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.
