6. Summary of Rate Increase for Region I
Golden State's applications request the rate increases shown in Table 1, above, to counter the effects of substantial increases in major expense items and plant investment since the last GRCs for these districts.4 The last two columns show our adopted changes for test year 2008. The RCP for Class A water utilities requires Golden State to list for each seven districts the five most significant factors driving its requested increases. Some of those factors having the greatest effect on rates are the increase in allocated General Office expenses from A.06-02-023, 5 cost of capital, labor expenses, supply expenses, depreciation expenses, rate base, cost of chemicals, regulatory expenses, purchased power, purchased water expenses, and expenses associated with water conservation.
4 Requested and adopted increases are shown for 2008. For 2009 and 2010, the requested increases are only estimates based on escalation factors.
5 This proceeding does not adjudicate Golden State's General Office costs for its headquarters in San Dimas, California. General office costs were last reviewed in A.06-02-023 and recently determined in D.07-11-037.
