This graph shows electricity demand from these perspectives:
Forecast: The most recently-published forecast of electricity demand, updated as needed and at least twice daily.
Actual: The real-time electricity usage on New England’s bulk power grid, updated every 5 minutes.
Cleared: The demand for electricity that cleared in the Day-Ahead Energy Market for the selected day.
Prior-Day: A record of the demand forecast published prior to the deadline for bids and offers in the Day-Ahead Energy Market for the selected day.
Actual Including Pump Load: Real-time electricity usage on the bulk power grid, including demand from pump load resources. Actual Including Estimated Behind-the-Meter Solar: An estimate of real-time electricity usage in New England, including actual usage on the bulk power grid and estimated output from from behind-the-meter solar resources.
This graph charts the types of resources meeting consumer demand for grid electricity in New England, by megawatt, throughout the course of a day.
Resources in the graph include those using natural gas, nuclear, coal, oil, hydro, other, and renewable resources to generate electricity within New England, as well as net imports from neighboring regions.
Resources in the renewable category include: landfill gas, methane, refuse, solar, steam, wind, and wood. Net import values represent the electricity being imported, less that being exported, across the region’s tie lines.
Hydro is not included in the renewable category primarily because the various sources that make up hydroelectric generation (i.e., conventional hydroelectric, run-of-river, pumped storage) are not universally defined as renewable in the six New England states.
The other category contains the output of energy storage devices (excluding pumped hydro) and demand response.

This graph displays estimated average carbon dioxide (CO2) emissions, in metric tons, from New England power plants in real time throughout the course of the day. The estimates are for resources using oil, refuse, wood, coal, landfill gas, or natural gas to generate electricity. The graph also shows the sum of estimated average CO2 emissions from these resources as a total estimate for the region’s bulk power system.
Other resource types—nuclear, hydro, wind, solar, and energy storage devices—do not produce CO2 emissions. The graph does not include emissions estimates for electricity imported from neighboring areas because the resource types producing this electricity are unspecified.

This forecast is ISO New England's hourly systemwide demand forecast for today and the next two days. This is the expected amount of electricity to be used in the New England Balancing Authority Area: Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire, and most of Maine. The forecasted demand incorporates the demand-reducing effects of regional energy-efficiency measures acquired through the Forward Capacity Market, distributed generation, and a reduction in peak load that can be expected from the region's behind-the-meter photovoltaic installations at homes and businesses. The forecast is updated twice daily at 6:00 a.m. and 10:00 a.m. eastern prevailing time.
These charts indicate the type of resources being used to meet consumer demand for grid electricity in real-time.
Resource types in the chart include those using natural gas, nuclear, coal, oil, hydro, other, and renewable resources to generate electricity within New England, as well as net imports from neighboring regions. Resources in the renewable category include: landfill gas, methane, refuse, solar, steam, wind, and wood. Net import values represent the electricity being imported, less that being exported, across the region’s tie lines.
Hydro is not included in the renewable category primarily because the various sources that make up hydroelectric generation (i.e., conventional hydroelectric, run-of-river, pumped storage) are not universally defined as renewable in the six New England states.
The other category contains the output of energy storage devices (excluding pumped hydro) and demand response.
A resource type may appear in the legend but not in the charts if it is producing a very low amount of electricity. If a resource type is not producing any electricity, it will not appear at all.
The Marginal Fuel is the fuel currently being used by the resource that will be dispatched to generate the next additional megawatt of energy on the New England power system.

Produced daily, the Morning Report provides the ISO's best estimate of expected capacity available to meet peak-hour electricity demand and reserve requirements — key parameters used to operate the power system reliably.
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.
