INITIATIVE:
Intertie deviation settlement

Started: Aug 22, 2018

Leads
Brad Cooper

The purpose of this initiative is to incentivize delivery of awarded energy on interties to increase operational awareness and grid reliability. Increased undelivered intertie resources are causing impacts on market pricing and grid stability. This initiative will analyze the existing intertie decline charge and propose a new settlement methodology for intertie deviations.

 

Outcome:  This initiative introduced a new settlement methodology for intertie deviations. The desired outcome of this initiative is to provide economic incentives for the delivery of intertie resources.  The ISO expects this initiative to lead to more accurate estimates of the net scheduled interchange, increased grid reliability, and accurate market pricing. This new settlement methodology was deployed on Feb. 1, 2021 and activated on Feb. 8, 2021.
