fixed plan, but we could not open its terms, so we cannot say what that plan costs or what leaving it costs. Green Mountain sells in Texas too, and we review that company on our Texas page.
No cancel fee. An A+ at the BBB and 2.91 complaints per 10,000 homes in 2024. A 100% renewable product. Owned by NRG Energy, with audited accounts.
A variable price about 38% above the price to compare in September 2026. A 2022 PUC penalty. Arbitration and a class-action waiver.
Each bar is that part's points as a share of the most it can earn.
Check your Green Mountain price
Your bill shows what Green Mountain charges you per kWh. Pick your utility and type that price. The tool puts it next to your utility's price to compare, which is what you would pay with no supplier, and shows the gap for a month and a year.
This covers supply price only and is not a bill. The yearly figure assumes your variable price stays put, which it may not. Nothing you enter is kept.

Is Green Mountain's price a good one?
Not on the numbers we read. Green Mountain is not on PA Power Switch, the state's shopping list. Its offers load by script on its own site, so we could not read a 12-month price. We used its own September 2026 variable price list instead.
| Price | PPL area | PECO area |
|---|---|---|
| Green Mountain variable price, its own list, Sept. 2026 | 18.0¢ | 16.2¢ |
| Price to compare | 13.079¢ | 11.759¢ |
| Green Mountain as a share of the price to compare | 137.6% | 137.8% |
That is about 4.9¢ a kWh more in PPL's area and 4.4¢ more in PECO's. At 1,000 kWh a month, each 1¢ of gap is about $10, so the gap is roughly $49 and $44 a month. Some of it may pay for the 100% renewable product. Our green plan guide explains what that buys. Utilities charge 13.079¢ in PPL's area and 11.759¢ in PECO's today. Every utility is on the price to compare page.
A variable price is not locked. It can go up or down next month without a new contract, and you may not hear about it before the bill comes. Read your bill each month.
Can you trust Green Mountain in Pennsylvania?
Yes, it is licensed. We read its Pennsylvania license record, docket A-2011-2229050, on Oct. 16, 2026. A license does not make a price fair, and the price section shows the gap.
Green Mountain's score is built from six parts. Each is listed with the record behind it.
| Category | Points | Evidence |
|---|---|---|
| Complaints to the state | 25 / 25 | The PUC's 2024 report counted 9 complaints under "Green Mountain Energy." Divided by 30,875 homes served (EIA-861, 2024), that is 2.91 per 10,000 homes. Under 5 earns 25 of 25 points. |
| BBB rating | 5 / 5 | A+, not BBB accredited, read on October 16, 2026. That earns 5 of 5 points. |
| Fines and penalties | 12 / 20 | One Pennsylvania penalty in the last 10 years: $156,000, entered February 24, 2022. It costs 8 points, so 12 of 20. |
| Contract fairness | 14 / 20 | There is no cancel fee (5 of 5) and no extra fees (4 of 4). The contract has an arbitration clause and a class-action waiver (0 of 4). We could not read the 12-month plan's terms (2 of 4). No cancel fee means you can leave at any time (3 of 3). |
| Price | 0 / 20 | The variable price was 18.0¢ in PPL's area and 16.2¢ in PECO's in September 2026. The October reference prices to compare behind our score are 13.079¢ and 11.759¢. That makes it 137.6% and 137.8%, an average of 137.7%, which earns 0 of 20 points. |
| Time in business | 6 / 10 | Licensed June 10, 2011 for business and February 16, 2012 for homes (15 years), which earns 4 of 6 points. No Green Mountain bill-help program turned up (0 of 2). Audited accounts via NRG earn 2 of 2. |
What this score rests on
Every category is worked out from public records. Where a record does not exist, a fixed default number of points is given, and the label says so. A default is not a finding about the company.
- Complaints to the state 25 of 25 points Record foundThe state's 2024 complaint count and the federal count of homes served give a rate.
- BBB rating 5 of 5 points Record foundBBB grade.
- Fines and penalties 12 of 20 points Record foundPennsylvania penalties found in the sources searched.
- Contract fairness 14 of 20 points Partly default pointsThe plan could not be checked, so "simple fixed plan" got a default 2 of 4 points.
- Price 0 of 20 points Record foundA 12-month price was checked against the frozen price to compare.
- Time in business 6 of 10 points Record found
2 of this score's 62 points are default points, given because the information does not exist or could not be read. Five of six categories rest on a record we found or a search that found nothing.
