Your electricity in zip code 78750 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.
Cedar Park's 78750 zip code sits in Williamson County — one of the fastest-growing counties in Texas — and benefits from a fully deregulated electricity market served by Oncor Electric Delivery. With a median household income of $93,439 and a city population of 82,220, Cedar Park attracts serious competition among retail electric providers. In March 2026, residents in 78750 have access to 364 plans from 49 competing providers, with rates ranging from as low as 7.9¢/kWh all the way up to the market average of 13.0¢/kWh. That's a meaningful spread — and it means shopping carefully can save Cedar Park households hundreds of dollars annually compared to simply staying on a default or expired plan.
The most competitive rate currently available in 78750 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 — meaning savvy shoppers who find the best rate could save roughly 5.1 cents per kilowatt-hour compared to the market average. For a household using 1,200 kWh per month, that translates to roughly $61 in monthly savings, or more than $730 per year. Pricing in this area is influenced by Oncor's regulated delivery charges, wholesale energy costs on the ERCOT grid, and the fierce provider competition that keeps retail margins lean.
In 78750, short-term plans (1–6 months) are actually averaging the most competitive rates right now at 11.1¢/kWh — notably below the medium-term average of 13.0¢/kWh and the long-term average of 13.7¢/kWh for plans 19 months or longer. This is somewhat unusual and may reflect current wholesale market conditions on ERCOT. Short-term plans make sense if you're renting, planning to move, or want flexibility to re-shop when rates shift. Medium-term plans (7–18 months) offer a balance of stability and competitive pricing, ideal for most Cedar Park homeowners. Long-term plans provide rate certainty through multiple Texas summers — worth considering if you're risk-averse about potential price spikes — though right now they carry a premium over shorter contracts.
With 49 retail electric providers competing for customers in the Oncor service area covering 78750, this is one of the most competitive electricity markets in Texas. Providers actively vying for Cedar Park customers include Chariot Energy, Reliant Energy, Direct Energy, Rhythm Energy, Cirro Energy, Shell Energy, 4Change Energy, TXU, Frontier Utilities, Good Charlie, and many others. This level of competition means providers frequently offer promotional rates, bill credits, and renewable energy options — including 82 green or renewable-energy plans — to attract and retain customers. Consumers hold significant leverage here.
Regardless of which retail provider you choose, your physical electricity delivery in 78750 is handled exclusively by Oncor Electric Delivery (ONCOR), reachable at 1-888-313-4747 or oncor.com. Oncor maintains the poles, wires, and meters in this area. Critically, Oncor's delivery charges are regulated by the Public Utility Commission of Texas and are identical no matter which retail provider you select — so comparing providers is purely about the energy supply portion of your bill. Switching providers is free, causes zero service interruption, and your new rate takes effect on your next scheduled meter read date.
Compared to nearby Cedar Park zip codes — including 78613, 78630, 78641, and 78726 — the 78750 zip code operates within the same Oncor service territory and sees broadly similar rate dynamics. Neighboring markets like Argyle and Balch Springs also average around 9.9¢/kWh with 27 providers, highlighting how 78750's access to 49 providers and rates starting at 7.9¢/kWh represents a particularly strong competitive environment. Seasonally, Cedar Park electricity demand peaks sharply in July and August when temperatures regularly exceed 100°F — locking in a fixed rate before summer is a widely recommended strategy for households in this area.

Lock in a 12- or 24-month fixed-rate plan before May each year. Cedar Park's summer cooling season drives peak demand pricing from June through September — signing early can save you 1–2 cents per kWh compared to mid-summer rates.
If your Cedar Park home has a smart thermostat, consider a time-of-use or free-nights plan. Shifting major appliance use — laundry, dishwashers, EV charging — to after 9 p.m. can significantly reduce your monthly bill during peak summer months.
Check whether your Cedar Park address falls under Oncor or Austin Energy service before comparing plans. Residents in zip codes 78726 and 78750 near the Austin border should verify their TDSP, as Austin Energy customers cannot access the deregulated market.
Cedar Park's intense summer heat means your HVAC system likely accounts for 50–60% of your annual electricity bill. Schedule a pre-summer tune-up and seal attic air leaks to reduce consumption regardless of which REP you choose.
After any severe weather event — including the increasingly common Central Texas hailstorms — compare electricity plans again. Insurers aren't the only ones adjusting; REPs often release competitive promotional rates in the months following grid stress events.
As of March 2026, the most competitive rate in 78750 is 7.9¢/kWh, available through the GridPlus 12 plan from Chariot Energy. That's well below the current market average of 13.0¢/kWh across all 364 available plans in this zip code.

Current ERCOT wholesale market conditions are making short-term plans (averaging 11.1¢/kWh) more competitive than long-term contracts (averaging 13.7¢/kWh) in March 2026. This can shift — locking in a medium-term plan before summer demand peaks is often a smart hedge.
