Early Summer Heat
As early summer heat creeped into the northeast in the back half of last week, NYISO saw notable volatility in Zone A as the combination of hydro imports from Canada and high exports to the neighboring PJM drove expensive price spikes sporadically Thursday and Friday.
This could be a hint of things to come later in the summer, particularly as PJM continues to depend on flows from NY on high demand days.
ISONE announced that there is adequate supply to meet forecasted demand this summer.
They note, however, that should extreme heat develop, tighter system conditions are likely to occur which leaves the door open for price volatility in the northeast during substantial heat waves.
