For Phase 2 of the Nodal Pricing Model (NPM) proposal, it was requested that CAISO expand from Phase 1 to include Ancillary Service features leveraging the existing Day-Ahead Market (DAM) technology platform, full network model, and data interfaces available in the real-time Energy Imbalance Market (EIM) to provide EIM Merchants with NPM.
The CAISO will provide any participant that elects to utilize DA-NPM with advisory settlements inclusive of Ancillary Services (Spin, Non-Spin, Regulation Up, Regulation Down).
The updated configuration guides GMC Bid Transaction Fee 4515 5.7 and Pre-Calc Ancillary Services 5.11 supports this advisory settlement feature of the initiative.
CAISO anticipates implementation of the BPM changes on or about 2/16/2022, with an effective date of 2/16/2022.
