This graph charts the fuels New England's power plants are using to generate electricity throughout the course of a day, by megawatt. Electricity imported from neighboring areas is not included.
Fuels in the graph include: natural gas, nuclear, coal, oil, hydro, other, and renewable. Fuels in the renewable category include: landfill gas, methane, refuse, solar, steam, wind, and wood.
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 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.

A fuel may appear in the legend but not in the charts if it is producing a very low amount of electricity. If a fuel 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.
