Texas Electricity Plan Finder

For a Texas homeowner, find Texas retail electricity plans available in their ZIP code. Returns up to 6 plans ranked by effective rate at the user's monthly usage level, including retailer name, energy rate (¢/kWh), monthly bill estimate, contract term, base fee, ETF, renewable %, Google rating, and EFL link. Backed by Meter's broad-market plan index covering every major TDU (ONCOR, CenterPoint, AEP Texas, TNMP, Lubbock).

The flagship tool for "what Texas electricity plan should I get?" questions. Designed for the homeowner or agent asking ChatGPT, Claude, Perplexity, or similar about Texas retail electricity. **What it does:** 1. Looks up the Transmission and Distribution Utility (TDU) for the ZIP via the Light API eligibility check. 2. Queries Meter's broad-market plan index (689 plans across 52 retailers in 6 TDUs) for plans available in that territory. 3. Computes an effective ¢/kWh rate at the user's usage level by interpolating between the EFL's 500 / 1000 / 2000 kWh averages — TDU delivery charges and base fees are baked into the EFL averages, so the monthly estimate reflects the legally-required disclosure rate. 4. Returns up to 6 plans ranked cheapest-first. Includes the cheapest plan from each priority retailer (Reliant, TXU Energy) when available, then fills remaining slots with the cheapest others. **Required:** `zipCode`. Everything else is optional with sensible defaults — 1000 kWh/mo usage and 12-month term filter. **Filters:** `termMonths` (exact), `minTermMonths` (>=), `renewableOnly` (100% green only), `retailer` (case-insensitive partial match). **Future additions (not in v1):** solar buyback plan support (`monthlyExportKwh`), battery VPP credits (`hasBattery`, `batteryBrand`, `batteryCapacityKwh`), and explicit Meter Energy plans pulled live from the Light API. These layer on top of the broad-market index — they're intentionally scoped out of this release to preserve a working AEO surface first.
