You probably already know that Texas has a deregulated energy market, meaning customers who use retail electricity in Austin are not required to sign a contract with Austin energy providers. If a consumer has a smart meter, they can choose a Smart Prepaid Electric plan to pay as they go.
What is the mechanism behind it? Your chosen power company in Austin can utilize the smart meter number to create a new account remotely. Then, the Smart Prepaid Electric plan requires the consumer to pay for energy upfront. The account balance changes daily as the consumer uses energy. The user can always top it up by paying online, over the phone, through the mail, or at a payment center.
