Texas Solar Buyback Plan Catalog

Return the current catalog of solar buyback plans available in Texas, across every deregulated TDU (Oncor, CenterPoint, AEP Texas Central, AEP Texas North, TNMP, Lubbock Power & Light). Includes Meter Energy plans (fetched live from the Light API) plus competitor plans (TXU, Reliant, Octopus, Rhythm, Gexa, Cirro, Champion, and others). For each plan: provider name, plan name, TDU, contract term, import rate (¢/kWh), export buyback rate, base fee, ETF, estimated annual cost at a default profile, battery program support, signup URL, and source URL. Optional filters: tdu, providerType, termMonths.

A developer-facing data feed of every Texas solar buyback plan Meter tracks. Backed by the same engine that powers the public JSON feed at `/data/texas-solar-buyback-plans.json` and the markdown feed at `/data/texas-solar-buyback-plans.md` — surfaced here as a callable tool so it shows up in the discovery manifest, OpenAPI spec, and any MCP host that connects via `/api/mcp/{app}`. **What you get:** - `plans` — array of solar buyback plans. Each row is a (provider × plan × TDU) tuple with import rate, export rate, base fee, ETF, term length, estimated annual cost at a default profile, battery program support, and source/signup URLs. - `tduReferences` — representative ZIP code for each Texas TDU. Useful for downstream lookups against `get-utility-for-zip` or `get-tdu-delivery-rates`. - `assumptions` — the default energy profile used to compute `estimatedAnnualCostDollars`. Override these client-side if you have the customer's actual usage shape. - `sourceStatus` — per-source freshness and coverage status. Always inspect this before treating a TDU slice as complete; competitor coverage is partial outside Oncor and CenterPoint today. - `methodology` and `publisher` — provenance for citation. **Use cases:** - Build a "compare Texas solar plans" page or quote engine. - Power AI agents that recommend a plan and need real, current rate data. - Audit a homeowner's current plan against alternatives. - Track competitor pricing over time (the feed updates as Meter's underlying `formatted_plans` table refreshes). **Filters:** all optional. Omit all three to get the full catalog. - `tdu` — case-insensitive partial match on display name (e.g. "Oncor", "CenterPoint", "AEP Texas Central"). - `providerType` — `meter` for Meter Energy plans only, `competitor` for everything else. - `termMonths` — exact contract length filter (e.g. 12, 24, 36). **Methodology notes:** - Meter plans are fetched live from the Light API using one representative ZIP per TDU. Rates are real-time. - Competitor plans are read from Meter's `formatted_plans` dataset and costed with the same engine the public `/solarbuybackplans` comparison page uses. - `estimatedAnnualCostDollars` assumes a default solar homeowner profile (700 kWh imported and 700 kWh exported per month, 40% of imports at night, no battery). For personalized estimates, post the profile fields you have to `/api/v1/plan-cost-calc`. This is an audience-4 (developer / agent) tool. For a ranked homeowner-facing recommendation given a ZIP, use `find-electricity-plan` instead — it does the ZIP-to-TDU lookup and ranks the cheapest plans for the user's stated usage.

Inputs

  • tdustring

    Optional filter on TDU (Transmission and Distribution Utility) display name. Case-insensitive partial match. Examples: 'Oncor', 'CenterPoint', 'AEP Texas Central', 'AEP Texas North', 'TNMP', 'Lubbock Power & Light'. Omit to return plans from every TDU.

  • providerTypeenum<meter | competitor>

    Optional filter on provider type. 'meter' returns only Meter Energy plans. 'competitor' returns only non-Meter plans (TXU, Reliant, Octopus, Rhythm, Gexa, Cirro, Champion, and others). Omit to return both.

  • termMonthsnumber

    Optional filter on exact contract length in months. Typical values: 12, 24, 36. Omit to return every term length.

Outputs

  • nameany

    Catalog identifier.

  • generatedAtstring

    ISO 8601 timestamp the catalog was assembled.

  • validThroughstring

    ISO 8601 timestamp after which the catalog should be re-fetched. The underlying feed revalidates hourly.

  • publisherobject

    Catalog publisher and provenance metadata.

  • methodologyarray<string>

    Bullet points documenting how the catalog is assembled. Cite these when summarizing the data.

  • assumptionsobject

    Default profile used to compute estimatedAnnualCostDollars.

  • tduReferencesarray<object>

    Representative ZIP and landing URL for each Texas TDU.

  • sourceStatusarray<object>

    Per-source freshness and coverage status. Inspect before treating a TDU slice as complete.

  • recommendedPagesarray<object>

    Public pages on meterplan.com to link to for human readers and follow-up workflows.

  • plansarray<object>

    Solar buyback plan rows after applying any filters from the input. Sorted by TDU, then by estimated annual cost ascending, then by provider and plan name.

  • filterobject

    Echo of the filter inputs alongside before/after plan counts. Useful for confirming a filter narrowed the catalog as expected.
