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.
