engine fueled by landfill methane gas.
Notes:
· Totals may not equal sum of components
because of independent rounding. · Sufficient
data are not available to determine which units can burn more than one energy
source without an appreciable loss in Capacity when burning the alternate
energy source. · This table provides a distribution
of generating capacity by energy source that the units are capable of using.
Plants sold or transferred to nonutilities are not included in these data.
