| NM = Not meaningful due to large relative standard error or excessive percentage change. Notes: See Glossary for definitions. Values for 2025 are preliminary. Values for 2024 are final. See Technical Notes for a discussion of the sample design for the Form EIA-923. Negative generation denotes that electric power consumed for plant use exceeds gross generation. Totals may not equal sum of components because of independent rounding. Percentage change is calculated before rounding.
