Lean Burn
A “lean burn” engine uses a relatively lean amount of fuel in the engine’s combustion chamber. On a comparative basis, lean burn engines use less fuel than “rich burn” engines, thereby producing fewer emissions per unit of output. (The Code of Federal Regulations, Title 40, Part 63.6675, defines “lean burn” engines as any engine that
Load Duration Curve (LDC)
A non-chronological, graphical summary of demand levels with corresponding time durations using a curve, which plots demand magnitude (power) on one axis and percent of time that the magnitude occurs on the other axis.

Load Factor (LF)
In context of electricity, the “load factor” refers to the percentage of electricity needed, used or produced over a period of time, relative to the peak (maximum) electric demand or capacity over the same period of time.
