Rate Base Adjustments Not Needed in Stable Economy
Citing a "relatively stable economy," the Utah Public Service Commission (PSC) has reaffirmed its preference for a historical test period in setting utility rates. It rejected a proposal by Mountain Fuel Supply Co., a natural gas local distribution company (LDC), to employ a projected test year in its current rate case. The LDC argued that the adjusted expense and revenue figures would better reflect customer growth as well as the effects of a newly established early retirement program.
