FERC Accepts SPP, SERTP Order No. 1000 Interregional Filings, Affirms ISO-NE Order
The Federal Energy Regulatory Commission (FERC) has continued the implementation of Order No. 1000 by accepting interregional filings by Southwest Power Pool Inc. (SPP) and utilities in the Southeastern Regional Transmission Planning Process (SERTP) region. In a separate order, FERC largely affirmed its May 2013 order accepting ISO New England’s (ISO-NE) regional planning and cost allocation process, and it found the grid operator’s proposed revisions partially comply with the directives in the first order.
Order No. 1000 requires neighboring transmission planning regions to identify and jointly evaluate interregional transmission facilities, which are facilities located in two or more neighboring transmission planning regions that may be more efficient or cost-effective solutions to the transmission needs of individual regions. It does not require an interregional transmission plan or interconnection-wide planning.
