Joint Information Meetings on Regional Cost Shared Projects

Pursuant to the FERC order in Docket No. ER13-2379, transmission owners with transmission projects that utilize a regional cost sharing mechanism are required to hold joint meetings to enable all interested parties to understand how those transmission owners are implementing their formula rates for cost recovery of such projects.

Formula Rate Protocols

Postings are organized by rate year. For transmission owners using a forward-looking Attachment O, rates are updated each January. For Tranmission owners using a historical Attachment O, rates are updated each June. The initial rates for new transmission owners (or those that switch from a historical to forward-looking Attachment O) may be added outside of this cycle, but will be included in the normal update cycle thereafter.
