ISO New England Regulation Capacity and Regulation Service Settlement Has Moved to 5-Minute Interval as-of December 1, 2017

Monica Jha
Director of Product, Northeast Markets

Per its Sub Hourly Settlements (SHS) Project, ISO New England adapted the settlement interval from hourly to every 5-minutes to encourage quicker responses to dispatch instructions.

The alignment of real-time dispatch instruction and pricing intervals resulted in generators, load resources and external transactions to settle at 5-minutes for Real-Time Energy, Regulation, Reserve and Net Commitment-Period Compensation Charges (NCPC).  The transition to 5-minute settlement interval went live on March 1, 2017.

The 5-minute regulation capacity and regulation service settlement went live on Dec 1, 2017.  At that time, ISO-NE made revisions to the MIS report descriptions, templates and sample files for the following reports (complete details can be found on the MIS Report Descriptions, Templates, and Samples web page):

 

  • SD_REGDTL: Retired, effective 12.01.2017
