NOTICE TYPE: M-D012326-01 Operations

SHORT DESCRIPTION: Investigation of Incorrect Projected Non-Binding Prices, Base Points and Awards

INTENDED AUDIENCE: All Market Participants

DAYS AFFECTED: Under investigation

LONG DESCRIPTION: ERCOT identified an error affecting projected, non-binding Real-Time prices, Base Points, and Ancillary Service awards for some Security-Constrained Economic Dispatch (SCED) intervals. For example, SCED is not capping the non-binding prices, exclusive of congestion, at the effective Value of Lost Load (VOLL).

This issue does not affect binding SCED results. All binding Real-Time Locational Marginal Prices (LMPs), Market Clearing Prices for Capacity (MCPCs), Base Points, and Ancillary Service awards remain accurate. The error affects only the 60-minute forward projections posted on the ERCOT website and published in MIS reports.

ERCOT is investigating the root cause and will communicate the solution and implementation timeline after confirming both.
