By subtracting the numbers in the table above, it is possible to calculate the adjusted value of 

 reserves, depending on which scenario is adopted. 



Reducing the interest rate would lower the value of reserves by $15,014,721 (Scenario la) or 

 $21,827,039 (Scenario lb), depending on what interest rate was used, but assuming that 1,288 

 megawatts of forced outage reserves were required. 



On the other hand, if the amount of reserves were reduced, as proposed in Bonneville's testimony 

 and the 1992 Loads and Resources Study (The White Book), then the effect of the interest rate 

 reduction would be smaller -- it would be computed on 600-800 megawatts rather than 1,288 

 megawatts. 



Scenarios 4 and 5 show the effects of reducing the quantity of DSI forced outage reserve and 

 reducing the interest rate on the turbines.
