ISO Minute: Explore the energy supply forecast that’s key to winter grid operations 

ISO Minute is a video series featuring ISO New England employees speaking about their experiences working for the region’s independent system operator and supporting the safe and reliable transition to clean energy. 

In this ISO Minute, Mallory Waldrip, supervisor of Operations Energy Analytics, sheds light one of ISO New England’s key tools for winter operations: the 21-Day Energy Assessment Forecast and Report.  

This innovative three-week outlook analyzes a host of variables to identify potential energy shortfalls, allowing the region to take steps to prevent them or lessen their impact. 

“Every week in the winter, we produce this 21-day energy assessment, which is something that we pride ourselves on here as it’s a tool that we’ve built in-house,” Waldrip says. 

The report examines whether the region’s electricity supply could fall below anticipated consumer demand and required operating reserves during any hour in the upcoming three-week period. Find the latest report and an archive of past analyses here.
