Description: This Nodal Protocol Revision Request (NPRR) updates the Protocols to ensure that ERCOT issues Market Notices to Market Participants contemporaneously with ERCOT’s activities with Reliability Must-Run (RMR) Unit and Must-Run Alternative (MRA) Resource owners.
Reason: Presently there is an information gap for non-RMR Entities which can impact business strategies for bilateral energy contracts, Congestion Revenue Rights (CRRs), and participation in the Day-Ahead Market (DAM). The asymmetrical information provision under the existing Protocols provides potential advantage to some Entities and potential disadvantage to others.
