Full title and description

Energy management system application program interface (EMS-API) - Part 1: Guidelines and general requirements. This part defines the reference model, high-level guidelines and general infrastructure requirements needed to apply the EMS‑API family of standards for integrating and exchanging information between control‑centre applications and external systems.

Abstract

IEC 61970-1:2005 establishes the architectural framework and general requirements for application program interfaces used in energy management systems (EMS). It explains typical integration scenarios, describes component models and reference interfaces, and provides guidance intended to reduce integration costs, protect existing investments and improve interoperability among EMS applications and external systems. The document is technology‑neutral and serves as the foundation for the remainder of the IEC 61970 series (CIM, component interface specifications and technology mappings).

Scope

Defines high‑level guidelines and the general infrastructure required to apply EMS‑API interface standards in control‑centre and related environments. The scope includes the EMS‑API reference model, descriptions of typical application and integration scenarios, the types of applications to be integrated (real‑time operations, planning, SCADA interfaces, market interfaces), and principles for mapping component‑level interfaces and information models (CIM) into interoperable implementations. The standard focuses on interoperability across legacy and new systems and on technology‑independent architectural requirements.

Key topics and requirements

• EMS‑API reference model and architectural framework for EMS application integration.
• Guidelines for component models and component interaction patterns (services, events, data access).
• Requirements for information exchange and alignment with the Common Information Model (CIM) family (61970‑3xx).
• Descriptions of typical integration scenarios and examples of application functions to be integrated.
• Technology‑neutral interface principles, and pointers to technology mappings and CIS (Component Interface Specification) parts.
• Considerations for maintainability, reuse of existing applications, and operational concerns (including security and performance considerations at a guideline level).

Typical use and users

Used by utility system architects, EMS vendors, system integrators, control centre engineers, software developers and procurement teams when designing or procuring interoperable EMS and control‑centre solutions. It is referenced when defining integration strategies, specifying component interfaces, or planning migration from legacy systems to standards‑based architectures.

Related standards

Part of the IEC 61970 series and intended to be used alongside: IEC 61970-2 (glossary), the 61970-3xx Common Information Model (CIM) parts (for the information model), the 61970-4xx Component Interface Specification family, and the 61970-5xx technology mappings. It is also related to IEC 61968 (distribution interfaces) and to IEC 61850 (substation communications) in the broader smart‑grid interoperability landscape.

FAQ

Q: What is this standard?

A: IEC 61970-1:2005 is Part 1 of the EMS‑API series and provides guidelines and general requirements for application program interfaces used in energy management systems.

Q: What does it cover?

A: It covers the EMS‑API reference model, component and integration guidelines, typical application scenarios, and the general, technology‑neutral requirements needed to apply the rest of the 61970 series (CIM, CIS and technology mappings).

Q: Who typically uses it?

A: Utility architects, EMS/control‑centre vendors, integrators, system engineers and procurement/specification teams use it to design interoperable EMS solutions and to specify interfaces between applications and external systems.

Q: Is it current or superseded?

A: IEC 61970-1 was published in December 2005 (edition 1.0). It remains the base guideline document for the EMS‑API family; users should check the IEC catalogue for any amendments, later editions or stability/maintenance status for this part. The IEC webstore lists the original publication details and the maintained stability date.

Q: Is it part of a series?

A: Yes — it is Part 1 of the IEC 61970 series. Other parts include Part 2 (glossary), the 3xx CIM parts, 4xx Component Interface Specifications and 5xx technology mappings. The series is published by IEC TC 57 and is intended to be used together to achieve EMS interoperability.
