Last updated: October 18, 2026 · 7 min read
Garland is one of the larger established cities in Dallas County — a working-class and middle-class community with a housing stock built primarily in the 1960s through 1990s. Older homes often have less efficient insulation and HVAC equipment than newer construction, which means electricity usage (and the savings opportunity from picking the right plan) can be significant. Every Garland address is in the deregulated ERCOT market with full access to competitive electricity plans.
The short answer
All Garland ZIPs (75040–75044, 75048) are Oncor territory — fully deregulated. Fixed-rate plans as of May 2026 typically advertise 9.0–13.5¢/kWh at 1,000 kWh. Garland's older single-family homes frequently use 1,100–1,500 kWh in summer months, and less-efficient homes can exceed 1,700 kWh. The advertised rate understates the real summer bill for most Garland households. Search by ZIP for accurate cost at your usage.
Oncor — The Fixed Delivery Layer in Garland
Oncor Electric Delivery is the TDU for Garland, serving all of Dallas County. Every Garland electricity bill includes Oncor's TDSP charges: a fixed monthly customer charge plus a per-kWh distribution charge set by PUCT tariff filings. These charges are the same for every customer in Oncor territory, regardless of which REP they use.
Oncor's charges at 1,000 kWh typically add $13–$17 to a Garland bill. At 1,500 kWh, the delivery component rises to $18–$23. Garland has no municipal utility — every residential customer is in the competitive market and can switch REPs at any time with no service interruption.
Garland's Housing Stock and What It Means for Usage
The majority of Garland's single-family housing was built between 1960 and 1995. Homes of this vintage typically have attic insulation that meets the building codes of their era — R-19 to R-30 — compared with the R-38 or higher recommended today. Older single-pane or early double-pane windows, aging HVAC systems (15+ years old are common in this market), and original ductwork all contribute to higher summer cooling loads than newer construction of equivalent size.
A 1,500 sq ft Garland home from the 1980s may use 1,200–1,500 kWh in a July heat wave. A comparable home built to 2015 standards might use 900–1,100 kWh for the same period. The older home's higher usage makes the plan's rate at the 1,000–2,000 kWh EFL range more important than the 500 kWh tier.
| ZIP | Neighborhood | Primary Housing Era |
|---|---|---|
| 75040 | North Garland / Broadway area | 1970s–1990s |
| 75041 | Central Garland | 1960s–1980s |
| 75042 | West Garland / older neighborhoods | 1960s–1970s |
| 75043 | South / Southeast Garland (Lake Hubbard area) | 1980s–2000s |
| 75044 | Northeast Garland / Firewheel area | 1990s–2010s |
A Texas example
Robert in Central Garland (75041) has a 1,350 sq ft home built in 1972. He uses 1,380 kWh in July. He picked a plan advertised at 9.9¢/kWh expecting a $136 bill. His July bill: $169.48. At 1,380 kWh, the plan's interpolated rate including a $7.95 base charge and Oncor TDSP was 12.28¢/kWh. His neighbor Anita has a 2,100 sq ft home in Northeast Garland (75044) built in 2005 and uses 1,500 kWh in July. She researched plans using the True Cost Calculator, picked a plan with a flat 10.1¢/kWh and no base charge, and her July bill was $167.20 — despite using 120 more kWh than Robert.
Finding the Most Affordable Plan in Garland
Garland households benefit significantly from comparing plans at their actual summer usage rather than the 1,000 kWh benchmark. Because Garland's older housing stock tends to drive usage above 1,000 kWh in summer, the plan's EFL pricing at 2,000 kWh — and the interpolated rate between 1,000 and 2,000 kWh — often predicts the summer bill more accurately than the advertised figure.
The search tool on the homepage applies linear interpolation across all three EFL price points (500, 1,000, and 2,000 kWh) to estimate your real bill at your actual usage. Enter your Garland ZIP and bedroom count for a ranked list of plans by true cost. For detailed month-by-month projection, the True Cost Calculator lets you enter exact monthly usage figures.
The math
A Garland plan shows 9.5¢/kWh at 1,000 kWh and 8.8¢/kWh at 2,000 kWh. At your actual August usage of 1,380 kWh, the interpolated rate is: 9.5 + ((1,380 - 1,000) × (8.8 - 9.5) / 1,000) = 9.5 - 0.266 = 9.234¢/kWh. Energy charge: $127.43. Add Oncor TDSP (~$19), taxes, and any base charge, and the real bill is approximately $152–$160. The advertised 9.5¢ at 1,000 kWh suggested a bill around $95 plus delivery — a $57–$65 underestimate.
Watch out
If your Garland home has an older HVAC system (10+ years), your electricity usage is probably above average for your home size. Replacing a SEER-10 system from 2008 with a SEER-18 unit in 2025 can reduce cooling electricity consumption by 35–45% — potentially more savings per year than switching electricity plans alone can achieve. Both strategies compound: a more efficient home on a lower-rate plan produces the best outcome.
Smart move
Texas's Weatherization Assistance Program (WAP), administered by the Texas Department of Housing and Community Affairs, provides free attic insulation, weather stripping, and HVAC tune-ups for income-qualifying households. Garland's older housing stock makes it one of the cities where this program can deliver the most benefit. Check eligibility at tdhca.state.tx.us before paying for energy efficiency upgrades out of pocket.
Key Takeaways
All Garland ZIP codes are Oncor territory — TDU delivery charges are fixed and identical regardless of REP. Garland's older housing stock drives summer usage above 1,000 kWh for most single-family households, making the advertised EFL rate at 1,000 kWh an unreliable bill predictor. Compare plans at 1,200–1,500 kWh for a more accurate picture of your real summer cost.

How can I lower my Garland electricity bill?
The two most impactful steps are: (1) switch to a competitively priced fixed-rate plan if you are on a holdover or variable rate, and (2) compare plans at your actual typical usage level rather than the 1,000 kWh advertised benchmark. Garland's older housing stock often benefits from additional weatherization — attic insulation and window sealing can meaningfully reduce cooling loads and therefore the kWh you are paying for regardless of plan.
