Interconnection Changes

On October 31, 2017, FERC accepted proposed revisions to the ISO New England, Inc. (“ISO-NE”) Transmission, Markets and Services Tariff (“Tariff”) to incorporate a methodology for interconnection request cluster studies, which were filed by ISO-NE, the New England Power Pool Participants Committee, and the Participating Transmission Owners Administrative Committee on behalf of the Participating Transmission Owners (collectively, the “Filing Parties”).  Under the new revisions, which became effective on November 1, 2017, interconnection requests for resources located in the same electrical part of the ISO-NE system and that meet certain other criteria, will be studied together, as opposed to individually.  As part of the stakeholder discussions preceding the filing, ISO-NE developed a strategic infrastructure study to identify the transmission upgrades needed to interconnect remotely-located wind resources in Maine, which will serve as the first cluster study to proceed under the newly-accepted methodology.

On October 25, 2017, FERC conditionally accepted the Midcontinent Independent System Operator, Inc.’s (“MISO”) December 16, 2016 proposed revisions to the MISO Tariff, which were designed to improve the efficiency of MISO’s process for charging interconnection customers for “Quarterly Operating Limit” studies.  FERC directed MISO to provide additional clarity in its proposed Tariff language and submit a compliance filing within thirty days.
