Electricity plan data for AI agents and developers

Every city and ZIP rates page on powerplans.com has a JSON version with the same live plans, prices, and terms. No key or sign-up is needed.

What you can read

Add .json to a city or ZIP rates page URL to get the same plans as JSON:

Every city and ZIP rates page has one. Pages that list plans link to it in a "For a machine-readable version for AI agents" note under the list, and every one links to it in a <link rel="alternate" type="application/json"> tag. Other pages, including the Texas state page, guides, and tools, don't have a JSON version yet.

Prices differ by utility. When a ZIP is served by more than one, its JSON lists the utilities under utility_choice, each with its own URL ending in ?utility=, the same as the page asks which utility is on the bill.

In areas without retail choice, such as Austin and San Antonio, the response says so (retail_choice: false) and links to the guide for starting service there.

Reading a response

Each response describes itself: field names carry their units, and its about section explains how prices and order work. A few things worth knowing:

  • catalog_status: "unavailable" means prices are updating, so plans is empty for now. Try again in a few minutes.
  • how_to_choose lists what we think matters besides price, such as the home's equipment and how long the price is fixed, with the plan fields that speak to each.
  • Each plan's sign_up.url opens powerplans.com with that plan's sign-up step, where the price is checked again and the person enters their own details. If you can, add utm_source= with your name so we know where people came from.

The format may change as the site does, so read it fresh rather than relying on a fixed schema.

Using the data

Every plan for the area is listed: standard plans first, then plans for homes with solar, a battery, or an EV, which the page shows only once the person says the home has that equipment. What fits a household depends on its usage, its equipment, and what it values.

Light is the retail electricity provider that powers the plans on powerplans.com, including those offered with a partner's brand. Learn more on the about page.
