1 More than 4% of total generation was imported from neighboring systems in New York, New Brunswick, and Quebec. No data are available on the relative contribution of individual fuel sources to imported power.

2 Many generating units are capable of burning more than one fuel. No data are available on the relative contribution of individual fuel sources to total generation by these facilities.

3 Hydroelectric generation includes output from pondage, pump storage, and run-of-river facilities.
