Cheapest Plano electricity rates — July 2026

Ranked for a Plano year, not a round number

Plans here are ordered by what twelve months cost rather than by the price at one usage point, using the ERCOT residential load profile for the North Central weather zone that Plano sits in. That profile puts a state-average home's 13,800 kWh a year where Plano actually uses it: a peak near 1,882 kWh in August against roughly 741 kWh in March.

The yearly total is much the same across Texas — it's the shape that differs, and the shape is what the advertised rate hides. Rates are quoted at exactly 1,000 kWh, so a plan whose price depends on where usage lands (a bill credit that only triggers above that mark, a fee that only applies below one) can look cheap at the quoted point and cost more across a real year. A plain fixed-rate plan charges the same whenever the kilowatt-hours arrive, and for those the ranking barely moves. It moves here: the plan that wins on the advertised 1,000 kWh number, SimpleSaver 12, is not the cheapest once a full Plano year is priced.

What the numbers mean

"Per month" is the yearly total divided by twelve, not the cost at any one usage level — a real Plano August costs far more than a real February, and the average is what you can budget against. "Effective rate" is that yearly total divided by the year's kWh, which is the only cents-per-kWh figure that survives contact with a seasonal bill. "Catches" counts the pricing gimmicks detected in each plan's Electricity Facts Label: bill-credit bullseyes, minimum-usage fees, required autopay or hardware. Open any plan for the full breakdown.

Your own home is not the state-average home. If you know your real usage, enter it on the comparison tool and every plan re-ranks against your actual bills.
