Your electricity in zip code 78682 is delivered by Oncor Electric Delivery. Since this area is deregulated, you can choose your retail electricity provider while Oncor Electric Delivery maintains the power lines and handles outage restoration.
Round Rock's 78682 zip code sits in Williamson County — one of Texas's fastest-growing counties — and benefits from a fully deregulated electricity market served by Oncor Electric Delivery. With a city population of over 133,000 and a median household income of $82,842, this is a high-demand service area that attracts serious competition among retail electric providers. In March 2026, residents in 78682 have access to 364 electricity plans from 49 competing providers, with rates starting as low as 7.9¢/kWh. That level of competition is genuinely good news for consumers — it means providers are consistently undercutting each other to earn your business, and switching has never been easier or more rewarding.
The most competitive rate available in 78682 right now is 7.9¢/kWh, offered through the GridPlus 12 plan from Chariot Energy. The average rate across all 364 available plans sits at 13.0¢/kWh, which means savvy shoppers who take the time to compare can save significantly compared to defaulting to a mid-market plan. The spread between the best and average rate — over 5 cents per kilowatt-hour — is meaningful: on a 1,500 kWh summer month, that difference translates to roughly $75 in savings. With 82 green/renewable plans also in the mix, environmentally conscious households have strong options without sacrificing price competitiveness.
In 78682, contract length has a notable impact on pricing. Short-term plans (1–6 months) currently average 11.1¢/kWh — the most affordable average tier, making them attractive for renters, newcomers, or anyone who wants flexibility while watching the market. Medium-term plans (7–18 months) average 13.0¢/kWh, which mirrors the overall market average and offers a balance of stability and reasonable pricing. Long-term plans (19+ months) average 13.7¢/kWh — the highest average tier, though they can provide peace of mind against rate volatility heading into summer. For most Round Rock homeowners planning to stay put, a 12-month fixed-rate plan often hits the sweet spot between price and protection.
With 49 retail electric providers actively competing in this Oncor zone, 78682 is a high-competition market by any measure. Providers include well-known names like Reliant Energy, TXU, Direct Energy, and Shell Energy, alongside competitive challengers like Chariot Energy, Rhythm Energy, 4Change Energy, Cirro Energy, and Frontier Utilities. Newer entrants like Good Charlie and Freepoint Energy are also competing aggressively on price and perks. This breadth of competition keeps promotional offers frequent and pricing sharp — consumers who compare plans every 12 months are routinely rewarded.
Regardless of which retail provider you choose, your electricity will be physically delivered through Oncor Electric Delivery's infrastructure. Oncor is the regulated Transmission and Distribution Service Provider (TDSP) for this area, and its delivery charges are set by the Public Utility Commission of Texas — meaning they're identical no matter which REP you select. Oncor handles outages, meter reads, and line maintenance. You can reach them at 1-888-313-4747 or at oncor.com. Switching providers in 78682 is free, causes no service interruption, and takes effect on your next meter read date — you simply provide your ESIID number to your new provider.

Lock in a fixed-rate plan before Memorial Day weekend. Round Rock's July and August heat routinely pushes AC systems into overdrive, and variable-rate plans can see sharp price increases during peak ERCOT demand periods — a fixed rate gives you a predictable bill all summer.
Set your thermostat to 78°F when home and 85°F when away during summer. With highs regularly hitting 98–105°F in Round Rock from June through September, each degree of setpoint adjustment can reduce your cooling costs by approximately 3% per month.
Audit your plan at least once a year — ideally every October. Contract terms that were competitive 12 months ago may no longer reflect the best available rates. Use Choice Energy Network to compare current Round Rock offers before your contract auto-renews.
If you work from home or have a Kalahari water park-level household with kids home all day, investigate free nights or time-of-use plans. Shifting dishwasher, laundry, and EV charging to off-peak hours can meaningfully cut your monthly Oncor delivery and energy charges.
After Winter Storm Uri, consider adding a whole-home surge protector and reviewing whether your REP plan includes any bill assistance or payment protection features. Several Round Rock-area REPs offer Winter Suspension protection that limits disconnect risk during declared weather emergencies.
