New York solar generation set an all-time peak record April 17, generating 4,809 MW in the noon hour, NYISO told the Operating Committee.

The preliminary results of PJM’s look ahead at the capacity available for this summer and the expected peak loads suggest that about 5.4 GW of demand response could be needed to maintain the 3.5-GW real-time primary reserve requirement.

MISO cautioned it’s likely in for heat waves and drought this summer with a slight chance it navigates a 130-GW peak in July.

MISO reported relatively lower costs and outages in August while it served its annual peak late in the month.

MISO said it managed a milder summer overall compared to previous years, though it weathered two hurricanes and escalated into emergency warnings during a heat wave.

MISO set its 122-GW summertime peak on the unofficial last week of summer, with widespread heat necessitating back-to-back maximum generation warnings.

MISO expects a hot summer and should be able to survive load peaks into the 120-GW range, but the system could be on the brink if a scorching day produces demand near 130 GW.

MISO's August demand rose compared to a year ago, while prices dropped by nearly two-thirds.

MISO officials said they probably could have held off their decision to call a summertime emergency in late August.

MISO instated maximum generation procedures Thursday to manage a pervasive heat wave blanketing its footprint.
