ESIG with support from Elevate Energy Consulting, and in collaboration with Berkeley Lab and EPRI, is supporting the U.S. Department of Energy (DOE) initiative to facilitate the Forum for the Implementation of Reliability Standards for Transmission (FIRST) as part of the DOE’s Interconnection Innovation e-Xchange (i2X).

To ensure the reliable and secure operation of clean energy resources connected to the electric grid, interconnection standards need to address inverter-based generator capabilities, expected performance, cybersecurity requirements, and other relevant issues. Some of these standards, such as Institute of Electrical and Electronics Engineers (IEEE)-2800, have been developed, but still need to be widely adopted and implemented. Other standards, as well as procedures for assessing and verifying plant conformity with them, have yet to be developed.
The U.S. Department of Energy (DOE) Interconnection Innovation e-Xchange (i2X) Forum for the Implementation of Reliability Standards for Transmission (FIRST) facilitates the adoption of new and recently updated standards relevant for interconnected clean energy resources like solar and wind energy. The Forum convenes industry stakeholders to enable easier and more harmonized implementation of these interconnection standards.i2X FIRST addresses the solutions related to interconnection standards (4.2 to 4.9) identified in the DOE Transmission Interconnection Roadmap. i2X FIRST covers practices outlined in the draft of IEEE P2800.2 and best practices from early adopters of the IEEE 2800 standard. Additionally, ongoing North American Electric Reliability Corporation (NERC) standard revision efforts related to Federal Energy Regulatory Commission (FERC) Order 901 are discussed to ensure alignment with IEEE 2800 adoption. Feedback gained through i2X FIRST will help shape new standards development processes.Please share your feedback on Season 1 of the i2X Forum meetings!

Download the i2X FIRST Season 1 Recap Summary

This document summarizes season 1 of the i2X FIRST initiative, which provided a foundational exploration of IEEE 2800-2022, its core requirements, and early industry experiences with implementation. Implementation ranges, for example, from original equipment manufacturers (OEMs) readying their inverter products to be compatible with the standard’s technical minimum plant-level requirements; over plant developers and generator owners (GOs) improving the design of new IBR plants to have specified capabilities; to transmission owners (TOs), independent system operators (ISOs), or regional transmission organizations (RTOs) adopting the standard, for example via incorporation into their facility interconnection requirements documents. The forum also addressed ongoing efforts under IEEE P2800.2 to develop robust test and verification procedures to support IBR plant-level capability and performance conformity assessments.

This document provides full notes for all meetings held during season 1 of the i2X FIRST initiative. Season 1 of the i2X FIRST initiative provided a foundational exploration of IEEE 2800-2022, its core requirements, and early industry experiences with implementation. It also addressed ongoing efforts under IEEE P2800.2 to develop robust test and verification procedures to support IBR performance conformity assessments. The forum included broad participation from over 1,225 unique participants across a diverse set of stakeholders including IBR developers, utilities, system operators, original equipment manufacturers (OEMs), and consultants.

Season 1 i2X Monthly Meetings
