NPRR532 enables participation in the Non-Spinning Reserve (Non-Spin) Service market for Load Resources. NPRR555 and NPRR591 enable Demand response from Controllable Load Resources, as re-defined, to be Dispatched by Security-Constrained Economic Dispatch (SCED) based on a Real-Time Market (RTM) Energy Bid. New ICCP Telemetry Points: NPRR555 adds the following new telemetry points to communicate Controllable Load Resources "Resource LMP", "SCED Base Point", "Updated Desired Base Point (UDBP)" and Congestion Flag values to the market using Inter-Control Center Communications Protocol (ICCP). Similar to the Generating Resources, Controllable Load Resources Updated Desired Base point (UDBP) is a linear interpolation from the current UDBP to the new SCED CLR base point over base point ramp duration. Controllable Load Resources Congestion Flag indicates that SCED has dispatched a CLR available for SCED dispatch below HDL similar to the one used for Generation Resource. For any questions, please contact Client Services to get the ERCOT ICCP Support team help. Controllable Load Resources LMP ($/MWh) Controllable Load Resources SCED Base Point (MW) Controllable Load Resources Updated Desired Base Point (MW) Congestion Flag (SBBH). New and/or updated Defined Resource Status for Load Resources: The following Resource Statuses for Load Resources are to be used for Current Operating Plan (COP) and/or Real-Time telemetry purposes for NPRR555: * ONRGL - Available for Dispatch of Regulation Service by Load Frequency Control (LFC) and, for any remaining Dispatchable capacity, by SCED with an RTM Energy Bid; * ONCLR - Available for Dispatch of Response Reserve (RRS) Service, Non-Spinning Reserve Service or for energy as a Controllable Load Resource by SCED with an RTM Energy Bid; * ONRL - Available for Dispatch of under-frequency relay-type RRS Service; and * OUTL - Not available; The following reports are being added to the Market Information System (MIS) and/or ERCOT.com: Name EMIL ID Rpt.

The type will appear in the Market Manager under the "Resource-Specific" tab, and the XML format is specified by the attached XSD documents. The MOTE environment will be available for testing submissions starting on Tuesday, April 29, 2014.
