Marginal fuel type: natural gas
Generating capacity (summer 2009): 36,820 MW
Very little new generation has been brought on line recently in New England. The ISO states that it, “…has adequate installed capacity to meet regional capacity needs through 2009. The ISO is optimistic that adequate demand and supply resources will be purchased and installed in time to meet the projected capacity needs and the resource adequacy requirements for 2010 and beyond.”
Capacity reserve (summer 2009): 9,600 MW
Reserve margin (summer 2007): 35.3%
