The total amount of energy and the sources of energy the New England region used in 2016 to satisfy all residential, commercial, and industrial customer demand are listed on the ISO website. This “net energy for load” is calculated by adding total generation output within the region with net imports and exports to neighboring regions, then subtracting the energy used to operate pumped storage power plants. The Resource Mix webpage provides a breakdown of generation by fuel type and of imports and exports over individual tie lines that make up last year's net energy for load. Numbers are preliminary until the 90-day resettlement process is complete. This information also is available in spreadsheet form on the Net Energy and Peak Load webpage in ISO Express by month and year dating back to 2000.