This is one score built from six records, and price is one of them. It is not a measure of complaints or legal history alone. How the points are given
What the 2022 PUC settlement says
The Pennsylvania PUC approved a settlement with Green Mountain on Feb. 24, 2022 (docket M-2021-3009235). The PUC's Bureau of Investigation and Enforcement said 156 homes were switched to Green Mountain between June 2018 and September 2020 without the customer's approval, at in-person marketing sites such as retail and event locations. The order describes these as allegations. A settlement is an agreement to resolve a case.
| Term | What it says |
|---|---|
| Civil penalty | $156,000, not tax deductible |
| Refunds | The supply charges for the first two billing periods after each improper switch, plus any early termination fee another supplier charged |
| Complaint reports | Monthly reports on Pennsylvania consumer complaints for one year |
| Records | Keep enrollment tablet signatures for one year after the final order and give them to the PUC on request |
We counted this in the fines part of the score. It is more than four years old, and it is the only Pennsylvania penalty we found for Green Mountain. The score counts Pennsylvania PUC and Attorney General actions only.
What complaints say
We show only what the public records say, with their dates.
- The PUC: its 2024 report counted 9 complaints about Green Mountain, or 2.91 per 10,000 homes. The 2021 notice says the PUC's investigation began after "numerous informal complaints" from homes about switches they did not approve.
- The BBB: its Green Mountain profile (read Nov. 1, 2026) shows an A+, not accredited, 87 complaints in the last 3 years and 17 in the last 12 months. It also lists 19 customer reviews. The profile covers the whole company, not Pennsylvania alone, and the page does not break the complaints down by type.
The BBB grade comes from how a company handles its complaints, so an A+ and a long complaint list can both be true. If your bill shows a switch you did not approve, the steps are below.
What the Green Mountain contract says
We read the Pennsylvania contract summary for the month-to-month variable plan on Oct. 16, 2026.
| Term | What it says |
|---|---|
| Cancellation or early termination fee | None |
| Monthly fee | None found |
| Disputes | Arbitration before the American Arbitration Association, or small claims. The contract "does not permit class actions or a jury trial," and we found no opt-out |
Two state rules matter if you take a Green Mountain plan. You have 3 business days after the disclosure statement to cancel. If you pick its 12-month fixed plan, expect two letters before it ends, one 45 to 60 days ahead and an options notice at least 30 days ahead.
Leaving Green Mountain
Pick your next move first, since the switch takes about a billing cycle.
- 1Choose what comes next.
A fixed plan from another supplier, or your utility's default price.
- 2Start the new plan or ask your utility.
The new supplier or your utility handles the switch, which stops Green Mountain.
- 3Keep the letters.
Save the dates and the confirmation.
Green Mountain's variable plan has no cancel fee, so you can leave the day you find a better price. If you move to a fixed plan, read that plan's cancel fee first.
If you decide to leave, compare other sellers at your address before you do.

Questions, answered
Is Green Mountain Energy legit in Pennsylvania?
Yes. It holds a Pennsylvania supplier license. When we scored it on Oct. 16, 2026, it also had an A+ from the BBB. The PUC did settle a case with it in 2022 over switches made without approval. Legit does not mean cheap, though.
Is Green Mountain Energy good in Pennsylvania?
It scores 62 out of 100 (Fair) on public records. When we scored it on Oct. 16, 2026, it earned full marks for complaints and the BBB grade. Price was its lowest part on that date.
What are Green Mountain's electricity rates in PA?
In September 2026 its own variable price list showed 18.0¢ per kWh in PPL's area and 16.2¢ in PECO's. These are dated, and a variable price can change every month, so check your bill.
Does Green Mountain charge a cancellation fee in Pennsylvania?
Not on its variable plan, per the contract summary we read. The terms of its 12-month plan were not open to us, so read them before you sign one.
How do I cancel Green Mountain Energy?
Pick your next plan or your utility's default first. The new seller or your utility handles the switch, which stops Green Mountain. Its variable plan has no cancel fee. If you just signed up, you have 3 business days after the disclosure statement to cancel.
Is Green Mountain cheap? Will it cut my electric bill?
No, not on the prices we read. Its variable price ran about 38% above the price to compare in September 2026.
Is Green Mountain on PA Power Switch?
Not when we looked on Oct. 24, 2026. It sells through its own site, which loads its offers by script, so check the price on the company's page and on your bill.
Is Green Mountain Energy owned by NRG?
Yes. NRG Energy agreed in 2010 to buy it, and NRG's annual report lists Green Mountain Energy as one of its brands. It still sells under its own name and holds its own PUC licence.
Is Green Mountain Energy the same company in Texas?
The name is the same and so is the owner. Rules and prices differ by state. See our Texas review.
Why is Green Mountain on my bill?
Someone may have agreed to a Green Mountain plan, often at an in-person sign-up. If no one did, dispute the switch with your utility inside two billing periods.
