Today’s electric system is almost unrecognizable from the electric system a decade ago. Generation from natural gas and renewables has accelerated to replace the rapid and unprecedented retirement of coal-fired generators. Wind, solar, and geothermal electric generating capacity in the United States has now eclipsed capacities from hydroelectric and nuclear resources combined.

On May 1, 2017, ISO-NE released CELT 2017, its latest forecast for electricity demand in New England. As the independent system operator, ISO-NE is responsible for coordinating electric generation and sales in New England and for ensuring the reliable operation of the region’s electric grid.

In 2014, the U.S. electric system looked remarkably different from how it looked ten—or even five—years ago. In the past year alone, the system nearly doubled the amount of incremental installed capacity from renewables as compared to 2013, saw a 13 percent increase in renewable generation, and reached the lowest level of CO2 emissions since 1996.
