Summary of IEEE P2800 Draft Standard The draft standard harmonizes InterconnectionRequirements for Large Solar, Wind and Storage Plants It is a consensus-based draft developed by over 175Working Group participants from utilities, systemoperators, transmission planners, & OEMs over 2 years You can further influence the draft standard by(1) participating in the IEEE Ballot Pool (by March 3, 2021)(2) supporting adoption of the standard3

Status Quo -- Solar, Wind & Storage Interconnection Requirements Diverse & different requirements acrossvarious jurisdictions requires more effort and time to address Inverter-based resources (IBR) are differentfrom synchronous generators higher (and sometimes lower) capability Requirements may not be balancedSource: https://www.natf.net/ some too stringent & not taking advantage of newcapability5

What to expect from IEEE P2800? Provides Value– widely-accepted, unified technical minimum requirements for IBR– simplification and speed-up of technical interconnection negotiations– flexibility for IBR plant developers not an equipment design standard Specifies– performance and functional capabilities and not utilization & services– functional default settings and ranges of available settings– performance monitoring and model validation– type of tests, plant-level evaluations, and other verifications means, butnot detailed procedures ( IEEE P2800.1 and/or P2800.x) Scope– Limited to all transmission and sub-transmission connected, large-scalewind, solar, energy storage and HVDC-VSC8

Public Review Process OverviewA 60 day Public Review period begins automatically with the opening of the SA BallotThe IEEE SA Public Review process provides an opportunity for any interested party to submit comments on anyeligible initial ballot draft, and obtain responses from the IEEE Working Group.All comments received from the Public Review period shall be considered and responded to. Public Reviewcomments do not have votes associated with them. Consensus is not based on Public Review comments Working Group/Comment Resolution Group will identify in their response if they have determined that theywill make a change in the draft If responses identify a change to the draft, the Public Review commenter can request a revised draft Each public review commenter receives only their responses As normally required, changes to the draft must be recirculated in a SA Ballot recirculation All Public Review comments and responses shall be submitted to RevCom40
IEEE SA Ballot consensus: Response & approval rateIEEE SA Ballot Consensus is achieved when: At least 75% of the ballot group voted (Response rate) The number of Approve votes is 75% or more of the total Approve and Do Not Approve (with Comments) votes.(Approval Rate) Fewer than 30% of the ballot group voted AbstainResponse Rate: If the response rate is not met: The ballot can be extended by the Program Manager (PM) WG Officers and PM can work together to reach out to those that have not responded The response rate must be met in order to continue with the balloting process.Approval Rate: If the approval rate is not met, the entire draft is open for comments on the next ballot (recirculation). During a recirculation ballot, SA balloting group members shall have an opportunity to cast votes or change their previously castvotes.41
SA Ballot Next Steps - Recirculation OverviewWhen is a recirculation ballot required? All unresolved Do Not Approve votes with comments shall be recirculated to the Standards Associationballoting group. All substantive changes made since the last ballot of the proposed standard shall be identified andrecirculated to the Standards Association balloting group. If there are significant changes made to the draftyou may consider opening: The entire draft for comments on the next ballot recirculationThe recirculation for a longer period of timeRecirculation ballot(s): Minimum of 10 days During a recirculation ballot, SA balloting group members shall have an opportunity to cast votes or changetheir previously cast votes Once the proposed standard has achieved 75% approval, comments in recirculation ballot(s) shall be basedon: Only on the changed portions of the draft Portions affected by the changes Portions subject to unresolved comments associated with Do Not Approve votes.42
SA Ballot – Comment Resolution Guidelines The Comment Resolution Group will review and consider all comments that are received by the close of theballot. This includes comments received outside of the myProject system and mandatory coordinationcomments. Evidence of Consideration Comments that advocate changes in the proposed standard, whether technical or editorial, may be accepted,revised, or rejected. Until the proposed standard has achieved 75% approval, comments can be based on any portion of the proposedstandard Comments not based on the proposed standard may be rejected and deemed out-of-scope of the standardsballoting process by the Standards Committee.Comments received by the WG after the close of the ballot Shall be acknowledged and may be considered The Standards Committee shall acknowledge the receipt of these late comments Take action as the Standards Committee deems appropriate. For more information, see the IEEE SASB Operations Manual Clause 5.4.3.3 -Comments in the ballot43
