Description: This Nodal Protocol Revision Request (NPRR) increases the limitation on the size of the individual Resource comprising an Aggregate Generation Resource (AGR). The current definition of an AGR sets a size limit of 10 MW on the constituent Resources that comprise an AGR; however the overall size of an AGR is limited only by the capacity of the transformer through which the potential AGR connects. Technology has advanced, in particular for reciprocating engines, such that newer, larger, more efficient units are prohibited from enjoying the benefits of registering as an AGR because of the current size limit imposed on the individual Resources that may comprise an AGR. As long as all individual Resources comprising an AGR are of an identical nature as currently required by the Nodal Protocols, the modeling and dispatching of such Resources should be agnostic to the size of the individual constituents, particularly in consideration of the inherent limitation imposed by the transformer to which they are interconnected.
Reason: Market efficiencies or enhancements
