NYCA (New York Control Area)

The New York Control Area is the footprint NYISO balances: all of New York State, divided into 11 load zones lettered A (West, around Buffalo) through K (Long Island). Statewide load, the NYCA total, is the sum of the 11 zones, and the hour it peaks each summer sets ICAP tags. Zone prices differ because transmission between upstate generation and downstate load congests. Zone J (New York City) routinely clears at multiples of the western zones.
