Full title and description

Systems interface between customer energy management system and the power management system — Part 10-1: Open automated demand response (IEC 62746-10-1:2018). This International Standard specifies the OpenADR 2.0 profile for two‑way signalling between service providers/aggregators (VTNs) and automated clients at customer sites (VENs) to support demand response, pricing and distributed energy resource (DER) communications.

Abstract

IEC 62746-10-1:2018 defines a minimal data model and set of services to enable automated demand response (DR), dynamic/pricing signals and DER management. Resources (loads, generation, storage) may be addressed individually or as aggregated virtual resources. The standard describes roles and messaging between virtual top nodes (VTNs) and virtual end nodes (VENs), and includes profile schemas to support implementation and conformance testing. XML schema files are provided with the publication to support implementations.

Scope

Specifies the Open Automated Demand Response (OpenADR 2.0) profile as an interoperable, vendor-neutral interface between customer energy management systems and power/market operators. The scope covers data models and services for DR events, pricing signals and DER coordination, how VTNs publish information and VENs subscribe/respond, and optional transport/security considerations. Implementation artefacts including XML schemas (profile/schema files) are provided to enable conformance and implementation. The standard makes no assumption about internal facility control strategies or contractual arrangements between market participants and customers.

Key topics and requirements

• OpenADR 2.0 profile: message types, event lifecycle and feature profiles (profiles A/B etc.).
• Data models for DR events, signals, resource definitions (individual and aggregated/virtual resources).
• Roles and interactions: Virtual Top Node (VTN) and Virtual End Node (VEN) messaging patterns.
• Transport and security considerations (recommended mechanisms and integration points) and references to security practices.
• XML schema and conformance artifacts (schemas provided as part of the publication to support implementers and testing).
• Requirements for subscription, event notification, reporting and state management for DR/DER operations.

Typical use and users

Used by electric utilities, independent system operators, aggregators, energy service providers, vendor and system integrators of building and facility energy management systems, manufacturers of DER and control systems, and regulators coordinating demand response programs. Typical deployments include automated DR programs, price-responsive load management, aggregated DER dispatch, and integration of customer-side resources into market/grid services.

Related standards

Relevant related publications include the earlier IEC PAS 62746-10-1:2014 (OpenADR 2.0b profile specification) which was replaced by IEC 62746-10-1:2018, other parts of the IEC 62746 family such as IEC 62746-10-3:2018 (adapting smart grid user interfaces to the IEC CIM), and architecture/guidance in IEC TS 62746-3:2015. Implementers commonly reference related security standards (for example the IEC 62351 series) and CIM mappings where integration with utility systems is required.

FAQ

Q: What is this standard?

A: IEC 62746-10-1:2018 is an International Standard that formalizes the Open Automated Demand Response (OpenADR 2.0) profile to enable standardized two‑way signalling between grid/market operators (or aggregators) and automated customer-side systems for DR, pricing and DER coordination.

Q: What does it cover?

A: It covers data models, service definitions, message flows and implementation artefacts (including XML schemas) required to publish DR/pricing/DER signals from VTNs and for VENs to subscribe, respond and report; it does not mandate internal facility control strategies or commercial contracts.

Q: Who typically uses it?

A: Utilities, aggregators, energy service companies, equipment and software vendors for building/facility energy management, DER manufacturers, system integrators and agencies running demand response programs.

Q: Is it current or superseded?

A: IEC 62746-10-1:2018 is the current International Standard edition (published 19 November 2018) and it replaced the earlier IEC PAS 62746-10-1:2014. IEC lists a stability date for the 2018 edition through 2026.

Q: Is it part of a series?

A: Yes — it is part of the IEC 62746 family (systems interface between customer energy management system and the power management system). Other parts address architecture, CIM adaptation and additional interface aspects (for example IEC TS 62746-3:2015 and IEC 62746-10-3:2018).

Q: What are the key keywords?

A: OpenADR, demand response (DR), VTN, VEN, DER, XML schema, interoperability, smart grid, customer energy management.
