      Every day, ISO New England publishes this summary of factors affecting the power system for the next seven days, including weather, generating capacity, and peak demand. The forecast is used to identify capacity deficiencies several days in advance and triggers the commitment of generators with start times greater than 24 hours. For today's forecast, see the Morning Report
