IEEE 1547™-2018 Adoption Tracker
The Institute of Electrical and Electronics Engineers 1547™-2018 Standard (IEEE 1547-2018) is a technical standard that establishes how distributed energy resources (DERs)—like solar and energy storage—can connect to the grid. In particular, it establishes interconnection requirements for smart inverters, which have advanced “grid support” functions that can help the grid accommodate higher levels of renewable energy. IREC’s IEEE 1547-2018 Adoption Tracker provides regulators, utility staff, and other DER stakeholders with visibility into which jurisdictions have adopted the IEEE 1547-2018 standard.
IREC’s IEEE 1547™-2018 Adoption Tracker is intended to be a resource for Public Utilities Commissions, utility personnel, and other DER stakeholders interested in reviewing the standard’s adoption status across states and regional transmission organizations in the U.S. and Canada.
Explore the tracker below, or read on for more information on the data it contains, how to use it, and IREC’s schedule for updating the tracker with new information. You may also download the spreadsheet using the submission form to the right (or at the end of this page in some browsers).
About the IEEE 1547-2018 Adoption Tracker
The Adoption Tracker focuses on whether a particular entity has selected an adoption date by which certified inverters (UL1741.SB) are required in new application submissions. It compiles references from decision-making entities related to their efforts to adopt the IEEE 1547-2018 standard. The tracker also includes inverter performance criteria, if selected and made public by a particular region or state entity. To learn more about the standard or the selection criteria, please review IREC’s Making the Grid Smarter report and Decision Options Matrix for IEEE 1547-2018 Adoption.
How to Use the Adoption Tracker
The tracker is a spreadsheet organized into two tabs: “Legend” and “Adoption Tracker.”
- The “Legend” tab provides detailed descriptions of each of the columns within the “Adoption Tracker” tab.
- The “Adoption Tracker” tab contains the information on adoption status, which is organized in alphabetical order according to the name of the regional entity or state.
To use the tracker, find the row (or use Google Sheets filtering function) corresponding to the state or region you are interested in finding the adoption status for. After identifying the correct row, review the “Adoption Status” and “Adoption Date” columns for information on the status of their efforts to adopt IEEE 1547-2018 for inverter-based generators.
Directly adjacent to this are the “References” columns including up to three references pulled from the entity’s website with direct links and quotes that informed the adoption status and date determination.
To the right of the “References” columns is a brief “Notes” section that includes additional information on the status determination.
Near the right-most edge of the spreadsheet are a series of columns containing the entity’s selected inverter settings across four category areas which are described in more detail in the “Legend” tab.
Revision Schedule & Submission of Updates
IREC will update the entire tracker on a quarterly basis, but will seek to remedy inaccuracies identified by stakeholders as soon as we are made aware of them. If you have any questions, concerns, status corrections, or improvement suggestions, please contact our team at [email protected].
