ELECTRIC UTILITY DEREGULATION

In recent years, major industries in the United States have been dereg ulated - for example, telecommunications, airlines, and banking - and now the winds of change are blowing through the electric utility indus try. Federal legislation has opened up the nation's transmission grid and has helped create a thriving independent power generation sector. Large companies and municipalities are finding ways to bypass traditio nal utilities and find cheaper power sources. But the experts do not a gree on how much change is good for the country and how fast it should occur. Some utilities maintain that aggressive deregulation would for ce them to write off investments they had made to satisfy regulators i n the past - and leave them with stranded costs. Other constituencies debate fair compensation of grid owners for transmitting the electrici ty. Still others are concerned about ensuring that residential and sma ll-business customers share in any gains from an open market. Thomas R .
