Utility Rate Plan Exchange

An open semantic standard for representing and exchanging utility customer rate plan data in a structured, machine-readable format

An LF Energy Project

LF Energy URPX

The Problem

Utility rate plans are locked in PDFs and proprietary formats — impossible to process automatically or compare across utilities.

The Solution

URPX defines a shared RDF/OWL ontology that transforms rate plan data into structured, interoperable, machine-readable semantic graphs.

The Impact

Enables automated rate comparison, accurate bill simulation, DER optimization, and regulatory compliance tooling across the industry.

Semantic Web Native

Built on RDF, OWL 2, and SHACL. Classes, properties, and relationships are formally defined and machine-readable.

Standards Aligned

Maps to Green Button, LF Energy CDS, IEC CIM, and schema.org. One standard, many integrations.

LF Energy Project

Community-developed with working group oversight and supported by LF Energy. Published under open licenses: W3C Document License, CDLA-Permissive-2.0 and Apache-2.0 by file category.

Milestones
