SHORT DESCRIPTION:  Issue with Non-Binding Base Points and Locational Marginal Prices

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  June 22, 2016 to current

LONG DESCRIPTION:  ERCOT has detected an issue with the software used to calculate projected non-binding Base Points and Locational Marginal Prices (LMPs).  Look Ahead SCED (LASCED) first failed on June 22, 2016 at 20:50 and has operated intermittently since then; therefore, the following LASCED related reports and dashboard on the Market Information page on ERCOT.com may not have posted or may not have Real-Time Dispatch (RTD) data for any failed LASCED executions in this period through the current time:  

· NP6-971-CD        RTD Indicative Base Points by Resources

· NP6-970-CD        RTD Indicative LMPs by Resource Nodes, Load Zones and Hubs

· NP6-325-CD        RTD Indicative ORDC and Reliability Deployment Price Adders and Reserves

· Real-Time Dispatch Indicative LMPs by Load Zones or Hubs Display  on ERCOT.com

The reports have retry functionality; however, this capability works only when source systems are providing data. 

ERCOT is investigating the root cause and will provide an update when the issue is resolved.
