Fuel Mix Graph

Date: 09/28/2016  
 
 
 

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 chart include: coal, hydro, natural gas, nuclear, oil, and renewables. Fuels in the renewable category include: landfill gas, refuse, solar, 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.

Click the gear icon in the upper right corner of portlet to view renewables only; click on the export button to view the raw chart data in CSV format.

Morning Report

Date: 09/28/2016  
 
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
 

This chart indicates 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, 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.

A fuel may appear in the legend but not in the pie chart if it is producing a very low amount of electricity. If a fuel is not producing any electricity, it will not appear at all. Click on the export button in the upper right corner of the portlet to view the raw chart data in CSV format.

Three-Day System Demand Forecast

Date: 09/28/2016  
 

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 forecast is updated twice daily at 6:00 a.m. and 10:00 a.m. eastern prevailing time.
