1. The High Usage Advantage
Fixed costs matter less. Base charges and TDU fixed fees get spread across more kWh, lowering your effective rate.
Bill credits actually work. If you consistently use 2,000+ kWh, you'll hit credit thresholds reliably and get the advertised low rate.
| Monthly Usage | Fixed 9.8¢ Plan | Bill Credit Plan (14.2¢ + $75 at 1,000) |
|---|---|---|
| 2,500 kWh | $297 | $280 — saves $17/month |
| 2,000 kWh | $248 | $234 — saves $14/month |
| 1,500 kWh | $199 | $266 — costs $67 MORE |
The breakeven: At 2,000+ kWh, bill credit plans start to win. Below that, fixed rate is safer.
2. Plan Types Ranked for High Usage
Tier 1: Bill Credit Plans (if you hit threshold reliably)
Best for: Homes using 2,000+ kWh every month, including winter. - Look for large credits ($75-100) at achievable thresholds - Verify you exceed the threshold in your lowest usage month - Calculate the annual cost including months where you might miss
Tier 2: Fixed Rate Plans
Best for: Homes using 1,500-2,000 kWh or with variable monthly usage. - Predictable cost every month - No risk of missing a threshold - Slightly higher annual cost than a well-matched bill credit plan
Tier 3: Tiered Plans (sometimes)
Best for: Very high usage (2,500+ kWh) if the top tier rate is competitive. - Check the tier breakpoints carefully - Some tiered plans have the best rates at 2,000+ kWh - Read the EFL — tier structures vary wildly
Avoid: Free Nights Plans
Even at high usage, unless your smart meter data shows 50%+ nighttime consumption. The daytime rate (14-16¢) on 1,500+ kWh of daytime usage is brutal.
3. Managing Summer vs. Winter Swings
High-usage homes have the biggest seasonal swings:
| Month | Typical High-Usage Home |
|---|---|
| January | 1,400 kWh |
| April | 1,200 kWh |
| July | 2,800 kWh |
| August | 3,000 kWh |
| October | 1,600 kWh |
The danger zone: Spring and fall months might drop below a bill credit threshold. If your March usage is 1,100 kWh on a 1,500 kWh threshold plan, you lose the credit.
Strategy: Compare annual cost, not monthly rate. Model every month against the plan structure. Or upload your bill and let us simulate it.
4. Reducing Usage (If You Want To)
Sometimes the cheapest kWh is the one you don't use: - Smart thermostat: 10-15% savings on cooling. Set schedules, raise temp when away. - Seal air leaks: Weatherstripping around doors and windows. Biggest bang for buck. - Attic insulation: Especially in homes built before 2000. Can reduce cooling costs 15-20%. - Pool pump timer: Run during off-peak hours, reduce daily run time to 6-8 hours. - LED lighting: Small impact individually, but it adds up in high-usage homes with lots of fixtures.
Reality check: In a Texas summer, AC is 60-70% of your bill. No amount of LED bulbs offsets a poorly insulated home.

What usage level makes bill credit plans worth it?
Generally 2,000+ kWh every month, including your lowest month. If you drop below the threshold even 2-3 months per year, a fixed-rate plan is usually cheaper overall. Check your last 12 months of bills to be sure.
Are longer contracts better for high usage homes?
It depends on the rate. A 24-month contract locks in your rate longer, protecting against market increases. But if rates drop, you're stuck. For high-usage homes, a 1-2¢/kWh difference in rate translates to $20-40/month, so the contract rate matters a lot.
Should I get a home energy audit?
If you're consistently above 2,500 kWh/month, yes. Many TDUs offer free or subsidized energy audits. The biggest finding is usually inadequate attic insulation or duct leaks — fixes that can pay for themselves in 1-2 summers.
