This graph shows electricity demand from these perspectives:

 

   ACTUAL: The real-time electricity usage within New England, updated every 5 minutes.

   FORECASTED: The most recently published forecast of electricity demand, updated as needed and at least twice daily.

   CLEARED: The demand for electricity which cleared in the Day Ahead Energy Market for the selected day.

   PRIOR-DAY: A record of yesterday’s demand forecast that was published prior to the deadline for bids and offers in the Day Ahead Energy Market.

    PUMP LOAD: Off-peak electric energy used to pump water into a pumped-storage unit's storage pond.

   *NEW* BEHIND-THE-METER SOLAR: An estimate of New England’s total electricity usage from both grid and behind-the-meter resources.

 

ISO New England predicts electricity usage based on daily and seasonal patterns, as well as weather and distributed generation resources, not connected to the regional power grid.
