Cedar Park, Texas (zip code 78613) sits in Williamson County — one of the fastest-growing counties in the nation — and benefits from a fully deregulated electricity market served by Oncor Electric Delivery. As of March 2026, Cedar Park residents have access to 364 electricity plans from 49 competing retail providers, making this one of the most competitive energy markets in Texas. With a median household income of $93,439 and a city population of over 82,000, Cedar Park attracts aggressive provider pricing and frequent promotional offers. The average rate across all plans currently sits at 13.0¢/kWh, but savvy shoppers can find rates as competitive as 7.9¢/kWh — a difference that can translate to hundreds of dollars in annual savings for the typical household.
The March 2026 electricity market in Cedar Park 78613 offers a wide range of pricing options. The most competitive rate available is 7.9¢/kWh on the GridPlus 12 plan from Chariot Energy, while the average rate across all 364 plans is 13.0¢/kWh — meaning there's meaningful savings potential for residents willing to shop. The spread between the best and average rates reflects the diversity of plan structures available, from bare-bones fixed-rate contracts to premium renewable and smart-home-integrated offerings. Seasonal demand in the Austin metro corridor typically pushes rates upward heading into summer, making March an ideal time to lock in a competitive fixed rate before spring and summer pricing pressures take hold.
Contract length has a significant impact on what you'll pay in 78613. Short-term plans (1–6 months) currently average 11.1¢/kWh — notably lower than medium-term (7–18 months) at 13.0¢/kWh and long-term (19+ months) at 13.7¢/kWh. This inverted pricing structure suggests that short-term plans may offer the best immediate value, particularly for renters, homeowners between moves, or those who want flexibility to re-shop before summer. However, locking in a medium-term plan at a competitive fixed rate provides price certainty through peak summer billing months — a real advantage when July and August bills can spike dramatically. Long-term contracts above 19 months carry the highest average cost right now and are best suited only if you find a standout fixed rate well below the average.
With 49 providers actively competing in the Oncor service area covering 78613, Cedar Park residents have exceptional market leverage. Major providers serving this zip include Reliant Energy, Direct Energy, Chariot Energy, Rhythm Energy, TXU, Shell Energy, 4Change Energy, Cirro Energy, and Frontier Utilities, among dozens more. This level of competition drives providers to offer promotional pricing, bill credits, and renewable energy options — including 82 green/renewable plans currently available. Don't default to a well-known name alone; smaller providers like Good Charlie and Freepoint Energy often carry highly competitive rates with strong customer service reputations.

Oncor maintains the poles, wires, and meters in Cedar Park and can be reached at 1-888-313-4747 or oncor.com for outage reporting and service issues. Critically, Oncor's delivery charges are state-regulated and identical no matter which provider you select — so switching providers never affects your delivery service or creates any interruption.

The Austin-area growth corridor creates sustained electricity demand, which makes early-spring rate shopping in Cedar Park especially strategic before summer peak pricing arrives.

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.
