Order 1920 | Order 1920-A | Order 1920-B

Order No. 1920 requires transmission providers to submit two compliance filings.  The first compliance filing encompasses all of Order No. 1920’s requirements except for those related to interregional transmission coordination.  The second compliance filing concerns only interregional transmission coordination requirements for transmission providers.  Since the Commission issued Order No. 1920 and subsequent rehearing orders, and following motions filed by transmission providers or Relevant State Entities, the Commission has provided extensions of time to submit both compliance filings.  The new deadlines are summarized by transmission planning region in the table below.

Order No. 1920 additionally requires transmission providers to hold a six-month Engagement Period during which Relevant State Entities may participate in a forum for negotiating (1) an ex ante cost allocation method or methods for selected Long-Term Regional Transmission Facilities; and/or (2) a State Agreement Process – a process by which one or more Relevant State Entities may voluntarily agree to a cost allocation method for Long-Term Regional Transmission Facilities (or a portfolio of such Facilities) either before or no later than six months after the facilities are selected in the regional transmission plan for purposes of cost allocation.  In Order No. 1920-A, the Commission stated that it will grant an extension of the Engagement Period for up to six additional months, if Relevant State Entities request additional time.  The table below also notes where the Commission has granted Relevant State Entities’ requests to extend the Engagement Period.
