1/ Other energy sources include geothermal, solar, wood, wind, and waste. * = For detailed data, the absolute value is less than 0.5; for percentage calculations, the absolute value is less than 0.05 percent. NM = This value is not available due to insufficient data, inadequate anticipated data/model performance, the percent difference calculation is not meaningful. Notes: Totals may not equal sum of components because of independent rounding. Net generation for jointly owned units is reported by the operator. Negative generation denotes that electric power consumed for plant use exceeds gross generation. Station losses include energy used for pumped storage. Generation is included for plants in test status. Nuclear generation is included for those plants with an operating license issued authorizing fuel loading/low power testing prior to receipt of full power amendment. Central storage is a common area for fuel stocks not assigned to specific plants. Mcf=thousand cubic feet and bbls=barrels. Data for 1997 are final.
