League City is the largest city in Galveston County and one of the fastest-growing communities in the Clear Lake corridor. Home to NASA's Johnson Space Center workers, aerospace industry employees, and Houston commuters, it has a well-educated, suburban demographic and a housing stock that trends toward mid-to-large single-family homes. Every League City address is within CenterPoint Energy's deregulated service area.
The short answer
League City ZIP codes 77573 and 77574 are CenterPoint Energy territory — fully deregulated. Fixed-rate plans as of May 2026 typically advertise 9.5–13.5¢/kWh at 1,000 kWh. League City's suburban homes typically use 1,200–1,800 kWh in summer, meaning the real bill exceeds what the advertised rate implies for most households.

CenterPoint Energy in League City — Galveston and Harris Counties
League City spans Galveston County (the larger portion) and Harris County (the northern section adjacent to Friendswood and Pearland). Both sides of the city boundary are within CenterPoint Energy's service territory. CenterPoint's TDSP charges — a fixed monthly customer fee plus a per-kWh distribution charge — are identical across both county portions of the city and are regulated by the PUCT.
At 1,000 kWh, CenterPoint's TDSP charges typically add $13–$18 to a League City bill. At 1,500 kWh in summer, the delivery component rises to $18–$25. These amounts appear on your bill regardless of your REP and cannot be reduced by switching providers.
League City's Housing Character and Typical Usage
League City's housing stock was built primarily in three waves: established neighborhoods from the 1980s–1990s in the central and east sections (primarily 77573), followed by a major growth wave in the 2000s across both ZIPs as Clear Lake commuters pushed south, and ongoing new construction in the western portions (77574) as the city continues expanding. Homes range from townhomes near Clear Creek to 3,500 sq ft lakefront properties.
| ZIP | Area | Typical Summer Usage |
|---|---|---|
| 77573 | Central / East League City, Clear Creek corridor | 1,100–1,600 kWh |
| 77574 | West League City, newer development | 1,300–1,900 kWh |
A Texas example
Kevin, a contractor at NASA/JSC, lives in a 2,400 sq ft home in League City (77573). August usage: 1,580 kWh. Plan advertised at 10.2¢/kWh. Expected energy charge at 1,000 kWh: ~$102. Actual August energy charge: $163.32 at the interpolated rate of 10.34¢/kWh. Adding CenterPoint TDSP ($22), taxes ($10), and a $9.95 base charge, his full August bill was $205.27. The advertised rate implied a ~$118 all-in bill. The real bill was $87 higher.
Coastal Considerations — Humidity and Storm Risk
League City's proximity to Galveston Bay means higher ambient humidity than inland DFW suburbs. High humidity increases effective temperature — humid 95°F days feel hotter and drive AC systems to run longer to achieve the same indoor comfort level. League City summer usage patterns reflect this: homes in 77574 close to Clear Lake and the bay often run 10–15% more electricity than equivalent homes in drier Dallas suburbs would.
Hurricane season (June through November) also presents a specific risk: tropical systems can knock out power for days and sometimes weeks in the worst cases. A fixed-rate electricity plan provides no protection against extended outages — that is a generator or battery storage question — but it does protect against the price spikes that can occur when restoration demand strains the grid in a storm's aftermath and providers adjust variable rates upward.
Watch out
League City sits in a hurricane-prone coastal zone. If you are on a variable-rate electricity plan during and after a major storm event, your provider can legally increase your rate month-to-month with 14 days' notice. Fixed-rate plans are contractually locked for the term — your rate cannot change even if ERCOT wholesale prices spike during or after a storm. If you are currently on a variable plan in League City, switching to a fixed rate before hurricane season ends (November 30) is a meaningful risk-management step.
Smart move
League City homes with high coastal humidity benefit disproportionately from properly sized HVAC equipment. An oversized AC unit cools the air quickly but does not run long enough to remove humidity — leaving the home feeling clammy and often causing residents to lower the thermostat further, increasing electricity use. If your home feels humid even when the AC is running, have an HVAC technician check for proper sizing. Correcting an oversized system can reduce electricity use 15–25% with no change to the thermostat setting.
Key Takeaways
League City ZIP codes 77573 and 77574 are CenterPoint territory — TDU charges are fixed. Coastal humidity drives slightly above-average summer usage relative to equivalent homes in drier inland cities. Fixed-rate plans provide meaningful storm-season price protection in addition to their standard cost predictability. Compare plans at your actual summer usage for an accurate bill estimate.
