Deregulation restructured the way the energy industry functions. Think of the energy industry in three steps: sales, transmission and delivery. Previously, all three steps were carried out by one single Irving wires company (or utility service). While the primary utility company still carries out the transmission of energy and delivery to residences, the responsibility for selling the energy plans has been opened up to competition among supplier companies. These suppliers attempt to win business from Irving residents by offering cheaper rates and better plan terms.
Electric bills for customers in the Houston area can more than double in summer months, mainly because air conditioning. Not coincidentally, electric rates also rise in the summer months because of this increase in demand. The most dramatic rate increases occur in month-to-month plans, but electric rates do increase across the board for all fixed-rate contract lengths.

The nature and state of market reform of the electricity market often determines whether electric companies are able to be involved in just some of these processes without having to own the entire infrastructure, or citizens choose which components of infrastructure to patronise. In countries where electricity provision is deregulated, end-users of electricity may opt for more costly green electricity.
Around 85% of Texas residents must choose an electricity provider. Utility companies transmit and distribute electricity to customers. But that electricity doesn’t come from a utility—it comes from companies known as Retail Electric Providers. These providers offer competitive plans based on electricity pricing, term length, renewable sourcing and more.
