Three-Day Reliability Region Demand Forecast

Download the ISO's hourly demand forecast for each day as forecasted in-day and the preceding two days, broken down by reliability region. The region's transmission system is divided into eight reliability regions that reflect the system's operating characteristics and major constraints. New England's load zones, which represent aggregations of pricing nodes within specific areas, generally correspond to these reliability regions.

 

Note: NEMASSBOST = Northeast Massachusetts and Boston Area Reliability Region; SEMASS = Southeast Massachusetts Reliability Region; WCMASS = Western/Central Massachusetts Reliability Region; % = the reliability region's demand as a percentage of the zonal total. The demand included in the forecast is in megawatts (MW).

Forecasts prior to May 24, 2017, can be found on the Three-Day Reliability Region Demand Forecast Archive.
