NPRR #576 · Revision Request

NPRR576  Changing Non-Spin Service to be Dispatched by ERCOT (formerly "Changing Non-Spin Service to an Off-Line Service")

Approved Urgent sponsor GDF Suez NA Inc. posted 2013-10-24 ercot.com
ReasonCurrently Non-Spin can be provided by On-Line Generation Resources which are always available to Security-Constrained Economic Dispatch (SCED). This creates several issues both from a reliability and market perspective. It reduces reliability because it is being deployed before it is needed therefore no longer there when it is truly needed; and if Entities know this is coming in, they have less MWs in SCED, thus the total available response in system is lower at all times. From a market perspective On-Line Non-Spinning reserves create a non-linearity in prices, thus preventing true scarcity prices as the large amount of On-Line creates an artificial buffer in the supply stack.

Summary
This Nodal Protocol Revision Request (NPRR) continues to allow On-Line Non-Spin, but places it behind the High Ancillary Service Limit (HASL). This NPRR also proposes the reinstatement of a minimum offer floor for On-Line Non-Spin, but leaves the determination of its value (value of X) to TAC.
