What these plans really cost at your usage
Texas's cheapest-looking plans only win if you use almost exactly 1,000 kWhevery month — which real households don't.
That low headline rate comes from a bill creditthat lands only at 1,000 kWh. We'll be straight: at exactly 1,000 kWh the bill-credit plan really is cheaper. But a real Katyhome swings between months — a mild spring (500 kWh) and a summer of AC (2,000 kWh) — and at those usages the "cheap" plan costs more than our honest flat-rate pick. See for yourself across three real usage levels.
Just Energy
Sustainable Days Bundle - 6 · 6-month fixed
11.7¢/kWh
Roughly the same at any usage — no 1,000-kWh trick.
Budget Power
Prime 12
6.8¢/kWhonly at exactly 1,000 kWh
Its real per-kWh rate swings with usage (below).
| Monthly usage | Honest pick (¢/kWh · bill) | Bill-credit plan (¢/kWh · bill) |
|---|---|---|
| 500 kWh (light) | 12.7¢ · $64 | 19.8¢ · $99 |
| 1,000 kWh (exact target) | 11.7¢ · $117 | 6.8¢ · $68 |
| 2,000 kWh (heavy / summer AC) | 11.3¢ · $226 | 12.8¢ · $256 |
The honest read: the bill-credit plan is only the cheapest if you land almost exactly on 1,000 kWh every month. A typical Katy household closer to 1,000 kWh pays about $117 on our flat pick versus roughly $198on the bill-credit plan once its credit doesn't apply. We rank the plan that's actually cheapest for real usage — not the lowest headline number.
