The continuing promises to reduce OOM requests by the NYISO would seem to be nothing more than empty verbage. I am referring to the continued multitude of OOM dispatches that are requested every day by either ConEd and the NYISO. Any request for generation OOM is bypassing the SCD dispatch algorithm. The requests are so frequent that it makes one wonder if SCD is capable of dispatching the system at all. Generation is consistently requested OOM into any pickup hour whether in the morning or the evening, this can mean one of two things either SCD is significantly flawed and cannot handle any system condition in which the system is marginally stressed or that operator intervention into the dispatch process is for price control and not for system security. The nebulous and overused rationale of "requested OOM for ISO or local security" lacks detail and any rationale. An OOM request is a special exception to the dispatch algorithm as afforded in the tariff to allow resolution of a system condition that SCD cannot resolve. Since these requests are requested so frequently you have to assume that SCD is inherently flawed. Yes the 138 KV modeling may go in service in the near future but will it really reduce the OOM calls. ConEd has a carte blanche to load generation whatever and whenever they want, even when it is not in their transmission district (Roseton OOM dispatch). There is no justification required and clearly it is in their economic interest to request generation OOM. Controls and the capability to audit these requests are required to mitigate the load server with 40% of the New York State load to cease and desist bypassing the SCD dispatch algorithm. The consistent use of the NYPA GTs, the Gilboa generators, etc. are a consistent abuse of a loophole in the tariff that allow interference into the system dispatch unchecked and without any published rationale. I would only assume that if a generator abused the dispatch to the same extent they would have been thrown in mitigation jail a long time ago.
