Overview
IEC TR 62325-103:2017 is a Technical Report that reviews information exchanges in the deregulated European-style retail energy market from a CIM (Common Information Model) perspective. The report explains how the ebIX® information model (European forum for energy Business Information eXchange) can be mapped to CIM, identifies gaps, and proposes CIM extensions needed to fully support market-centric exchanges among retail market actors. It focuses on practical interoperability for market communications, settlement, billing and metering data exchange.
Key topics and technical requirements
- Mapping ebIX to CIM: Methodology and class-diagram mappings that translate ebIX message structures into CIM constructs for consistent data modelling.
- Use cases covered: Collected metering data, reconciliation, imbalance settlement, billing, labeling, calorific value exchange, meter-read determination, change of supplier, change of balance responsible party, and notifications of metering point/configuration characteristics.
- CIM extensions proposed: Additions and attribute updates for classes such as MarketEvaluationPoint, MktActivityRecord, UsagePoint, and TimeSeries to support retail-specific workflows.
- Linking metering artifacts: Recommendations for linking meters, registers, readings and time series to preserve traceability of measurement and aggregated volumes.
- Aggregation & settlement needs: Definitions to specify aggregation criteria, meter timeframes for quantities and prices, and price-volume combinations for reconciliation and settlement.
- Addressing and metadata: Enhancements to represent addresses and request references in time series and metering exchanges.
Keywords: IEC TR 62325-103:2017, CIM mapping, ebIX, MarketEvaluationPoint, MktActivityRecord, TimeSeries, UsagePoint.
Applications and who uses this standard
- Utilities and suppliers: Ensures consistent exchange of meter reads, billing volumes, calorific values and supplier change notifications.
- Market operators and aggregators: Supports imbalance settlement, reconciliation and price-volume reporting using harmonized CIM models.
- Software vendors & system integrators: Guides implementation of interoperable IT systems that translate ebIX messages to/from CIM-based models.
- Regulators and standards architects: Helps assess conformity to EU-directed market rules and harmonized retail information exchanges.
Practical benefits include improved interoperability, reduced integration costs, traceable metering data across processes (billing, settlement, labeling), and faster supplier switching.
