Convenient Ways to Pay Your Alliant Energy Bill

Having options for paying your monthly utility bill easily and quickly is important. Alliant Energy offers their customers various payment methods to choose from based on convenience and preference. In this article, I’ll explain the different ways you can pay your Alliant Energy bill and highlight the advantages of each method.

Pay Online

The most popular way to pay an Alliant Energy bill is online through their eBill program. With eBill, you can view your current charges, see payment history, and make secure online payments. Payments post instantly when made through eBill, so it’s a great option if your bill is due soon.

To start using eBill visit AlliantEnergy.com and either register for a new account or sign into your existing account. You’ll need your account number and PIN handy when you register. Once your account is created you can log in anytime to view and pay your bill.

I personally like using eBill because it’s simple and fast. I have the website bookmarked on my laptop and phone for easy access. The autopay feature also lets you setup recurring payments from a bank account or credit card, so your bill gets paid automatically each month.

Pay By Phone

Alliant Energy offers a pay-by-phone system that’s available 24/7 for your convenience. To use it, dial 1-800-255-4268 and select the “Pay by Phone” option. The automated system will guide you through the payment process.

You’ll need to enter your 10-digit account number and 4-digit PIN when prompted. Keep your latest bill handy because your PIN is usually printed on it. The system accepts payments from debit cards, credit cards, and checking or savings accounts.

The phone payment process only takes about 5 minutes. I like using it for those months when I forget to pay online. The automated system is quick and redirects you to a live agent if you need additional help.

Pay by Mail

Sending a check or money order through the mail is a traditional way to pay your Alliant Energy bill. To pay by mail, write your 10-digit account number on your payment and send to:

Alliant EnergyPO Box 3062Cedar Rapids, IA 52406-3062

Be sure to mail your payment at least 5-7 days before the due date listed on your bill This gives sufficient time for Alliant Energy to receive and process the payment, I recommend paying by mail only as a backup option in case you miss the online or phone payment deadlines,

Pay in Person

Alliant Energy has local customer service offices where you can pay your bill in person with cash, check, or money order. When you arrive, let the representative know you are there to make a payment. They will look up your account and process the payment for you.

Paying at a customer service office gives you the chance to ask questions and get personalized support. However, be aware that wait times can be long during peak billing periods as the staff assists other customers.

Authorize a Payment Location

Another in-person option is to authorize a payment location like Walmart or CheckFreePay to accept payments on Alliant Energy’s behalf. To use this method, visit or call your local authorized payment location and provide your 10-digit account number. The staff can then collect a payment and have it applied directly to your Alliant Energy account.

The benefit of paying at an authorized third-party location is convenience, as you can combine your utility payment with other shopping errands. Just confirm the payment center accepts Alliant Energy bills before going.

Pay Using Alliant Energy Rewards

If you participate in Alliant Energy’s Rewards program, you can use your reward points to make payments. Access your Rewards through the online account portal or mobile app and select the option to redeem points for a bill credit.

10,000 points are equivalent to a $10 bill credit. Redeeming points to pay your bill is an easy way to put your rewards earnings to good use. It helps lower or eliminate your monthly payment.

Enroll in Average Monthly Payment

Alliant Energy offers an Average Monthly Payment plan that lets you pay a fixed amount each month based on your projected annual usage. To enroll, your account must be up-to-date without past due balances. Once enrolled, your monthly budget amount gets recalculated twice a year.

The main benefit of this plan is predictable payments and avoiding large fluctuations from month to month. I recommend Average Monthly Payment if you’re on a tight budget and prefer consistency. Keep in mind you may need to pay more or receive credits at the end of the year to settle any differences from your actual usage.

Sign up for Auto Pay

For ultimate convenience, enroll in Auto Pay to have your Alliant Energy bill paid automatically each month. Payments can be drafted from your checking or savings account, or charged to a credit or debit card.

To start Auto Pay, login to your online account and complete the enrollment form. The payment will be processed on the due date each month so you don’t need to remember to pay manually. Auto Pay gives peace of mind knowing your electric and gas services won’t be disrupted due to a late payment.

Use a Third-Party Payment Service

You can also pay your Alliant Energy bill through third-party services like online banking bill pay offered by your bank or fintech apps like PayPal. These services let you set up one-time or recurring payments to Alliant Energy.

The catch is that payments through third parties take 1-2 weeks to process compared to instant processing with Alliant Energy’s online and phone payment methods. Make sure to schedule third-party payments well in advance of your due date to avoid late fees.

Decide What Works for You

At the end of the day, choosing how to pay your Alliant Energy bill comes down to personal preference and convenience. With online, phone, mail, in-person, and third-party options, you can easily select the method that fits your needs each month.

I recommend setting up Auto Pay or recurring online payments to ensure your bill always gets paid on time. But having alternatives like the pay-by-phone system or authorized payment locations gives you flexibility as needed. Take advantage of the many payment choices Alliant Energy offers their customers.
