New York’s real-time LMP hit $3,000/MWh Tuesday as heat wave outpaced grid flexibility

On Tuesday New York’s real-time locational marginal price (LMP) spiked to nearly $3,000/MWh—up from ~$100 just an hour earlier.

Evening demand stayed high while solar generation fell sharply after 6 PM, forcing the grid to fire up expensive fossil-fueled peakers.
