IEEE Std 1547-2018 (Revision of IEEE Std 1547-2003)

IEEE Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces


This standard provides interconnection and interoperability technical and test specifications and requirements for distributed energy resources (DERs). Additionally, several annexes are included in this standard that provide additional material for informative purposes, but are not required to be used in conjunction with this standard.


This standard establishes criteria and requirements for interconnection of distributed energy resources with electric power systems (EPSs) and associated interfaces. The stated technical specifications and requirements are universally needed for interconnection and interoperability of distributed energy resources (DERs) and will be sufficient for most installations. The specified performance requirements apply at the time of interconnection and as long as the DER remains in service.


This document provides a uniform standard for the interconnection and interoperability of distributed energy resources with electric power systems. It provides requirements relevant to the interconnection and interoperability performance, operation and testing, and, to safety, maintenance and security considerations.

SCC21-Reviewed Slide Decks Available for Interested Lecturers

As part of our SCC21 outreach for IEEE Std 1547-2018, SCC21 is happy to provide interested lecturers with pre-reviewed slide decks for presentations on the new IEEE 1547 under the condition of mutual collaboration. That will save presenters time, maintain consistency in the presentations, and enable continuous improvement of the new standard. Presenters that use SCC21-reviewed slides agree to conform to the SCC21-approved outreach procedures for standards presentations available at this link:

Education and Training Resources

All resources represent the authors’ views and are not the formal position, explanation or position of the IEEE, IEEE Standards Association, IEEE Standard Coordination Committee 21, or any of the SCC21 Officer’s affiliations. Resources tagged with “SCC21-Reviewed” have been peer-reviewed by SCC21 and/or IEEE P1547 Officers.

Further Reading

Forum on Inverter Grid Integration Issues (FIGII) (2019): Guide to Selecting Inverters and Settings in Jurisdictions Without Grid Support Functionality Requirements. A Guide to Selecting Inverters and Settings in Jurisdictions Without Grid Support Functionality Requirements is a new document created by the FIGII consortium in April 2019. It is intended to help inform utilities choosing to provide specific requirements to ensure inverters are correctly selected and commissioned. These requirements might exist in utility technical interconnection requirements, technical manuals, interconnection handbooks or addenda. The intended reader is likely a utility engineer tasked with creating or updating such requirements, in light of expanded inverter capabilities now available on the market. Available online at:
