SHORT DESCRIPTION:  Updated Implementation Details for NPRR626, NPRR665, NPRR645, and Other Binding Document (OBD)

INTENDED AUDIENCE:  ERCOT Market Participants and Settlement Personnel

DAY AFFECTED:  June 25, 2015

LONG DESCRIPTION:   Effective June 25, 2015, ERCOT will implement Nodal Protocol Revision Request (NPRR) 626, Reliability Deployment Price Adder (formerly “ORDC Price Reversal Mitigation Enhancements”), NPRR665, As-Built Clarification of Reliability Deployment Price Adder, NPRR645, Real-Time On-Line Capacity Revisions, and revisions to Other Binding Document (OBD), Setting the Shadow Price Caps and Power Balance Penalties in Security Constrained Economic Dispatch.

·         Responsive Reserve Manual Deployment Extensible Markup Language (XML) Message

XML message sent to Load Resources other than Controllable Load Resources for manual deployment of Responsive Reserve Service will be updated to show a value (MW) equal to the telemetered net power consumption minus the telemetered Low Power Consumption (LPC).  Currently, the XML message shows a value (MW) equal to the Ancillary Service Resource Responsibility for Responsive Reserve (RRS) Service.

·         New ICCP Telemetry Points

NPRR626 adds following new telemetry points, as shown below, to communicate Real-Time On-Line Reliability Deployment information to the market using Inter-Control Center Communications Protocol (ICCP). For any questions, please contact Client Services to get the ERCOT ICCP Support team help.

a.    Real-Time On-Line Reliability Deployment Price Adder ($/MWh)

b.    Total Sum of RUC-committed and RMR Units’ LDL (MW)

c.    Total Deployed RRS MW from Load Resources  (MW)

d.    Total Deployed ERS MW (MW)

e.    Total Online Resources’ LASL (MW)

f.     Total Online Resources’ HASL (MW)

 

·         New Reports:

There are no new reports associated with these NPRRs, however the new Reliability Deployment Price Adder is being added to existing reports and the report names are changing as part of the NPRR626 implementation. Additional columns are also being added to some reports, as follows:
