       Notes: Electricity Net Generation: Electric utility and nonutility values for net versus gross generation may not be summed directly.  Values for net generation from nonutility power producers were estimated using a gross-to-net generation conversion methodology (Electric Power Annual 1996, Vol.  II, "Technical Notes." pp.  110-111)."Average Annual Percent Change" is derived as the nth root of the ratio of the nth-period value to base period value, quantity minus 1 (See Coal Industry Annual 1996, "Technical Notes," p.  247).
