Modernizing Utility
Rate Plan Infrastructure
Structured, standards-based rate plan data, ready for your cost models, your product, and your customers. Built on URPX, the Utility Rate Plan eXchange, the open standard backed by Linux Foundation Energy.
The problem
The rate plan data you need is genuinely hard to get.
The source data was never built to be used by machines, so every project starts by building data sets and models by hand, buying them, or estimating cost with default values.
Locked in PDFs
Rate plans live in long PDF filings: hundreds of pages, no shared format, and nothing a machine can read reliably.
Rebuilt every time
Teams re-transcribe the same plans into spreadsheets and code for every new project, at about 20 hours per rate plan.
Numbers drift from the bill
Models fall back on averages, so the savings you show a customer can land 10–20% off what the real bill says.
Why it matters
Make the data trustworthy, and you can do science.
Putting rate plan data out there isn't enough. It has to be structured the same way everywhere, so a cost calculation can be repeated, checked, and trusted. Get that right and the work stops being guesswork: you can compare, verify, and build on each other's numbers. That is the point of doing it in the open. Fixing it for us, and fixing it for everybody.
The solution
An open standard, and the managed platform built on it.
Open standard
URPX
The Utility Rate Plan eXchange, an open standard hosted by LF Energy.
- ✓ Free and open source, Apache-2.0 licensed
- ✓ Open governance under LF Energy
- ✓ No vendor lock-in: your data stays portable
- ✓ Machine-readable JSON-LD with formal schema validation
Managed platform
UtiliPub™
The managed cloud platform for working with URPX rate-plan data at scale, built by Flux Tailor.
- ✓ White-label public rate plan libraries: your data, your brand
- ✓ Searchable private libraries with the Explorer app
- ✓ Cost-modeling API: scenario in, eligible options and cost out
- ✓ URPX JSON-LD export and webhook update alerts
Who it's for
Built for the teams who work with rate plan data.
Utilities and publishers
Your rate plans live in PDF filings no one downstream can use without re-keying them. Publish that data once, in a standard format, under your own brand: a white-label library your customers, regulators, and partners can actually read.
Regulators and commissions
Comparing plans across utilities means reading hundreds of pages by hand. Get the same structured data from every publisher, searchable and comparable in one place, with an accessible PDF rendering when the record is what counts.
Product and data teams
Every project starts by rebuilding the same rate plans into spreadsheets and code, about 20 hours each. Query validated rate plan data straight from the API instead: GraphQL in, URPX JSON-LD out.
Cost modelers and analysts
Lean on averages and the savings you show a customer can land 10–20% off the real bill. Model from the same prices the bill is built on: a scenario goes in, eligible options and cost come out.
Available today
A white-label rate plan library, ready to go public
Library Public serves your rate plan data to the world: a public API, a public GUI, and embeddable widgets that run in utility and regulator websites under your own brand. This is where born-digital publication starts: structured URPX data at the source, searchable and comparable in the Explorer, with every record exportable as the same URPX document your systems consume directly.
API-first
An API your tools can call
Query validated rate plan data straight from the UtiliPub read API: GraphQL, typed, paginated. The same catalog that powers the app powers your integration.

Your data stays yours
Your rate plan library is standard URPX: portable, not trapped in one vendor's format. If you ever leave UtiliPub, your data stays usable and standards-compliant. Unlike proprietary data vendors, you keep sovereignty over your data.
The full platform
Every layer, one lifecycle.
UtiliPub is built for utility-driven, born-digital rate plan publication: rate plans authored digitally at the source, not scraped from PDFs after the fact. Explorer, Library, and the cost-modeling API are joined by three more layers that complete the loop.

Author
Studio
Author and validate your own URPX rate plans to complete your catalog where public feeds don't reach.
Publish
Publisher
Publish rate plans born-digital using URPX, with validation, data lineage, and accessible PDF renderings as compliance outputs.
Validate
Calibrator
Map real bill line items to the URPX charges that explain them, and validate cost models against actual bills.
