FERC Issues Ruling on Interregional Order 1000 Coordination

Contact: Patrick Damiano

On December 18, 2014, FERC issued its ruling on interregional coordination pursuant to Order 1000 pertaining to the four western planning regions (ColumbiaGrid, California ISO, Northern Tier Transmission Group, and WestConnect). ColumbiaGrid's jurisdictional transmission providers' (i.e. Avista, MATL, and PSE) compliance filings are due within 60 days of issuance of the order, such that the filings will be due no later than February 17, 2015. Bonneville Power Administration was also addressed in the order, though they are not subject to FERC's jurisdiction.

The FERC order was generally favorable in that the majority of the substance of the interregional compliance filings of the jurisdictional transmission providers of ColumbiaGrid was accepted by FERC. There were however, several items that the Commission directed the jurisdictional transmission providers of ColumbiaGrid to address, including directives articulated in paragraphs 26, 27, 83, 159, 166, and 167 of the order. A copy of the FERC order can be found at

Leading up to the February 17 compliance date, ColumbiaGrid will be working with its planning parties, particularly the three jurisdictional transmission providers, and the other three western planning regions (California ISO, Northern Tier Transmission Group, and WestConnect) to address the directives of the FERC order.

On a related matter, a copy of the First Amended and Restated Order 1000 Agreement can be found at and other interregional Order 1000 information at .

"Chelan PUD is a strong supporter of ColumbiaGrid and the work that’s accomplished through the transmission Planning and Expansion Functional Agreement (PEFA). As a result of that process, the mid-C utilities (Chelan, Grant and Douglas PUDs) and Bonneville Power Administration were able to reach an agreement that defined the need for a new transmission line, as well as determine who will construct, own and pay for the facility. Those difficult decisions were made successful through the expert and independent expertise of the ColumbiaGrid staff."
