Last updated: October 18, 2026 · 7 min read
Spring is an unincorporated community in north Harris County and south Montgomery County — one of the most densely populated unincorporated areas in the United States. Without city limits, Spring's identity is defined by its major thoroughfares (Spring-Cypress Road, FM 2920, Kuykendahl Road) and its master-planned communities: Gleannloch Farms, Klein, Champions, and Northampton. Most Spring addresses fall within CenterPoint Energy's deregulated service territory, giving residents full access to the competitive electricity market.
The short answer
Most Spring ZIP codes (77373, 77379, 77386, 77388, 77389) are CenterPoint Energy territory — fully deregulated. Some ZIP codes near the Montgomery County line may include Sam Houston Electric Cooperative addresses. Fixed-rate plans as of May 2026 advertise 9.5–13.5¢/kWh at 1,000 kWh. Typical Spring summer usage runs 1,200–1,700 kWh. Enter your ZIP to confirm your TDU and see ranked plan options.
CenterPoint in Spring — and the Cooperative Boundary
CenterPoint Energy serves the majority of Spring in north Harris County. As Spring's residential development has extended northward into Montgomery County, some newer addresses fall within the service territory of Sam Houston Electric Cooperative (Sam Houston Electric Co-op), a member-owned cooperative that is not part of the deregulated market. Co-op customers pay rates set by the cooperative board and cannot shop for competitive plans.
The easiest way to confirm your TDU: enter your Spring ZIP code in the search tool or at powertochoose.org. If competitive plans appear, you are in CenterPoint's service area and can shop. If no plans appear, call Sam Houston Electric Cooperative (1-800-482-1765) to discuss your rate options.
Spring ZIP Codes — What Each Area Covers
| ZIP | Area | Typical Summer Usage | TDU |
|---|---|---|---|
| 77373 | Central Spring, older neighborhoods | 1,000–1,500 kWh | CenterPoint |
| 77379 | Klein area, Champions | 1,100–1,600 kWh | CenterPoint |
| 77386 | Spring-Woodlands border, Gleannloch | 1,200–1,800 kWh | CenterPoint |
| 77388 | Northeast Spring | 1,000–1,500 kWh | CenterPoint |
| 77389 | Creekside Park / Woodlands border | 1,300–2,000 kWh | CenterPoint |
A Texas example
Diane in Gleannloch Farms (77386) has a 2,500 sq ft home with three bedrooms and a pool. August usage: 1,720 kWh. Plan advertised at 10.0¢/kWh. Expected energy bill at 1,000 kWh: $100. Actual August bill: $208.54. At 1,720 kWh, the plan's interpolated rate was 9.64¢/kWh, energy charge $165.81. CenterPoint TDSP added $22, taxes $11, and the $9.95 base charge completed the bill. Diane's plan choice looked different when she saw the summer bill — a plan with a higher advertised rate but a lower rate at 2,000 kWh would have been cheaper at her actual usage.
Gleannloch Farms, Champions, and Klein — What Makes Spring Usage Varied
Spring's residential character spans multiple decades of suburban development. The Champions area (77379) and central Spring (77373) have significant 1970s–1990s housing, with homes typically 1,500–2,200 sq ft. Gleannloch Farms and the Woodlands-border communities (77386, 77389) are newer and larger, with many 2,500–4,000 sq ft homes built in the 2000s and 2010s.
This spread in home size and construction vintage means there is no single "typical" Spring usage — a 1,400 sq ft 1980s ranch home in Klein might use 1,100 kWh in August while a 3,500 sq ft Gleannloch home with a pool uses 2,100 kWh. The right plan for each is likely different. Comparing at the 1,000 kWh benchmark treats these two households identically when they need to be compared at their respective usage levels.
The math
Spring home using 1,450 kWh in August. Plan A: 10.3¢ at 1,000 kWh, 9.5¢ at 2,000 kWh — interpolated rate: 9.83¢, energy charge $142.54. Plan B: 9.9¢ flat at 1,000 and 2,000 kWh — energy charge $143.55. Plan A saves $1.01/month at this usage level despite advertising a higher rate. Multiply that across 5 summer months: $5.05 saved. Small? Yes — but the ranking would be much more pronounced at 2,000 kWh, where Plan A's discount versus Plan B grows to $8/month. Knowing where the savings live in your usage range is what makes accurate comparison worthwhile.
Smart move
Spring's newer master-planned communities (Gleannloch, Gleannloch West) often have HOA websites with community forums where residents share electricity plan experiences. These forums are not authoritative — one person's "best plan" may not suit your usage — but they can surface plan names worth investigating. Always check against your own usage on the search tool or calculator before switching.
Key Takeaways
Most Spring ZIP codes are CenterPoint territory — TDU charges are fixed. Spring's unincorporated geography means some peripheral addresses may fall in Sam Houston Electric Cooperative territory outside the competitive market — confirm by entering your ZIP. Usage ranges considerably by home size and era, so comparing plans at your actual summer usage level rather than 1,000 kWh is the most reliable path to the lowest bill.
