About this data

Each row is one five-minute interval of New England system load, with native load, active demand response and a total adjusted for behind-the-meter solar. These are market-wide totals and do not describe individual load zones. People use the series to follow New England demand through the day and see how solar and demand response change the picture.

What people use it for

  • Follow ISO-NE demand through the day
  • See the effect of behind-the-meter solar on load
  • Check active demand response
