Extended Day-Ahead Market revised tariff framework posted

The California ISO has posted the Extended Day-Ahead Market (EDAM) revised tariff framework, which reflects the draft final proposal in an outline format of the tariff, with the objective of establishing an understanding of the relationship between the EDAM design and anticipated tariff provisions. This iteration forms the basis of the first EDAM draft tariff, planned for publication in Q1 2023, which will begin to establish the scope of applicable market rules discussed in the tariff stakeholder process.


The revised tariff framework is available on the EDAM initiative webpage. There will not be a separate comment period associated with the tariff framework, although stakeholders are welcome to include any comments they may have in response to the EDAM draft final proposal.


For all initiative-related information, visit the Extended Day-Ahead Market webpage.
