NYISO publishes cleared prices rather than probabilistic forecasts, so no band is shown for them. New York prices spike hard during summer heat and winter gas constraints.
This shows settled real-time prices for New York's major load zones, the day-ahead prices NYISO cleared for the same delivery hours, and any model forecast published alongside them. Day-ahead is a market result, while a model series is a forecast.
New York splits sharply upstate to downstate. Cheap generation sits upstate; most demand sits in New York City and on Long Island, and the transmission between them is limited. When those interfaces bind, downstate clears well above upstate — that persistent basis is the defining feature of the market.
NYISO's day-ahead market is a financially binding auction that clears before delivery. Its prices reflect cleared bids and offers, including expectations and risk preferences. The scorecard reports their divergence from settled real-time prices without calling them a NYISO forecast.

Locational Based Marginal Price — NYISO's term for the price of electricity at a given location, reflecting energy, congestion and losses. It is New York's equivalent of the LMP used in other markets.
Limited transmission into the city, local generation that is more expensive to run, and reliability rules that require capacity to sit inside the load pocket. When the interfaces into downstate bind, the city clears well above upstate zones.
Day-ahead clears in an auction the day before delivery, on expectations. Real-time settles every five minutes on what actually happened. The spread between them is where unforecast outages, weather misses and demand surprises show up.
