The newest v4.1 Guide (July 2023) has added the following language - "Note that while the previous versions of LEED allowed for EAC arbitrage for on-site systems, LEED v4.1 requires the owner to retain the environmental attributes of renewable energy that is generated on-site in order to for the generation to qualify for the credit."
The prior versions of the v4.1 guide that I can find seem to be silent on this.
So my question is ... I am working on a project registered prior to ANY v4.1 version issuance date. Can I use an old version of v4.1 for this credit, and utilize EAC arbitrage, or is that banned for all v4.1 projects, regardless?

In general you are required to meet the criteria in place at the time that you registered the project. Sounds like you can certainly make the case that you do not have to meet the new criteria however when a version of LEED is silent on an issue the reviewers have to step in and make a determination about how to address those issues. Not sure if they have done so on this one or not. The v4 criteria did allow for the replacement of the RECs that were sold.
