IEC TS 62325-504-2015 PDF

Full title and description

Framework for energy market communications - Part 504: Utilization of web services for electronic data interchanges on the European energy market for electricity. The Technical Specification defines WSDL-based web services (applying the Basic Web Service Pattern from IEC 61968-100) to support near‑real‑time, secure electronic data interchange between actors on the European electricity market (services such as List Messages, Get Message and Put Message).

Abstract

This Technical Specification (IEC TS 62325-504:2015) specifies a web‑services-based framework for exchanging market messages in the European Energy Market for Electricity (EME). It defines service operations, message filters and basic schema/WSDL constructs intended to enable interoperable, secure, near‑real‑time message exchange between market participants and can be applied to related integration scenarios (for example gas market systems or broader enterprise integration). Core service types described are List Messages, Get Message and Put Message.

Scope

Defines the web services (WSDL) and accompanying schemas and service contracts required to support electronic document/message interchange on the European electricity market in a fast (near‑real‑time) and secure manner. The scope explicitly includes applicability to integration tasks beyond IEC 62325-451 (for example gas market integration or general enterprise integration) and covers service definitions, WSDL abstract definitions, schema fragments and conformance guidance for the three core service operations.

Key topics and requirements

• Definition of three primary web services for market messaging: List Messages, Get Message and Put Message (filters, time/interval parameters and message identification patterns).
• WSDL abstract service definitions and XML schema fragments to support message payloads and transport.
• Use of the Basic Web Service Pattern implementation profile from IEC 61968-100 to ensure compatibility with existing utility web service approaches.
• Security and transport considerations referenced through relevant standards (TLS/SSL guidance, XML Signature / X.509 certificate profiles referenced in normative/informative references).
• Conformance and filtering rules (time-interval vs server timestamp, message-type and owner filters, optimization notes for incremental retrieval).

Typical use and users

Implementers and architects of market communication platforms for transmission system operators (TSOs), power exchanges, market operators, market participants, integration vendors and system integrators who require an interoperable SOAP/WSDL-based interface for exchanging market messages. Also of interest to organizations evaluating CIM-based interchange solutions or integrating market systems with enterprise IT.

Related standards

Part of the IEC 62325 series (CIM-based market communications). Closely related documents include IEC 62325-301 (CIM extensions for markets), IEC 62325-351 (European market model exchange profile), IEC 62325-450/451 series (profile and contextual models), and other market exchange parts such as IEC 62325-503 (market data exchanges). Implementations are intended to align with IEC 61968-100 web service pattern and use XML/WSDL/X.509 and related IETF/W3C building blocks referenced in the TS.

FAQ

Q: What is this standard?

A: IEC TS 62325-504:2015 is a Technical Specification that defined WSDL/SOAP web services and supporting schemas to enable near‑real‑time, secure electronic message exchange between participants in the European electricity market.

Q: What does it cover?

A: It covers the definition of service operations (List Messages, Get Message, Put Message), service request/response parameter semantics, WSDL abstract definitions, schema fragments and conformance notes for exchanging market messages using web services. Security, timestamping and filtering semantics are addressed by referencing established IETF/W3C standards.

Q: Who typically uses it?

A: TSOs, power exchanges, market operators, vendors and system integrators building or operating market communication nodes or gateways that require an interoperable web‑services-based message exchange interface.

Q: Is it current or superseded?

A: IEC TS 62325-504:2015 was published in 2015 and the IEC webstore lists it as withdrawn (withdrawal date shown by IEC: 31 January 2023). Users should treat the document as withdrawn and check the IEC webstore or national adoption bodies for any replacement or newer guidance before planning new implementations. Other parts of the IEC 62325 family (for example IEC 62325-503:2018) remain active and may provide alternative messaging approaches.

Q: Is it part of a series?

A: Yes — it is part of the IEC 62325 series (Framework for energy market communications) which contains CIM extensions, profiles and business process/contextual models (e.g., parts -301, -351, -450 and the -451 series). The series is maintained under IEC TC57.

Q: What are the key keywords?

A: Web services, WSDL, CIM, energy market communications, List/Get/Put messages, near‑real‑time messaging, IEC 62325, TC57.
