Tips & Tricks for Canceling Green Mountain Energy
- Call Con Edison (ConEd) directly with the number on your Green Mountain Energy bill to request cancellation; ConEd can remove you from Green Mountain and revert you back to their supply service.
- Inform ConEd you want to get off your ESCO (Green Mountain Energy) and they will handle the unenrollment process, which can take about 1-2 months.
- After calling ConEd, send an email to Green Mountain Energy at nycustomercare@greenmountain.com with a notice of cancellation, including your account number and any relevant details; some users include a signed and dated cancellation form.
- Keep any confirmation codes or documentation you receive from either ConEd or Green Mountain Energy as proof of cancellation.
- Avoid signing contracts or agreements with Green Mountain Energy in person (e.g., on the street), as this can lead to hidden fees or difficulties cancelling.
- Cancel before the plan start date if possible, because once the plan starts, cancellation fees can range from $150 to $295.
- If solicited again by Green Mountain Energy representatives, respond with "already use you!" to avoid further contact attempts.
- Do not rely solely on calling Green Mountain Energy for cancellation, as some users report better success cancelling through ConEd.
- Be aware that the cancellation process may take some time, so monitor your account and bills closely to ensure the cancellation is completed and that no unexpected charges appear.
- If problems arise, escalate by contacting ConEd's customer service supervisors, or referencing New York State regulations that allow rescinding a service agreement within three days of signing without penalty.

Frequently Asked Questions
Green Mountain Energy allows customers to rescind their agreement without penalty within three federal business days after enrollment authorization and receipt of contract documents. After this period, cancellation is not guaranteed without penalty and early termination fees may apply if switching providers. No cancellation fee applies if you move, but other fees related to payments and disconnection notices may apply.
To cancel your subscription with Green Mountain Energy, you generally need to have access to your online account, which requires your password. If you prefer, you can also call their customer service at 1-888-835-4672 to cancel without necessarily logging in. If you need to reset your password to access your account, you can do so at this URL: https://myaccount.greenmountainenergy.com/resetpassword. This way, you can either cancel online or by phone with your account details.

- Confusing and deceptive billing practices with unclear explanations and rising deferred balances.
- Poor customer service experiences including unhelpful support and conflicting information.
- Rate increases on fixed-rate plans without proper notice or transparency.
- Higher-than-advertised energy rates compared to competitors.

Green Mountain Energy may seem to have tricky timing around cancellation, as their cancellation fee applies until 14 days before your first meter read after contract expiration, preventing fee-free early cancellation before that notice period. While you can typically cancel at any time, cancelling before receiving two renewal notices or during the variable price portion means no early termination fee, but you might forfeit some rewards and must pay any unpaid balances. So, the main landmine is that you are financially locked in until close to contract end, and early cancellation might come with unexpected costs depending on timing.
Before cancelling your Green Mountain Energy subscription, know that you may lose access to renewable energy benefits that support cleaner energy sources. There could be a cancellation fee associated with terminating your membership early. Also, cancelling may affect your billing cycle and any ongoing promotions or discounts you were receiving. It's important to review your contract terms and contact customer service for specific details related to your subscription.

- Understand if you are still within the rescission period (typically 3 days after contract signing) for immediate cancellation without penalty
