How these are worked out

Net generation and fuel burned are the monthly figures EIA publishes in its bulk electricity file, from the plant's Form 923 reports; a year is the sum of its months. Capacity factor is a full year's net generation over today's nameplate capacity times the hours in that year (8,784 in a leap year), so a plant uprated or partly retired since reads against its current size; heat rate is fuel burned over net generation, for plants that burn fuel. A year with fewer than twelve months stated has no capacity factor, and a value outside the plausible range is left blank rather than shown. By month, the charts apply the same rules to each month's own hours and fuel.
