While you can choose your electricity provider in a deregulated market, your utility company is determined by your address and cannot be changed. Utilities deliver electricity, maintain power lines, and restore service during power outages. The utility company for Round Rock is Oncor Electric Delivery. In the event of a power outage or electrical emergency, call your utility company, not your provider. Here’s how to contact Oncor:
All utility companies charge a transmission and distribution utility (TDU) fee for delivering electricity. This includes a base monthly charge and a usage charge per kWh. Oncor Electric Delivery charges $4.23/month and 5.6032 cents/kWh.

Already live in Round Rock, but want to change your energy plan? With Choose Texas Power, you can browse rates from different Round Rock electricity providers and switch energy companies quickly and easily. But before you do, check your current plan’s contract. If it’s a fixed-rate plan, your provider will likely charge an ETF if you switch before the contract is up.
Today, Frontier Utilities has the cheapest Round Rock electricity rates on our marketplace. However, rates change regularly. At other times, you might find affordable rates from providers like 4Change Energy, Express Energy, or APG&E.

One easy way to reduce your electric bill in Round Rock is to switch to a plan with a cheaper rate. You can also try different energy-conserving tactics, such as unplugging unused appliances, weatherstripping windows and doors, replacing your HVAC filters every few months, and running your washing machine with cold water.
Everyone’s energy needs are different, so the “best” provider will depend on what’s important to you. For example, if you prefer green energy plans, you might consider Gexa Energy or Green Mountain Energy. On the other hand, if you have subpar credit and don’t want to pay a deposit, then Payless Power (which sells prepaid plans) might be a better fit.
Let us put the power in your hands with a new electricity plan.
