What is ODS-E?

ODS-E (Open Data Schema for Energy) is an open standard for normalizing distributed energy data across OEM platforms.

It gives operators, integrators, and utilities a shared data model so telemetry from Huawei, Enphase, Solarman, and other systems can be transformed into one consistent schema for analysis, validation, and reporting.

Why It Exists

Energy data is fragmented across vendor-specific APIs, file formats, and error taxonomies.

ODS-E removes that fragmentation by defining:

• A common JSON schema for energy records
• A normalized error taxonomy for cross-OEM fault interpretation
• A transform layer to convert OEM-native payloads into ODS-E records

Core Building Blocks

1. Schema

A minimal, machine-validatable record format with required fields such as timestamp, energy, and error classification.

{
  "timestamp": "2026-02-05T14:00:00Z",
  "kWh": 847.5,
  "error_type": "normal",
  "PF": 0.98
}

2. Transforms

Declarative mappings that convert OEM exports and APIs into ODS-E-compliant records.

3. Validation

Schema and semantic checks that ensure records are structurally valid and operationally meaningful.

Who Uses ODS-E

• IPP operators managing multi-site, multi-OEM portfolios
• ESCO and O&M teams building standardized monitoring pipelines
• Utilities ingesting DER production data for forecasting and dispatch
• Analysts, insurers, and finance teams requiring comparable energy datasets
