[1] Includes a small number of generators for which waste heat is the primary energy source. [2] Includes binary turbines. W = Withheld to avoid disclosure of individual company data. Notes: •See Glossary reference for definitions. • Totals may not equal sum of components because of independent rounding. • Heat rate is reported at full load conditions for electric utilities and independent power producers. • The average heat rates above are weighted by Net Summer Capacity. • In 2010, EIA changed the way it treated blank values in its methodology for calculating average heat rates.
