^aLight oil is distillate fuel oil, and heavy oil is residual fuel oil.
Note: EIA began collecting nonutility data in 1989 and is only final through 1998. Nonutilities do not directly report the split between light and heavy oil generation.
Sources: Energy Information Administration, Form EIA-759, “Monthly Power Plant Report”; Form EIA-860B, “Annual Electric Generator Report—Nonutility”; and Form EIA-867, “Annual Nonutility Power Producer Report.”
