ERCOT set a new peak for winter demand peak, with record production from batteries and near-record production from solar resources playing a key role.

PJM credited emergency procedures with improving generator performance during a pair of winter storms in January, including a new all-time winter peak of 145,060 MW.

MISO’s Independent Market Monitor said ramping needs north of 10 GW are becoming increasingly common and MISO should expect challenges ahead as its solar fleet expands.

PJM set a record winter peak load Jan. 22, surpassing its previous seasonal peak set in February 2015. PJM officials said actions the RTO and its members took ahead of the cold snap got the system through strained conditions.

MISO expects its in-service solar capacity to grow to 12 GW by the end of winter, a 50% increase over its existing fleet.

MISO doesn’t foresee a scenario where it comes close to risky operations in the upcoming winter.

NYISO expects it will be able to operate reliably, according to the Winter 2024 Operating Study.

The new report argues that discussions about building electrification largely leave out one key issue: how to prepare the grid for the higher demand and new consumption patterns associated with the shift.

MISO’s imminent filing for a new capacity accreditation is a crucial first step to get ready for a more complex and challenging future, executives told attendees during March Board Week.
