Fuel Mix Graph

Date: 12/18/2020  
 
 
 

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.

Morning Report

Date: 12/18/2020  
 
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.

Fuel Mix Chart

Fuels Renewables
 

These charts indicate the fuels being used by New England's power plants to generate electricity. Electricity imported from neighboring areas is not included.

 

Fuels in the chart 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 this 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. 

 

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.

Three-Day System Demand Forecast

Date: 12/18/2020  
 

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.
