Reason For Revision

ISO was to requested to provide a high-level design proposal for a Nodal Pricing Model (NPM) that can be used to clear energy supply and demand bids for an existing Balancing Authority Area (BAA) one day ahead, in addition to the existing Energy Imbalance Market.

The ISO proposed to leverage its existing Day-Ahead Market (DAM) technology platform, full network model, and data interfaces available in the real-time Energy Imbalance Market (EIM) to provide to EIM Merchants with Day Ahead Nodal Pricing Model. The ISO will provide any participant that elect to utilize Day-Ahead NPM, advisory settlement of Day Ahead Energy and Ancillary Service Schedules.


The updated and new configuration guides supports this advisory settlement feature of the initiative.


The ISO anticipates implementation of the BPM changes on or about 12/16/2020, with an effective Trade Date of 1/1/2021.
