Oncor, an investor-owned transmission and distribution utility, is certified to provide electric service to deregulated areas across the state. In the Austin area, Oncor serves customers in Round Rock, Taylor and Elgin in Williamson County, Pflugerville in Travis County, as well as parts of north Austin. Customers in deregulated areas choose among completive retail electric providers. For businesses, shopping for electricity can be a negotiated purchase process, similar to the purchase of a large quantity of computers or wholesale materials for manufacturing or business operations. The Power to Choose website of the Public Utility Commission of Texas allows electric customers to compare providers and plan options.
Austin customers in the Oncor territory may shop for a third-party electricity provider.
