Where to pay your Green Mountain Energy bill
Green Mountain Energy offers three main ways to pay your bill: online through their website, by phone, or by mail. The fastest and most convenient method is online payment through your account on greenmountainenergy.com. You can set up a one-time payment or enroll in autopay, which charges your bank account or credit card on your due date each month.
If you prefer to pay by phone, call Green Mountain Energy's customer service line at 1-800-624-6081. A representative can process your payment over the phone using a debit card, credit card, or bank account. This method takes a few minutes and your payment posts immediately.
For mail payments, send a check or money order to the address printed on your bill. Include your account number on the check and mail it to the address listed in the "Payment" section of your statement. Mail payments typically take 7 to 10 business days to post to your account, so send them early if your due date is approaching.

Setting up autopay to avoid missed payments
Autopay is the easiest way to ensure your bill is paid on time every month. Log into your Green Mountain Energy account online, go to the payment settings, and select "Enroll in Autopay." You can choose to pay the full bill amount or a fixed amount each month. Green Mountain Energy will charge your chosen payment method on your due date automatically.
If you enroll in autopay by phone, call 1-800-624-6081 and provide your payment method details to a representative. They will set up the recurring charge and confirm the date it will process. You can change or cancel autopay at any time through your online account or by calling customer service.
Autopay is especially useful if you have a variable bill amount each month, since you can adjust the payment method or amount before each billing cycle. Some customers choose a fixed autopay amount and pay any remaining balance manually when the bill arrives, which gives them flexibility while still meeting the due date.
What happens if you miss a payment
If your payment does not arrive by the due date shown on your bill, Green Mountain Energy will typically send you a late notice within a few days. This notice gives you a grace period—usually 10 to 15 days—to make the payment before the company takes further action. During this time, you will not face a disconnection if you pay promptly.
If you do not pay within the grace period, Green Mountain Energy may disconnect your service. Before disconnection, the company must send you a final notice with at least 5 business days' warning. Once service is disconnected, you will owe a reconnection fee in addition to your unpaid balance. The reconnection fee varies but is typically $50 to $100.
If you know you will miss a payment, contact Green Mountain Energy immediately at 1-800-624-6081. Customer service representatives can sometimes arrange a payment plan or extension, especially if this is your first late payment. Explaining your situation early gives you more options than waiting until after disconnection.
Understanding your bill due date and billing cycle
Your bill due date appears clearly at the top of your statement. Green Mountain Energy typically bills monthly, and your due date is usually 20 to 25 days after the bill is issued. The billing cycle covers your energy use during the previous month, so the charges on your current bill reflect the electricity you consumed last month, not this month.
Your billing date and due date stay the same each month unless you request a change. If you want to shift your due date to align with your payday or another date that works better for your budget, call customer service and ask to change your billing cycle. This change usually takes effect within one or two billing periods.
The due date is the last day you can pay without triggering a late fee. If your due date falls on a weekend or holiday, Green Mountain Energy typically accepts payments through the next business day. However, do not rely on this—pay a day or two early to be safe, especially if you are mailing a check.
Payment methods and fees
Green Mountain Energy accepts debit cards, credit cards, and bank account transfers for online and phone payments. There is no fee for paying by debit card or bank transfer. Credit card payments may incur a processing fee of 2 to 3 percent, depending on the card type and payment processor. Check the fee amount before you confirm a credit card payment online.
Mail payments by check or money order have no processing fee, but they take longer to post. If you use a third-party bill payment service through your bank, confirm that the payment is sent to the correct Green Mountain Energy address and arrives before your due date. Some bank bill pay systems can delay payments by several days.
If you pay in person at a Green Mountain Energy office or authorized payment location, ask about any fees before you pay. Not all Green Mountain Energy service areas have walk-in payment offices, so check the company website or call customer service to find a location near you.
Troubleshooting payment problems
If you made a payment online or by phone but do not see it reflected on your account within 24 hours, log into your account and check the payment status. Online payments usually post within a few hours; phone payments post immediately. If the payment shows as pending, wait until the next business day before contacting customer service.
If a payment was rejected—for example, because your card was declined or your bank account information was incorrect—Green Mountain Energy will send you a notice. The notice explains why the payment failed and gives you instructions to resubmit. Resubmit your payment as soon as possible to avoid late fees or service disconnection.
If you believe a payment was charged twice or if you have questions about a charge on your bill, contact customer service at 1-800-624-6081. Have your account number and recent payment records ready. Representatives can review your payment history and correct any errors, though this may take a few business days.
Frequently Asked Questions
Can I pay my Green Mountain Energy bill with a prepaid card?
Yes, you can use a prepaid card online or by phone as long as it has a Visa, Mastercard, or American Express logo and is registered with your name and address. Some prepaid cards charge fees for bill payments, so check your card's terms before using it. If the payment is declined, contact your prepaid card issuer to confirm the card is active and has sufficient funds.
What is the difference between my billing date and my due date?
Your billing date is when Green Mountain Energy generates your bill and sends it to you. Your due date is when payment must arrive to avoid late fees, typically 20 to 25 days after the billing date. The bill itself covers energy use from the previous month, not the current month.
Can I set up autopay for only part of my bill?
Yes. You can set autopay to charge a fixed amount each month and pay any remaining balance manually when the bill arrives. This works well if your bill varies significantly month to month. Adjust your fixed autopay amount through your online account or by calling customer service.
How long does it take for a mailed check to post?
Mailed checks typically take 7 to 10 business days to arrive and post to your account. Mail your payment at least 10 to 12 days before your due date to ensure it arrives on time. If your due date is fewer than 10 days away, use online or phone payment instead.
What happens if I pay after the due date but before disconnection?
If you pay during the grace period after your due date but before disconnection, you will avoid service interruption. However, you may still owe a late fee depending on your service area and Green Mountain Energy's policies. Contact customer service to confirm whether a late fee will be applied to your account.
