Extended Day-Ahead Market: Working drafts of draft tariff language documents posted

In response to requests from stakeholders during the recent Extended Day-Ahead Market (EDAM) draft tariff language workshops, the California ISO has posted the working drafts of of the draft tariff language documentation.The working drafts are available on the EDAM initiative webpage.


The ISO will not be accepting written comments on the working drafts, as the documents are intended to be a resource for stakeholders to review initial revisions based on stakeholder comments and tariff workshop discussions.


The ISO will post a complete revised draft of the EDAM tariff language documentation in early June, in which stakeholders will have an opportunity to provide any additional comments they may have prior to when the ISO files the tariff language with the Federal Energy Regulatory Commission.


Please contact Isabella Nicosia at or with any questions.
