Relative to the results of this study, the 19 IOUs fell into four classes, as shown in Figure 4. The economically efficient utility, SDG&E, stands out as a best-in-class performer. Six other utilities were classified in the Best Practice quadrant: FP&L, TUC, SCE, SPSC, TEC, and HL&P. Several more utilities (em SC, CP&LC, APSC, FPC (em have Best Practice potential if they would place more emphasis on profits.

Strikingly, most of the 19 utilities examined were very inefficient. However, nearly all these utilities exhibited considerable profit potential.
