Reason For Revision
 

The frequency and magnitude of excess behind the meter production (EBTMP) – periods when a customer’s behind the meter resources generate output above host load – are increasing as more behind the meter resources are integrated into the system. The treatment of EBTMP directly impacts downstream financial settlement allocations based on Gross Load figures that scheduling coordinators submit to the ISO. Because of these settlement impacts, it is critical that scheduling coordinators report Gross Load values to the ISO in a consistent manner.

This initiative aims to address the issue of excess behind the meter production reporting because some entities are reporting Gross Load to the ISO by netting the EBTMP and others are reporting without netting the EBTMP. In order to enforce consistent reporting, the ISO will clarify the tariff definition of Gross Load and establish a new tariff definition for EBTMP, and it will specify how EBTMP will be reported to the ISO. The determination for Unaccounted for Energy has also been updated.

The effective date of the changes is 1/1/2021 and the anticipated implementation date is 9/29/2020.
