Why this exists
Every Texas electricity plan advertises an "average price per kWh" at three usage levels: 500, 1,000, and 2,000 kWh a month. Those numbers are real, but they're often not what you'll actually pay. Real homes don't use the same amount of electricity every month. A Texas summer pushes many homes well past 2,000 kWh, while a mild spring month can land near 500. A plan that looks cheap at whichever level PowerToChoose happens to show can cost noticeably more once your real seasonal usage runs through it.
Some plans add another wrinkle: a bill credit that only kicks in once you cross a usage threshold, say $50 off if you use 1,000 kWh or more. That can mean a month where you use a little less than the threshold costs you more than a month where you use a little more. It's a real, disclosed plan feature, not a trick, but it's easy to miss when you're reading an Electricity Facts Label for the first time.
Kilowise works out the number that actually matters: what a plan would cost you, given your own month-by-month usage. It uses the same public data as Texas's official comparison site (PowerToChoose), runs a real month-by-month simulation, and, on plans whose Electricity Facts Label it can read closely enough, flags usage-threshold credit cliffs directly, in dollars.
What it does
Enter your zip code and your monthly usage, either typed in month by month or filled from a quick estimate, and Kilowise ranks every plan available where you live by real computed yearly cost. Already have a renewal or loyalty offer from your current provider that never showed up on the public comparison site? Type in its numbers and see how it compares, with no account and nothing to upload.
What it doesn't do
Kilowise reads the same public disclosures every plan is required to publish. It doesn't check pricing with each provider directly, and it isn't affiliated with the Public Utility Commission of Texas, PowerToChoose, or any electricity provider. A missing cliff-warning badge means Kilowise hasn't found a cliff the way it currently reads that plan, not that the plan has none. Always read a plan's actual Electricity Facts Label before enrolling, especially on anything with an early termination fee. The methodology page covers how the estimate is built and where it has limits, and the sources page lists every public record the site relies on.
Texas only, for now. Texas has a mature deregulated market with one official public comparison source, which is what makes an independent, real-usage comparison tool practical to build well.
