Full title and description

IEC 62325-451-3:2014/A1:2017 — Framework for energy market communications — Part 451-3: Transmission capacity allocation business process (explicit or implicit auction) and contextual models for European market. This entry covers Amendment 1 (2017) to the first edition (2014) and the consolidated CSV edition that combines the base edition and the amendment for implementers of European-style electricity market communications.

Abstract

This part of IEC 62325 specifies a package to support transmission capacity allocation business processes — both explicit and implicit auctions — and provides the associated document contextual models, assembly models and XML/CSV schema for use in European market implementations. It contextualises aggregate core components from IEC 62325-351 into aggregated business information entities (ABIEs) and assembles those into document contextual models to enable consistent messaging and data exchange between market participants and transmission system operators.

Scope

This standard specifies the information models, contextualisation and message assembly necessary to support transmission capacity allocation business processes used in European-style electricity markets. It covers both explicit and implicit auction processes, defines contextualised ABIEs derived from IEC 62325-351 ACCs, and provides document contextual models together with XML/CSV schema to enable interoperable exchange between market systems, TSOs and other market participants. The consolidated CSV edition provides the fuller set of schemas and mappings for implementers.

Key topics and requirements

• Definition of business processes for transmission capacity allocation via explicit and implicit auctions.
• Contextual models and assembly models that map ACCs from IEC 62325-351 into ABIEs suited for document exchange.
• XML schema (and CSV consolidated package) for message exchange and implementation guidance for European market profiles.
• Data structures to support auction processes, capacity nomination and allocation messages between market participants and TSOs.
• Compatibility notes and updates introduced by Amendment 1 (2017) to the 2014 edition.

The above topics are presented so implementers can design interoperable market communication flows consistent with the CIM European market profile.

Typical use and users

Primary users are transmission system operators (TSOs), market operators, energy exchanges, software vendors and system integrators developing market messaging and back-office systems for European electricity markets. Regulators, consultants and testing laboratories that validate interoperability of market communications also use these models and schemas to ensure conformity with the IEC 62325 family and European market profiles.

Related standards

This part is one element of the IEC 62325 series (Framework for energy market communications). Closely related parts and normative references include IEC 62325-351 (CIM European market model exchange profile), IEC 62325-451-1, IEC 62325-451-2, IEC 62325-451-5 and other profile and mapping documents in the IEC 62325/62361 family that govern CIM to XML/CSV mappings and context modelling. Implementers should consult the broader 62325 suite for complete interoperability requirements.

FAQ

Q: What is this standard?

A: IEC 62325-451-3:2014/A1:2017 is an amendment to Part 451-3 of the IEC 62325 series that specifies the transmission capacity allocation business process (explicit or implicit auctions) and the contextual models and schemas used in European electricity market communications.

Q: What does it cover?

A: It covers the contextualisation of aggregate core components into ABIEs, document contextual and assembly models, and associated XML/CSV schema to support transmission capacity allocation messages for European market implementations, including both explicit and implicit auction mechanisms.

Q: Who typically uses it?

A: TSOs, market operators, energy exchanges, software vendors, system integrators, regulators and testing bodies involved in designing, operating or validating market communication systems in European-style electricity markets.

Q: Is it current or superseded?

A: The amendment was published on 5 May 2017 (IEC 62325-451-3:2014/A1:2017). The IEC catalogue lists the publication and the consolidated CSV edition; national confirmations and life-cycle information indicate the document remains current within the published stability period (stability/confirmation activity visible through 2026 for several national bodies). Users should check their national standards body or the IEC catalogue for the absolute current status and any later revisions beyond 2026.

Q: Is it part of a series?

A: Yes — it is one part of the IEC 62325 series (Framework for energy market communications) and is intended to be used together with other parts of the series such as IEC 62325-351 (CIM European market model) and the other 451-x parts that define contextual models for different market business processes.

Q: What are the key keywords?

A: Transmission capacity allocation; auction; explicit auction; implicit auction; CIM; ABIE; ACC; XML schema; CSV; IEC 62325; European market profile.
