Pay an Allegheny Energy bill, now part of the FirstEnergy company, online by visiting FirstEnergyCorp.com and logging in to your customer account and navigating to the Pay My Bill section, as of 2015. This allows you to make a one-time payment or establish recurring deductions for the bill total using a credit card, debit card or bank account.
You must have an account with FirstEnergy in order to pay your bill online, which you can obtain for free by providing your service account number during the account registration process. After you log in, go to the My Account section and choose the Pay My Bill option to immediately access the payments page. It is also possible to view an electronic version of your bill through the account to understand the current and previous charges as well as ensure the accuracy of the balance due.
Once on the payments page, you must choose either the one-time payment option or set up the recurring charge feature. Single payments allow you to pay the current balance or a custom amount at any time by providing the company with your credit or debit card's number, expiration date, security code and billing ZIP code. One-time payments with a checking account require the routing number and account number from your bank. The process for setting up recurring payments also requires you to choose one of the payment options and provide the necessary details, along with setting your preferences for payment amounts.
